💡 Hint

Common Mistakes

Using the storage account name instead of the Function App name.

Confusing resource group name with Function App name.

The --name parameter specifies the name of the Function App to create. Here, myFunctionApp is the correct name.

💡 Hint

Common Mistakes

Using an unsupported runtime value.

Mixing runtime with location or storage account.

The --runtime option sets the runtime stack. Here, python is used to create a Python Function App.

Fix the error in the command to create a Function App with a consumption plan location.

Azure

az functionapp create --resource-group myResourceGroup --consumption-plan-location [1] --runtime python --name myFunctionApp --storage-account mystorageaccount

💡 Hint

Common Mistakes

Using resource names instead of region names for location.

Confusing storage account or resource group names with location.

The --consumption-plan-location requires a valid Azure region like eastus2. Other options are incorrect because they are resource names, not locations.

Fill both blanks to create a Function App with a specified runtime and storage account.

Azure

az functionapp create --resource-group myResourceGroup --consumption-plan-location westus --runtime [1] --name myFunctionApp --storage-account [2]

💡 Hint

Common Mistakes

Swapping runtime and storage account values.

Using the Function App name as storage account.

The --runtime should be set to python for a Python Function App, and --storage-account should be the name of the storage account, here mystorageaccount.

hard

Fill all three blanks to create a Function App with a resource group, runtime, and storage account.

Azure

az functionapp create --resource-group [1] --consumption-plan-location eastus --runtime [2] --name myFunctionApp --storage-account [3]

💡 Hint

Common Mistakes

Using location name as resource group.

Mixing runtime and storage account names.

The --resource-group is myResourceGroup, --runtime is python, and --storage-account is mystorageaccount. These are required to create the Function App correctly.

Practice

1. What is the main purpose of an Azure Function App?

easy

A. To run small pieces of code in the cloud without managing servers

B. To store large amounts of data in the cloud

C. To create virtual machines for hosting websites

D. To manage user identities and access

Solution

1. Step 1: Understand Azure Function App purpose

   Azure Function Apps are designed to run code triggered by events without needing to manage servers.

2. Step 2: Compare options

   Options A, B, and D describe other Azure services like virtual machines, storage, and identity management, not Function Apps.

3. Final Answer:

   To run small pieces of code in the cloud without managing servers -> Option A

4. Quick Check:

   Function Apps run code serverlessly [OK]

Hint: Function Apps run code without servers [OK]

Common Mistakes:

• Confusing Function Apps with storage services
• Thinking Function Apps create virtual machines
• Mixing up Function Apps with identity services

2. Which Azure CLI command correctly creates a Function App named myfuncapp in resource group mygroup with a storage account mystorage and runtime python?

easy

A. az function create --resource mygroup --name myfuncapp --storage-account mystorage --runtime python

B. az functionapp new --group mygroup --app-name myfuncapp --storage mystorage --runtime python

C. az create functionapp --resource-group mygroup --name myfuncapp --storage mystorage --runtime python

D. az functionapp create --resource-group mygroup --name myfuncapp --storage-account mystorage --runtime python

Solution

1. Step 1: Identify correct Azure CLI syntax

   The correct command to create a Function App is az functionapp create with parameters --resource-group, --name, --storage-account, and --runtime.

2. Step 2: Compare options

   az functionapp create --resource-group mygroup --name myfuncapp --storage-account mystorage --runtime python matches the correct syntax. Options B, C, and D use incorrect commands or parameter names.

3. Final Answer:

   az functionapp create --resource-group mygroup --name myfuncapp --storage-account mystorage --runtime python -> Option D

4. Quick Check:

   Use az functionapp create with correct flags [OK]

Hint: Use 'az functionapp create' with correct flags [OK]

Common Mistakes:

• Using wrong command like 'az functionapp new'
• Mixing parameter names like '--group' instead of '--resource-group'
• Omitting required parameters

3. What will happen if you run this Azure CLI command?

az functionapp create --resource-group mygroup --name myfuncapp --storage-account mystorage --runtime node --runtime-version 14

medium

A. Fails because --runtime-version is not a valid parameter

B. Creates a Function App named myfuncapp with Node.js runtime version 14

C. Creates a Function App but ignores the runtime version

D. Creates a Function App with default runtime version

Solution

1. Step 1: Understand parameters in the command

   The command uses --runtime node and specifies --runtime-version 14, which is valid to set Node.js version 14.

2. Step 2: Check Azure CLI behavior

   Azure CLI supports --runtime-version to specify the runtime version, so the Function App will be created with Node.js 14.

3. Final Answer:

   Creates a Function App named myfuncapp with Node.js runtime version 14 -> Option B

4. Quick Check:

   Runtime and version flags create correct environment [OK]

Hint: Use --runtime and --runtime-version to specify environment [OK]

Common Mistakes:

• Thinking --runtime-version is invalid
• Assuming runtime version is ignored
• Confusing runtime with storage account

4. You tried to create a Function App with this command:

az functionapp create --resource-group mygroup --name myfuncapp --storage mystorage --runtime python

But it failed. What is the most likely cause?

medium

A. The parameter --storage is incorrect; it should be --storage-account

B. The runtime python is not supported

C. Resource group mygroup does not exist

D. Function App name myfuncapp is invalid

Solution

1. Step 1: Check command parameters

   The parameter for storage account must be --storage-account, not --storage.

2. Step 2: Validate other options

   Python runtime is supported, resource group existence is not confirmed but the error is about parameter, and the name looks valid.

3. Final Answer:

   The parameter --storage is incorrect; it should be --storage-account -> Option A

4. Quick Check:

   Use correct parameter names in CLI commands [OK]

Hint: Use --storage-account, not --storage [OK]

Common Mistakes:

• Using wrong parameter names
• Assuming runtime unsupported without checking
• Ignoring error messages about parameters

5. You want to create a Function App that runs Python code triggered every hour. Which two Azure services must you configure together to achieve this?

hard

A. Function App and Azure SQL Database

B. Function App and Azure Blob Storage

C. Function App and Timer Trigger

D. Function App and Azure Virtual Machine

Solution

1. Step 1: Identify the trigger for scheduled execution

   Azure Function Apps use triggers to start code. For hourly runs, a Timer Trigger is used.

2. Step 2: Understand service roles

   Blob Storage, Virtual Machines, and SQL Database are not used to schedule function runs but serve other purposes.

3. Final Answer:

   Function App and Timer Trigger -> Option C

4. Quick Check:

   Timer Trigger schedules Function App runs [OK]

Hint: Use Timer Trigger for scheduled Function Apps [OK]

Common Mistakes:

• Confusing storage or database with scheduling
• Thinking VM is needed for Function Apps
• Ignoring triggers in Function Apps
