The Hot tier is intended for data that is accessed frequently.
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
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?
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.
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
Two application components need asynchronous communication so messages can wait until the receiver processes them. Which service is a simple fit?
Reveal answer and explanation
Correct answer: A. Azure Queue Storage
Azure Queue Storage provides simple message queues for asynchronous communication.
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
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?
Reveal answer and explanation
Correct answer: A. Azure Functions

Reveal answer and explanation
Correct answer: A. Virtual Machine Scale Sets
Virtual Machine Scale Sets manage and scale groups of identical VMs.
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
A web app has VMs in the same region and needs Layer 4 distribution of inbound TCP traffic. Which service is the basic fit?
Reveal answer and explanation
Correct answer: A. Azure Load Balancer
Azure Load Balancer distributes Layer 4 TCP and UDP traffic.
