source.bootstrap.servers=[1]

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

A"target.kafka:9092"

B"source.kafka:9092"

C"localhost:9092"

D"mirror.kafka:9092"

💡 Hint

Common Mistakes

Using the target cluster address instead of the source cluster.

Leaving the value empty or with incorrect format.

The source.bootstrap.servers property must point to the source Kafka cluster's address, such as "source.kafka:9092".

medium

Complete the code to specify the target cluster in MirrorMaker 2 configuration.

Kafka

target.bootstrap.servers=[1]

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

A"source.kafka:9092"

B"mirror.kafka:9092"

C"localhost:9092"

D"target.kafka:9092"

💡 Hint

Common Mistakes

Using the source cluster address instead of the target cluster.

Using an invalid or empty address.

The target.bootstrap.servers property must point to the target Kafka cluster's address, such as "target.kafka:9092".

3fill in blank

hard

Fix the error in the MirrorMaker 2 configuration property to enable topic replication.

Kafka

replication.policy.class=[1]

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

A"org.apache.kafka.connect.mirror.DefaultReplicationPolicy"

B"org.apache.kafka.connect.mirror.TopicReplicationPolicy"

C"org.apache.kafka.connect.mirror.MirrorReplicationPolicy"

D"org.apache.kafka.connect.mirror.SimpleReplicationPolicy"

Attempts:

💡 Hint

Common Mistakes

Using a non-existent or incorrect class name.

Misspelling the class path.

The correct class for replication policy in MirrorMaker 2 is org.apache.kafka.connect.mirror.DefaultReplicationPolicy.

4fill in blank

hard

Fill both blanks to configure MirrorMaker 2 to replicate topics with a specific prefix and exclude internal topics.

Kafka

topics=[1]
topics.exclude=[2]

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

A"prefix-.*"

B"__consumer_offsets"

C"__transaction_state"

D"internal-.*"

Attempts:

💡 Hint

Common Mistakes

Using incorrect regex patterns.

Not excluding internal topics which can cause replication issues.

Use "prefix-.*" to include topics starting with 'prefix-' and exclude internal topics like "__consumer_offsets".

5fill in blank

hard

Fill all three blanks to configure MirrorMaker 2 with source, target, and replication policy settings.

Kafka

clusters=[1]
source.bootstrap.servers=[2]
replication.policy.class=[3]

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

A"source,target"

B"source.kafka:9092"

C"org.apache.kafka.connect.mirror.DefaultReplicationPolicy"

D"target.kafka:9092"

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing source and target addresses.

Incorrect replication policy class name.

Wrong cluster list format.

Set clusters to "source,target", source bootstrap servers to "source.kafka:9092", and replication policy class to org.apache.kafka.connect.mirror.DefaultReplicationPolicy.
