Creating a VM in Azure Portal - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to select the correct Azure service for creating a virtual machine.

Azure

az [1] create --resource-group MyResourceGroup --name MyVM --image UbuntuLTS

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

Anetwork

Bstorage

Cvm

Dcontainer

💡 Hint

Common Mistakes

Using 'storage' instead of 'vm' will try to create a storage account, not a VM.

Using 'network' or 'container' are unrelated to VM creation.

The vm service is used to create virtual machines in Azure.

Complete the code to specify the size of the VM during creation.

Azure

az vm create --resource-group MyResourceGroup --name MyVM --image UbuntuLTS --size [1]

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

AStandard_B1s

BMyResourceGroup

CUbuntuLTS

DMyVM

Attempts:

💡 Hint

Common Mistakes

Using resource group or VM name instead of a size value.

Using the image name where size is expected.

The --size parameter specifies the VM size, such as Standard_B1s.

Fix the error in the command to create a VM with SSH key authentication.

Azure

az vm create --resource-group MyResourceGroup --name MyVM --image UbuntuLTS --authentication-type [1] --ssh-key-value ~/.ssh/id_rsa.pub

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

Apassword

Bssh-key

Cssh

Dkey

Attempts:

💡 Hint

Common Mistakes

Using 'password' instead of 'ssh-key' disables SSH key authentication.

Using incomplete or incorrect authentication types like 'ssh' or 'key'.

The correct value for SSH key authentication is ssh-key.

4fill in blank

Fill both blanks to create a VM with a specific OS disk size and public IP SKU.

Azure

az vm create --resource-group MyResourceGroup --name MyVM --image UbuntuLTS --os-disk-size-gb [1] --public-ip-sku [2]

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

A128

BStandard

CBasic

D64

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing disk size with IP SKU values.

Using '64' for disk size when a larger size is needed.

Choosing 'Basic' when 'Standard' is required.

The OS disk size is set to 128 GB and the public IP SKU to Standard for better performance.

5fill in blank

hard

Fill all three blanks to create a VM with a custom admin username, disable password authentication, and enable boot diagnostics.

Azure

az vm create --resource-group MyResourceGroup --name MyVM --image UbuntuLTS --admin-username [1] --disable-password-authentication [2] --boot-diagnostics [3]

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

Aazureuser

Btrue

Dfalse

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'false' for disabling password authentication when it should be 'true'.

Forgetting to enable boot diagnostics by setting it to 'true'.

Using an invalid admin username.

The admin username is set to azureuser, password authentication is disabled with true, and boot diagnostics is enabled with true.

Practice

1. What is the first step when creating a Virtual Machine (VM) in the Azure Portal?

easy

A. Choose the VM name and region

B. Connect to the VM using SSH

C. Select the VM size after creation

D. Install software on the VM

Solution

1. Step 1: Start VM creation in Azure Portal

   When creating a VM, you first open the Azure Portal and start the 'Create a virtual machine' process.

2. Step 2: Enter basic details like name and region

   The first required details are the VM's name and the region where it will be hosted.

3. Final Answer:

   Choose the VM name and region -> Option A

4. Quick Check:

   First step is naming and region selection [OK]

Hint: Name and region come first when creating a VM [OK]

Common Mistakes:

• Trying to connect before VM is created
• Selecting size before naming VM
• Installing software before VM setup

2. Which option correctly describes the step to select the operating system image when creating a VM in Azure Portal?

easy

A. Skip image selection; Azure picks automatically

B. Choose the image after VM creation

C. Upload your own OS image only

D. Select the image during VM setup under 'Image' section

Solution

1. Step 1: Locate the 'Image' section in VM creation

   During VM setup, there is a section called 'Image' where you select the OS image.

2. Step 2: Select a predefined OS image

   You pick from available images like Windows Server or Ubuntu Linux before creating the VM.

3. Final Answer:

   Select the image during VM setup under 'Image' section -> Option D

4. Quick Check:

   Image selection happens during setup [OK]

Hint: Pick OS image during VM setup, not after [OK]

Common Mistakes:

• Thinking image is chosen after VM is created
• Assuming Azure picks image automatically
• Believing you must upload your own image

3. After creating a Linux VM in Azure Portal, which method is used to connect to it?

medium

A. Remote Desktop Protocol (RDP)

B. SSH (Secure Shell)

C. FTP (File Transfer Protocol)

D. HTTP (Hypertext Transfer Protocol)

Solution

1. Step 1: Identify the OS type of the VM

   The VM is Linux-based, which typically uses SSH for secure command-line access.

2. Step 2: Use SSH to connect

   SSH is the standard protocol to connect securely to Linux VMs remotely.

3. Final Answer:

   SSH (Secure Shell) -> Option B

4. Quick Check:

   Linux VM connection uses SSH [OK]

Hint: Linux VMs connect via SSH, Windows via RDP [OK]

Common Mistakes:

• Trying to use RDP on Linux VM
• Using FTP or HTTP to connect to VM
• Confusing protocols for connection

4. You created a Windows VM but cannot connect using Remote Desktop. What is the most likely cause?

medium

A. Network security group (NSG) blocks RDP port 3389

B. The VM size is too small

C. You selected a Linux image by mistake

D. The VM name is invalid

Solution

1. Step 1: Check network security settings

   Remote Desktop uses port 3389, which must be allowed in the VM's network security group (NSG).

2. Step 2: Identify blocked port issue

   If NSG blocks port 3389, RDP connections fail even if VM is running.

3. Final Answer:

   Network security group (NSG) blocks RDP port 3389 -> Option A

4. Quick Check:

   Blocked RDP port causes connection failure [OK]

Hint: Open port 3389 in NSG for Windows VM RDP [OK]

Common Mistakes:

• Assuming VM size affects RDP connection
• Confusing OS image type after creation
• Thinking VM name affects connectivity

5. You want to create a VM in Azure Portal that can be accessed securely from anywhere. Which combination of settings is best?

hard

A. Use a Linux VM, use password authentication, block all inbound ports

B. Use a Windows VM, use password authentication, open port 3389 to all IPs

C. Use a Linux VM, select SSH key authentication, open port 22 in NSG

D. Use a Windows VM, disable NSG, connect via RDP

Solution

1. Step 1: Choose secure authentication method

   SSH key authentication is more secure than passwords for Linux VMs.

2. Step 2: Open only necessary port in NSG

   Opening port 22 for SSH allows secure remote access; avoid opening unnecessary ports.

3. Step 3: Avoid insecure options

   Opening RDP port 3389 to all IPs or disabling NSG reduces security.

4. Final Answer:

   Use a Linux VM, select SSH key authentication, open port 22 in NSG -> Option C

5. Quick Check:

   SSH key + port 22 open = secure access [OK]

Hint: Use SSH keys and open only port 22 for secure Linux VM access [OK]

Common Mistakes:

• Using password authentication over SSH
• Opening RDP port to all IPs
• Disabling NSG for convenience
