Questions

Question 51

Single answerStorage tiers
A team stores images that are accessed frequently by customers. Which Blob Storage access tier is the best initial choice?
  • A. Hot
  • B. Cool
  • C. Archive
  • D. Offline
Reveal answer and explanation
Correct answer: A. Hot
The Hot tier is intended for data that is accessed frequently.
Why the others are wrong: Cool and Archive are designed for less frequently accessed data; Offline is not a Blob access tier.

Objective: Storage tiers.

Question 52

Single answerArchive data
A legal archive must be kept for years and will rarely be read. Lowest storage cost is more important than immediate access. Which tier fits best?
  • A. Archive
  • B. Hot
  • C. Premium file share
  • D. Queue Storage
Reveal answer and explanation
Correct answer: A. Archive
Archive is optimized for rarely accessed blob data with the lowest storage cost and higher retrieval latency.
Why the others are wrong: Hot costs more for frequent access, Premium files are for high-performance file shares, and queues store messages.

Objective: Archive data.

Question 53

Single answerMessaging
Two application components need asynchronous communication so messages can wait until the receiver processes them. Which service is a simple fit?
  • A. Azure Queue Storage
  • B. Azure DNS
  • C. Azure Bastion
  • D. Azure Policy
Reveal answer and explanation
Correct answer: A. Azure Queue Storage
Azure Queue Storage provides simple message queues for asynchronous communication.
Why the others are wrong: DNS, Bastion, and Policy do not provide queue-based application messaging.

Objective: Messaging.

Question 54

Single answerServerless
A small task should run when a file is uploaded to storage, and the team does not want to manage servers. Which compute option fits?
  • A. Azure Functions
  • B. Azure Virtual Machines
  • C. Azure VMware Solution
  • D. Azure Dedicated Host
Reveal answer and explanation
Correct answer: A. Azure Functions
Azure Functions is a serverless compute service that can run code in response to events.
Why the others are wrong: VMs, VMware Solution, and Dedicated Host require more infrastructure management.

Objective: Serverless.

Question 55

Single answerContainers
A team wants to run a container quickly without managing Kubernetes orchestration. Which service is the simplest option?
  • A. Azure Container Instances
  • B. Azure Kubernetes Service
  • C. Azure Virtual Desktop
  • D. Azure ExpressRoute
Reveal answer and explanation
Correct answer: A. Azure Container Instances
Azure Container Instances runs containers without requiring you to manage servers or a Kubernetes cluster.
Why the others are wrong: AKS is for orchestrated Kubernetes, Virtual Desktop provides desktops, and ExpressRoute provides private connectivity.

Objective: Containers.

Question 56

Single answerKubernetes
A company wants a managed Kubernetes control plane for containerized microservices. Which Azure service should it use?
  • A. Azure Kubernetes Service
  • B. Azure App Configuration
  • C. Azure Files
  • D. Azure Advisor
Reveal answer and explanation
Correct answer: A. Azure Kubernetes Service
Azure Kubernetes Service is Azure’s managed Kubernetes service.
Why the others are wrong: The other services do not provide Kubernetes orchestration.

Objective: Kubernetes.

Question 57

Single answerScale sets
An application uses many identical virtual machines and must automatically scale out and in based on demand. Which Azure compute feature fits?
  • A. Virtual Machine Scale Sets
  • B. Availability sets only
  • C. Azure DNS zones
  • D. Storage account lifecycle management
Reveal answer and explanation
Correct answer: A. Virtual Machine Scale Sets
Virtual Machine Scale Sets manage and scale groups of identical VMs.
Why the others are wrong: Availability sets improve placement availability but do not provide automatic horizontal scaling by themselves.

Objective: Scale sets.

Question 58

Single answerLoad balancing
A web app has VMs in the same region and needs Layer 4 distribution of inbound TCP traffic. Which service is the basic fit?
  • A. Azure Load Balancer
  • B. Azure Key Vault
  • C. Azure Policy
  • D. Azure TCO Calculator
Reveal answer and explanation
Correct answer: A. Azure Load Balancer
Azure Load Balancer distributes Layer 4 TCP and UDP traffic.
Why the others are wrong: Key Vault manages secrets, Policy enforces rules, and TCO estimates migration savings.

Objective: Load balancing.

Question 59

Single answerHTTP routing
A web application needs path-based routing and web application firewall capabilities. Which service is most appropriate?
  • A. Azure Application Gateway
  • B. Azure Queue Storage
  • C. Azure Files
  • D. Azure Service Health
Reveal answer and explanation
Correct answer: A. Azure Application Gateway
Application Gateway is a Layer 7 load balancer that supports URL path-based routing and WAF integration.
Why the others are wrong: The other options do not provide Layer 7 web routing with WAF.

Objective: HTTP routing.

Question 60

Single answerNoSQL database
A globally distributed application needs a fully managed NoSQL database with multiple consistency options. Which service should be considered?
  • A. Azure Cosmos DB
  • B. Azure SQL Database only
  • C. Azure Disk Storage
  • D. Azure Bastion
Reveal answer and explanation
