💡 Hint

Common Mistakes

Using False for durable or wrong queue name.

Setting durable=True makes the queue survive server restarts. The queue name is 'task_queue'. The message is marked persistent with delivery_mode=2.

5fill in blank

hard

Fill all three blanks to set up a consumer with manual message acknowledgment.

RabbitMQ

def callback(ch, method, properties, body):
    print(f"Received {body}")
    ch.basic_ack(delivery_tag=[1])

channel.basic_consume(queue=[2], on_message_callback=callback, auto_ack=[3])

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

Amethod.delivery_tag

B'task_queue'

CFalse

DTrue

💡 Hint

Common Mistakes

Using auto_ack=True disables manual ack.

Wrong queue name or missing delivery_tag.

The delivery_tag is used to acknowledge the message manually. The queue is 'task_queue'. Setting auto_ack=False means manual acknowledgment is required.
