Practice - 5 Tasks

1fill in blank

easy

Complete the code to declare a queue named 'task_queue' in RabbitMQ.

💡 Hint

Common Mistakes

Using exchange name instead of queue name

Using routing key as queue name

The queue name must be 'task_queue' to match the producer and consumer communication.

2fill in blank

medium

Complete the code to publish a message 'Hello World!' to the 'task_queue'.

RabbitMQ

channel.basic_publish(exchange='', routing_key='[1]', body='Hello World!')

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

💡 Hint

Common Mistakes

Using exchange name as routing_key

Using a wrong queue name

The routing_key must be the queue name 'task_queue' to send the message to the correct queue.

3fill in blank

hard

Fix the error in the consumer code to receive messages from 'task_queue'.

RabbitMQ

channel.basic_consume(queue='[1]', on_message_callback=callback, auto_ack=True)

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

💡 Hint

Common Mistakes

Using exchange name instead of queue

Using routing_key instead of queue

The consumer must listen to the queue named 'task_queue' to receive messages sent by the producer.

4fill in blank

hard

Fill both blanks to create a basic producer-consumer pattern: declare queue and publish message.

RabbitMQ

channel.queue_declare(queue='[1]')
channel.basic_publish(exchange='', routing_key='[2]', body='Task message')

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

Atask_queue

Bexchange

Drouting_key

Attempts:

3 left

💡 Hint

Common Mistakes

Using different names for queue and routing_key

Confusing exchange with queue name

Both the queue declaration and the routing_key must use the same queue name 'task_queue' to connect producer and consumer.

5fill in blank

hard

Fill all three blanks to complete the consumer setup: declare queue, consume messages, and start consuming.

RabbitMQ

channel.queue_declare(queue='[1]')
channel.basic_consume(queue='[2]', on_message_callback=callback, auto_ack=True)
channel.[3]()

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

Atask_queue

Cstart_consuming

Dconsume_messages

💡 Hint

Common Mistakes

Using different queue names

Using wrong method to start consuming

The queue must be declared and consumed with the same name 'task_queue'. The method to start consuming messages is 'start_consuming()'.
