The answer is that the database must be on Gen5 hardware and must be a single database, not part of an elastic pool. The serverless compute tier is designed to auto-scale compute resources and automatically pause during idle periods, a behavior that conflicts with the shared, fixed-resource model of elastic pools where multiple databases compete for the same allocation. On the DP-300 exam, this requirement tests your understanding of how serverless differs from provisioned tiers, often appearing as a trap where candidates mistakenly think any database can be serverless. A common memory tip is to remember “single and Gen5” — if the database is in a pool or on older hardware, serverless is not an option.
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.
Which TWO conditions must be met to use Azure SQL Database serverless compute tier?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The database must be a single database, not part of an elastic pool
Option C is correct because Azure SQL Database serverless compute tier is designed only for single databases, not for databases in elastic pools. The serverless tier auto-scales compute resources based on workload demand and pauses during idle periods, which is incompatible with the shared resource model of elastic pools where multiple databases share a fixed set of resources.
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.
✗
The database must use the DTU purchasing model
Why it's wrong here
Serverless uses the vCore model.
✗
The database must be in the Hyperscale service tier
Why it's wrong here
Hyperscale does not support serverless.
✓
The database must be a single database, not part of an elastic pool
Why this is correct
Serverless is only for single databases.

✗
The database must be in the General Purpose service tier
Why it's wrong here
Serverless supports General Purpose and Business Critical.
✓
The database must be on a Gen5 hardware
Why this is correct
Serverless requires Gen5.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume serverless is tied to a specific service tier (like Hyperscale) or purchasing model (like DTU), when in fact it requires the vCore model, General Purpose tier, single database, and Gen5 hardware—and the question asks for two conditions, so you must pick both C and E, not just one.
Detailed technical explanation
How to think about this question
The serverless compute tier uses a compute autoscaling range (min and max vCores) and an auto-pause delay setting (in minutes) to manage costs. Under the hood, Azure SQL Database uses a compute replica that can scale up or down within seconds, and when idle beyond the pause delay, the compute resources are deallocated and billing stops, while storage remains active. A real-world scenario is a development or reporting database with sporadic usage, where serverless can significantly reduce costs compared to provisioned compute, but it cannot be used in elastic pools because pools require always-on compute to handle burst activity from any member database.

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.
