Not setting group.instance.id at all

Setting group.instance.id to a fixed string enables static group membership.

2fill in blank

medium

💡 Hint

Common Mistakes

Confusing group.id with group.instance.id

Setting client.id instead

The property group.instance.id is used to enable static group membership.

3fill in blank

hard

Fix the error in the code to correctly set static group membership in the consumer properties.

💡 Hint

Common Mistakes

Using group.id instead of group.instance.id

Misspelling the property name

The correct property name is group.instance.id to enable static group membership.

4fill in blank

hard

Fill both blanks to create a consumer configuration that enables static group membership with a unique instance ID.

Kafka

consumerProps.put([1], "my-group");
consumerProps.put([2], "instance-123");

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

A"group.id"

B"group.instance.id"

C"client.id"

D"session.timeout.ms"

💡 Hint

Common Mistakes

Swapping the two property names

Using client.id instead of group.instance.id

Set group.id to identify the group and group.instance.id to enable static membership with a unique ID.

5fill in blank

hard

Fill all three blanks to create a Kafka consumer configuration that sets the group ID, static instance ID, and client ID.

Kafka

props.put([1], "my-group");
props.put([2], "static-instance-01");
props.put([3], "client-01");

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

A"group.instance.id"

B"group.id"

C"client.id"

D"session.timeout.ms"

💡 Hint

Common Mistakes

Mixing up the property names

Not setting client.id when required

Set group.id for the group, group.instance.id for static membership, and client.id for the client identifier.
