💡 Hint

Using incorrect argument keys like 'x-priority' or 'max-priority'.

The argument 'x-max-priority' is used to declare a priority queue in RabbitMQ with a maximum priority value.

💡 Hint

Common Mistakes

Using a priority value outside the declared max priority range.

The priority property sets the message priority. Here, priority 5 is within the allowed range.

3fill in blank

hard

Fix the error in the queue declaration to enable priority support.

RabbitMQ

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

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

💡 Hint

Common Mistakes

Using string instead of integer for priority value.

Using wrong argument keys.

The value for 'x-max-priority' must be an integer, not a string, and the key must be exactly 'x-max-priority'.

Fill both blanks to declare a priority queue and publish a message with priority 7.

RabbitMQ

channel.queue_declare(queue='task_queue', arguments=[1])
channel.basic_publish(exchange='', routing_key='task_queue', body='Task', properties=pika.BasicProperties(priority=[2]))

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

💡 Hint

Common Mistakes

Using wrong keys in queue declaration.

Setting message priority outside allowed range.

Declare the queue with 'x-max-priority' set to 10, then publish a message with priority 7.

5fill in blank

hard

Fill all three blanks to declare a priority queue, publish a high priority message, and consume it.

RabbitMQ

channel.queue_declare(queue='task_queue', arguments=[1])
channel.basic_publish(exchange='', routing_key='task_queue', body='Urgent', properties=pika.BasicProperties(priority=[2]))
method_frame, header_frame, body = channel.basic_get(queue='task_queue', auto_ack=[3])

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

💡 Hint

Common Mistakes

Using incorrect argument keys or values.

Setting auto_ack to False when automatic acknowledgment is intended.

Declare the queue with max priority 15, publish a message with priority 10, and consume it with auto_ack set to True to acknowledge automatically.
