Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
A company is deploying a critical application on GKE and needs to ensure high availability for the Kubernetes control plane and etcd data. Which TWO approaches should they implement? (Choose TWO.)
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
✓
Use a regional GKE cluster with multiple zones
GKE automatically manages control plane availability with regional clusters. For etcd backups, using Velero is a standard approach. Increasing node size does not improve control plane availability. Manual control plane management is not needed in GKE. Single-zone clusters do not provide HA.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Manually manage the control plane on Compute Engine
Why it's wrong here
GKE manages control plane; manual management is not recommended.
- ✗
Increase the machine type of the node pool
Why it's wrong here
Node machine type does not affect control plane HA.
- ✓
Use a regional GKE cluster with multiple zones
Why this is correct
Regional clusters replicate control plane across zones for HA.
- ✗
Use a single-zone cluster with a large node pool
Why it's wrong here
Single-zone is not HA.
- ✓
Use Velero to back up etcd data regularly
Why this is correct
Velero can back up cluster resources and state, including etcd data.
