Which of the following is NOT a good use case for the volume backup feature of the Oracle Cloud Infrastructure Block Volume service?

• A. Rapidly duplicate an environment in seconds to test configuration changes without impacting your production environment.
• B. Meet compliance and regulatory requirements for data to remain unchanged over time, so that it can be retrieved for audit purposes.
• C. Retain a copy of data in a volume, so that you can duplicate an environment later or preserve the data for future use.
• D. Support business continuity requirements of reducing the risk of outages or data mutation over time.

A developer is using Oracle Functions to deploy her code as part of an event-driven solution in Oracle Cloud Infrastructure (OCI). When she invokes her function, Oracle Functions returns a FunctionlnvokelmageNotAvailable message and a 502 error:

Which of the following options is NOT a plausible reason for this error?

• A. OCI Events service rule is not configured with the correct location of the function in OCI Registry.
• B. The function does not exist in the specified location in OCI Registry.
• C. Missing or invalid IAM policy to give Oracle Functions read access to images stored for functions in repositories in OCI Registry.
• D. The VCN being used does not have an internet gateway or a service gateway configured for Oracle Functions to be able to access OCI Registry.

You are trying to delete a compartment. The delete operation is falling and you need to troubleshoot the problem.
Which step should NOT be considered when troubleshooting this issue?

• A. Make sure you have at least one more compartment in your tenancy other than the root compartment.
• B. Verify that there are no policies In the root compartment that reference the compartment you are trying to delete.
• C. Search for resources in the compartment for each region that your tenancy is subscribed to.
• D. Verify that you have removed all resources from the compartment.

An online registration system Is currently hosted on one large Oracle Cloud Infrastructure (OCT) Bare metal compute Instance with attached block volume to store of the users' dat a. The registration system accepts the Information from the user, Including documents and photos then performs automated verification and processing to check it the user is eligible for registration.
The registration system becomes unavailable at tunes when there is a surge of users using the system the existing architecture needs improvement as it takes a long time for the system to complete the processing and the attached block volumes are not large enough to use data being uploaded by the users.
Which Is the most effective option to achieve a highly scalable solution?

• A. Change your architecture to use an OCI Object Storage standard tier bucket, replace the single bare metal instance with a Oracle Streaming Service (OSS) to ingest the Incoming requests and distribute the tasks to a group of compute Instances with Auto Scaling
• B. Attach more Block volumes as the data volume increase, use Oracle Notification Service (ONS) to distribute tasks to a pool of compute instances working In parallel, and Auto Scaling to dynamically size the pool of Instances depending on the number of notifications received from the Notification Service. Use Resource Manager stacks to replicate your architecture to another region.
• C. Upgrade your architecture to use more Block volumes as the data volume Increases. Replace the single bare metal instance with a group of compute instances with Auto Scaling to dynamically increase or decrease the compute instance pools depending on the traffic.
• D. Upgrade your architecture to use a pool of Bare metal servers and configure them to use their local SSDs for faster data access Set up Oracle Streaming Service (OSS) to distribute the tasks to the pool of Bare metal Instances with Auto Scaling to dynamically increase or decrease the pool of compute instances depending on the length of the Streaming queue.

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.)

• A. 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.
• B. 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.
• C. 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.
• D. 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.
