💡 Hint

Common Mistakes

Using '--list' with '--describe' together incorrectly

Omitting the '--group' option when describing a group

The correct option is 'group' to specify the consumer group when listing or describing groups.

💡 Hint

Common Mistakes

Using a wrong or default group name

Omitting the group name

The consumer group to describe is 'my-group' as specified in the instruction.

3fill in blank

Fix the error in the command to monitor consumer lag by completing the missing option.

Kafka

kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe --group my-group --[1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using '--lag' which is not a valid option

Using '--reset-offsets' which changes offsets instead of showing lag

The '--offsets' option is used to show the current offsets and lag for the consumer group.

4fill in blank

hard

Fill both blanks to create a command that resets the consumer group offsets to the earliest position.

Kafka

kafka-consumer-groups.sh --bootstrap-server localhost:9092 --group my-group --[1] --to-[2] earliest --execute

Drag options to blanks, or click blank then click option'

Areset-offsets

Blatest

Cearliest

Ddescribe

Attempts:

3 left

💡 Hint

Common Mistakes

Using '--describe' instead of '--reset-offsets'

Using '--to-latest' instead of '--to-earliest'

The command uses '--reset-offsets' to reset offsets and '--to-earliest' to set them to the earliest position.

5fill in blank

hard

Fill all three blanks to create a command that describes consumer group 'analytics', shows lag, and uses a specific bootstrap server.

Kafka

kafka-consumer-groups.sh --bootstrap-server [1] --describe --group [2] --[3]

Drag options to blanks, or click blank then click option'

Alocalhost:9092

Dmy-group

Attempts:

💡 Hint

Common Mistakes

Using wrong bootstrap server address

Using wrong group name

Omitting the '--offsets' option

The command uses 'localhost:9092' as the bootstrap server, 'analytics' as the group, and '--offsets' to show lag.
