Your company plans to use Microsoft Azure Resource Manager templates for all future deployments of SQL Server on Azure virtual machines.
You need to create the templates.
Solution: You use Visual Studio to create a XML template that defines the deployment and configuration settings for the SQL Server environment.
Does the solution meet the goal?

  • A. Yes
  • B. No


Answer : B

Explanation:
Azure Resource Manager template consists of JSON, and expressions that you can use to construct values for your deployment.
A good JSON editor, not a Resource Group template, can simplify the task of creating templates.
Note: In its simplest structure, an Azure Resource Manager template contains the following elements:
{
"$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "",
"parameters": { },
"variables": { },
"resources": [ ],
"outputs": { }
}

You plan to deploy 20 Microsoft Azure SQL Database instances to an elastic pool in Azure to support a batch processing application.
Two of the databases in the pool reach their peak workload threshold at the same time every day. This leads to inconsistent performance for batch completion.
You need to ensure that all batches perform consistently.
What should you do?

  • A. Limit the maximum number of elastic Database Transaction Units (eDTUs) per database
  • B. Increase the storage limit in the pool
  • C. Create an In-Memory table
  • D. Create an elastic job


Answer : A

Explanation:
In SQL Database, the relative measure of a database's ability to handle resource demands is expressed in Database Transaction Units (DTUs) for single databases and elastic DTUs (eDTUs) for databases in an elastic pool.
A pool is given a set number of eDTUs, for a set price. Within the pool, individual databases are given the flexibility to auto-scale within set parameters. Under heavy load, a database can consume more eDTUs to meet demand.
Additional eDTUs can be added to an existing pool with no database downtime.

Answer :

You are planning a Microsoft SQL Server deployment. You do not have a Storage Area Network (SAN) or Network Attached Storage (NAS) infrastructure.
You have a physical host that has 128 gigabytes (GB) RAM, two â€"core processors, and two 1 GB network interface cards (NICs). The host supports RAID through a write-caching RAID controller. The RAID controller is not specifically designed for DBMS systems. The host can support up to eight physically attached disks.
The system does not include a battery backup power supply.
You must implement SQL Server best practices when installing and configuring the server to host SQL Server.
You need to configure the system to support a SQL Server installation by using best practices.
What should you do?

  • A. Increase the RAM in the server.
  • B. Disable write-caching on the RAID controller.
  • C. Configure NIC Teaming.
  • D. Add two more processors.


Answer : B

You are the database administrator for your company. Your company has one main office and two branch offices. You plan to create three databases named DB1,
DB2, and DB3 that will be hosted on one Azure SQL Database server. You have the following requirements:
-> The main office must be able to connect to all three databases.
-> The branch offices must be able to connect to DB2 and DB3.
-> The branch offices must not be able to access DB1.
You need to configure transparent data encryption (TDE) for DB1.
Which two actions should you perform? Each correct answer presents part of the solution.

  • A. Run CREATE CERTIFICATE certl WITH Subject = TDE Cert1 on DB1.
  • B. Connect to DB1.
  • C. Run ALTER DATABASE DB1 SET ENCRYPTION ON;.
  • D. Connect to the master database.
  • E. Run CREATE MASTER KEY on the master database.


Answer : BC

Explanation:
You should connect to DB1. To encrypt DB1, you connect directly to DB1. When you connect to DB1.
You use your dbmanager or administrative credentials.
You should run ALTER DATABASE DB1 SET ENCRYPTION ON.
You use the ALTER DATABASE DB1 SET ENCRYPTION ON statement to encrypt the database. This is the statement that turns on TDE for Azure SQL
Database.
Incorrect Answers:
A: You should not run CREATE CERTIFICATE certl WITH Subject = TDE Cert' on DB1. You do not need to create a certificate to encrypt an Azure SQL database. This would be a part of the solution when you encrypt an on-premises database. You should not connect to the master database. To encrypt DB1, you need to connect directly to DB1. not to the master database.
E: You should not run CREATE MASTER KEY on the master database.
You would execute CREATE MASTER KEY when you have to encrypt an on-premises database.

You have a server named Serverl that is hosted in an Azure virtual machine. Server1 contains the following:
-> One instance of SQL Server 2016 Enterprise
-> 10 databases
-> 500 stored procedures
You have a database named Databasel that is hosted on Server1.
Database1 contains 100 queries that are executed dynamically from web applications.
You plan to remove data from the procedure cache on Database1.
You have the following requirements:
Changes to Database1 must not affect other databases that are hosted on Server1


-> Changes to Database1 must not affect the performance of queries that are stored in other databases.
-> The solution must minimize administrative effort.
You need to remove the data from the procedure cache as quickly as possible.
What should you do?

  • A. Run DBCC FREEPROCCACHE.
  • B. Run ALTER DATABASE SCOPED CONFIGURATION CLEAR PROCEDURE CACHE in the context of Database 1.
  • C. Run DBCC DROPCLEANBUFFERS.
  • D. Write a script that iterates through each stored procedure definition and add WITH RECOMPILE to the definition.


Answer : B

Explanation:
You should run ALTER DATABASE SCOPED CONFIGURATION CLEAR PROCEDURE CACHE in the context of Database! This statement lets you change the settings of a database without affecting other databases that are installed on the instance of SQL Server 2016.
Incorrect Answers:
A: You should not run DBCC FREEPROCCACHE. DBCC FREEPROCCACHE would clean the entire plan cache and would affect all databases. It is possible to remove a single plan from the cache by using the plan_handle argument to DBCC FREEPROCCACHE, but you would have to identify all plans that are related to
Databasel, which requires a lot more administrative effort.
C: You should not run DBCC DROPCLEANBUFFERS. DBCC DROPCLEANBUFFERS will remove the clean pages from the buffer cache. Columnstore pages are removed from the columnstore cache.
D: You should not write a script that will iterate through each stored procedure definition and add WITH RECOMPILE to the definition. Each time the procedure is called, it will be recompiled, and this might degrade the server's performance.
This approach would require additional administrative effort to produce the script. In addition, some calls are made from the web application and the script would not have any control over these calls. In earlier versions of SQL Server, prior to the availability of the ALTER DATABASE statement, this option would have been the way to avoid affecting other databases.
