medium📝 Debug Q6 of 15
Step-by-Step Solution
Solution:
Step 1: Understand wire encryption scope
Wire encryption must be enabled cluster-wide for effective protection.Step 2: Analyze other options
Network hardware typically does not block encryption; Hadoop versions supporting encryption are common; compression does not expose data in clear text.Final Answer:
The encryption setting is enabled on only some nodes, causing inconsistent encryption -> Option BQuick Check:
Partial config leads to unencrypted transfers [OK]
Quick Trick: All nodes must have encryption enabled to secure data [OK]
Common Mistakes:
- Assuming hardware limits encryption
- Ignoring cluster-wide config consistency
- Confusing compression with encryption
