Configure and manage automation of tasks →mediumMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is that weekly backups are retained for 4 weeks. This is because the ARM template snippet sets the `weeklyRetention` property to `P4W`, which is the ISO 8601 duration format where "P" denotes the period, the number indicates the quantity, and "W" stands for weeks. In Azure SQL Database backup long-term retention (LTR) policies, all retention values must be expressed in this standardized ISO 8601 duration format, so `P4W` directly translates to a retention period of exactly four weeks for weekly backups. On the DP-300 exam, this concept tests your ability to read and interpret ARM template parameters, a common task when automating backup policies. A frequent trap is confusing `P4W` with 4 days or misreading the "W" as months; remember that the letter after the number always specifies the unit—W for weeks, M for months, Y for years. A helpful memory tip: think of "P" as "Period" and the letter as the "Unit," so `P4W` is simply "Period 4 Weeks."

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

✓

Weekly backups are retained for 4 weeks.

The ARM template snippet defines a backup long-term retention policy for Azure SQL Database. The `weeklyRetention` property is set to `P4W`, which in ISO 8601 duration format means a period of 4 weeks. Therefore, weekly backups are retained for exactly 4 weeks. Option D correctly reflects this configuration.

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.

  • ✗

    Monthly backups are retained for 24 months.

    Why it's wrong here

    MonthlyRetention is P12M, which is 12 months.

  • ✗

    Weekly backups are retained for 8 weeks.

    Why it's wrong here

    WeeklyRetention is P4W, not P8W.

  • ✗

    Yearly backups are retained for 1 year.

    Why it's wrong here

    YearlyRetention is P5Y, which is 5 years.

  • ✓

    Weekly backups are retained for 4 weeks.

    Why this is correct

    The weeklyRetention property is set to P4W, which is 4 weeks.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often misread the ISO 8601 duration values (e.g., confusing P4W with 4 months or assuming P12M means 24 months) or incorrectly associate the retention period with a different backup frequency (e.g., thinking weekly retention applies to monthly backups).

Detailed technical explanation

How to think about this question

Azure SQL Database long-term retention (LTR) policies use ISO 8601 duration format (e.g., P4W for 4 weeks, P12M for 12 months). The `weeklyRetention` defines how long the most recent full weekly backup is kept; after that period, the backup is automatically deleted. In practice, if you set `weeklyRetention` to P4W, you ensure that for any given week, the backup from that week is available for exactly 4 weeks, which is useful for compliance scenarios requiring short-term weekly recovery points.

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 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.
