You are developing a solution that stores large media files in Azure Blob Storage. Users access these files frequently for the first 30 days, then rarely afterwards. To optimize costs, you need to automatically move blobs to a cooler tier after 30 days of creation. Which Azure feature 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

Best answer

Lifecycle management policies

Correct. Lifecycle management policies automate tier transitions based on age, optimizing cost.

B

Distractor review

Blob inventory

Incorrect. Blob inventory provides a report of blobs but does not automate tier changes.

C

Distractor review

Change feed

Incorrect. Change feed logs blob creation and modification events but does not manage tier transitions.

D

Distractor review

Immutable storage

Incorrect. Immutable storage prevents modification or deletion of blobs but does not handle tiering.

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: Lifecycle management policies — Azure Blob Storage lifecycle management policies allow you to define rules that automatically transition blobs to a cooler storage tier (e.g., from Hot to Cool or Archive) based on the age of the blob. This is the correct feature for cost optimization based on access patterns. Blob Inventory provides a list of blobs, Change Feed logs changes, and Immutable Storage prevents deletion or modification.
