The answer is the Serverless deployment option for Azure SQL Database. This is correct because Serverless automatically scales compute resources, measured in vCores, based on real-time demand, and it pauses the database during idle periods, resuming instantly on the first connection—charging per second only for the compute consumed. On the Microsoft Azure Data Fundamentals DP-900 exam, this scenario tests your understanding of compute tiers versus service tiers; a common trap is confusing Serverless with the provisioned DTU or vCore models, which require manual scaling and charge for allocated resources even when idle. Remember that Serverless is purpose-built for unpredictable, bursty workloads like flash sales, where auto-scaling eliminates over-provisioning. A helpful memory tip: think “Serverless = Scale on demand, pay per second, pause when idle.”
DP-900 Practice Question: Identify considerations for relational data on Azure
This DP-900 practice question tests your understanding of identify considerations for relational data on azure. 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. A key principle to apply: azure SQL Database Serverless automatically scales compute based on workload demand.. 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.
A company runs an e-commerce application on Azure SQL Database. The application experiences unpredictable traffic spikes during flash sales and promotional events. The company wants to automatically scale compute resources based on actual demand and pay only for the resources consumed. Which Azure SQL Database deployment option best meets these requirements?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Correct. Serverless compute automatically scales and pauses, ideal for intermittent, unpredictable workloads.
B
Provisioned DTU
Why wrong: Incorrect. DTU-based provisioning uses fixed compute sizes and does not automatically scale based on demand.
C
Provisioned vCore
Why wrong: Incorrect. vCore-based provisioning allows manual scaling but does not automatically scale or pause.
D
Hyperscale
Why wrong: Incorrect. Hyperscale is designed for large databases with fast scaling but does not provide automatic pausing and is more expensive for intermittent workloads.

Correct answer & explanation
✓
Serverless
The Serverless deployment option for Azure SQL Database automatically scales compute resources (vCores) based on actual demand, pausing the database during idle periods and resuming on the first connection. This model charges per second for the compute used, making it ideal for unpredictable traffic spikes like flash sales, as it eliminates the need to over-provision and ensures you pay only for consumed resources.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse Hyperscale's storage scalability with compute auto-scaling, or assume Provisioned tiers can automatically scale without manual intervention, when in fact only Serverless provides automatic compute scaling and per-second billing for intermittent workloads.
Detailed technical explanation
How to think about this question
Under the hood, the Serverless tier uses a compute auto-scaling range (min/max vCores) and an auto-pause delay (configurable from 1 minute to 7 days). During idle periods, the compute is deallocated and only storage and backup costs are incurred; on the next connection, the database resumes within 30–60 seconds. This is ideal for development, test, or intermittent workloads, but note that the first connection after a pause incurs a cold-start latency, which may not suit latency-sensitive production flash sales if the pause delay is set too aggressively.
KKey Concepts to Remember
Azure SQL Database Serverless automatically scales compute based on workload demand.
Serverless databases automatically pause during inactivity and resume instantly.
Billing for Serverless is based on compute consumed per second, plus storage.
It is ideal for intermittent, unpredictable workloads with varying compute requirements.

Key takeaway
Azure SQL Database Serverless automatically scales compute based on workload demand.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
