AZ-204 Practice Question: Blob lifecycle management for automatic tiering…

This AZ-204 practice question tests your understanding of blob lifecycle management for automatic tiering…. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: blob Storage lifecycle management policy. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Audit logs are written daily as block blobs to an Azure Storage account. Logs older than 90 days must move to Cool tier automatically; logs older than 365 days must be deleted. The developer wants to implement this with no custom code and no recurring jobs. What is the correct solution?

Audit logs are written daily as block blobs to an Azure Storage account. Logs older than 90 days must move to Cool tier automatically; logs older than 365 days must be deleted. The developer wants to implement this with no custom code and no recurring jobs. What is the correct solution?

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

Configure a Logic App with a Recurrence trigger to enumerate and process blobs weekly

Like the Function approach, this requires external orchestration and custom logic. Lifecycle management is the native, zero-code alternative that runs on the storage service itself.

B

Best answer

Create a lifecycle management policy with two rules: tier to Cool after 90 days and delete after 365 days

Lifecycle management policies are evaluated nightly by Azure. The two rules (tier after 90 days, delete after 365 days) are declared in JSON and applied to blobs matching the prefix filter. No code is required — the storage service acts on them automatically.

C

Distractor review

Write an Azure Function with a Timer trigger that lists all blobs, checks last-modified dates, and tiers or deletes them via the SDK

This approach works but introduces unnecessary complexity — custom code, a Function App, and trigger configuration to maintain. Lifecycle management policies accomplish exactly this without any code.

D

Distractor review

Enable Blob versioning and set a version retention policy of 365 days

Blob versioning retains deleted or overwritten versions for a retention period. It does not move blobs between tiers based on age, and it does not delete blobs after 365 days based on their creation time.

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

Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

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?

Blob Storage lifecycle management policy

What is the correct answer to this question?

The correct answer is: Create a lifecycle management policy with two rules: tier to Cool after 90 days and delete after 365 days — Azure Blob Storage lifecycle management policies are declarative rules evaluated daily by the storage service. A policy can tier blobs to Cool or Archive based on last-modified age and delete them after a configurable threshold. The service executes the rules automatically — no code, no jobs, no timers required. This is the purpose-built solution for automated blob tiering and expiration.
