Questions 21

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You have an Azure Synapse Analytics dedicated SQL pool that contains a table named Table1.

You have files that are ingested and loaded into an Azure Data Lake Storage Gen2 container named container1.

You plan to insert data from the files into Table1 and transform the data. Each row of data in the files will produce one row in the serving layer of Table1.

You need to ensure that when the source data files are loaded to container1, the DateTime is stored as an additional column in Table1.

Solution: You use a dedicated SQL pool to create an external table that has an additional DateTime column.

Does this meet the goal?

Options:

Yes

Questions 23

Based on the PaaS prototype, which Azure SQL Database compute tier should you use?

Options:

Business Critical 4-vCore

Hyperscale

General Purpose v-vCore

Serverless

Answer:

Explanation:

There are CPU and Data I/O spikes for the PaaS prototype. Business Critical 4-vCore is needed.

[Reference:, https://docs.microsoft.com/en-us/azure/azure-sql/database/reserved-capacity-overview, , , , , , Basic Concept: This question tests Azure SQL sizing and purchasing choices, where compute model, scaling behavior, licensing benefits, and cost pattern must be evaluated together., Why D is Correct: The serverless tier automatically scales compute and can pause during inactive periods, making it suitable for intermittent workloads with bursts and idle windows. The scenario asks for: Based on the PaaS prototype, which Azure SQL Database compute tier should you use? That makes Serverless the option that satisfies the required Azure SQL layer and operational outcome., Why A is Wrong: Business Critical provides low-latency local SSD storage and high availability for demanding workloads, but it is usually more expensive than necessary for bursty idle workloads. That design keeps capacity available for a different kind of workload and does not match the cost behavior expected from an idle-and-burst database pattern., Why B is Wrong: Hyperscale is designed for very large databases and fast scale-out storage architecture, not merely for intermittent CPU bursts. That design keeps capacity available for a different kind of workload and does not match the cost behavior expected from an idle-and-burst database pattern., Why C is Wrong: The vCore purchasing model separates compute and storage sizing and supports Azure Hybrid Benefit for eligible SQL Server licenses. It applies to a different Azure data-platform design than the one the question is testing., Verification Note: The original listed answer was A; the corrected answer is D because The prototype shows intermittent spikes with idle periods; the serverless compute tier is designed for intermittent usage and automatic pause/resume cost savings., ]
