Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disabling mTLS for performance
Why it's wrong here
Disabling mTLS is a security risk and not an HA strategy.
- ✓
Locality-aware load balancing
Why this is correct
Ensures traffic failover within the region/zone.
- ✗
Using a single ingress gateway for all traffic
Why it's wrong here
This creates a single point of failure.
- ✓
Cross-cluster service failover
Why this is correct
Ensures requests reach another cluster if the primary fails.
- ✓
Running the control plane in multiple clusters
Why this is correct
Avoids single point of failure.
