DP-300 Configure and manage automation of tasks Practice Question
This DP-300 practice question tests your understanding of configure and manage automation of tasks. 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.
You are configuring automated backup retention for Azure SQL Managed Instance. The compliance policy requires that you be able to restore a database to any point within the last 90 days, and that you keep backups for a minimum of 7 years for auditing purposes. Which backup retention policy should you configure?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set PITR retention to 35 days and configure a long-term retention (LTR) policy to keep weekly backups for 7 years.
Azure SQL Managed Instance's point-in-time restore (PITR) retention is capped at 35 days, so to meet the 90-day restore requirement, you must combine a 35-day PITR policy with a long-term retention (LTR) policy that keeps weekly full backups for 7 years. LTR allows you to restore to any point within the LTR window by using full, differential, and log backups, satisfying both the 90-day point-in-time restore and the 7-year auditing compliance.
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.
✓
Set PITR retention to 35 days and configure a long-term retention (LTR) policy to keep weekly backups for 7 years.
Why this is correct
PITR covers 35 days; LTR can retain backups for up to 10 years, satisfying the 7-year requirement.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Set point-in-time restore (PITR) retention to 90 days.
Why it's wrong here
PITR retention for Azure SQL Managed Instance is limited to 35 days at maximum.
✗
Set PITR retention to 90 days and configure geo-replication to achieve the 7-year retention.
Why it's wrong here
PITR cannot exceed 35 days, and geo-replication does not extend retention.
✗
Configure geo-redundant backup storage with a retention of 90 days.
Why it's wrong here
Geo-redundancy affects storage redundancy, not retention period; PITR retention still maxes at 35 days.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume PITR retention can be extended to any value, but Azure SQL Managed Instance enforces a hard 35-day maximum, forcing you to combine PITR with LTR to meet longer retention requirements.
Detailed technical explanation
How to think about this question
Under the hood, Azure SQL Managed Instance uses automated backups that include full, differential, and transaction log backups. PITR retention controls how far back you can restore using these backups, with a hard limit of 35 days. Long-term retention (LTR) stores weekly full backups in a separate Azure Blob Storage container for up to 10 years, enabling compliance with extended retention policies. In practice, to restore to any point within 90 days, you would use PITR for the first 35 days and then rely on LTR weekly backups combined with differential and log backups for the remaining 55 days, though note that LTR does not support point-in-time restore beyond the last full backup; for precise point-in-time restore within the full 90-day window, you must ensure that the LTR policy includes weekly full backups and that you have a strategy to apply log backups manually if needed.

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.
