NEW QUESTION # 268
You have an Azure subscription that contains an Azure SQL database named SQLDb1. SQLDb1 contains a table named Table1.
You plan to deploy an Azure web app named webapp1 that will export rows in Table1 that have changed.
You need to ensure that webapp1 can identity the changes to Table'. The solution must meet the following requirements:
* Minimize compute times.
* Minimize storage.

Answer:
Explanation:
1 - Connect to SQLDb1 and run the following Transact-SQL, statment,,,,,,
2 - Connect to SQLDb1 and run the following Transact-SQL, statment, ALTER TABLE dbo.Table ENABLE CHANGE_TRACKING
3 - From webapp1,connect to SQLDb1,Obtain the,,,,,,,,
NEW QUESTION # 269
You are planning a solution that will use Azure SQL Database. Usage of the solution will peak from October
1 to January 1 each year.
During peak usage, the database will require the following:
24 cores
500 GB of storage
124 GB of memory
More than 50,000 IOPS
During periods of off-peak usage, the service tier of Azure SQL Database will be set to Standard.
Which service tier should you use during peak usage?
Answer: B
Explanation:
Reference:
https://docs.microsoft.com/en-us/azure/azure-sql/database/resource-limits-vcore-single-databases#business- critical---provisioned-compute---gen4 Basic Concept: This question tests plan and implement data platform resources in the DP-300 exam context.
The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
Why A is Correct: Business Critical matches the expected DP-300 administration action. 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. The question is not asking for a general Azure capability; it is asking for the feature that produces this result: You are planning a solution that will use Azure SQL Database.
Why B is Wrong: Premium is an Azure data-platform feature, but it must match the workload model, service tier, migration path, or deployment constraint described in the scenario. It would solve a neighboring problem, but not the deployment, sizing, or migration requirement in this item.
Why C is Wrong: Hyperscale is designed for very large databases and fast scale-out storage architecture, not merely for intermittent CPU bursts. It mismatches the target platform, migration method, compute tier, or deployment model described in the scenario, so it would not satisfy the workload as stated.
NEW QUESTION # 270
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 dat a. 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 an Azure Synapse Analytics serverless SQL pool to create an external table that has an additional DateTime column.
Does this meet the goal?
Answer: B
Explanation:
In dedicated SQL pools you can only use Parquet native external tables. Native external tables are generally available in serverless SQL pools.
Reference:
https://docs.microsoft.com/en-us/azure/synapse-analytics/sql/create-use-external-tables
NEW QUESTION # 271
You have an Azure SQL server named sqlsrv1 that hosts a database named db1.
You have an Azure DevOps pipeline that deploys schema changes to db1 by running an Azure Command- Line Interface (CLI) script from a Microsoft-hosted agent.
You need to ensure that the agent can communicate with sqlsrv1.
How should you complete the script? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
