AZ-104 Implement and Manage Storage Practice Question

This AZ-104 practice question tests your understanding of implement and manage storage. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.

You plan to store backup files that are written once per week and are rarely accessed except during an audit. The company wants the lowest storage cost but still needs online access within hours, not days. Which blob access tier should you choose?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Cool

The Cool tier is the correct choice because it is designed for data that is infrequently accessed and stored for at least 30 days, offering lower storage costs than Hot while still providing millisecond latency for online access. Since backups are written once per week and rarely accessed except during an audit, Cool tier meets the requirement of online access within hours at the lowest storage cost among the online tiers.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Hot

    Why it's wrong here

    Hot is optimized for frequent access and usually costs more for storage.

    When this WOULD be correct

    A question where data is accessed frequently (e.g., multiple times per day) and low latency is critical, such as a production database backup that is restored often. The requirement would be lowest latency, not lowest cost.

  • Cool

    Why this is correct

    Cool is appropriate for infrequently accessed data that still needs to remain online.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Archive

    Why it's wrong here

    Archive has the lowest storage cost but requires rehydration and is not online for normal access.

    When this WOULD be correct

    If the question stated that data is rarely accessed and retrieval within 24-48 hours is acceptable, or if the requirement was lowest storage cost with no specific online access time constraint, Archive would be correct.

  • Premium

    Why it's wrong here

    Premium is for workloads requiring low latency and high IOPS, not low-cost backup retention.

    When this WOULD be correct

    A question where the workload requires consistent, low-latency access (e.g., <10ms) for frequently updated data, such as an interactive application's active dataset, and cost is not the primary concern.

Option-by-option analysis

Why each answer is right or wrong

Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.

CoolCorrect answer

Why this is correct

Cool is appropriate for infrequently accessed data that still needs to remain online.

HotWrong answer — click to see why

Why this is wrong here

Hot tier is designed for frequently accessed data with the lowest access latency, but it has the highest storage cost. The scenario requires lowest storage cost and only occasional access, making Hot unnecessarily expensive.

★ When this WOULD be the correct answer

A question where data is accessed frequently (e.g., multiple times per day) and low latency is critical, such as a production database backup that is restored often. The requirement would be lowest latency, not lowest cost.

Why candidates choose this

Candidates may assume 'online access within hours' means Hot is needed, but Cool also provides online access within hours at lower cost. They overlook that Hot is for frequent access, not just online availability.

ArchiveWrong answer — click to see why

Why this is wrong here

Archive tier has the lowest storage cost but retrieval times can take up to 15 hours, which does not meet the requirement of online access within hours.

★ When this WOULD be the correct answer

If the question stated that data is rarely accessed and retrieval within 24-48 hours is acceptable, or if the requirement was lowest storage cost with no specific online access time constraint, Archive would be correct.

Why candidates choose this

Candidates see 'lowest storage cost' and 'rarely accessed' and immediately think Archive, overlooking the 'online access within hours' constraint that Archive cannot satisfy.

PremiumWrong answer — click to see why

Why this is wrong here

Premium tier is designed for low-latency, high-performance workloads and has the highest cost, which contradicts the requirement for lowest storage cost. The scenario does not need sub-second access, only online access within hours.

★ When this WOULD be the correct answer

A question where the workload requires consistent, low-latency access (e.g., <10ms) for frequently updated data, such as an interactive application's active dataset, and cost is not the primary concern.

Why candidates choose this

Candidates may assume 'Premium' implies better overall performance and reliability, not realizing it is optimized for specific high-cost, low-latency scenarios and is not suitable for cost-sensitive backup storage.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often choose Archive for the lowest storage cost without considering the rehydration time requirement, mistakenly assuming 'online access within hours' is satisfied by Archive's standard rehydration priority of up to 15 hours.

Detailed technical explanation

How to think about this question

Under the hood, Azure Blob Storage access tiers (Hot, Cool, Cold, Archive) use different pricing models: Hot has higher storage cost but no minimum retention period, Cool has lower storage cost with a 30-day minimum retention charge, and Archive has the lowest storage cost but requires a rehydration operation (changing the blob tier to Hot or Cool) before access, which can take from 1 to 15 hours depending on the rehydration priority. In a real-world scenario, if an auditor needs access to a backup file, the Cool tier allows immediate download without any delay, whereas Archive would require planning ahead for the rehydration time.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
