The answer is that the script sets the short-term backup retention to 7 days, enabling point-in-time restore within that period. This is because the PowerShell cmdlet configures the short-term backup retention policy for the Azure SQL Database, and point-in-time restore (PITR) relies on this retention window to recover the database to any point within the specified range. On the Microsoft Azure Solutions Architect Expert AZ-305 exam, this concept tests your understanding of backup and recovery strategies, specifically how short-term retention directly controls PITR capabilities, while long-term retention (LTR) handles yearly or monthly archival backups. A common trap is confusing the default 7-day retention with the configurable maximum of 35 days for short-term backups, or assuming the script affects LTR policies. Remember the memory tip: “PITR is short-term; LTR is long-term—7 days is the default PITR floor.”
AZ-305 Design business continuity solutions Practice Question
This AZ-305 practice question tests your understanding of design business continuity solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 reviewing a PowerShell script for Azure SQL Database. The exhibit shows the script that sets backup retention. What is the effect of running this script?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It sets the short-term backup retention to 7 days, enabling point-in-time restore within that period.
The script sets the short-term backup retention policy to 7 days for the database 'mydb'. This means point-in-time restore (PITR) backups are retained for 7 days. Option A is incorrect because it says 14 days. Option D is incorrect because it only affects short-term retention.
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.
✓
It sets the short-term backup retention to 7 days, enabling point-in-time restore within that period.
Why this is correct
Short-term retention applies to point-in-time restore backups.
Related concept
Read the scenario before looking for a memorised answer.
✗
It enables geo-redundant backups for the database.
Why it's wrong here
The cmdlet does not affect geo-redundancy.
✗
It sets the long-term retention (LTR) backup policy to 7 days.
Why it's wrong here
The cmdlet is for short-term retention, not long-term.
✗
It increases the backup retention from 7 to 35 days.
Why it's wrong here
The script sets retention to 7 days, not increases it.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
