VM-Web01 is connected to Subnet-Web in VNet-Prod. Users on the internet cannot access the website hosted on TCP port 443. You confirm that VM-Web01 has a public IP address and the web service is running. You need to allow inbound HTTPS traffic with the least administrative effort. What should you do?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Best answer

Add an inbound NSG rule allowing TCP 443.

This allows HTTPS traffic to reach the VM or subnet as required.

B

Distractor review

Create a user-defined route to the internet.

Routing is not the issue when the VM already has a public IP and the service is running.

C

Distractor review

Configure VNet peering with another virtual network.

Peering does not solve inbound internet access to the VM.

D

Distractor review

Create a private endpoint for VM-Web01.

Private endpoints are used for private access to Azure services, not for publishing a VM website to the internet.

Common exam trap

Common exam trap: usable hosts are not the same as total addresses

Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.

Technical deep dive

How to think about this question

Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.

KKey Concepts to Remember

  • CIDR notation defines the prefix length.
  • Block size helps identify subnet boundaries.
  • Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
  • The required host count determines the smallest suitable subnet.

TExam Day Tips

  • Write the block size before choosing the subnet.
  • Check whether the question asks for hosts, subnets or a specific address range.
  • Do not confuse /24, /25, /26 and /27 host counts.

Keep practising from the same exam bank, or move into a focused topic page if this question exposed a weak area.

Question 1

A route table contains these entries: 10.0.0.0/8 with next hop Virtual appliance, and 10.1.1.0/24 with next hop Virtual network gateway. Which next hop will Azure use for traffic to 10.1.1.5?

Question 2

You are deploying a stateless web application on Azure virtual machines. The solution must automatically add and remove instances based on CPU demand and allow all instances to be managed as one logical group. Which Azure compute feature should you deploy?

Question 3

You are deploying a Windows Server VM for an internal app. The VM must support Secure Boot and vTPM later, its OS disk must survive host moves, and the team wants the lowest-cost managed disk tier that still behaves like a normal writable OS disk. Which two choices should you make? Select two.

Question 4

You need to deploy several identical virtual machines and ensure that the failure of a single Azure host does not affect all of them. Which feature should you use?

Question 5

You need to connect VNet-Hub and VNet-Spoke so that resources in both virtual networks can communicate privately over the Microsoft backbone. Both virtual networks are in the same region. What should you configure?

Question 6

You need to create a storage account that provides the lowest-cost redundant storage for non-critical data and only needs protection against local disk or server failure within a single datacenter. Which redundancy option should you choose?

FAQ

Questions learners often ask

What does this AZ-104 question test?

CIDR notation defines the prefix length.

What is the correct answer to this question?

The correct answer is: Add an inbound NSG rule allowing TCP 443. — A network security group rule allowing inbound TCP 443 to the VM or subnet is the required control when the VM has a public IP and the service is listening. A route table does not open ports, VNet peering is unrelated to internet access in this scenario, and creating a private endpoint is for private access to Azure services rather than exposing a VM website.
