Practice - 5 Tasks

1fill in blank

easy

Complete the command to join a RabbitMQ node to an existing cluster.

RabbitMQ

rabbitmqctl [1] rabbit@node1

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

Astart_app

Bjoin_cluster

Cstop_app

Dreset

💡 Hint

Common Mistakes

Using 'start_app' instead of 'join_cluster' will not join the node to the cluster.

Using 'stop_app' or 'reset' will not join the node to the cluster.

The join_cluster command is used to join a RabbitMQ node to an existing cluster.

2fill in blank

medium

Complete the command to stop the RabbitMQ application on a node before joining a cluster.

RabbitMQ

rabbitmqctl [1]

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

Astop_app

Bstatus

Creset

Dstart_app

💡 Hint

Common Mistakes

Using 'start_app' will start the application instead of stopping it.

Using 'reset' will reset the node, which is not needed here.

You must stop the RabbitMQ application on the node before joining it to a cluster using stop_app.

3fill in blank

hard

Fix the error in the command to reset a RabbitMQ node before joining a cluster.

RabbitMQ

rabbitmqctl [1]

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

Areset

Bstop_app

Cjoin_cluster rabbit@node1

Dstart_app

Attempts:

3 left

💡 Hint

Common Mistakes

Adding arguments to 'reset' causes syntax errors.

Using 'join_cluster' before resetting causes errors.

The reset command clears the node's state, preparing it to join a cluster.

4fill in blank

hard

Fill both blanks to correctly sequence commands to join a node to a RabbitMQ cluster.

RabbitMQ

rabbitmqctl [1] && rabbitmqctl [2] rabbit@node1

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

Astop_app

Bstart_app

Cjoin_cluster

Dreset

Attempts:

3 left

💡 Hint

Common Mistakes

Starting the app before joining causes errors.

Resetting after joining is incorrect.

First stop the app with stop_app, then join the cluster with join_cluster.

5fill in blank

hard

Fill all three blanks to reset, join, and start a RabbitMQ node in a cluster.

RabbitMQ

rabbitmqctl [1] && rabbitmqctl [2] rabbit@node1 && rabbitmqctl [3]

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

Areset

Bjoin_cluster

Cstart_app

Dstop_app

Attempts:

3 left

💡 Hint

Common Mistakes

Starting app before joining causes failure.

Not resetting can cause cluster conflicts.

Reset the node, join the cluster, then start the application.
