Here is a partial code from a Terraform template written for Oracle Cloud Infrastructure (OCI):

What operation(s) does it perform? (Choose the best answer.)

• A. Creates a lifecycle policy for an OCI Object Storage bucket for moving data to Archival storage at a specified time.
• B. Provides object read and write access for an OCI Object Storage bucket.
• C. Creates a pre-authenticated request for objects in an OCI Object Storage bucket.
• D. Creates a URL to provide access to an OCI Object Storage bucket for managing objects.

Multiple teams are sharing a tenancy in Oracle Cloud Infrastructure (OCI). You are asked to figure out an appropriate method to manage OCI costs.
Which is NOT a valid technique to accurately attribute costs to resources used by each team? (Choose the best answer.)

• A. Create separate compartment for each team. Use the OCI cost analysis tools to filter costs by compartment.
• B. Create an Identity and Access Management (IAM) group for each team. Create an OCI budget for each group to track spending.
• C. Define and use tags for resources used by each team. Analyze usage data from the OCI Usage Report which has detailed information about resources and tags.
• D. Create a Cost-Tracking tag. Apply this tag to all resources with team information. Use the OCI cost analysis tools to filter costs by tags.

Your application is using an Object Storage bucket named app-data in the namespace vision, to store both persistent and temporary dat a. Every week all the temporary data should be deleted to limit the storage consumption.
Currently you need to navigate to the Object Storage page using the web console, select the appropriate bucket to view all the objects and delete the temporary ones.
To simplify the task you have configured the application to save all the temporary data with /temp prefix. You have also decided to use the Command Line Interface (CLI) to perform this operation.
What is the command you should use to speed up the data cleanup? (Choose the best answer.)

• A. oci os object delete -ns vision -bn app-data --prefix /temp
• B. oci os object bulk-delete -ns vision -bn app-data --prefix /temp --force
• C. oci os object delete app-data in vision where prefix = /temp
• D. oci objectstorage bulk-delete -ns vision -bn app-data --prefix /temp --force

One of your development teams has asked for your help to standardize the creation of several compute instances that must be provisioned each day of the week. You initially write several Command Line Interface (CLI) commands with all appropriate configuration parameters to achieve this task later determining this method lacks flexibility.
Which command generates a JSON-based template that Oracle Cloud Infrastructure (OCI) CLI can use to provision these instances on a regular basis? (Choose the best answer.)

• A. oci compute instance create - -generate-cli-skeleton
• B. oci compute instance launch - -generate-full-command-json-input
• C. oci compute provision-instance - -generate-full-command-json-input
• D. oci compute instance launch - -generate-cli-skeleton

A developer has created a file system in Oracle Cloud Infrastructure (OCI) File Storage service. She launches an Oracle Linux compute instance and successfully mounts the file system from the instance.
She then tries writing to the file system from the compute instance using the following command:
touch /mnt/yourmountpoint/helloworld
But gets an error message:
touch: cannot touch '/mnt/yourmountpoint/helloworrld': Permission denied Which is a reason for this error? (Choose the best answer.)

• A. User is not part of any OCI Identity and Access Management group with write permissions to File Storage service.
• B. User is connecting as the default Oracle Linux user 'opc' instead of 'root' user.
• C. Service limits or quota for file system writes have been breached.
• D. 'touch' command is not available in Oracle Linux by default.
