Container Instances combined with Object Storage lifecycle rules
Why it's wrong here
Container instances run isolated containers and lifecycle rules manage data retention.
- ✓
Instance Pools combined with Compute Autoscaling
Why this is correct
Instance pools group similar instances, and autoscaling adjusts the pool size based on rules.
- ✗
Virtual Cloud Network with Dynamic Routing Gateway autoscaling
Why it's wrong here
DRGs do not autoscale compute resources.
