AZ-104 Monitor and Maintain Azure Resources Practice Question
This AZ-104 practice question tests your understanding of monitor and maintain azure resources. 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.
Exhibit
Azure Backup policy
- Schedule: Daily at 01:00
- Retain instant recovery snapshots: 2 days
- Retain daily backup points: 7 days
- Retain weekly backup points: Not configured
Business requirement: Keep daily backups for 30 days
Based on the exhibit, what should the administrator change if the business wants backups to be kept for 30 days instead of 7 days?
Exhibit
Azure Backup policy
- Schedule: Daily at 01:00
- Retain instant recovery snapshots: 2 days
- Retain daily backup points: 7 days
- Retain weekly backup points: Not configured
Business requirement: Keep daily backups for 30 days
A
Change the backup schedule from daily to hourly.
Why wrong: Changing frequency does not increase the retention period for existing daily recovery points.
B
Increase the retain daily backup points setting to 30 days.
The requirement is about how long daily recovery points are kept, not how often backups run. The policy setting that controls that is the retention value for daily backup points. Updating it from 7 days to 30 days keeps the restore points available for the required period while leaving the backup schedule unchanged.
C
Increase the instant recovery snapshot retention to 30 days.
Why wrong: Instant recovery snapshots are short-lived local snapshots and are not the same as long-term backup retention.
D
Enable a CanNotDelete lock on the Recovery Services vault.
Why wrong: A lock protects the vault from deletion, but it does not change how long backup restore points are retained.

Correct answer & explanation
✓
Increase the retain daily backup points setting to 30 days.
The backup retention policy in Azure Backup is configured via the 'Retain daily backup points' setting, which specifies how many days daily recovery points are kept. To change retention from 7 to 30 days, the administrator must increase this value to 30. This directly controls the lifespan of daily backups in the Recovery Services vault.
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.
✗
Change the backup schedule from daily to hourly.
Why it's wrong here
Changing frequency does not increase the retention period for existing daily recovery points.
When this WOULD be correct
If the business requirement were to reduce the maximum potential data loss (recovery point objective) from 24 hours to 1 hour, then changing the backup schedule from daily to hourly would be correct.
✓
Increase the retain daily backup points setting to 30 days.
Why this is correct
The requirement is about how long daily recovery points are kept, not how often backups run. The policy setting that controls that is the retention value for daily backup points. Updating it from 7 days to 30 days keeps the restore points available for the required period while leaving the backup schedule unchanged.

✗
Increase the instant recovery snapshot retention to 30 days.
Why it's wrong here
Instant recovery snapshots are short-lived local snapshots and are not the same as long-term backup retention.
When this WOULD be correct
This option would be correct if the question asked: 'The administrator wants to ensure that instant restore snapshots are available for 30 days to speed up recovery.' In that case, increasing instant recovery snapshot retention to 30 days would be the appropriate action.
✗
Enable a CanNotDelete lock on the Recovery Services vault.
Why it's wrong here
A lock protects the vault from deletion, but it does not change how long backup restore points are retained.
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.
✓Increase the retain daily backup points setting to 30 days.Correct answer▾
Why this is correct
The requirement is about how long daily recovery points are kept, not how often backups run. The policy setting that controls that is the retention value for daily backup points. Updating it from 7 days to 30 days keeps the restore points available for the required period while leaving the backup schedule unchanged.
✗Change the backup schedule from daily to hourly.Wrong answer — click to see why▾
Why this is wrong here
Changing the backup schedule from daily to hourly increases backup frequency, not retention duration. The question asks to keep backups for 30 days instead of 7 days, which is a retention setting, not a scheduling change.
★ When this WOULD be the correct answer
If the business requirement were to reduce the maximum potential data loss (recovery point objective) from 24 hours to 1 hour, then changing the backup schedule from daily to hourly would be correct.
Why candidates choose this
Candidates may confuse backup frequency with retention, thinking more frequent backups automatically mean longer retention, or they may misread the question as needing more backup copies rather than longer storage duration.
✗Increase the instant recovery snapshot retention to 30 days.Wrong answer — click to see why▾
Why this is wrong here
The instant recovery snapshot retention setting controls how long snapshots are kept for immediate restores, not the overall backup retention period. The question asks for keeping backups for 30 days, which is managed by the retention policy (e.g., retain daily backup points).
★ When this WOULD be the correct answer
This option would be correct if the question asked: 'The administrator wants to ensure that instant restore snapshots are available for 30 days to speed up recovery.' In that case, increasing instant recovery snapshot retention to 30 days would be the appropriate action.
Why candidates choose this
Candidates may confuse 'instant recovery snapshot retention' with overall backup retention, thinking that increasing snapshot retention extends the total backup retention period, or they may not understand the difference between snapshot retention and backup point retention.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing 'instant recovery snapshot retention' (short-term local snapshots) with 'daily backup point retention' (long-term vault retention), leading candidates to incorrectly select option C.
Detailed technical explanation
How to think about this question
Azure Backup uses a tiered retention model: instant recovery snapshots (typically kept for 1–5 days) are stored locally on the same storage as the VM for fast restores, while daily/weekly/monthly/yearly backup points are stored in the vault's geo-redundant storage. The 'Retain daily backup points' setting defines the number of daily recovery points retained in the vault; increasing it to 30 means Azure Backup will keep each daily backup for 30 days before automatically pruning it. This is independent of the backup frequency—changing frequency only affects how often a new point is created, not how long it lives.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
