1Z0-1085-26 Core Oci Services Practice Question

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.
