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

Azure Table Storage

Table Storage is cost-effective but lacks a latency SLA and is not globally distributed by default.

B

Best answer

Azure Cosmos DB with SQL API

Cosmos DB offers fast, predictable read latencies, global replication, and serverless capacity, ideal for session data that requires quick reads.

C

Distractor review

Azure Redis Cache

Redis Cache provides low latency but is not serverless; you must provision and pay for a cache tier, and it lacks built-in global distribution without additional configuration.

D

Distractor review

Azure Blob Storage

Blob Storage is optimized for large objects and throughput, not for small, frequent reads with low latency.

Common exam trap

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Technical deep dive

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

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?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: Azure Cosmos DB with SQL API — Azure Cosmos DB with SQL API provides low-latency reads, global distribution, and a serverless capacity mode, making it a great fit for session state with fast reads and rare writes. Table Storage has no latency SLA, Redis Cache is not serverless (though PaaS), and Blob Storage is not optimized for small, frequent read operations.
