Check if RabbitMQ management plugin is enabled

You run the command rabbitmq-plugins list on your server. Which output line confirms the management plugin is enabled?

RabbitMQ

rabbitmq-plugins list

A [ ] rabbitmq_management_agent

B [ ] rabbitmq_management

C [E] rabbitmq_web_dispatch

D [E] rabbitmq_management

Purpose of RabbitMQ HTTP API

What is the main purpose of the RabbitMQ HTTP API provided by the management plugin?

A To replace the AMQP protocol for all messaging

B To send messages directly to queues using HTTP POST requests

C To allow programmatic access to monitor and manage RabbitMQ via HTTP requests

D To configure RabbitMQ server settings only via command line

💡 Hint

Think about what HTTP APIs usually do for services.

The HTTP API lets users monitor and manage RabbitMQ remotely using HTTP calls. It does not replace AMQP or send messages directly.

❓ Configuration

Enable RabbitMQ management plugin on a server

Which command correctly enables the RabbitMQ management plugin on a server?

A rabbitmq-plugins enable rabbitmq_management

B rabbitmqctl enable_plugin rabbitmq_management

C rabbitmq-plugins start rabbitmq_management

D rabbitmqctl start_plugin rabbitmq_management

💡 Hint

The command uses 'rabbitmq-plugins' and 'enable'.

The correct command to enable a plugin is 'rabbitmq-plugins enable '.

HTTP API returns 401 Unauthorized error

You try to access the RabbitMQ HTTP API but get a 401 Unauthorized error. What is the most likely cause?

A You did not provide valid username and password for HTTP API access

B The RabbitMQ server is not running

C The management plugin is disabled

D The HTTP API endpoint URL is incorrect

💡 Hint

401 means unauthorized access.

401 Unauthorized means the server requires valid credentials which were not provided or were wrong.

Sequence to monitor queue message count via HTTP API

What is the correct sequence of steps to monitor the message count of a queue named 'task_queue' using the RabbitMQ HTTP API?

A 3,2,1,4

B 1,2,3,4

C 1,3,2,4

D 2,1,3,4

💡 Hint

You must enable plugin before using API and authenticate before requesting data.

First enable the plugin, then authenticate, then request queue info, then parse the response.
