Designing and Implementing Microsoft Azure Networking Solutions — Question 92

You have an Azure subscription.

You plan to deploy an app named App1 that will be accessed by using Azure Application Gateway.

You need to deploy the application gateway for App1.

What should you create first?

Answer options

• A. a user-assigned managed identity
• B. a subnet
• C. an X.509 certificate
• D. an Azure Web Application Firewall (WAF) policy

Correct answer: B

Explanation

The correct answer is B, a subnet, because an Azure Application Gateway must be deployed within a virtual network that contains at least one subnet. Options A, C, and D are not prerequisites for creating an application gateway and do not provide the necessary network infrastructure needed for deployment.
