Oracle Cloud Infrastructure 2021 Multicloud Architect Associate — Question 19

Your customer is running a set of compute instances inside a private subnet to manage their workloads on Oracle Cloud Infrastructure (OCI) tenancy. You have set up auto scaling feature to provide consistent performance to their end users during period of high demand.
Which step should be met for auto scaling to work? (Choose the best answer.)

Answer options

• A. OS Management Service agent (osms) must be installed on the instances.
• B. Audit logs for the instances should be enabled.
• C. Service gateway should be setup to allow instances to send metrics to monitoring service.
• D. Monitoring for the instances should not be enabled.

Correct answer: C

Explanation

The correct answer is C because a service gateway is necessary for instances in a private subnet to communicate with the monitoring service and send metrics, which are crucial for auto scaling. Option A is incorrect as the OS Management Service agent is not a requirement for auto scaling. Option B is not relevant to the auto scaling function, and option D contradicts the need for monitoring, which is essential for effective auto scaling.
