Practice - 5 Tasks

1fill in blank

easy

Complete the code to start Kafka Manager with the default port.

Kafka

bin/kafka-manager [1]

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

A-Dhttp.port=8080

B-Dhttp.port=9092

C-Dhttp.port=7000

D-Dhttp.port=9000

💡 Hint

Common Mistakes

Using common web port 8080 instead of Kafka Manager's default 9000.

Using Kafka broker port 9092 instead of Kafka Manager UI port.

Not specifying any port and expecting it to start automatically.

The default port for Kafka Manager UI is 9000, so you need to specify -Dhttp.port=9000 to start it on that port.

medium

Complete the configuration line to add a Kafka cluster in Kafka Manager.

Kafka

kafka-manager.zkhosts=[1]

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

Alocalhost:2181

Blocalhost:9092

Clocalhost:8080

Dlocalhost:7000

💡 Hint

Common Mistakes

Using Kafka broker port 9092 instead of ZooKeeper port 2181.

Using the Kafka Manager UI port instead of ZooKeeper port.

The zkhosts setting requires the ZooKeeper host and port, which is usually localhost:2181.

3fill in blank

hard

Fix the error in the command to start Kafka Manager with a custom config file.

Kafka

bin/kafka-manager -Dconfig.file=[1]

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

Aconf/application.conf

Bconf/application.txt

Cconf/application.yaml

Dconf/application.json

💡 Hint

Common Mistakes

Using unsupported config file formats like .txt, .json, or .yaml.

Misspelling the config file name.

The Kafka Manager config file must be a .conf file, usually named application.conf.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps topic names to their partition count if partitions are more than 3.

Kafka

{topic: [1] for topic, partitions in topics.items() if partitions [2] 3}

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

Apartitions

B==

C>

D<

💡 Hint

Common Mistakes

Using equality operator instead of greater than.

Mapping topic to topic name instead of partition count.

This comprehension maps each topic to its partition count only if the partition count is greater than 3.

5fill in blank

hard

Fill all three blanks to filter topics with more than 5 partitions and create a dictionary with uppercase topic names and their partition counts.

Kafka

{ [1]: [2] for [3], partitions in topics.items() if partitions > 5 }

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

Atopic.upper()

Bpartitions

Ctopic

Dpartition

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong variable names like 'partition' instead of 'partitions'.

Not converting topic names to uppercase.

The comprehension creates a dictionary with uppercase topic names as keys and their partition counts as values, filtering only topics with more than 5 partitions.
