Oracle Cloud Infrastructure 2021 Multicloud Architect Associate — Question 42

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 confirm that the maximum number of instances is configured to allow 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? (Choose the best answer.)

Answer options

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

Correct answer: C

Explanation

The correct answer is C because exceeding the compute resource quota would prevent the instance pool from provisioning additional instances, even if the auto-scaling policy indicates it should. Options A and B do not directly address the scaling issue, and D is irrelevant to the resource provisioning problem.
