Kafka - Security

Given this Kafka client config snippet:

security.protocol=SSL
ssl.keystore.location=/etc/kafka/keystore.jks
ssl.keystore.password=changeit

AClient connects but without encryption

BClient ignores the password and connects successfully

CClient connects but logs a warning

DClient fails to authenticate and cannot connect

Step-by-Step Solution

Solution:

Step 1: Understand role of keystore password
The keystore password unlocks the private keys needed for SSL authentication.
Step 2: Effect of incorrect password
If the password is wrong, client cannot access keys and fails SSL handshake, blocking connection.
Final Answer:
Client fails to authenticate and cannot connect -> Option D
Quick Check:
Wrong keystore password causes connection failure = B [OK]

Quick Trick: Incorrect keystore password blocks SSL handshake [OK]
