Public IP addresses in Azure - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a static public IP address in Azure.

Azure

az network public-ip create --resource-group myResourceGroup --name myPublicIP --allocation-method [1]

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

Bdynamic

Cautomatic

Dstatic

💡 Hint

Common Mistakes

Using 'dynamic' will assign an IP that can change.

Using 'manual' or 'automatic' are not valid allocation methods.

The allocation-method must be set to static to reserve a fixed public IP address.

Complete the code to associate a public IP address with a network interface.

Azure

az network nic ip-config update --resource-group myResourceGroup --nic-name myNic --name ipconfig1 --public-ip-address [1]

💡 Hint

Common Mistakes

Using virtual network or subnet names instead of the public IP name.

Confusing network security group (NSG) with public IP.

The --public-ip-address parameter requires the name of the public IP resource to associate.

3fill in blank

hard

Fix the error in the command to create a public IP with DNS name prefix.

Azure

az network public-ip create --resource-group myResourceGroup --name myPublicIP --allocation-method static --dns-name [1]

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

💡 Hint

Common Mistakes

Using resource group or NIC names as DNS labels.

Leaving the DNS name empty or invalid.

The --dns-name should be a unique DNS label, not a resource group or NIC name.

4fill in blank

Fill both blanks to create a public IP with a SKU and IP version.

Azure

az network public-ip create --resource-group myResourceGroup --name myPublicIP --sku [1] --ip-version [2]

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

💡 Hint

Common Mistakes

Mixing SKU and IP version values.

Using lowercase values which may cause errors.

The --sku can be Standard or Basic. The --ip-version can be IPv4 or IPv6. Here, Standard SKU and IPv4 are chosen.

5fill in blank

hard

Fill all three blanks to create a public IP with static allocation, Standard SKU, and IPv6 version.

Azure

az network public-ip create --resource-group myResourceGroup --name myPublicIP --allocation-method [1] --sku [2] --ip-version [3]

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

💡 Hint

Common Mistakes

Using 'dynamic' instead of 'static' for allocation.

Confusing SKU names or IP versions.

To create a public IP with static allocation, Standard SKU, and IPv6, use static for allocation-method, Standard for SKU, and IPv6 for IP version.

Practice

1.

What is the main purpose of a Public IP address in Azure?

easy

A. To allow cloud resources to connect to the internet

B. To secure internal communication within a virtual network

C. To store data securely in the cloud

D. To monitor resource usage and billing

Solution

1. Step 1: Understand Public IP role

   Public IP addresses enable resources to communicate over the internet.

2. Step 2: Compare options

   Only To allow cloud resources to connect to the internet describes internet connectivity, others describe unrelated functions.

3. Final Answer:

   To allow cloud resources to connect to the internet -> Option A

4. Quick Check:

   Public IP = Internet access [OK]

Hint: Public IP means internet access for resources [OK]

Common Mistakes:

• Confusing Public IP with internal network IP
• Thinking Public IP stores data
• Mixing Public IP with monitoring tools

2.

Which option correctly defines a Static Public IP address in Azure?

publicIpAllocationMethod: ?

easy

A. "Fixed"

B. "Dynamic"

C. "Manual"

D. "Static"

Solution

1. Step 1: Recall allocation methods

   Azure uses "Static" and "Dynamic" as valid allocation methods for Public IPs.

2. Step 2: Identify correct syntax

   "Static" is the exact string to assign for fixed IP allocation.

3. Final Answer:

   "Static" -> Option D

4. Quick Check:

   Static = fixed IP allocation [OK]

Hint: Static means fixed IP, use exact string "Static" [OK]

Common Mistakes:

• Using "Manual" or "Fixed" which are invalid values
• Confusing "Dynamic" with static allocation
• Omitting quotes around the string

3.

Given this Azure CLI command, what will be the SKU of the created Public IP?

az network public-ip create --name MyIP --resource-group MyGroup --sku Standard --allocation-method Static

medium

A. Standard

B. Basic

C. Premium

D. Dynamic

Solution

1. Step 1: Identify SKU parameter

   The command includes "--sku Standard", which sets the SKU to Standard.

2. Step 2: Understand SKU options

   Standard and Basic are common SKUs; Premium is not valid here, Dynamic is allocation method.

3. Final Answer:

   Standard -> Option A

4. Quick Check:

   --sku Standard means Standard SKU [OK]

Hint: Look for --sku value to find SKU type [OK]

Common Mistakes:

• Confusing allocation method with SKU
• Assuming default SKU is Basic without checking
• Selecting Dynamic which is not a SKU

4.

Identify the error in this Azure Resource Manager (ARM) template snippet for a Public IP:

{
  "type": "Microsoft.Network/publicIPAddresses",
  "apiVersion": "2021-02-01",
  "name": "myPublicIP",
  "properties": {
    "publicIPAllocationMethod": "Static",
    "sku": "Standard"
  }
}

medium

A. "name" must be inside "properties"

B. "sku" should be outside "properties" block

C. "publicIPAllocationMethod" value should be "Dynamic"

D. "apiVersion" is invalid

Solution

1. Step 1: Check ARM template structure

   In ARM templates, "sku" is a top-level property, not inside "properties".

2. Step 2: Validate other fields

   "publicIPAllocationMethod" can be "Static" inside properties; "name" is correctly placed; "apiVersion" is valid.

3. Final Answer:

   "sku" should be outside "properties" block -> Option B

4. Quick Check:

   SKU location in ARM = outside properties [OK]

Hint: "sku" is a sibling of "properties", not inside it [OK]

Common Mistakes:

• Placing "sku" inside properties
• Changing allocation method unnecessarily
• Misplacing "name" property

5.

You want a Public IP that never changes and offers better reliability for a production web app. Which combination should you choose?

hard

A. Dynamic allocation with Basic SKU

B. Static allocation with Basic SKU

C. Static allocation with Standard SKU

D. Dynamic allocation with Standard SKU

Solution

1. Step 1: Understand allocation methods

   Static allocation ensures the IP address does not change over time.

2. Step 2: Choose SKU for reliability

   Standard SKU provides better features and reliability than Basic SKU.

3. Step 3: Combine for production needs

   Static allocation with Standard SKU fits production web app requirements.

4. Final Answer:

   Static allocation with Standard SKU -> Option C

5. Quick Check:

   Static + Standard = fixed, reliable IP [OK]

Hint: Static + Standard SKU = fixed and reliable IP [OK]

Common Mistakes:

• Choosing Dynamic allocation for fixed IP needs
• Using Basic SKU for production reliability
• Mixing SKU and allocation method incorrectly
