- A
Blob lifecycle management
Lifecycle management can automatically transition blobs between tiers based on age or other rules, reducing manual administration.
- B
Archive rehydration policy
Why wrong: Rehydration applies after data is already in Archive and needs to return to an online tier.
- C
Snapshot retention
Why wrong: Snapshots preserve point-in-time copies, but they do not automatically change blob access tiers.
- D
Storage account failover
Why wrong: Failover changes the active region and is unrelated to tier automation for individual blobs.

AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A monthly report file must automatically move to a cheaper online tier after 90 days in Azure Blob Storage. Which feature should the administrator configure?
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
✓
Blob lifecycle management
Blob lifecycle management is the correct feature because it allows administrators to define rules that automatically transition blobs to a cheaper access tier (e.g., from Hot to Cool) after a specified number of days. This policy operates at the storage account or container level and can move data to the Cool or Archive tier based on age, meeting the requirement of moving the report file after 90 days without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Blob lifecycle management
Why this is correct
Lifecycle management can automatically transition blobs between tiers based on age or other rules, reducing manual administration.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Archive rehydration policy
Why it's wrong here
Rehydration applies after data is already in Archive and needs to return to an online tier.
When this WOULD be correct
An administrator needs to retrieve archived data for immediate access and must configure the priority and duration of the rehydration process.
- ✗
Snapshot retention
Why it's wrong here
Snapshots preserve point-in-time copies, but they do not automatically change blob access tiers.
When this WOULD be correct
A question asking how to automatically delete old snapshots of blobs after a specified number of days to reduce storage costs would have snapshot retention as the correct answer.
- ✗
Storage account failover
Why it's wrong here
Failover changes the active region and is unrelated to tier automation for individual blobs.
When this WOULD be correct
An administrator needs to ensure that if the primary region becomes unavailable, the storage account automatically switches to a paired secondary region to maintain availability. In that scenario, configuring storage account failover would be the correct answer.
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.
✓Blob lifecycle managementCorrect answer▾
Why this is correct
Lifecycle management can automatically transition blobs between tiers based on age or other rules, reducing manual administration.
✗Archive rehydration policyWrong answer — click to see why▾
Why this is wrong here
Archive rehydration policy is used to change the access tier of a blob from Archive to a hot or cool tier, not to automatically move blobs to a cheaper tier after a set period.
★ When this WOULD be the correct answer
An administrator needs to retrieve archived data for immediate access and must configure the priority and duration of the rehydration process.
Why candidates choose this
Candidates may confuse 'rehydration' (changing from archive to hot/cool) with 'lifecycle management' (moving between tiers over time), as both involve tier changes.
✗Snapshot retentionWrong answer — click to see why▾
Why this is wrong here
Snapshot retention manages the lifecycle of blob snapshots, not the tiering of the base blob itself. The question requires moving the base blob to a cheaper tier after 90 days, which is not controlled by snapshot retention.
★ When this WOULD be the correct answer
A question asking how to automatically delete old snapshots of blobs after a specified number of days to reduce storage costs would have snapshot retention as the correct answer.
Why candidates choose this
Candidates may confuse snapshot retention with lifecycle management because both involve time-based policies, but snapshot retention specifically targets snapshots, not the base blob's tier.
✗Storage account failoverWrong answer — click to see why▾
Why this is wrong here
Storage account failover is a disaster recovery feature that switches the primary region to a secondary region, not a data tiering or cost optimization feature. It does not move blobs to cheaper tiers based on age.
★ When this WOULD be the correct answer
An administrator needs to ensure that if the primary region becomes unavailable, the storage account automatically switches to a paired secondary region to maintain availability. In that scenario, configuring storage account failover would be the correct answer.
Why candidates choose this
Candidates may confuse failover with lifecycle management because both involve automatic actions on storage accounts, but failover is about regional redundancy, not cost-efficient data movement.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse 'archive rehydration' (which moves data from Archive to a cheaper tier? No, it moves to an online tier) with lifecycle management, or think snapshot retention can handle tiering, but snapshots are only for versioning and recovery, not cost-based tier transitions.
Detailed technical explanation
How to think about this question
Blob lifecycle management uses XML-based policy rules defined in JSON or XML, evaluated every 24 hours by Azure Storage. The policy can include filters for blob type (block or append), prefix matching, and actions like 'tierToCool' or 'tierToArchive' after a specified number of days since creation or last modification. A real-world scenario is automatically moving logs from Hot to Cool after 30 days and then to Archive after 180 days to optimize costs, with the rule ensuring no manual oversight is needed.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
Quick reference
Azure Blob Storage Tier Comparison
| Tier | Storage Cost | Retrieval Cost | Latency | Use Case |
|---|---|---|---|---|
| Hot | Highest | Lowest | Immediate | Active data, frequent reads |
| Cool | Lower | Higher | Immediate | Data accessed < once / month |
| Cold | Lower still | Higher | Immediate | Data accessed < once / quarter |
| Archive | Lowest | Highest + rehydration delay | Hours | Long-term compliance retention |
