Kafka - Security

Given this Kafka client config snippet:

security.protocol=SSL
ssl.keystore.location=/path/client.keystore.jks
ssl.truststore.location=/path/client.truststore.jks

What will happen if the truststore file path is incorrect?

AThe client will connect but with a warning logged

BThe client will connect but without encryption

CThe client will ignore the truststore and use default certificates

DThe client will fail to connect due to truststore loading error

Step-by-Step Solution

Solution:

Step 1: Understand truststore role
The truststore contains certificates to verify the broker's identity. If missing or incorrect, verification fails.
Step 2: Predict client behavior on truststore error
Kafka client will fail to establish SSL connection if truststore cannot be loaded or is invalid.
Final Answer:
The client will fail to connect due to truststore loading error -> Option D
Quick Check:
Incorrect truststore causes connection failure [OK]

Quick Trick: Truststore errors block SSL connection, no fallback [OK]
