10 free sample questions

Question 1 Design identity, governance, and monitoring solutions

An architect is planning diagnostic settings for a single Azure resource and wants to send resource logs to a Log Analytics workspace, an Azure Storage account, and an Event Hubs namespace at the same time, each as its own separate diagnostic setting. Per Azure Monitor's documented limit, how many diagnostic settings can this one resource have in total?

  1. An unlimited number of diagnostic settings
  2. Up to three diagnostic settings, one per destination type
  3. Up to five diagnostic settings
  4. One diagnostic setting only, covering all destinations combined
Show the answer and the explanation

Correct answer: C

Azure Monitor's documentation states that each resource can have up to five diagnostic settings, so the architect can create three separate settings (well within the limit) or more.

Question 2 Design data storage solutions

An architect needs an Azure SQL Database service tier that can scale a single database up to 128 TB of data storage, with that maximum not configurable by the customer. Which vCore service tier is documented as providing this?

  1. Standard (DTU-based)
  2. Business Critical
  3. General Purpose
  4. Hyperscale
Show the answer and the explanation

Correct answer: D

The documentation states that for Hyperscale, maximum data storage size is set to 128 TB and isn't configurable, matching the requirement exactly.

Question 3 Design business continuity solutions

An organization wants a centralized, policy-based Azure-native solution whose primary documented purpose is to protect its data and restore it when required, across workloads in Azure and beyond. Which service is documented for this purpose?

  1. Azure Policy
  2. Azure Cache for Redis
  3. Azure Backup
  4. Azure Site Recovery
Show the answer and the explanation

Correct answer: C

The documentation states that Azure Backup is a native Azure service that helps you protect your data and restore it when required, providing a centralized, policy-based solution to back up workloads — matching the requirement directly.

Question 4 Design infrastructure solutions

An organization wants a managed service to deploy, manage, and scale containerized Kubernetes applications at scale on Azure, without operating the Kubernetes control plane itself. Which service is documented as providing this?

  1. Azure Database Migration Service
  2. Azure Cache for Redis
  3. Azure Functions
  4. Azure Kubernetes Service (AKS)
Show the answer and the explanation

Correct answer: D

The documentation describes AKS as a managed Kubernetes service that simplifies deploying, managing, and scaling containerized applications that use Kubernetes — matching the requirement directly.

Question 5 Design identity, governance, and monitoring solutions

A company must stream Azure resource logs in near real time to a non-Microsoft SIEM solution hosted outside Azure. Which diagnostic setting destination should the architect recommend to route the logs to that external system?

  1. Event Hubs
  2. Partner solutions integration only
  3. Log Analytics workspace
  4. Azure Storage account
Show the answer and the explanation

Correct answer: A

The documentation states that the Event Hubs destination is used to stream data to external systems such as non-Microsoft SIEM solutions, which matches the requirement directly.

Question 6 Design data storage solutions

A SaaS provider runs many Azure SQL databases, one per customer, and each database has unpredictable, varying usage patterns that make it wasteful to size compute for every database individually. Which Azure SQL Database offering is documented as solving exactly this problem?

  1. Manually rescaling each database's compute tier on a schedule
  2. A dedicated Business Critical replica per customer
  3. Elastic pools
  4. A single database sized for peak load across all customers
Show the answer and the explanation

Correct answer: C

The documentation states that elastic pools solve this problem by ensuring that databases get the performance resources they need when they need them, within a predictable budget — the documented answer to per-customer databases with varying usage.

Question 7 Design business continuity solutions

A company runs business-critical VMware and Azure VMs and needs a solution that keeps replication frequency for Hyper-V workloads as low as 30 seconds, while meeting organizational RPO and RTO targets during zonal or regional outages. Which service is documented as providing this continuous replication and failover capability?

  1. Azure Backup
  2. Azure Policy
  3. Azure Site Recovery
  4. Azure Data Factory
Show the answer and the explanation

Correct answer: C

The documentation states that Site Recovery provides continuous replication for Azure VMs and VMware VMs, with replication frequency as low as 30 seconds for Hyper-V, and that it protects workloads against zonal and regional outages while meeting RPO and RTO — matching the scenario exactly.

Question 8 Design infrastructure solutions

A team wants to run short pieces of event-driven code, such as a scheduled data clean-up task, without provisioning or managing any servers, and with triggers and bindings that connect the code to other services with minimal extra code. Which compute service is documented as designed for this?

  1. Azure Site Recovery
  2. Azure Functions
  3. Azure Kubernetes Service (AKS)
  4. Azure Migrate
Show the answer and the explanation

Correct answer: B

The documentation describes Azure Functions as a serverless solution with event-driven triggers and bindings that connect functions to other services without extra code, and explicitly lists running a scheduled task to execute data clean-up code as a use case.

Question 9 Design identity, governance, and monitoring solutions

An architect describes Microsoft Entra Conditional Access to a customer as evaluating signals and then enforcing an outcome, for example requiring multifactor authentication before a user can reach an application. Which structure does the documentation use to describe how Conditional Access policies work at their simplest?

  1. If-then statements: if a user wants to access a resource, then they must complete an action
  2. A fixed sequence of security questions asked at every sign-in
  3. A static allow-list of approved IP addresses only
  4. Role-based approval workflows requiring administrator sign-off
Show the answer and the explanation

Correct answer: A

The documentation explicitly describes Conditional Access policies at their simplest as if-then statements, where wanting to access a resource triggers a required action such as multifactor authentication.

Question 10 Design data storage solutions

An architect must store blob data that is rarely accessed and can tolerate retrieval latency on the order of hours, at the lowest possible storage cost. Per Azure Blob Storage's documentation, this data must remain in the recommended access tier for a minimum period before an early-deletion charge applies. Which tier and minimum period are documented?

  1. Hot tier, no minimum period
  2. Archive tier, minimum 180 days
  3. Cool tier, minimum 30 days
  4. Cold tier, minimum 90 days
Show the answer and the explanation

Correct answer: B

The documentation describes the archive tier as an offline tier for rarely accessed data with flexible, hours-scale latency, and states that data must remain in the archive tier for at least 180 days or be subject to an early deletion charge.
