The answer is Azure SQL Database elastic pools with per-database min/max DTU or vCore settings. This configuration is correct because it enforces resource isolation and predictable performance for each tenant by allowing you to set a guaranteed minimum and a capped maximum for every database within the shared pool, preventing noisy neighbors from starving others while ensuring each tenant receives a baseline of compute or DTU resources. On the DP-300 exam, this scenario tests your understanding of multi-tenant resource governance versus single-database or managed instance options; a common trap is choosing a standalone database or a hyperscale tier, which lack per-database limits. Remember the key distinction: elastic pools provide shared resources with individual guardrails, not isolated servers. A helpful memory tip is to think of “min for baseline, max for ceiling”—the per-database min/max settings act like a safety net and a cap, giving each tenant predictable performance without over-provisioning.
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 multi-tenant SaaS application. Each tenant has its own database, and you need to ensure that resource usage is isolated and predictable. You also need to manage performance at the tenant level. Which Azure SQL Database offering should you choose?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure SQL Database elastic pools with per-database min/max DTU or vCore settings.
Azure SQL Database elastic pools with per-database min/max DTU or vCore settings are the correct choice because they provide resource isolation and predictable performance at the tenant level. Elastic pools allow you to allocate a shared pool of resources across multiple databases while setting per-database minimum and maximum limits, ensuring that no single tenant can consume excessive resources and that each tenant gets a guaranteed baseline. This directly addresses the multi-tenant SaaS requirement for isolated and predictable resource usage.
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.
✓
Azure SQL Database elastic pools with per-database min/max DTU or vCore settings.
Why this is correct
Elastic pools provide resource isolation and predictable performance per database.
Related concept
Read the scenario before looking for a memorised answer.
✗
Azure SQL Database serverless compute tier.
Why it's wrong here
Serverless is for variable workloads, not predictable isolation.
✗
Azure SQL Database single databases with DTU-based tier.
Why it's wrong here
Single databases are costlier than pooling for multi-tenant.
✗
Azure SQL Managed Instance with multiple databases.
Why it's wrong here
Managed Instance is not designed for multi-tenant isolation at scale.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse elastic pools with serverless or single databases, thinking that serverless provides isolation or that single databases are the only way to guarantee performance, but they miss the key requirement for per-tenant resource control and cost efficiency that elastic pools uniquely offer.
Detailed technical explanation
How to think about this question
Elastic pools use a shared resource model where the pool's total DTU or vCore capacity is divided among databases using per-database min and max settings. The min setting guarantees a baseline for each tenant, while the max prevents a single tenant from starving others, leveraging the pool's aggregate resources efficiently. In a real-world SaaS scenario, this allows you to handle variable tenant workloads without over-provisioning, as the pool automatically redistributes unused capacity among databases within their configured limits.

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.
