Zorluk: KolayAzure Storage Accounts, Blob, Disk, Files, and Storage Tiers

An administrator is reviewing the storage options and access tiers in Azure.

Which two of the following statements correctly describe the characteristics of Azure Blob Storage access tiers? (Select two.)

  1. The Hot access tier is optimized for storing data that is accessed or written frequently.Cevap
  2. The Archive access tier offers the lowest storage costs but requires data to be rehydrated to an online tier before it can be read.Cevap
  3. C
    The Cool access tier requires data to be rehydrated to the Hot tier before any read operations can occur.
  4. D
    The Archive access tier is designed to host active virtual machine operating system (OS) disks to reduce IaaS virtual machine costs.

Cevap

The correct statements are that the Hot access tier is optimized for storing data that is accessed or written frequently, and the Archive access tier offers the lowest storage costs but requires data to be rehydrated to an online tier before it can be read.
The correct statements are that the Hot access tier is designed for frequently accessed data and the Archive access tier requires data to be rehydrated to an online tier (Hot or Cool) before it can be read. The Hot tier has higher storage costs but lower access fees, which aligns with active data workloads. The Archive tier stores data offline at the lowest storage cost, but its data is not immediately readable until it undergoes rehydration.

Adım Adım Çözüm

1
Analyze the requirements for active vs. inactive data.
Identify that the Hot access tier is designed for active, frequently accessed data, while the Archive access tier is designed for rarely accessed data that can tolerate retrieval latency.
Understanding the design goals of each storage tier is necessary to identify correct descriptions of their access patterns.
2
Evaluate the access requirements and characteristics of the Cool and Archive tiers.
Confirm that the Cool tier is an online tier allowing immediate access (no rehydration needed), and the Archive tier is offline and requires rehydration before data can be read.
Differentiating online tiers (Hot, Cool) from offline tiers (Archive) helps rule out incorrect claims about rehydration requirements.
3
Compare Blob Storage tiers with VM Disk storage requirements.
Recognize that virtual machine OS disks require high-performance, low-latency persistent Disk Storage (IaaS), not offline Blob Storage tiers.
Distinguishing between block storage (Managed Disks) and object storage (Blob Storage) prevents misapplying storage tiers to VM OS disks.
