You have a Linux compute instance located in a public subnet in a VCN which hosts a web application. The security list attached to subnet containing the compute instance has the following stateful ingress rule.

The Route table attached to the Public subnet is shown below.You can establish an SSH connection into the compute instance from the internet. However, you are not able to connect to the web server using your web browser.

Which step will resolve the issue? (Choose the best answer.)

• A. In the route table, add a rule for your default traffic to be routed to NAT gateway.
• B. In the security list, remove the ssh rule.
• C. In the route table, add a rule for your default traffic to be routed to service gateway.
• D. In the security list, add an ingress rule for port 80 (http).

You have been asked to update the lifecycle policy for object storage using the Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI). Which command can successful-ly update the policy? (Choose the best answer.)

• A. oci os object-lifecycle-policy put --ns <object_storage_namespace> --bn <bucket_name> -- --items
  <json_formatted_lifecycle_policy>
• B. oci os object-lifecycle-policy get --ns <object_storage_namespace> --bn <bucket_name>
• C. oci os object-lifecycle-policy put --ns <object_storage_namespace> --bn <bucket_name>
• D. oci os object-lifecycle-policy delete --ns <object_storage_namespace> --bn <buck-et_name>

You have created several block volumes in the us-phoenix-1 region in a specific compart-ment. The compartment can be identified by the following Oracle Cloud Infrastructure (OCI) unique identifier, or ocid1.compartment.oc1.phx..exampleuniquelD Your manager has asked you to leverage the OCI monitoring service and write a metric query showing all read IOPS at a one-minute interval, filtered to this compartment and aggregated for the maximum. Which metric query will you create?

• A. IopsRead[lm]{compartmentId='ocldl.compartment.ocl.phx..exampleuniquelD'}.max()
• B. Iop-sWrite[lm]{compartmentId=Hocidl.compartment.ocl.phx..exampleuniquelD'}.mean()
• C. Iop-sRead[lm{compartmentId='ocidl.compartment.ocl.phx..exampleuniquelD'}.grouplng().max()
• D. IopsRead[lm]{compartmentId = 'odd1.compartment.ocl.phx..exampleuniquelD'}.grouping().mean()

Which two statements about the Oracle Cloud Infrastructure (OCI) Command Line Inter-face (CLI) are TRUE? (Choose two.)

• A. The CLI allows you to use the Python language to interact with OCI APIs.
• B. You can filter CLI output using the JMESPath query option for JSON.
• C. The CLI provides an automatic way to connect with instances provisioned on OCI.
• D. You can run CLI commands from inside OCI Regions only.
• E. The CLI provides the same core functionality as the Console, plus additional commands.

Recently, your e-commerce web application has been receiving significantly more traffic than usual. Users are reporting they often encounter a 503 Service Error when trying to access your site. Sometimes the site is very slow. You check your instance pool configuration to con-firm that the maximum number of instances is configured toallow 20 compute instances. Currently, 14 compute instances have been provisioned by the instance pool. You also confirm that current CPU utilization across all hosts exceeds the scale-out threshold you set in your auto-scaling policy. However, the instance pool is not provisioning any new instances. What can you check to determine why the application is NOT functioning properly? (Choosethe best answer.)

• A. Verify that the Quality Assurance team is not currently performing load-testing against production.
• B. Verify that the new offer feature code did not introduce any performance bugs.
• C. Verify that the compute resource quota has not been exceeded.
• D. Verify that the database is accessible.
