Question 392 of 953
Plan and configure a high availability and disaster recovery environment →mediumMultiple ChoiceObjective-mapped

Quick Answer

The correct action is to change the retentionDays property to 30. This is because the point-in-time restore (PITR) retention period for an Azure SQL Database is directly controlled by the retentionDays parameter in an ARM template, and the exhibit shows it set to 14, which fails the compliance requirement of 30 days. The diffBackupIntervalInHours property only governs the frequency of differential backups, not how far back you can restore, so it is irrelevant here. On the Microsoft Azure Database Administrator Associate DP-300 exam, this scenario tests your understanding of backup policy configuration via ARM templates, a common task for automating database deployments. A frequent trap is confusing PITR retention with long-term retention (LTR) or differential backup intervals; remember that retentionDays is the sole property for PITR duration. Memory tip: "PITR Days = retentionDays" — just change the number to meet your compliance window.

DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment

This DP-300 practice question tests your understanding of plan and configure a high availability and disaster recovery environment. 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.

Exhibit

{
  "type": "Microsoft.Sql/servers/databases/backupShortTermRetentionPolicies",
  "apiVersion": "2023-08-01-preview",
  "properties": {
    "retentionDays": 14,
    "diffBackupIntervalInHours": 12
  }
}

Refer to the exhibit. You are reviewing an ARM template for an Azure SQL Database backup policy. The database is used for a reporting workload that is updated daily. The compliance team requires that point-in-time restore (PITR) be available for the past 30 days. What action should you take?

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

✓

Change the retentionDays property to 30.

Option B is correct because the retentionDays property is set to 14, which is less than the required 30 days. The diffBackupIntervalInHours is not relevant for PITR retention. Option A is wrong because PITR retention is not set by the diff backup interval. Option C is wrong because PITR retention is not set by long-term retention. Option D is wrong because 14 days does not meet the requirement.

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 retentionDays property to 30.

    Why this is correct

    retentionDays controls PITR retention; setting to 30 meets the requirement.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Change the diffBackupIntervalInHours to 24.

    Why it's wrong here

    The diff backup interval affects backup frequency, not retention duration.

  • ✗

    No action is needed; the current policy meets the requirement.

    Why it's wrong here

    14 days retention does not satisfy the 30-day PITR requirement.

  • ✗

    Add a long-term retention policy with a weekly retention of 30 days.

    Why it's wrong here

    Long-term retention is for archival, not PITR; PITR requires short-term retention.

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.
