  1. No encryption, no authentication and no authorization
  2. Encryption, but no authentication or authorization
  3. No encryption, no authorization, but have authentication
  4. Encryption and authentication, but no authorization

Answer(s): A

Explanation:

By default, Kafka brokers use the PLAINTEXT protocol for network communication. This means:

No encryption ­ data is sent in plain text.
No authentication ­ any client can connect without verifying identity. No authorization ­ there are no access control checks by default.

Security features like TLS, SASL, and ACLs must be explicitly configured.

connect-configs stores connector configurations.
connect-status tracks the status of connectors and tasks (e.g., RUNNING, FAILED). connect-offsets stores source connector offsets for reading from external systems.

Explanation:

Kafka quotas allow administrators to control and limit the rate of data production and consumption per client (producer/consumer), ensuring fair use of broker resources among multiple clients.



A customer has a use case for a ksqlDB persistent query. You need to make sure that duplicate messages are not processed and messages are not skipped.

  1. processing.guarantee=exactly_once
  2. ksql.streams auto offset.reset=earliest
  3. ksql.streams auto.offset.reset=latest
  4. ksql.fail.on.production.error=false

Answer(s): A

Explanation:

processing.guarantee=exactly_once ensures that messages are processed exactly once by ksqlDB, preventing both duplicates and message loss.
