Exam DP-300 topic 1 question 53 discussion

We have five bds, SQL Database in serverless compute tier is for single databases.... so we would need no a single serverless SQL Databases... but five. We need to automatically scale compute based on workload, and be billed by the second...For five databses we would create an elastic pool ( with fixed min and max resources for automatic compute scaling of the bds), using vCore model, with provisioned compute tier so we are charged by the second(DTU model charges by hour). vCore model has General Purpose, Business Critical, and Hyperscale.... we would use GEneral purpose. Serverless compute tier es for single databases... so we would need five servers SQL Databases.... not "a single Azure SQL databases in the serverless compute tier".

In the answer area, you should choose: Azure service: A single Azure SQL database in the serverless compute tier Service tier: General Purpose Here’s the explanation: A single Azure SQL database in the serverless compute tier: This service automatically scales compute based on the workload demand, which is one of your requirements. Additionally, the serverless tier offers per-second billing, allowing you to pay only for the compute you use. General Purpose service tier: This tier is typically available with the serverless compute model and offers a balanced and scalable compute and storage options suitable for most business workloads.

Serverless is a compute tier for single databases in Azure SQL Database that automatically scales compute based on workload demand and bills for the amount of compute used per second. Serverless compute tier - Azure SQL Database | Microsoft Learn

Azure Service: Serveless computer tier Service Tier: General Purpose the key word is "per second billing" , serveless is the option to use, and General Purpose Service Tier works with it

The question talk about five database, so the answer "A single serverless SQL Database" must be to exclude. The only possible is the elastic pool ( with fixed min and max resources for automatic compute scaling). The tier must be a vCore one, because DTU is charged by hour, so the second answer is General Puropse
