💡 Hint

Common Mistakes

Using 'create' instead of 'list' will try to create a topic.

Using 'delete' will remove topics, which is not intended here.

The --list option shows all topics in Kafka.

Complete the command to create a topic named 'my-topic' with 3 partitions.

💡 Hint

Common Mistakes

Using 0 partitions is invalid and causes an error.

Using 1 partition creates only a single partition, not 3.

The --partitions option sets how many partitions the topic will have. Here, 3 is specified.

3fill in blank

hard

Fix the error in the command to describe a topic named 'orders'.

Kafka

kafka-topics.sh --bootstrap-server localhost:9092 --[1] orders

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

Bcreate

Clist

Ddelete

Attempts:

💡 Hint

Common Mistakes

Using 'list' will show all topics, not details of one.

Using 'create' or 'delete' will change topics, not describe.

The --describe option shows details about a specific topic.

4fill in blank

hard

Fill both blanks to consume messages from 'my-topic' starting from the beginning.

Kafka

kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic my-topic --[1] --[2]

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

Afrom-beginning

Bgroup

Coffset

Dpartition

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'offset' or 'partition' options here is incorrect for this purpose.

Omitting the consumer group can cause unexpected behavior.

The --from-beginning option starts consuming from the start of the topic. The --group option sets the consumer group.

5fill in blank

hard

Fill all three blanks to produce a message 'Hello' to 'my-topic' using the console producer.

Kafka

echo "Hello" | kafka-console-producer.sh --bootstrap-server localhost:9092 --topic [1] --[2] [3]

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

Amy-topic

Bproperty

Cacks

Dretries

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing 'acks' with 'retries' changes message delivery guarantees.

Omitting '--property' causes the producer to use defaults.

The topic name is 'my-topic'. The --property option sets producer properties like acks which controls message acknowledgment.
