Oracle Cloud Infrastructure 2019 Developer Associate — Question 91

You have multiple applications installed on a compute instance and these applications generate a large amount of log files. These log files must reside on the boot volume for a minimum of 15 days and must be retained for at least 60 days. The 60-day retention requirement is causing an issue with available disk space.
What are the two recommended methods to provide additional boot volume space for this compute instance? (Choose two.)

Answer options

• A. Terminate the instance while preserving the boot volume. Create a new instance from the boot volume and select a DenseIO shape to take advantage of local NVMe storage.
• B. Create an object storage bucket and use a script that runs daily to move log files older than 15 days to the bucket.
• C. Create and attach a block volume to the compute instance and copy the log files.
• D. Create a custom image and launch a new compute instance with a larger boot volume size.
• E. Write a custom script to remove the log files on a daily basis and free up the space on the boot volume.

Correct answer: B, C

Explanation

Option B is correct as it effectively offloads older log files to an object storage bucket, thereby freeing up space on the boot volume while satisfying the retention requirement. Option C is also correct because attaching a block volume allows for additional storage, enabling the log files to be stored without filling up the boot volume. The other options either do not address the space issue directly or do not provide effective long-term solutions.
