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

Mount an Azure Files share as a volume

Correct. Azure Files provides SMB file shares that can be mounted as volumes in ACI, offering persistent storage at low cost with minimal complexity.

B

Distractor review

Store logs in Azure Container Registry

Incorrect. Azure Container Registry is for storing and managing container images, not for runtime log storage.

C

Distractor review

Use a Docker volume in the container

Incorrect. Docker volumes are not directly supported in Azure Container Instances without an orchestration platform like Kubernetes.

D

Distractor review

Pass log path via an environment variable

Incorrect. Environment variables cannot persist data; they are only used for configuration and are lost when the container restarts.

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

An application stores customer invoices in Azure Blob Storage. Deleted blobs must be recoverable for 14 days. What should be enabled?

Question 2

You are deploying a containerized application to Azure Container Instances. The application requires a custom domain name and SSL/TLS termination. You need to configure these features. Which resource should you create alongside the container group?

Question 3

A developer needs to run a Kusto query against application request data to identify 95th percentile latency by operation. Where should the query be run? The architecture review board prefers a managed AWS-native control.

Question 4

You are developing a web app that authenticates users via Microsoft Entra ID. The app needs to read the user's profile and send emails on their behalf. You want to minimize user consent prompts. Which OAuth 2.0 grant type should you use?

Question 5

You are developing an Azure Function that processes messages from an Azure Service Bus queue. The function uses a Service Bus queue trigger and runs on a Consumption Plan. The queue receives a high volume of messages in bursts. You need to ensure that the function scales out to handle the load but does not exceed 10 concurrent instances. Which configuration should you apply?

Question 6

You are monitoring an Azure App Service using Application Insights. You notice that the server response time is high for certain requests. You need to drill down to see which external dependencies (like databases or APIs) are causing the delay. Which Application Insights feature should you use?

FAQ

Questions learners often ask

What does this AZ-204 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: Mount an Azure Files share as a volume — Azure Container Instances supports mounting Azure Files shares as volumes, providing persistent storage that survives container restarts and can be accessed via the file system. Azure Container Registry stores container images, not runtime data. Docker volumes are not natively supported in ACI without an orchestrator. Environment variables are ephemeral and lost on restart.
