Overview
Topic 3, ADatum Corporation
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 67
You have an Azure SQL Database server named sqlsrv1 that hosts 10 Azure SQL databases.
The databases perform slower than expected.
You need to identify whether the performance issue relates to the use of tempdb by Azure SQL databases on sqlsrv1.
What should you do?

A. Run dynamic management view-based queries
B. Review information provided by SQL Server Profiler-based traces
C. Run Query Store-based queries
D. Review information provided by Query Performance Insight

Answer: A

Explanation:
The diagnostics log outputs tempDB contention details. You can use the information as the starting point for troubleshooting.
You can use the Intelligent Insights performance diagnostics log of Azure SQL Database to troubleshoot performance issues.

NEW QUESTION 68
You need to recommend an availability strategy for an Azure SQL database. The strategy must meet the following requirements:
* Support failovers that do not require client applications to change their connection strings.
* Replicate the database to a secondary Azure region.
* Support failover to the secondary region.
What should you include in the recommendation?

A. geo-replication
B. Availability Zones
C. failover groups
D. transactional replication

Answer: A

Explanation:
Section: [none]
Explanation:
Active geo-replication is an Azure SQL Database feature that allows you to create readable secondary databases of individual databases on a server in the same or different data center (region).
Incorrect Answers:
C: Availability Zones are unique physical locations within a region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking.

You have an Azure SQL Database instance named DatabaseA on a server named Server1.
You plan to add a new user named App1 to DatabaseA and grant App1 db_datacenter permissions. App1 will
use SQL Server Authentication.
You need to create App1. The solution must ensure that App1 can be given access to other databases by using
the same credentials.
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.
Select and Place:

Answer:

Explanation:

Section: [none]
Explanation:
Step 1: On the master database, run CREATE LOGIN [App1] WITH PASSWORD = 'p@aaW0rd!'
Logins are server wide login and password pairs, where the login has the same password across all databases.
Here is some sample Transact-SQL that creates a login:
CREATE LOGIN readonlylogin WITH password='1231!#ASDF!a';
You must be connected to the master database on SQL Azure with the administrative login (which you get from
the SQL Azure portal) to execute the CREATE LOGIN command.
Step 2: On DatabaseA, run CREATE USER [App1] FROM LOGIN [App1]
Users are created per database and are associated with logins. You must be connected to the database in
where you want to create the user. In most cases, this is not the master database. Here is some sample
Transact-SQL that creates a user:
CREATE USER readonlyuser FROM LOGIN readonlylogin;
Step 3: On DatabaseA run ALTER ROLE db_datareader ADD Member [App1]
Just creating the user does not give them permissions to the database. You have to grant them access. In the
Transact-SQL example below the readonlyuser is given read only permissions to the database via the
db_datareader role.
EXEC sp_addrolemember 'db_datareader', 'readonlyuser';

NEW QUESTION 71
You have an Azure SQL database.
You identify a long running query.
You need to identify which operation in the query is causing the performance issue.
What should you use to display the query execution plan in Microsoft SQL Server Management Studio
(SSMS)?

A. Live Query Statistics
B. Client Statistics
C. an actual execution plan
D. an estimated execution plan

Answer: C

Explanation:
Section: [none]
Explanation:
To include an execution plan for a query during execution
1. On the SQL Server Management Studio toolbar, click Database Engine Query. You can also open an
existing query and display the estimated execution plan by clicking the Open File toolbar button and locating the
existing query.
2. Enter the query for which you would like to display the actual execution plan.
3. On the Query menu, click Include Actual Execution Plan or click the Include Actual Execution Plan toolbar
button.

Note: Actual execution plans are generated after the Transact-SQL queries or batches execute. Because of
this, an actual execution plan contains runtime information, such as actual resource usage metrics and runtime
warnings (if any). The execution plan that is generated displays the actual query execution plan that the SQL
Server Database Engine used to execute the queries.

Overview
Existing Environment
Contoso, Ltd. is a financial data company that has 100 employees. The company delivers financial data to
customers.
Active Directory
Contoso has a hybrid Azure Active Directory (Azure AD) deployment that syncs to on-premises Active
Directory.
Database Environment
Contoso has SQL Server 2017 on Azure virtual machines shown in the following table.

SQL1 and SQL2 are in an Always On availability group and are actively queried. SQL3 runs jobs, provides
historical data, and handles the delivery of data to customers.
The on-premises datacenter contains a PostgreSQL server that has a 50-TB database.
Current Business Model
Contoso uses Microsoft SQL Server Integration Services (SSIS) to create flat files for customers. The
customers receive the files by using FTP.
Requirements
Planned Changes
Contoso plans to move to a model in which they deliver data to customer databases that run as platform as a
service (PaaS) offerings. When a customer establishes a service agreement with Contoso, a separate resource
group that contains an Azure SQL database will be provisioned for the customer. The database will have a
complete copy of the financial data. The data to which each customer will have access will depend on the
service agreement tier. The customers can change tiers by changing their service agreement.
The estimated size of each PaaS database is 1 TB.
Contoso plans to implement the following changes:
* Move the PostgreSQL database to Azure Database for PostgreSQL during the next six months.
* Upgrade SQL1, SQL2, and SQL3 to SQL Server 2019 during the next few months.
* Start onboarding customers to the new PaaS solution within six months.
Business Goals
Contoso identifies the following business requirements:
* Use built-in Azure features whenever possible.
* Minimize development effort whenever possible.
* Minimize the compute costs of the PaaS solutions.
* Provide all the customers with their own copy of the database by using the PaaS solution.
* Provide the customers with different table and row access based on the customer's service agreement.
* In the event of an Azure regional outage, ensure that the customers can access the PaaS solution with
minimal downtime. The solution must provide automatic failover.
* Ensure that users of the PaaS solution can create their own database objects but he prevented from
modifying any of the existing database objects supplied by Contoso.
Technical Requirements
Contoso identifies the following technical requirements:
* Users of the PaaS solution must be able to sign in by using their own corporate Azure AD credentials or
have Azure AD credentials supplied to them by Contoso. The solution must avoid using the internal Azure
AD of Contoso to minimize guest users.
* All customers must have their own resource group, Azure SQL server, and Azure SQL database. The
deployment of resources for each customer must be done in a consistent fashion.
* Users must be able to review the queries issued against the PaaS databases and identify any new objects
created.
* Downtime during the PostgreSQL database migration must be minimized.
Monitoring Requirements
Contoso identifies the following monitoring requirements:
* Notify administrators when a PaaS database has a higher than average CPU usage.
* Use a single dashboard to review security and audit data for all the PaaS databases.
* Use a single dashboard to monitor query performance and bottlenecks across all the PaaS databases.
* Monitor the PaaS databases to identify poorly performing queries and resolve query performance issues
automatically whenever possible.
PaaS Prototype
During prototyping of the PaaS solution in Azure, you record the compute utilization of a customer's Azure SQL
database as shown in the following exhibit.

Role Assignments
For each customer's Azure SQL Database server, you plan to assign the roles shown in the following exhibit.

NEW QUESTION 73
You have an Always On availability group deployed to Azure virtual machines. The availability group contains a database named DB1 and has two nodes named SQL1 and SQL2. SQL1 is the primary replica.
You need to initiate a full backup of DB1 on SQL2.
Which statement should you run?
BACKUP DATABASE DB1 TO URL='https://mystorageaccount.blob.core.windows.net/

A. mycontainer/DB1.bak' with (Differential, STATS=5, COMPRESSION);
BACKUP DATABASE DB1 TO URL='https://mystorageaccount.blob.core.windows.net/
B. mycontainer/DB1.bak' with (File_Snapshot, STATS=5, COMPRESSION);
BACKUP DATABASE DB1 TO URL='https://mystorageaccount.blob.core.windows.net/
C. mycontainer/DB1.bak' with (NoInit, STATS=5, COMPRESSION);
D. mycontainer/DB1.bak' with (COPY_ONLY, STATS=5, COMPRESSION);
BACKUP DATABASE DB1 TO URL='https://mystorageaccount.blob.core.windows.net/

Answer: D

Explanation:
BACKUP DATABASE supports only copy-only full backups of databases, files, or filegroups when it's executed on secondary replicas. Copy-only backups don't impact the log chain or clear the differential bitmap.
Incorrect Answers:
A: Differential backups are not supported on secondary replicas. The software displays this error because the secondary replicas support copy-only database backups.

You create a full database backup of DB1.
You need to add DB1 to the availability group.
Which restore option should you use on the secondary replica?

A. Restore with Recovery
B. Restore with Norecovery
C. Restore with Standby

Answer: B

Explanation:
Section: [none]
Explanation:
Prepare a secondary database for an Always On availability group requires two steps:
1. Restore a recent database backup of the primary database and subsequent log backups onto each server
instance that hosts the secondary replica, using RESTORE WITH NORECOVERY
2. Join the restored database to the availability group.
