Elasticsearch - Security

Given this snippet in elasticsearch.yml:

 xpack.security.transport.ssl.enabled: true
 xpack.security.transport.ssl.verification_mode: certificate

What is the effect on data transmission between nodes?

AData is encrypted and nodes verify each other's certificates

BData is sent unencrypted between nodes

CData is encrypted but nodes do not verify certificates

DData is compressed but not encrypted

Step-by-Step Solution

Solution:

Step 1: Analyze TLS enabled setting
Setting ssl.enabled: true means data is encrypted during transport.
Step 2: Understand verification_mode: certificate
This means nodes verify each other's TLS certificates to ensure trusted communication.
Final Answer:
Data is encrypted and nodes verify each other's certificates -> Option A
Quick Check:
Encryption + certificate verification = secure transport [OK]

Quick Trick: Verification_mode 'certificate' means nodes check TLS certificates [OK]
