Quiz 5 of 5: Add-ons, storage and operations
13
You customised the VPC CNI add-on (prefix delegation). Which resolve-conflicts option keeps your settings during an update?
Why: OVERWRITE resets fields to AWS defaults and can break Pod IP assignment. PRESERVE keeps customised values; keep customisation in configuration values under version control.
14
Which StorageClass setting avoids creating an EBS volume in the wrong zone?
Why: EBS volumes are zonal. WaitForFirstConsumer delays provisioning until the scheduler has placed the Pod, so the volume is created in that zone.
15
What is the correct order for an EKS cluster upgrade?
Why: Nodes may lag the control plane within the supported skew but never lead it, and add-ons must support the new control-plane version before nodes roll. Prepare first and verify afterwards.
