Identify the error in this Kafka leader election configuration snippet:

broker.id = 2
zookeeper.connect=localhost:2181
controller.quorum.voters=1@localhost:9093,2@localhost:9094

Abroker.id should not have spaces around '='

Bbroker.id must be a string, not a number

Ccontroller.quorum.voters format is incorrect

Dzookeeper.connect is deprecated and should be removed

Step-by-Step Solution

Solution:

Step 1: Check broker.id syntax
Spaces around '=' are allowed in properties files, so no error here.
Step 2: Review zookeeper.connect usage
In newer Kafka versions with KRaft mode, zookeeper.connect is deprecated and should be removed.
Step 3: Validate controller.quorum.voters format
The format 'id@host:port' is correct for controller quorum voters.
Final Answer:
zookeeper.connect is deprecated and should be removed -> Option D
Quick Check:
Deprecated config = zookeeper.connect [OK]

Quick Trick: Remove deprecated zookeeper.connect in KRaft mode [OK]
