- A
Business Critical
Business Critical provides dedicated resources and low latency, suitable for mission-critical applications.
- B
General Purpose
Why wrong: General Purpose uses shared resources and is not optimized for low-latency.
- C
Basic
Why wrong: Basic tier is for small workloads with shared resources and limited performance.
- D
Hyperscale
Why wrong: Hyperscale is for very large databases with flexible storage, not necessarily for predictable low-latency.

DP-300 Plan and implement data platform resources Practice Question
This DP-300 practice question tests your understanding of plan and implement data platform resources. 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 deploying Azure SQL Database for a new application that requires predictable performance and minimal latency. You need to choose a service tier that provides dedicated resources and allows scaling independently for compute and storage. Which service tier should you select?
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
✓
Business Critical
The Business Critical service tier is designed for applications requiring predictable performance and minimal latency, as it provides dedicated resources (CPU and memory) and uses local SSD storage for the database. It also supports independent scaling of compute and storage, allowing you to adjust DTUs or vCores without affecting storage capacity, which aligns with the requirement for independent scaling.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'dedicated resources' with 'General Purpose' because it also offers isolated compute, but they overlook that Business Critical uses local SSD for minimal latency, whereas General Purpose relies on remote storage with higher latency.
Detailed technical explanation
How to think about this question
In the Business Critical tier, each replica uses local SSD for data and log files, ensuring low I/O latency (typically under 1 ms) and high throughput. The tier also provides read-scale replicas and zone-redundant availability, which is critical for applications requiring high availability with minimal performance impact. Independent scaling is achieved by adjusting the service objective (e.g., from 8 vCores to 16 vCores) without changing the maximum storage size, which remains fixed at the tier's limit (up to 4 TB).
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.
