Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A web app running in Azure App Service must upload images to a blob container without storing any account keys, passwords, or connection strings in configuration. The app uses only one Azure resource. What should the administrator configure?
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
A system-assigned managed identity on the App Service and an Azure RBAC role on the storage account.
A system-assigned managed identity is ideal when one Azure resource needs to access storage without secrets. The identity is created and deleted with the App Service, and RBAC can grant only the storage permissions required. This removes the need to embed keys or connection strings and aligns with credential-free application access.
B
Distractor review
The storage account key, because it is the simplest way to authenticate an application securely.
The account key works, but it is a shared secret that must be protected and rotated. The requirement explicitly says not to store keys or secrets.
C
Distractor review
A shared access signature embedded in the app settings, because SAS is the same as managed identity.
A SAS token can reduce scope, but it is still a secret that must be stored and managed. It is not the same as a managed identity and does not meet the no-secrets requirement.
D
Distractor review
An anonymous public container with write access disabled on the account.
Public access does not provide authenticated write access for a web application. It also weakens security far beyond what the scenario allows.
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 on the App Service and an Azure RBAC role on the storage account. — A system-assigned managed identity is the most appropriate solution because it lets the App Service authenticate to Azure Storage without storing any credentials. You then grant the identity a storage data role, such as Storage Blob Data Contributor, at the smallest suitable scope. This is the standard Azure pattern for secretless access from one Azure resource to another. Why others are wrong: The account key and SAS both involve secrets, which the scenario prohibits. A public container is not a secure or appropriate method for application writes. Managed identity is specifically designed to replace embedded credentials for Azure-to-Azure access and is the best operational and security choice here.
