B--plan Premium

C--consumption-plan-location eastus

D--plan Dedicated

💡 Hint

Common Mistakes

Using --plan Premium or --plan Dedicated instead of --consumption-plan-location.

Omitting the plan parameter entirely.

Consumption plan is specified with --consumption-plan-location eastus to enable consumption-based pricing.

💡 Hint

Common Mistakes

Using Consumption plan parameters instead of Premium.

Selecting Basic or Free which are not valid for premium features.

The Premium plan is specified by using --plan myPremiumPlan to enable premium features and pricing.

Fix the error in the Azure CLI command to deploy a function app with consumption pricing.

Azure

az functionapp create --resource-group myResourceGroup --name myFuncApp --storage-account mystorage [1]

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

💡 Hint

Common Mistakes

Using --plan Premium or --plan Dedicated causes deployment errors.

Leaving the parameter empty.

The consumption plan must be specified as --consumption-plan-location eastus to deploy with consumption pricing.

Fill both blanks to configure an Azure Function App with Premium plan and enable VNET integration.

Azure

az functionapp create --resource-group myResourceGroup --name myFuncApp --storage-account mystorage --plan [1] --vnet-route-all-enabled [2]

💡 Hint

Common Mistakes

Using Consumption parameters which do not support VNET integration.

Setting VNET routing to false disables the feature.

Use myPremiumPlan for the plan to enable premium features and true to enable VNET integration routing.

Fill all three blanks to create a function app with consumption plan, specify runtime as Python, and enable application insights.

Azure

az functionapp create --resource-group myResourceGroup --name myFuncApp --storage-account mystorage --consumption-plan-location [1] --runtime [2] --application-insights [3]

💡 Hint

Common Mistakes

Using Premium plan when consumption is required.

Specifying wrong runtime names.

Not enabling application insights.

Use eastus for the consumption plan location, python for the runtime, and myAppInsights to enable application insights monitoring.

Practice

1. Which Azure Function pricing plan charges you only when your function runs, making it ideal for infrequent tasks?

easy

A. Dedicated App Service plan

B. Consumption plan

C. Premium plan

D. Enterprise plan

Solution

1. Step 1: Understand pricing models

   The Consumption plan charges based on actual function executions, so you pay only when your code runs.

2. Step 2: Compare with other plans

   The Premium plan and Dedicated plans have fixed costs regardless of usage, making them less ideal for infrequent tasks.

3. Final Answer:

   Consumption plan -> Option B

4. Quick Check:

   Pay per use = Consumption plan [OK]

Hint: Pay only when running = Consumption plan [OK]

Common Mistakes:

• Confusing Premium plan with Consumption plan
• Thinking Dedicated plan charges per use
• Assuming Enterprise plan is standard for functions

2. Which of the following is the correct way to describe the Premium plan pricing for Azure Functions?

easy

A. Fixed cost plus charges based on usage

B. You pay only when the function runs, no fixed cost

C. Free for all usage levels

D. Charges based on number of users

Solution

1. Step 1: Identify Premium plan pricing

   The Premium plan has a fixed monthly cost plus additional charges based on how much you use it.

2. Step 2: Eliminate incorrect options

   Consumption plan is pay-per-use only, so You pay only when the function runs, no fixed cost is wrong. There is no free unlimited usage or user-based pricing.

3. Final Answer:

   Fixed cost plus charges based on usage -> Option A

4. Quick Check:

   Premium = fixed + usage cost [OK]

Hint: Premium = fixed cost plus usage charges [OK]

Common Mistakes:

• Confusing Premium with Consumption plan pricing
• Thinking Premium plan is free
• Assuming pricing depends on users

3. You have an Azure Function running on the Consumption plan that executes 1 million times a month. Which statement best describes your billing?

medium

A. You pay a fixed fee plus a small charge per execution.

B. You pay a fixed monthly fee regardless of executions.

C. You pay only for the 1 million executions plus resource usage.

D. You pay nothing because Consumption plan is free.

Solution

1. Step 1: Understand Consumption plan billing

   Consumption plan charges based on the number of executions and resource consumption, no fixed fee.

2. Step 2: Analyze options

   You pay a fixed monthly fee regardless of executions. and C mention fixed fees which do not apply to Consumption plan. You pay nothing because Consumption plan is free. is incorrect because Consumption plan is not free.

3. Final Answer:

   You pay only for the 1 million executions plus resource usage. -> Option C

4. Quick Check:

   Consumption = pay per execution [OK]

Hint: Consumption plan charges per execution only [OK]

Common Mistakes:

• Assuming fixed monthly fee on Consumption plan
• Thinking Consumption plan is free
• Mixing Premium plan billing with Consumption

4. You deployed an Azure Function on the Premium plan but noticed unexpectedly high costs. What is a likely cause?

medium

A. Premium plan has a fixed cost plus usage, so fixed cost adds even if usage is low.

B. Premium plan is free for the first 1 million executions, so costs should be zero.

C. You forgot to enable the Consumption plan, so you are charged double.

D. You are charged only when the function runs, so high usage caused high cost.

Solution

1. Step 1: Understand Premium plan cost structure

   Premium plan includes a fixed monthly cost plus charges based on usage.

2. Step 2: Identify cause of high costs

   Even if usage is low, the fixed cost applies, which can cause unexpectedly high bills.

3. Final Answer:

   Premium plan has a fixed cost plus usage, so fixed cost adds even if usage is low. -> Option A

4. Quick Check:

   Premium fixed cost causes base charges [OK]

Hint: Premium plan always has fixed cost component [OK]

Common Mistakes:

• Thinking Premium charges only on usage
• Confusing Consumption plan with Premium
• Assuming Premium plan is free for some executions

5. You expect your Azure Function to have steady, high traffic with occasional spikes. Which plan should you choose to optimize cost and performance?

hard

A. Free tier, because it handles high traffic without cost

B. Consumption plan, because it charges only when functions run

C. Dedicated App Service plan, because it has no scaling limits

D. Premium plan, because it offers pre-warmed instances and scales smoothly

Solution

1. Step 1: Analyze workload pattern

   Steady high traffic with spikes needs consistent performance and quick scaling.

2. Step 2: Match plan features

   Premium plan provides pre-warmed instances to avoid cold starts and scales smoothly, fitting this pattern well.

3. Step 3: Eliminate other options

   Consumption plan may have cold starts causing delays. Dedicated plan is costly and less flexible. Free tier cannot handle high traffic.

4. Final Answer:

   Premium plan, because it offers pre-warmed instances and scales smoothly -> Option D

5. Quick Check:

   Steady high traffic = Premium plan [OK]

Hint: Steady high traffic? Choose Premium for performance [OK]

Common Mistakes:

• Choosing Consumption plan despite cold start delays
• Assuming Dedicated plan is best for all cases
• Thinking Free tier supports high traffic
