hard📝 Application Q9 of 15
Step-by-Step Solution
Solution:
Step 1: Identify encryption mechanism
Istio's mutual TLS (mTLS) transparently encrypts service-to-service traffic.Step 2: Exclude unrelated features
Gateways manage ingress/egress, VirtualServices route traffic, and resource limits do not affect encryption.Final Answer:
Mutual TLS (mTLS) authentication -> Option DQuick Check:
mTLS secures traffic without app code changes [OK]
Quick Trick: mTLS encrypts traffic transparently [OK]
Common Mistakes:
- Confusing routing with security features
- Thinking gateways handle encryption
