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.
An archive of legal documents is accessed only a few times each month, but when someone needs a document it must open immediately without a rehydration wait. Which access tier should be used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cool tier
The Cool tier is designed for data that is infrequently accessed but must be available immediately when needed, with a lower storage cost than Hot tier but higher access costs. Since the archive is accessed only a few times per month and requires instant retrieval without rehydration delay, Cool tier meets both requirements, whereas Archive tier would impose a rehydration wait of up to 15 hours.
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 tier
Why it's wrong here
Hot tier is optimized for frequent access, so it is usually more expensive than needed here.
✓
Cool tier
Why this is correct
Cool tier keeps data online and immediately available while reducing cost for infrequent access.
Clue confirmation
The clue word "immediately / without restart" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Archive tier
Why it's wrong here
Archive tier is offline and requires rehydration before access, which does not fit the requirement.
✗
Geo-redundant storage (GRS)
Why it's wrong here
GRS is a replication choice, not an access tier, so it does not solve access frequency.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the 'Archive' tier name with the use case of 'archival data' and overlook the critical requirement for immediate access, mistakenly choosing Archive tier despite its mandatory rehydration delay.
Detailed technical explanation
How to think about this question
Azure Blob Storage access tiers (Hot, Cool, Cold, Archive) are managed at the blob level and affect both pricing and latency; Cool tier offers near-real-time access with a first-byte latency of milliseconds, while Archive tier stores data offline and requires a tier change operation (rehydration) that can take from 1 to 15 hours depending on priority. The Cool tier also has a 30-day minimum storage charge, which aligns well with monthly access patterns, and its lower storage cost compared to Hot tier makes it ideal for infrequently accessed but immediately needed data like legal archives.
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.
