NEW QUESTION # 264
You have an Azure subscription.
You need to deploy a new Azure SQL database by using Azure Command-Line Interface (CLI).
Which three parameters are required?
Answer: D
Explanation:
Basic Concept: This question tests monitor, configure, and optimize database 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 C is Correct: Option C is correct because it is the feature whose normal purpose matches the stated requirement. Option C is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. The scenario wording points to that specific behavior: You need to deploy a new Azure SQL database by using Azure Command-Line Interface (CLI).
Why A is Wrong: Option A is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. It would produce a different operational signal than the one needed to investigate, alert, or tune the workload in this question.
Why B is Wrong: Option B is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. It does not expose the required metric, query history, wait/blocking signal, or tuning mechanism; using it would not give the administrator the evidence requested.
Why D is Wrong: Option D is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. It would produce a different operational signal than the one needed to investigate, alert, or tune the workload in this question.

Overview
ADatum Corporation is a retailer that sells products through two sales channels: retail stores and a website.
Existing Environment
ADatum has one database server that has Microsoft SQL Server 2016 installed. The server hosts three mission-critical databases named SALESDB, DOCDB, and REPORTINGDB.
SALESDB collects data from the stores and the website.
DOCDB stores documents that connect to the sales data in SALESDB. The documents are stored in two different JSON formats based on the sales channel.
REPORTINGDB stores reporting data and contains several columnstore indexes. A daily process creates reporting data in REPORTINGDB from the data in SALESDB. The process is implemented as a SQL Server Integration Services (SSIS) package that runs a stored procedure from SALESDB.
Requirements
Planned Changes
ADatum plans to move the current data infrastructure to Azure. The new infrastructure has the following requirements:
Migrate SALESDB and REPORTINGDB to an Azure SQL database.
Migrate DOCDB to Azure Cosmos DB.
The sales data, including the documents in JSON format, must be gathered as it arrives and analyzed online by using Azure Stream Analytics. The analytics process will perform aggregations that must be done continuously, without gaps, and without overlapping.
As they arrive, all the sales documents in JSON format must be transformed into one consistent format.
Azure Data Factory will replace the SSIS process of copying the data from SALESDB to REPORTINGDB.
Technical Requirements
The new Azure data infrastructure must meet the following technical requirements:
Data in SALESDB must encrypted by using Transparent Data Encryption (TDE). The encryption must use your own key.
SALESDB must be restorable to any given minute within the past three weeks.
Real-time processing must be monitored to ensure that workloads are sized properly based on actual usage patterns.
Missing indexes must be created automatically for REPORTINGDB.
Disk IO, CPU, and memory usage must be monitored for SALESDB.
NEW QUESTION # 266
You have an Azure virtual machine based on a custom image named VM1.
VM1 hosts an instance of Microsoft SQL Server 2019 Standard.
You need to automate the maintenance of VM1 to meet the following requirements:
Automate the patching of SQL Server and Windows Server.
Automate full database backups and transaction log backups of the databases on VM1.
Minimize administrative effort.
What should you do first?
Answer: A
Explanation:
Automated Patching depends on the SQL Server infrastructure as a service (IaaS) Agent Extension. The SQL Server IaaS Agent Extension (SqlIaasExtension) runs on Azure virtual machines to automate administration tasks. The SQL Server IaaS extension is installed when you register your SQL Server VM with the SQL Server VM resource provider.

NEW QUESTION # 267
You need to configure user authentication for the SERVER1 databases. The solution must meet the security and compliance requirements.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Answer:
Explanation:
1 - Create an Azure AD administrator for the locial server
2 - Connect to the databases by using an Azure AD account
Reference:
https://docs.microsoft.com/en-us/azure/azure-sql/database/authentication-aad-overview
NEW QUESTION # 268
Hotspot Question
You have an Azure SQL database named DB1.
You need to create a second instance of DB1 in a different Azure region. The solution must meet the following requirements:
- Ensure that the instance is readable and available to handle incoming queries in the event of a local Azure region failure.
- Minimize administrative effort.
- Minimize costs.
What should you do? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: Geo-replication
To create a readable secondary instance of an Azure SQL Database in a different region while ensuring high availability, low administration, and low costs, you should use Active Geo- Replication.
Active Geo-Replication is the optimal built-in feature for this scenario. It creates a readable, secondary database in a different geographic region. It handles asynchronous replication of data automatically.
Box 2: An active secondary replica
You should create an active secondary replica using Azure SQL Database geo-replication to meet the requirements. This solution directly satisfies your needs for readability, high availability during a regional failure, low administration, and cost-efficiency.
