D. When Mark uses a table all items below will automatically shift down or up when needed.
The following statements regarding XForms are true, except for which one:
XForms is based on XML formatted specification.
XForms includes a presentation layer for designing forms.
XForms models typically consist of data, binds, and submissions.
XForms is a W3C recommendation.
David has built a form that uses XForms Panes, but he cannot access the fields and labels insidea pane. Why can't David access the fields and labels, and how can he correct this problem?
XForms Panes are actually iframes inside an XFDL form. The way to reference the values ofthe items inside the pane is throughthe XFormsdata model.
XForms Panes are insulated from the XFDL items outside of them, as the panes are given adynamically generated SID at runtime. XForms Panes are unique in that they require the reference to contain ".PANE" in order to access theitemsinside the pane. For example:PAGE1.AddressPane.PANE.FIELD1.
XForms Panes are insulated from the XFDL items outside of them, as the panes are given adynamically generated SID at runtime. The bestway to reference the values of the items inside thepane is through the XForms data model.
XForms panes are actually iframes inside an XFDL form. The best way to access the valuesinside the items within the XForms pane is to usethe API.
Which of the following tabs can you NOT remove or hide within the IBM Forms Designer?
Webform Server Tab
What does the following statement represent?
This button allows users to enclose files into one of three datagroups or folders: Images_Asia,Images_Eur, Images_SAmer.
This button allows users to enclose files as one of the three file names: Images_Asia,Images_Eur, Images_SAmer.
This button allows users to enclose files with the name of either Images_Asia, Images_Eur, orImages_SAmer.
None of the above.
All of the following are valid remarks about converting other file types to an IBM EXCEPT which ONE?
The transformation rules are highly configurable.
After the conversion is complete the form Designer must tweak the layout before publishing the final version.
After the conversion is complete the form Designer must add dynamic logic to the forms.
The transformation rules are not configurable.
Which of the following reasons for compressing an IBM Form is VALID?
Compressing the form means that the contents of the form are encrypted and secure.
Compressing the form means that the entire form and data model be stored as a single file.
Compressing the form means you can post the form to a database or servlet.
Compressing the form means that you eliminate the white space found in the XFDL file.
All of the following are accessibility features of the Viewer or Webform Server EXCEPT which one?
Can define text to be spoken by a narration tool.
Can enable a focus indicator
Can change the background color of the focused item
Can enable high contrast mode
Which absolute XPath query will properly limit the result set to 10 items?

The web Is damaged | A2040-403 Real Questions and VCE Practice Test
In his workplace in the gleaming-stainless-metal and orange-brick jumble of MIT’s Stata core, cyber web elder statesman and onetime chief protocol architect David D. Clark prints out an historic PowerPoint speak. Dated July 1992, it tiers over technical considerations like domain naming and scalability. however in a single slide, Clark points to the cyber web’s darkish aspect: its lack of built-in safety.
In others, he observes that from time to time the worst disasters are led to now not via unexpected routine but with the aid of slow, incremental processes – and that humans are first rate at ignoring complications. “issues worsen slowly. people alter,” Clark referred to in his presentation. “The difficulty is assigning the correct diploma of fear to distant elephants.”
today, Clark believes the elephants are upon us. sure, the web has wrought wonders: e-commerce has flourished, and email has turn into a ubiquitous capacity of communication. almost a thousand million individuals now use the internet, and important industries like banking increasingly depend on it.
at the equal time, the internet’s shortcomings have resulted in plunging security and a lowered capacity to accommodate new technologies. “we're at an inflection aspect, a revolution point,” Clark now argues. And he delivers a strikingly pessimistic evaluation of where the web will come to be without dramatic intervention. “We might just be at the element where the utility of the web stalls – and perhaps turns downward.”
indeed, for the general user, the web at the present time all too often resembles big apple’s times rectangular within the Nineteen Eighties. It turned into entertaining and vibrant, however you made sure to hold your head down, lest you be provided medicine, robbed, or harangued via the insane. times rectangular has been cleaned up, however the internet continues getting worse, each at the consumer’s level, and – within the view of Clark and others – deep inside its structure.
through the years, as web purposes proliferated – wireless contraptions, peer-to-peer file-sharing, telephony – companies and network engineers came up with ingenious and expedient patches, plugs, and workarounds. The result is that the initially essential communications expertise has become a posh and convoluted affair. For all the information superhighway’s wonders, it is additionally problematic to manipulate and extra fragile with each passing day.
That’s why Clark argues that it’s time to rethink the information superhighway’s fundamental architecture, to doubtlessly beginning over with a clean design – and equally essential, with a believable strategy for proving the design’s viability, so that it stands an opportunity of implementation. “It’s now not as if there is some killer technology on the protocol or community level that we by hook or by crook failed to encompass,” says Clark. “We deserve to take the entire applied sciences we already know and fit them together in order that we get a different standard device. this is now not about constructing a expertise innovation that alterations the realm but about structure – pulling the items collectively in a different technique to achieve excessive-stage pursuits.”
just such an strategy is now gaining momentum, spurred on by the national Science basis. NSF managers are working to forge a 5-to-seven-year plan estimated to can charge $200 million to $300 million in analysis funding to boost clear-slate architectures that provide safety, accommodate new technologies, and are less complicated to manipulate.
They also hope to improve an infrastructure that may also be used to prove that the brand new device is actually enhanced than the latest one. “If we prevail in what we are attempting to do, here's greater than anything else we, as a research neighborhood, have accomplished in desktop science thus far,” says Guru Parulkar, an NSF application supervisor worried with the effort. “when it comes to its mission and vision, it's a extremely massive deal. but now we are just at the beginning. It has the knowledge to trade the game. It may take it to the subsequent level in realizing what the information superhighway may be that has not been viable because of the challenges and issues.”
Firewall NationWhen AOL updates its software, the new edition bears a number: 7.0, 8.0, 9.0. the most fresh edition is referred to as AOL 9.0 security edition. nowadays, enhancing the utility of the cyber web is not so lots about delivering the newest cool application; it’s about survival.
In August, IBM launched a examine reporting that “virus-laden e-mails and crook pushed protection attacks” leapt by 50 % within the first half of 2005, with executive and the financial-capabilities, manufacturing, and health-care industries within the crosshairs. In July, the Pew cyber web and American life task suggested that forty three percent of U.S. information superhighway clients – fifty nine million adults – said having adware or spy ware on their computer systems, thanks in basic terms to traveling sites. (in lots of instances, they learned this from the unexpected proliferation of error messages or freeze-ups.) utterly 91 % had adopted some shielding conduct – keeping off definite forms of sites, say, or no longer downloading application. “Go to a neighborhood bar, and people are speaking about firewalls. That changed into just no longer proper three years ago,” says Susannah Fox, associate director of the Pew task.
Then there's spam. One main online safety company, Symantec, says that between July 1 and December 31, 2004, spam surged 77 p.c at corporations that Symantec monitored. The raw numbers are miraculous: weekly spam totals on average rose from 800 million to greater than 1.2 billion messages, and 60 % of all electronic mail become spam, in keeping with Symantec.
but perhaps most menacing of all are “botnets” – collections of computer systems hijacked by way of hackers to do far flung-manage projects like sending junk mail or attacking web sites. This variety of wholesale hijacking – made stronger with the aid of huge adoption of at all times-on broadband connections – has spawned tough-core crime: digital extortion. Hackers are threatening harmful attacks in opposition t corporations that don’t meet their financial demands. according to a study by way of a Carnegie Mellon school researcher, 17 of one hundred corporations surveyed had been threatened with such attacks.
with ease put, the internet has no inherent security architecture – nothing to cease viruses or junk mail or anything else. Protections like firewalls and antispam utility are add-ons, protection patches in a digital arms race.
The President’s assistance know-how Advisory Committee, a group stocked with a who’s who of infotech CEOs and educational researchers, says the condition is bad and getting worse. “these days, the threat evidently is turning out to be,” the council wrote in a file issued in early 2005. “Most warning signs and studies of the frequency, have an impact on, scope, and value of cyber safety incidents – amongst both companies and individuals – point to always expanding degrees and varieties of attacks.”
And we haven’t even considered a real act of cyberterror, the “digital Pearl Harbor” memorably expected by former White apartment counterterrorism czar Richard Clarke in 2000 (see “A Tangle of Wires”). agree with the nation’s electrical grid: it relies on continual community-based communications between energy flowers and grid managers to retain a stability between creation and demand. A neatly-positioned assault may trigger a costly blackout that might cripple part of the nation.
The conclusion of the advisory council’s document couldn't have been starker: “The IT infrastructure is particularly prone to premeditated attacks with doubtlessly catastrophic consequences.”
The equipment capabilities as neatly as it does only because of “the forbearance of the virus authors themselves,” says Jonathan Zittrain, who cofounded the Berkman center for web and Society at Harvard law faculty and holds the Chair in information superhighway Governance and regulation at the university of Oxford. “With one or two additional lines of code…the viruses may wipe their hosts’ complicated drives clean or quietly insinuate false records into spreadsheets or files. Take any of the properly ten viruses and add a bit of poison to them, and many of the world wakes up on a Tuesday morning unable to surf the net – or discovering lots less there if it could.”
Patchwork ProblemThe information superhighway’s original protocols, forged in the late Sixties, have been designed to do one element very well: facilitate communique between a couple of hundred tutorial and govt users. The protocols effectively destroy digital records into simple instruments referred to as packets and ship the packets to their locations via a collection of community routers. both the routers and PCs, often known as nodes, have wonderful digital addresses referred to as web Protocol or IP addresses. That’s basically it. The system assumed that each one clients on the network could be trusted and that the computers linked by the web were generally fastened objects.
The information superhighway’s design turned into detached to whether the counsel packets brought as much as a malicious virus or a love letter; it had no provisions for doing lots besides getting the data to its destination. Nor did it accommodate nodes that moved – corresponding to PDAs that might connect with the internet at any of myriad locations. over the years, a slew of patches arose: firewalls, antivirus application, spam filters, and the like. One patch assigns each and every cell node a brand new IP address anytime it moves to a brand new element in the community.
[Click here to view graphic representations of David D. Clark’s four goals for a new Internet architecture.]
certainly, protection patches aren’t maintaining pace. That’s partly as a result of distinct individuals use diverse patches and not each person updates them religiously; some individuals don’t have any put in. And the most normal mobility patch – the IP addresses that continuously exchange as you stream around – has downsides. When your mobile computing device has a brand new identification each time it connects to the cyber web, the web sites you cope with continually won’t are aware of it’s you. This potential, for instance, that your favourite airline’s internet web page might not cough up a reservation form along with your name and typical-flyer quantity already stuffed out. The normally altering address additionally skill that you may expect breaks in carrier when you are the usage of the cyber web to, say, take heed to a streaming radio broadcast in your PDA. It additionally capability that someone who commits against the law on-line the usage of a cell device may be more
durable to track down.
in the view of many specialists within the container, there are even more primary reasons to be concerned. Patches create an ever more advanced device, one which becomes tougher to control, have in mind, and improve upon. “We’ve been on a tune for 30 years of incrementally making advancements to the internet and fixing issues that we see,” says Larry Peterson, a laptop scientist at Princeton school. “We see vulnerability, we are trying to patch it. That approach is one which has labored for 30 years. however there's cause to be concerned. with out a protracted-time period plan, in case you are only patching the subsequent issue you see, you become with an increasingly complicated and brittle equipment. It makes new capabilities difficult to employ. It makes it a good deal harder to manipulate because of the delivered complexity of all these point options which have been added. on the same time, there is situation that we'll hit a dead conclusion at some point. There will be complications we
are able to’t sufficiently patch.”
The patchwork method draws complaints even from the founding father of a business it truly is essentially an intricate and ingenious patch for one of the vital web’s shortcomings. Tom Leighton is cofounder and chief scientist of Akamai, an organization that ensures that its clients’ net pages and purposes are all the time attainable, even though large numbers of valued clientele are attempting to log on to them or a key fiber-optic cable is severed. Akamai intently monitors community complications, strategically stores copies of a client’s site at servers world wide, and accesses those servers as essential. however while his enterprise makes its funds from patching the web, Leighton says the whole gadget needs simple architectural exchange. “we're in the mode of trying to plug holes in the dike,” says Leighton, an MIT mathematician who's also a member of the President’s tips expertise Advisory Committee and chair of its Cyber protection Subcommittee. “There are further and further
holes, and extra substances are going to plugging the holes, and there are much less materials being dedicated to basically changing the game, to changing the internet.”
When Leighton says “supplies,” he’s speakme about billions of greenbacks. Take Microsoft, for example. Its utility mediates between the information superhighway and the computing device. nowadays, of the $6 billion that Microsoft spends annually on analysis and building, approximately one-third, or $2 billion, is directly spent on safety efforts. “The evolution of the internet, the construction of threats from the web that could try to interfere on methods – even if net servers, net browsers, or e-mail-based mostly threats – in fact changed the equation,” says Steve Lipner, Microsoft’s director of protection method and engineering method. “Ten years ago, I feel americans right here in the trade were designing utility for brand new elements, new efficiency, ease of use, what have you ever. these days, we instruct each person for security.” not most effective does this center of attention on protection siphon materials from different research, however it can even bog down research
that does get funded. Some innovations have been kept within the lab, Lipner says, because Microsoft couldn’t make sure they met protection requirements.
Of path, some would argue that Microsoft is now scrambling to make up for years of selling insecure products. but the Microsoft example has parallels in other places. Eric Brewer, director of Intel’s Berkeley, CA, research lab, notes that expenses on safety are like a “tax” and are “costing the nation billions and billions of dollars.” This tax shows up as extended product fees, as agencies’ bills on security capabilities and harm fix, as the portion of processor pace and storage committed to operating defensive classes, because the network capability consumed by using unsolicited mail, and because the prices to the common person trying to dodge the online minefield of purchasing the latest firewalls. “We fully can leave issues by myself. but it surely has this continual 30 percent tax, and the tax may go up,” Brewer says. “The penalty for no longer [fixing] it isn’t immediately deadly. however things will slowly get worse and may get so bad that americans won’t use the
information superhighway as lots as they may like.”
The current information superhighway architecture additionally stands in the method of new applied sciences. Networks of clever sensors that jointly display screen and interpret things like manufacturing facility circumstances, the weather, or video images might trade computing as an awful lot as low cost PCs did twenty years ago. however they've totally diverse communique requirements. “Future networks aren’t going to be PCs docking to mainframes. It’s going to be about some vehicle contacting the motor vehicle next to it. All of here is going on in an embedded context. every thing is computer to laptop as opposed to individuals to americans,” says Dipankar Raychaudhuri, director of the wireless suggestions network Laboratory (Winlab) at Rutgers tuition. With nowadays’s structure, making such a imaginative and prescient fact would require further and further patches.
Architectural DigestWhen Clark talks about developing a new architecture, he says the job have to start with the environment of dreams. First, provide the medium a basic security architecture – the skill to authenticate whom you're speaking with and forestall issues like junk mail and viruses from ever achieving your computer. stronger protection is “essentially the most critical motivation for this redecorate,” Clark says. 2d, make the brand new structure purposeful with the aid of devising protocols that permit information superhighway carrier providers to better route traffic and collaborate to offer superior services with out compromising their organizations. Third, enable future computing contraptions of any size to connect to the internet – now not simply PCs however sensors and embedded processors. Fourth, add know-how that makes the community less demanding to manipulate and more resilient. for example, a new design may still allow all items of the network to realize and report
emerging issues – no matter if technical breakdowns, site visitors jams, or replicating worms – to community directors.
The decent news is that some of those desires aren't thus far off. NSF has, over the past few years, spent more than $30 million helping and planning such analysis. academic and corporate analysis labs have generated a couple of promising applied sciences: ways to authenticate who’s online; methods to determine criminals whereas maintaining the privacy of others; the right way to add instant instruments and sensors. while no one is announcing that any single one of these applied sciences may be included in a new architecture, they provide a place to begin for knowing what a “new” web may in reality seem like and the way it would vary from the ancient one.
Some promising technologies that may determine into this new architecture are coming from PlanetLab, which Princeton’s Peterson has been nurturing in contemporary years (see “The web Reborn,” October 2003). in this nonetheless-starting to be assignment, researchers during the area were constructing software that can be grafted onto nowadays’s dumb cyber web routers. One illustration is utility that “sniffs” passing information superhighway traffic for worms. The application looks for telltale packets sent out by worm-infected machines attempting to find new hosts and may warn equipment administrators of infections. other application prototypes notice the emergence of information site visitors jams and are available up with extra productive ways to reroute site visitors around them. These styles of algorithms could turn into part of a fundamental new infrastructure, Peterson says.
A 2d set of technologies could aid authenticate internet communications. it will be a huge boon to internet security if you could make certain an email out of your financial institution is truly from your bank and not a scam artist, and if the bank might make certain that after a person logs in to your account, that grownup is basically you and never a person who stole your account quantity.
nowadays, the onus of authentication is on the information superhighway person, who is consistently requested to latest tips of quite a lot of kinds: passwords, social-protection numbers, worker identity numbers, credit card numbers, regular-flyer numbers, PIN numbers, and so on. however when thousands and thousands of users are consistently coming into these gate-opening numbers, it makes it that a great deal simpler for spyware, or a thief sniffing wireless internet site visitors, to steal, commit fraud, and do hurt.
One evolving solution, developed with the aid of Internet2 – a research consortium based mostly in Ann Arbor, MI, that develops advanced web technologies to be used by using analysis laboratories and universities – effortlessly creates a middleman who does the job. known as Shibboleth, the utility mediates between a sender and a recipient; it transmits the applicable identification numbers, passwords, and different identifying suggestions to the right recipients for you, securely, through the centralized change of digital certificates and other potential. moreover making the dispersal of suggestions greater secure, it helps give protection to privateness. That’s since it discloses best the “attributes” of someone pertinent to a particular transaction, instead of the grownup’s full “identification.”
at this time, Shibboleth is used through universities to mediate entry to online libraries and different supplies; in case you go browsing, the college knows your “attribute” – you're an enrolled student – and not your name or other personal suggestions. This primary idea can be accelerated: your employment popularity may open the gates to your company’s servers; your birth date could help you buy wine online. a similar scheme might give a financial institution self assurance that online account access is respectable and conversely provide a bank consumer self belief that banking communications are definitely from the financial institution.
Shibboleth and an identical applied sciences in building can, and do, work as patches. however some of their simple features could also be constructed right into a substitute information superhighway architecture. “Most individuals appear on the internet as any such dominant drive, they best think how they can make it a bit greater,” Clark says. “I’m asserting, ‘hi there, feel concerning the future otherwise. What may still our communications environment of 10 to fifteen years from now seem like? what is your goal?’”
The satan We KnowIt’s worth remembering that regardless of all of its flaws, all of its architectural kluginess and insecurity and the fees linked to patching it, the information superhighway nevertheless gets the job executed. Any effort to put in force a more robust version faces enormous useful problems: all information superhighway provider providers would have to comply with alternate all their routers and application, and someone would must foot the invoice, that allows you to probably come to many billions of greenbacks. but NSF isn’t proposing to desert the ancient community or to forcibly impose anything new on the realm. somewhat, it well-nigh desires to build an improved mousetrap, reveal that it’s greater, and permit a changeover to take vicinity based on user demand.
To that conclusion, the NSF effort envisions the building of a sprawling infrastructure that could cost about $300 million. it will consist of research labs throughout the united states and maybe hyperlink with analysis efforts overseas, the place new architectures will also be given a full workout. With a high-pace optical backbone and smart routers, this examine mattress can be far more complex and representative than the smaller, greater constrained examine beds in use today. The idea is that new architectures could be battle verified with true-world information superhighway traffic. “You hope that offers ample cost delivered that americans are slowly and selectively inclined to change, and maybe it receives enough traction that americans will change over,” Parulkar says. however he acknowledges, “Ten years from now, how issues play out is any person’s wager. It generally is a parallel infrastructure that americans may use for selective applications.”

nevertheless, skeptics declare that a wiser community may well be much more complex and for that reason failure-prone than the normal naked-bones information superhighway. ordinary wisdom holds that the community may still continue to be dumb, however that the wise instruments at its ends should turn into smarter. “I’m now not satisfied with the present scenario. I’m not happy with unsolicited mail; I’m no longer chuffed with the quantity of vulnerability to quite a lot of styles of attack,” says Vinton Cerf, probably the most inventors of the web’s basic protocols, who lately joined Google with a job title created only for him: chief web evangelist. “I do want to distinguish that the primary vectors causing loads of problem are penetrating holes in working programs. It’s greater just like the working programs don’t protect themselves very smartly. An argument can be made, ‘Why does the network must try this?’”
according to Cerf, the greater you ask the network to assess information – to authenticate someone’s identity, say, or look for viruses – the much less effectively it is going to stream the statistics round. “It’s really tough to have a community-stage issue do that stuff, which capability you must assemble the packets into anything larger and hence violate all the protocols,” Cerf says. “That takes a heck of lots of components.” still, Cerf sees price in the new NSF initiative. “If Dave Clark…sees some notions and ideas that might be dramatically more desirable than what we've, I feel that’s critical and match,” Cerf says. “I sort of ask yourself about whatever, even though. The cave in of the web, or an enormous protection catastrophe, has been envisioned for a decade now.” and naturally no such catastrophe has occurred – at the least now not by the point this subject of technology overview went to press.
The NSF effort to make the medium smarter additionally runs up in opposition t the libertarian tradition of the cyber web, says Harvard’s Zittrain. “The NSF application is a useful one in the first example since it begins with the premise that the current internet has outgrown a few of its initial foundations and linked tenets,” Zittrain says. “however there is a possibility, too, that any try and rewrite the web’s technical constitution could be so plenty more fraught, so tons extra self-aware of the nontechnical concerns at stake, that the treatment can be worse than the problem.”
nevertheless, Zittrain sees hazards forward if some sensible motion isn’t taken. He posits that the internet’s protection problems, and the theft of intellectual property, may produce a counterreaction that might volume to a clampdown on the medium – every thing from the tightening of application makers’ control over their working methods to protection lockdowns through businesses. and of course, if a “digital Pearl Harbor” does occur, the federal executive is vulnerable to respond reflexively with heavy-passed reforms and controls. If such tightenings happen, Zittrain believes we’re bound to get an internet that is, in his words, “extra at ease – and less exciting.”
however what each side agree on is that the information superhighway’s perennial complications are getting worse, at the identical time that society’s dependence on it's deepening. just just a few years in the past, the work of researchers like Peterson didn’t garner vast activity outside the networking community. however at the moment, Clark and Peterson are giving briefings to Washington policymakers. “there's cognizance that some of those issues are probably rather serious. You might argue that they have always been there,” Peterson says. “but there is a much broader consciousness within the optimum stage of the executive that this is authentic. We are becoming to the factor where we are briefing americans within the president’s office of Science and know-how coverage. I notably did, and other individuals are doing that as well. as far as i do know, that’s fairly new.”
outside the door to Clark’s office at MIT, a nametag positioned by using a prankster colleague proclaims it to be the workplace of Albus Dumbledore – the sensible headmaster of the Hogwarts school of Witchcraft and Wizardry, a principal figure in the Harry Potter books. however whereas Clark in past years can also have wrought some magic, assisting radically change the customary information superhighway protocols into a sturdy communications technology that changed the realm, he no longer has tons control over what happens subsequent.
but “because we don’t have vigour, there's a improved opportunity that we could be left on my own to are trying,” he says. And so Clark, like Dumbledore, clucks over new generations of technical wizards. “My aim in calling for a fresh design is to free our minds from the latest constraints, in an effort to envision a distinct future,” he says. “The intent I stress here is that the cyber web is so large, and so successful, that it seems like a idiot’s errand to ship a person off to invent a different one.” whether the culmination is a whole new architecture – or simply an exceptional set of adjustments to the current one – may also no longer remember in the conclusion. Given how entrenched the web is, the effort will have succeeded, he says, if it at the least gets the analysis community working towards average desires, and helps “impose creep within the correct direction.”
