Cluster node types (disc, RAM) in RabbitMQ - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the command to start a RabbitMQ node as a RAM node.

RabbitMQ

rabbitmq-server -[1]

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

💡 Hint

Common Mistakes

Using -disc instead of -ram

Omitting the node type option

Using unrelated commands like start or stop

Using -ram starts the node as a RAM node, which keeps state in memory.

2fill in blank

medium

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

RabbitMQ

rabbitmqctl join_cluster --ram [1]

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

Areset

Bstart

Cstop

Dnode@hostname

💡 Hint

Common Mistakes

Using commands like start or stop instead of node name

Omitting the node name

Using reset which is unrelated here

The join_cluster --ram command requires the name of the cluster node to join, like node@hostname.

3fill in blank

hard

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

RabbitMQ

rabbitmqctl [1]

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

Areset

Bjoin_cluster

Cstop

Dstart

💡 Hint

Common Mistakes

Using start or stop instead of reset

Using join_cluster without resetting first

The reset command clears the node state, which is required before joining a cluster.

4fill in blank

hard

Fill both blanks to create a disc node and join it to a cluster.

RabbitMQ

rabbitmq-server -[1] & rabbitmqctl join_cluster [2]

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

Adisc

Bnode@host1

Cram

Dnode@host2

Attempts:

💡 Hint

Common Mistakes

Using -ram instead of -disc

Joining with wrong node name

Starting with -disc creates a disc node. Then joining the cluster requires the cluster node name like node@host1.

5fill in blank

hard

Fill all three blanks to reset a RAM node, start it, and join a cluster.

RabbitMQ

rabbitmqctl [1] && rabbitmq-server -[2] & rabbitmqctl join_cluster --ram [3]

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

Areset

Bram

Cnode@cluster1

Ddisc

Attempts:

3 left

💡 Hint

Common Mistakes

Starting as disc node instead of RAM

Not resetting before joining

Using wrong cluster node name

Reset clears the node state. Starting with -ram makes it a RAM node. Joining the cluster uses the cluster node name.
