VM commands (create, start, stop) in Azure - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a new Azure VM using the Azure CLI.

Azure

az vm create --resource-group MyResourceGroup --name MyVM --image UbuntuLTS --admin-username azureuser [1]

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

A--delete

B--start

C--stop

D--generate-ssh-keys

Attempts:

3 left

💡 Hint

Common Mistakes

Using --start or --stop during VM creation is incorrect.

Forgetting to generate SSH keys can block access.

The --generate-ssh-keys option creates SSH keys automatically for secure login when creating a VM.

2fill in blank

medium

Complete the code to start an existing Azure VM.

Azure

az vm [1] --resource-group MyResourceGroup --name MyVM

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

Acreate

Bstart

Cstop

Ddelete

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'create' tries to make a new VM instead of starting.

Using 'stop' will power off the VM.

The start command powers on a stopped VM.

3fill in blank

hard

Fix the error in the command to stop an Azure VM.

Azure

az vm [1] --resource-group MyResourceGroup --name MyVM

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

Astop

Bshutdown

Cpoweroff

Dterminate

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'shutdown' or 'poweroff' are not valid Azure CLI commands.

Using 'terminate' is not recognized.

The correct command to stop a VM is stop. Other options are invalid in Azure CLI.

4fill in blank

hard

Fill both blanks to create and start a VM with SSH keys.

Azure

az vm [1] --resource-group MyResourceGroup --name MyVM --image UbuntuLTS --admin-username azureuser [2]

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

Acreate

B--generate-ssh-keys

Cstart

D--no-wait

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'start' instead of 'create' when making a VM.

Forgetting to generate SSH keys.

Use create to make the VM and --generate-ssh-keys to create SSH keys automatically.

5fill in blank

hard

Fill all three blanks to stop a VM and delete it without waiting.

Azure

az vm [1] --resource-group MyResourceGroup --name MyVM && az vm [2] --resource-group MyResourceGroup --name MyVM [3]

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

Astop

Bdelete

C--no-wait

Dstart

Attempts:

3 left

💡 Hint

Common Mistakes

Trying to delete without stopping first.

Not using --no-wait causes waiting for deletion.

First, stop the VM, then delete it with --no-wait to avoid waiting for completion.

Practice

1. What does the az vm create command do in Azure?

easy

A. It starts an existing virtual machine.

B. It stops a running virtual machine.

C. It creates a new virtual machine in Azure.

D. It deletes a virtual machine.

Solution

1. Step 1: Understand the command purpose

   The az vm create command is used to make a new virtual machine in Azure.

2. Step 2: Compare with other commands

   az vm start starts a VM, az vm stop stops it, and az vm delete removes it.

3. Final Answer:

   It creates a new virtual machine in Azure. -> Option C

4. Quick Check:

   az vm create = create VM [OK]

Hint: Create means make new VM, start means turn on, stop means turn off [OK]

Common Mistakes:

• Confusing create with start or stop commands
• Thinking create also starts the VM automatically
• Mixing stop with delete

2. Which of the following is the correct syntax to start a VM named myVM in resource group myGroup?

easy

A. az vm create --name myVM --resource-group myGroup

B. az vm start --name myVM --resource-group myGroup

C. az vm stop --name myVM --resource-group myGroup

D. az vm delete --name myVM --resource-group myGroup

Solution

1. Step 1: Identify the command to start a VM

   The command to start a VM is az vm start.

2. Step 2: Check the syntax for name and resource group

   The correct flags are --name for VM name and --resource-group for the group.

3. Final Answer:

   az vm start --name myVM --resource-group myGroup -> Option B

4. Quick Check:

   Start VM syntax = az vm start [OK]

Hint: Start VM uses 'az vm start' with --name and --resource-group [OK]

Common Mistakes:

• Using create instead of start to power on VM
• Forgetting to specify resource group
• Using stop or delete commands by mistake

3. What will happen if you run this command?

az vm stop --name testVM --resource-group testGroup

medium

A. The VM named testVM will be stopped (powered off).

B. The VM named testVM will be deleted.

C. The VM named testVM will be started.

D. The command will show a syntax error.

Solution

1. Step 1: Understand the command action

   az vm stop stops (powers off) the specified VM.

2. Step 2: Confirm the VM and resource group names

   The VM name is testVM and resource group is testGroup, both valid inputs.

3. Final Answer:

   The VM named testVM will be stopped (powered off). -> Option A

4. Quick Check:

   az vm stop = stop VM [OK]

Hint: Stop command powers off VM, does not delete or start it [OK]

Common Mistakes:

• Confusing stop with delete
• Thinking stop starts the VM
• Assuming syntax error due to names

4. You tried to start a VM with this command:

az vm start -n myVM -g myGroup

The command failed with an error. What is the likely cause?

medium

A. The VM name or resource group might be misspelled or does not exist.

B. You must stop the VM before starting it.

C. The flags -n and -g are incorrect; use full names instead.

D. The az vm start command cannot use short flags.

Solution

1. Step 1: Check command flags

   -n and -g are valid short forms for --name and --resource-group.

2. Step 2: Consider common errors

   Errors usually happen if the VM or resource group name is wrong or missing in Azure.

3. Final Answer:

   The VM name or resource group might be misspelled or does not exist. -> Option A

4. Quick Check:

   Invalid names cause start errors, not flags [OK]

Hint: Check VM and group names carefully if start fails [OK]

Common Mistakes:

• Assuming short flags are invalid
• Thinking VM must be stopped before starting
• Confusing start errors with syntax errors

5. You want to save money by stopping a VM but keep its data intact. Which command should you use and why?

hard

A. Use az vm stop because it powers off the VM but keeps the disk data.

B. Use az vm delete because it stops and removes the VM and data.

C. Use az vm restart because it stops and starts the VM quickly.

D. Use az vm deallocate because it stops the VM and releases compute resources but keeps data.

Solution

1. Step 1: Understand stopping vs deallocating

   az vm stop powers off the VM but does not release compute resources, so charges continue.

2. Step 2: Identify the command to save costs

   az vm deallocate stops the VM and releases compute resources, saving money while keeping disk data.

3. Final Answer:

   Use az vm deallocate because it stops the VM and releases compute resources but keeps data. -> Option D

4. Quick Check:

   Deallocate = stop + release resources + keep data [OK]

Hint: Deallocate stops VM and saves cost without deleting data [OK]

Common Mistakes:

• Using stop only and expecting cost savings
• Deleting VM to save money loses data
• Restarting does not save costs
