Kafka - Security

You have this Kafka client config:

security.protocol=SSL
ssl.keystore.location=/path/to/keystore
ssl.keystore.password=wrongpass

The client fails to authenticate. What is the most likely cause?

AIncorrect keystore password

BMissing sasl.mechanism property

Csecurity.protocol should be PLAINTEXT

Dssl.keystore.location path is not needed

Step-by-Step Solution

Solution:

Step 1: Check SSL keystore config
The keystore password is set to 'wrongpass', which likely does not match the actual password.
Step 2: Evaluate other options
Missing sasl.mechanism is irrelevant for SSL-only config. PLAINTEXT disables security. Keystore location is required.
Final Answer:
Incorrect keystore password -> Option A
Quick Check:
Wrong password causes SSL auth failure [OK]

Quick Trick: Check passwords carefully for SSL keystore [OK]
