Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A developer wants to give one Azure VM access to Azure Storage now, and that identity should be removed automatically if the VM is deleted. Which identity type should the administrator assign?
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
Distractor review
A user-assigned managed identity
A user-assigned managed identity can be shared across multiple resources and remains independent of any single VM. That makes it useful for reuse, but it does not automatically disappear when one VM is deleted. This does not match the requirement for VM-tied lifecycle behavior.
B
Best answer
A system-assigned managed identity
A system-assigned managed identity is attached directly to one Azure resource, such as a VM, and Azure manages its lifecycle with that resource. If the VM is deleted, the identity is also removed automatically. This makes it the right choice when the identity should exist only for that VM.
C
Distractor review
A storage account SAS token
A SAS token is a signed access string for storage, not an Azure identity. It can expire, but it does not provide a managed identity lifecycle tied to the VM. It would also have to be stored or distributed somewhere, which is not the desired model here.
D
Distractor review
An NSG service tag
A service tag is used in network security rules to represent groups of IP addresses. It does not grant the VM access to Azure Storage through identity-based authentication and does not have a lifecycle tied to the VM. It is the wrong feature for this requirement.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

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?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: A system-assigned managed identity — A system-assigned managed identity is the right choice because it is created for one specific Azure resource and is deleted when that resource is deleted. It lets the VM authenticate to Azure Storage without credentials and keeps the lifecycle tightly coupled to the VM. That combination matches both the security and lifecycle requirements in the scenario. Why others are wrong: A user-assigned identity is reusable and does not disappear with one VM. A SAS token is a storage permission mechanism, not an Azure identity. An NSG service tag is purely for network filtering. The requirement is for an identity that follows the VM lifecycle automatically, which is exactly what system-assigned managed identity does.
