Practice - 5 Tasks

1fill in blank

easy

Complete the code to declare a durable queue in RabbitMQ.

RabbitMQ

channel.queue_declare(queue='task_queue', durable=[1])

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

BTrue

C'yes'

💡 Hint

Common Mistakes

Using a string instead of a boolean

Setting durable to False

Setting durable=True makes the queue survive RabbitMQ restarts.

2fill in blank

medium

Complete the code to publish a persistent message to a queue.

RabbitMQ

channel.basic_publish(exchange='', routing_key='task_queue', body=message, properties=pika.BasicProperties(delivery_mode=[1]))

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

B0

C2

D3

💡 Hint

Common Mistakes

Using delivery_mode=1 which is non-persistent

Using delivery_mode=0 which is invalid

Setting delivery_mode=2 marks the message as persistent.

3fill in blank

hard

Fix the error in the code to ensure both queue and messages are durable.

RabbitMQ

channel.queue_declare(queue='task_queue', durable=[1])
channel.basic_publish(exchange='', routing_key='task_queue', body=message, properties=pika.BasicProperties(delivery_mode=[2]))

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

AFalse

BTrue

C1

D2

💡 Hint

Common Mistakes

Mixing up delivery_mode values

Not setting queue durable to True

Queue must be declared with durable=True and messages published with delivery_mode=2 for full durability.

4fill in blank

hard

Fill both blanks to declare a durable queue and publish a persistent message with correct properties.

RabbitMQ

channel.queue_declare(queue='[1]', durable=[2])
channel.basic_publish(exchange='', routing_key='[1]', body=msg, properties=pika.BasicProperties(delivery_mode=2))

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

💡 Hint

Common Mistakes

Using different queue names

Setting durable to False

The queue name must be consistent and durable set to True for persistence.

5fill in blank

hard

Fill all three blanks to declare a durable queue, publish a persistent message, and set message expiration to 60000 ms.

RabbitMQ

channel.queue_declare(queue='[1]', durable=[2])
channel.basic_publish(exchange='', routing_key='[1]', body=msg, properties=pika.BasicProperties(delivery_mode=[3], expiration='60000'))

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

Atask_queue

BTrue

C2

DFalse

💡 Hint

Common Mistakes

Using delivery_mode other than 2

Setting durable to False

Mismatched queue names

Queue name and durability must match, delivery_mode 2 makes message persistent, expiration sets TTL in ms.
