You have a Kafka client application that has real-time processing requirements.
Which Kafka metric should you monitor?
A. Consumer lag between brokers and consumers
B. Total time to serve requests to replica followers
C. Aggregate incoming byte rate
D. Consumer heartbeat rate to group coordinator
正解：A
解説：
For real-time applications, thekey metric to monitor is consumer lag- the difference between thelatest offset on the brokerand thelast committed offset by the consumer.
FromKafka Monitoring Guide:
"Consumer lag is the most important metric for real-time applications. It tells you how far behind the consumer is from the latest data in Kafka."
* B relates to replication, not client responsiveness.
* C tracks group membership stability, not data delay.
* D tracks input throughput, not processing latency.

You have a Kafka Connect cluster with multiple connectors.
One connector is not working as expected.
How can you find logs related to that specific connector?
A. Modify the log4j.properties file to add a dedicated log appender for the connector.
B. Make no change, there is no way to find logs other than by stopping all the other connectors.
C. Change the log level to DEBUG to have connector context information in logs.
D. Modify the log4j.properties file to enable connector context.
正解：A
解説：
To isolate logs for a specific connector, you can configurea separate logger and appenderin theConnect worker's log4j.propertiesfile, using the connector's name as the logging context.
FromKafka Connect Logging Docs:
"Kafka Connect loggers use hierarchical logger names. You can configure per-connector log levels and output files by extending log4j.properties."
* A and C change verbosity but don't separate logs.
* D is false; targeted logging is possible.
