A single Azure virtual machine must read blobs from a storage account without storing any passwords, keys, or connection strings. The identity should be removed automatically if the VM is deleted. Which option should you use?
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
Storage account access key, because it is the simplest authentication method.
An access key is a secret and would have to be stored and managed on the VM or in configuration.
B
Best answer
System-assigned managed identity, because it is tied to that VM.
A system-assigned managed identity is attached directly to one Azure resource, such as a VM, and is automatically removed when that resource is deleted.
C
Distractor review
Shared access signature, because it always removes the need for identity management.
A SAS can limit access, but it is still a token you must generate and manage, and it is not tied to the VM itself.
D
Distractor review
User-assigned managed identity, because it is deleted automatically with the VM.
A user-assigned managed identity is reusable across resources and is not automatically deleted when one VM is removed.
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: System-assigned managed identity, because it is tied to that VM. — A system-assigned managed identity is the best choice for a single VM that needs to access Azure Storage without secrets. It is created for that VM, used for Azure AD-based authentication, and removed when the VM is deleted. That makes it ideal for reducing credential management and avoiding stored keys or passwords on the server. Why others are wrong: An access key is a long-lived secret, which is exactly what the scenario wants to avoid. A SAS token still has to be issued and managed separately. A user-assigned managed identity can be shared across resources, but it is not automatically deleted with a single VM.
