Oracle Cloud Infrastructure 2021 Multicloud Architect Associate — Question 44

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.)

Answer options

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

Correct answer: D

Explanation

The correct answer is D because the 'opc' user does not have the necessary permissions to write to the specified mount point, whereas the 'root' user would have those permissions. Option A is incorrect because the 'touch' command is typically available by default in Oracle Linux. Option B is also incorrect as the quota or service limits are not mentioned as breached in the scenario. Option C is not correct since the issue is related to the user's privileges rather than group membership.
