Step-by-Step Solution
Solution:
Step 1: Identify Istio's security method
Istio injects sidecar proxies that transparently encrypt traffic between services using mutual TLS without code changes.Step 2: Eliminate incorrect options
Developers do not need to add encryption code. Istio does not store secrets in a database nor block all external traffic.Final Answer:
By injecting sidecar proxies that handle mutual TLS encryption automatically -> Option DQuick Check:
Istio uses sidecars for automatic encryption = C [OK]
Quick Trick: Istio sidecars add encryption without code changes [OK]
Common Mistakes:
MISTAKES- Thinking developers must add encryption code
- Confusing Istio with secret storage
- Assuming Istio blocks all external traffic
