Question #44 Section 1
You are tasked with building a highly available, fault tolerant web application for your current employer. The security team is concerned about an increase in malicious web-based attacks across the internet and asked what you can do to add a higher level of security to the website.
How should you architect the solution on Oracle Cloud Infrastructure (OCI) to meet all requirements defined by your organization? (Choose the best answer.)
Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Deploy a Web Application Firewall (WAF) and configure the load balancer public IP address as the origin.
Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Create a Geolocation steering policy in Traffic Management and add an answer pool that directs to the public IP address of the load balancer. Configure a global catch-all rule to use this answer pool.
Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Ensure that each web application server is assigned a public IP address. Deploy a Web Application Firewall (WAF) and configure one Origin for each public IP address.
Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Use the OCI Traffic Management service to create a load balancing policy that will resolve DNS evenly between all web servers.
Question #45 Section 1
Given this compartment structure:
You are managing a compute instance that currently resides in the Compute compartment. The Virtual Cloud Network (VCN) into which the compute instance was originally deployed, also resides in this compartment. To support a project-related task, you need to move just the compute instance to the SysTest-Team compartment. You log into your Oracle Cloud Infrastructure (OCI) account and use the Move Resource option to place the compute instance in the new compartment.
What will be the result of your attempt to move the compute instance to the new compartment? (Choose the best answer.)
The move will be successful. The compute instance's public and private IP addresses will stay the same. The compute instance will remain associated with the VCN from the source compartment.
The move will fail and you will be prompted to move the VCN first. Once VCN is moved to the target compartment, the compute instance can be moved.
After moving the compute instance, you must move the compute instance VNIC as a separate action. The public and private IP addresses of the instance will remain unchanged and it will still be associated with the VCN from the source compartment.
The move will be successful. However, the compute instance's public and private IP addresses will change, and it will be associated to the first VCN that was created in the new, target compartment.
Question #46 Section 1
A civil engineering company is running an online portal in which engineers can upload their constructions photos, videos, and other digital files.
There is a new requirement for you to implement: the online portal must offload the digital content to an Object Storage bucket for a period of 72 hours. After the provided time limit has elapsed, the portal will hold all the digital content locally and wait for the next offload period.
Which option fulfills this requirement? (Choose the best answer.)
Create a pre-authenticated URL for the entire Object Storage bucket to read and list the content with an expiration of 72 hours.
Create a Dynamic Group with matching rule for the portal compute instance and grant access to the Object Storage bucket for 72 hours.
Create a pre-authenticated URL for the entire Object Storage bucket to write content with an expiration of 72 hours.
Create a pre-authenticated URL for each object that is uploaded to the Object Storage bucket with an expiration of 72 hours.
Question #47 Section 1
To serve web traffic for a popular product, your cloud engineer has provisioned four BM.Standard2.52 instances, evenly spread across two availability domains in the us-ashburn-1 region; LoadBalancer is used to deliver the traffic across instances.
After several months, the product grows even more popular and you need additional compute capacity. As a result, an engineer provisioned two additional
You register the two VM.Standard2.8 instances with your Load Balancer Backend set and quickly find that the VM.Standard2.8 instances are now running at
100% of CPU utilization but the BM.Standard2.52 instances have significant CPU capacity that's unused. Which option is the most cost effective and uses instances capacity most effectively? (Choose the best answer.)
Configure Autoscaling instance pool with LoadBalancer to add up to 3 more BM.Standard2.52 instances when triggered. Shut off VM.Standard2.8 instances.
Configure LoadBalancer with two VM.Standard2.8 instances and use Autoscaling instance pool to add up to two additional VM.Standard2.8 instances. Shut off BM.Standard2.52 instances.
Route traffic to BM.Standard2.52 and VM.Standard2.8 instances directly using DNS and Health Checks. Shut off the Load Balancer.
Configure your Load Balancer with weighted round robin policy to distribute traffic to the compute instances, with more weight assigned to bare metal instances.
Question #48 Section 1
A large financial company has a web application hosted in their on-premises data center. They are migrating their application to Oracle Cloud Infrastructure (OCI) and require no downtime while the migration is on-going. In order to achieve this, they have decided to divert only 30% of the traffic to the new application running in OCI and keep the rest 70% traffic to their on-premises infrastructure. Once the migration is complete and application works fine, they will divert all traffic to OCI.
As a solution architect working with this customer, which suggestion should you provide them? (Choose the best answer.)
Use OCI Traffic management with Failover steering policy and distribute the traffic between OCI and on-premises infrastructure.
Use an OCI Load Balancer and distribute the traffic between OCI and on-premises infrastructure.
Use VPN connectivity between on-premises infrastructure and OCI, and create routing tables to distribute the traffic between them.
Use OCI Traffic management with Load Balancing steering policy and distribute the traffic between OCI and on-premises infrastructure.
Question #49 Section 1
Your company developed a function that needs to access the Oracle Database to inject some data to it at runtime. You are tasked to move this function to the
Oracle Cloud Infrastructure (OCI) and use Oracle Functions and access Oracle Autonomous Database. You created a Dockerfile below to run this function, however, you are getting this error "cx_Oracle.DatabaseError: ORA""12560: TNS:protocol adapter error".
What should you do to make sure that Oracle Functions can run this Dockerfile properly? (Choose the best answer.)
Add these two lines to your Dockerfile: groupadd """"gid 1000 fn && \ adduser """"uid 1000 """"gid fn fn
Use """"privileged flag while running the Docker container to add runtime privilege
Use """"cap""add=ALL flag while running the Docker container to add runtime capability
You ned to run this Container as root, so add this line: USER root
Question #50 Section 1
Your company needs to migrate a business critical application from your data center to Oracle Cloud Infrastructure (OCI). The application runs on Oracle
Database and both the application and database servers run on Oracle Linux version 7. The application server is WebLogic server running on multiple 4- core servers and the database is deployed as an Oracle Database Enterprise Edition RAC database on 2 servers (4-cores each).
Which method of database migration should you choose so that the application has minimal impact? (Choose the best answer.)
Deploy Virtual Machine RAC DB system on OCI and use the Oracle Database Backup module with RMAN to migrate the data from customer on-premises to OCI.
Deploy Virtual Machine RAC DB system on OCI and use the ZDM tool for the database migration.
Deploy Autonomous Transaction Processing Database on OCI and use the MV2ADB tool for the database migration.
Deploy Exadata Cloud Service Base rack and use Oracle Data Pump tool to migrate the data from customer on-premises to OCI.
