Multiple teams are sharing a tenancy in OracleCloud 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 an Identity and Access Management (IAM) group for each team. Create an OCI budget for each group to track spending.
• B. 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.
• C. Create separate compartment for each team. Use the OCI cost analysis tools to filter costs by compartment.
• 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 data. 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 objectstorage bulk-delete -ns vision -bn app-data --prefix /temp --force
• B. oci os object bulk-delete -ns vision -bn app-data --prefix /temp --force
• C. oci os object delete -ns vision -bn app-data --prefix /temp
• D. oci os object delete app-data in vision where prefix = /temp

You have a web application running on Oracle Cloud Infrastructure (OCI) that lets users log in with a username and password. You notice that an attacker has tried to use SQL comment "--" to alter the database query, remove the password check and log in as a user. You decide to prevent any future attacks.
Which of the following OCI services or features would you choose tosafeguard your application? (Choose the best answer.)

• A. Vault
• B. Data Safe
• C. Web Application Framework (WAF)
• D. Network Security Group

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

Which two statements about the OracleCloud Infrastructure (OCI) Command Line Interface (CLI) are TRUE?
(Choose two.)

• A. You can filter CLI output using the JMESPath query option for JSON.
• B. The CLI provides the same core functionality as the Console, plus additional commands.
• 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 allows you to use the Python language to interact with OCI APIs.
