An administrator is configuring autoscaling on an OCI Instance Pool. They notice that the autoscaling configuration is not triggering scale-out actions despite high CPU utilization. What is a likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The autoscaling policy threshold or cooldown period is misconfigured
Autoscaling requires a co-configured scaling policy with defined thresholds and cooldown periods linked to the instance pool. If the cooldown period is active or thresholds are improperly configured, scaling won't occur.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The VCN Security List lacks an inbound rule for autoscaling metrics
Why it's wrong here
Autoscaling telemetry is handled internally by OCI Monitoring and does not require custom ingress security list rules.
- ✗
The instance pool is attached to an Internet Gateway instead of a NAT Gateway
Why it's wrong here
Gateways do not affect compute autoscaling logic.
- ✗
The compute instances are using Flexible shapes instead of Bare Metal
Why it's wrong here
Flexible shapes fully support autoscaling instance pools.
- ✓
The autoscaling policy threshold or cooldown period is misconfigured
Why this is correct
Improper metric thresholds or active cooldown periods prevent trigger actions.
