Question #3 Section 2
What are two advantages of YANG-based approaches for infrastructure automation? (Choose two.)
multi-platform vendor abstraction
compiles to executables that run on network devices
designed to reflect networking concepts
command line driven interface
Which device is used to transport traffic from one broadcast domain to another broadcast domain?
layer 2 switch
Question #5 Section 2
Which service provides a directory lookup for IP addresses and host names?
Question #6 Section 2
Users cannot access a webserver and after the traffic is captured, the capture tool shows an ICMP packet that reports "time exceeded in-transit". What is the cause of this webserver access issue?
A router along the path has the wrong time.
A router along the path is misrouting the packets in a wrong direction.
The server is too loaded and the connection could not be handled in time.
The server is too far away and the packets require too much time to reach it.
Question #7 Section 2
What is used in Layer 2 switches to direct packet transmission to the intended recipient?
Question #8 Section 2
FILL BLANK -
Fill in the blanks to complete the Bash script in which each file in a directory is renamed to its SHA256 hash?
for f in ' '; do
$f' openssl sha -sha256 -r < $f | cut -f1 -cl' ''
echo $f' openssl sha -sha256 -r < $f | cut -f1 -cl' ''
Question #9 Section 2
Users cannot access a webserver and after the traffic is captured, the capture tool shows an ICMP packet that reports "communication administratively prohibited". What is the cause of this webserver access issue?
An access list along the path is blocking the traffic.
Users must authenticate on the webserver to access it.
A router along the path is overloaded and thus dropping traffic.
The traffic is not allowed to be translated with NAT and dropped.
Question #10 Section 2
What is an advantage of a version control system?
facilitates resolving conflicts when merging code
ensures that unit tests are written
prevents over-writing code or configuration files
forces the practice of trunk-based development
Question #11 Section 2
A 401 HTTP response code is returned when calling a REST API. What is the error state identified by this response code?
The server cannot process the request as it has detected an issue in the request syntax or body.
The request has not been accepted because it requires authentication.
The sever accepted the request but the client is not authorized for this content.
The server cannot find the requested resource because the path specified is incorrect.
Question #12 Section 2
What is the first development task in test-driven development?
Write code that implements a desired function.
Write a failing test case for a desired function.
Reverse engineer the code for a desired function.
Write a passing test case for existing code.
Question #13 Section 2
What is the purpose of a firewall in application deployment?
adds TLS support to an application that does not support it natively
limits traffic to only ports required by the application
provides translation for an application's hostname to its IP address
forwards traffic to a pool of instances of the application
Question #14 Section 2
A small company has 5 servers and 50 clients. What are two reasons an engineer should split this network into separate client and server subnets? (Choose two.)
Subnets will split domains to limit failures.
A router will limit the traffic types between the clients and servers.
Subnets provide more IP address space for clients and servers.
A router will bridge the traffic between clients and servers.
Internet access to the servers will be denied on the router.
Question #15 Section 2
How does a developer create and switch to a new branch called "my-bug-fix" to develop a product fix?
git checkout -b my-bug-fix
git branch -b my-bug-fix
git branch my-bug-fix
git checkout my-bug-fix
Question #16 Section 2
What operation is performed with YANG model-driven programmability in NX-OS?
configure a device with native and OpenConfig-based models
bootstrap a device that has a factory-default configuration
send CLI commands to a device and retrieve output in JSON format
run Linux commands natively on the device
