What is the command to start a Kafka server with the default server properties?

• A. $bin/kafka-server-start.sh config/server.properties
• B. $bin/start-kafka.sh config/server.properties
• C. start kafka-server config/server.properties
• D. kafka-server-start config/kafka.properties

Answer: (A)

To start a Kafka broker with the default server properties, you run the Kafka startup script and point it to the default properties file. The standard command uses the script that launches the broker and loads the configuration from config/server.properties. In practical terms, you execute something like bin/kafka-server-start.sh config/server.properties (or $KAFKA_HOME/bin/kafka-server-start.sh config/server.properties). This loads the default settings for the broker, including the port, log directories, and other baseline defaults. The other options don’t fit because they either reference a non-existent or non-standard script, use an invalid startup syntax, or point to a properties file that isn’t the default (for example, a file named kafka.properties).
