Practice - 5 Tasks

1fill in blank

easy

💡 Hint

Common Mistakes

Using 'disk_free_limit' instead of 'memory_alarm'.

Searching for 'uptime' which is unrelated.

The memory_alarm keyword shows if the memory alarm is active in RabbitMQ.

2fill in blank

medium

Complete the command to reset the disk alarm on a RabbitMQ node.

RabbitMQ

rabbitmqctl [1] disk_free_alarm

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

Aset_disk_alarm

Bclear_disk_alarm

Creset_disk_alarm

Dstop_disk_alarm

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'clear_disk_alarm' which is not a valid command.

Using 'set_disk_alarm' which sets, not resets.

The reset_disk_alarm command clears the disk alarm on the node.

3fill in blank

hard

Fix the error in the command to set a memory alarm limit to 2GB.

RabbitMQ

rabbitmqctl set_vm_memory_high_watermark [1]

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

A0.2

B2g

C2GB

D0.2GB

Attempts:

3 left

💡 Hint

Common Mistakes

Using '2GB' or '2g' which are invalid formats.

Using '0.2GB' which mixes fraction and units.

The memory watermark is set as a fraction of total RAM, so 0.2 means 20% of RAM.

4fill in blank

hard

Fill both blanks to create a command that disables the memory alarm and then checks its status.

RabbitMQ

rabbitmqctl [1] && rabbitmqctl status | grep [2]

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

Aclear_memory_alarm

Bmemory_alarm

C'memory_alarm'

Dreset_memory_alarm

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'clear_memory_alarm' which is not a valid command.

Not quoting the grep pattern.

Use reset_memory_alarm to disable the alarm, then grep for 'memory_alarm' to check status.

5fill in blank

hard

Fill all three blanks to set a disk free limit to 1GB, verify it, and then reset the disk alarm.

RabbitMQ

rabbitmqctl [1] 1073741824 && rabbitmqctl status | grep [2] && rabbitmqctl [3]

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

Aset_disk_free_limit

B'disk_free_limit'

Creset_disk_alarm

Dset_vm_memory_high_watermark

Attempts:

💡 Hint

Common Mistakes

Using memory commands instead of disk commands.

Not quoting the grep pattern.

Using wrong reset command.

Use set_disk_free_limit with bytes for 1GB, grep 'disk_free_limit' to verify, then reset_disk_alarm to clear the alarm.
