Describe core data concepts →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is 5 GB, as this is the fixed maximum size for an Azure SQL Database deployed in the Basic tier. This limit is a hard cap defined by the service tier’s resource governance, which prioritizes low cost and predictable performance for small-scale workloads, making it unsuitable for databases requiring more than 5 GB of storage. On the Microsoft Azure Data Fundamentals DP-900 exam, this concept tests your understanding of how service tiers directly constrain database properties like maximum size, often appearing in ARM template or provisioning scenarios. A common trap is confusing the Basic tier’s 5 GB limit with the Standard tier’s much larger sizes (up to 1 TB), so remember that Basic is intentionally limited for lightweight use cases. Memory tip: think “Basic = 5 GB” as in “B for Basic, B for 5 (as in the letter B’s position in the alphabet is 2, but 5 is the next small number).”

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

✓

5 GB

The ARM template for an Azure SQL Database deployment specifies the database size based on the selected service tier and performance level. For the Basic tier, the maximum database size is 5 GB, which is the correct answer. This is a fixed limit for Basic tier databases, while higher tiers like Standard or Premium support larger sizes.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    5 GB

    Why this is correct

    5,368,709,120 bytes = 5 GB.

  • ✗

    50 GB

    Why it's wrong here

    The value is 5 GB.

  • ✗

    5 MB

    Why it's wrong here

    The value is 5 GB, not MB.

  • ✗

    500 GB

    Why it's wrong here

    The value is 5 GB.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often assume all Azure SQL Database tiers support large sizes (like 500 GB) or confuse the Basic tier's 5 GB limit with the much smaller 5 MB, forgetting that Basic is designed for low-cost, small-scale workloads.

Detailed technical explanation

How to think about this question

Azure SQL Database uses a resource governance model where the maximum database size is enforced by the service tier (DTU or vCore model). For the Basic tier (DTU model), the max size is 5 GB, with a log rate limit of 0.5 MB/sec. In contrast, the Standard tier (S0-S12) allows up to 250 GB, and Premium up to 4 TB. The ARM template's 'maxSizeBytes' property must match the tier's allowed range; specifying a value outside this range will cause a deployment error.

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 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.
