QUESTION 4
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 sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
A company has a server that runs Microsoft SQL Server 2016 Web edition. The server has a default instance that hosts a database named DB1.

QUESTION 6
You have a database that stores information for a shipping company. You create a table named Customers by running the following Transact-SQL statement. 70-764 dumps (Line numbers are included for reference only.)
You need to ensure that salespeople can view data only for the customers that are assigned to them.
Which Transact-SQL segment should you insert at line 07?
A. RETURNS varchar(20)WITH Schemabinding
B. RETURNS dbo.CustomersORDER BY @salesPerson
C. RETURNS tableORDER BY @salesPerson
D. RETURNS tableWITH Schemabinding
Correct Answer: D
Explanation:
The return value can either be a scalar (single) value or a table. SELECT 1 just selects a 1 for every row, of course. What it’s used for in this case is testing whether any rows exist that match the criteria: if a row exists that matches the WHERE clause, then it returns 1, otherwise it returns nothing. Specify the WITH SCHEMABINDING clause when you are creating the function. This ensures that the objects referenced in the function definition cannot be modified unless the function is also modified.
QUESTION 7
You are the administrator for a SQL Server 2016 instance that stores the data for an online transaction processing sales system.
The company takes full backups every week; differential backups on the days with no full backups; and hourly transaction backups. These backups are stored on a backup server in the company’s data center.
Every week, the company places the full backup on a tape and sends it to a third-party backup storage system.
The company is worried that a disaster might occur that could destroy their computer center and cause them to lose orders.
You need to determine the best method for providing the smallest amount of data loss and downtime without leasing or purchasing additional physical locations.
What should you do? More than one answer choice may achieve the goal. Select the BEST answer.
A. Set up SQL Server Always On with a SQL Azure database as a replica.
B. Set up SQL Server Always On by using a SQL Server on a Windows Azure Virtual Machine.
C. Put the differential backup on tape and send it to the third-party backup storage system.
D. Use the Microsoft SQL Server Backup to Microsoft Windows Azure Tool to direct all backups to a different geographical location.
Correct Answer: D
Explanation:
SQL Server 2012 was the first version to provide the ability to back up databases to the Cloud, and SQL Server 2016 improves on the process.
Microsoft SQL Server Backup to Windows Azure Tool enables backup to Windows Azure Blob Storage and encrypts and compresses SQL Server backups stored locally or in the cloud.

QUESTION 8
Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series.
Information and details provided in a question apply only to that question.
You are the database administrator for a company that hosts Microsoft SQL Server. You manage both on-premises and Microsoft Azure SQL Database environments.
You have a user database named HRDB that contains sensitive human resources data.
The HRDB backup files must be encrypted.
You need to grant the correct permission to the service account that backs up the HRDB database.
Which permission should you grant?
A. DDLAdmin
B. db_datawriter
C. dbcreator
D. dbo
E. View Database State
F. View Server State
G. View Definition
H. sysadmin
Correct Answer: G
Explanation:
Restoring the encrypted backup: SQL Server restore does not require any encryption parameters to be specified during restores. It does require that the certificate or the asymmetric key used to encrypt the backup file be available on the instance that you are restoring to. The user account performing the restore must have VIEW DEFINITION permissions on the certificate or key.
QUESTION 9
Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
You have five servers that run Microsoft Windows 2012 R2. Each server hosts a Microsoft SQL Server instance. The topology for the environment is shown in the following diagram.
You have an Always On Availability group named AG1. The details for AG1 are shown in the following table.
Instance1 experiences heavy read-write traffic. The instance hosts a database named OperationsMain that is four terabytes (TB) in size. The database has multiple data files and filegroups. One of the filegroups is read_only and is half of the total database size.
Instance4 and Instance5 are not part of AG1. Instance4 is engaged in heavy read-write I/O.
Instance5 hosts a database named StagedExternal. A nightly BULK INSERT process loads data into an empty table that has a rowstore clustered index and two nonclustered rowstore indexes.
You must minimize the growth of the StagedExternal database log file during the BULK INSERT operations and perform point-in-time recovery after the BULK INSERT transaction. Changes made must not interrupt the log backup chain.
You plan to add a new instance named Instance6 to a datacenter that is geographically distant from Site1 and Site2. You must minimize latency between the nodes in AG1.
All databases use the full recovery model. All backups are written to the network location \\SQLBackup\. A separate process copies backups to an offsite location. You should minimize both the time required to restore the databases and the space required to store backups. The recovery point objective (RPO) for each instance is shown in the following table.
Full backups of OperationsMain take longer than six hours to complete. All SQL Server backups use the keyword COMPRESSION.
You plan to deploy the following solutions to the environment. The solutions will access a database named DB1 that is part of AG1.
The wait statistics monitoring requirements for the instances are described in the following table.
You need to create a backup plan for Instance4.
Which backup plan should you create?
A. Weekly full backups, nightly differential. No transaction log backups are necessary.
B. Weekly full backups, nightly differential backups, transaction log backups every 5 minutes.
C. Weekly full backups, nightly differential backups, transaction log backups every 12 hours.
D. Weekly full backups, nightly differential backups, nightly transaction log backups.
Correct Answer: B
Explanation:
From scenario: Instance4 and Instance5 are not part of AG1. Instance4 is engaged in heavy read-write I/O. The recovery point objective of Instancse4 is 60 minutes. RecoveryPoint Objectives are commonly described as the amount of data that was lost during the outage and recovery period.
QUESTION 10
You have a server that has SQL Server 2016 installed. The server contains 100 user databases.
You need to recommend a backup solution for the user databases.
The solution must meet the following requirements:
Perform a transaction log backup every hour.
Perform a full backup of each database every week. Perform a differential backup of each database every day. Ensure that new user databases are added automatically to the backup solution.
What should you recommend?
More than one answer choice may achieve the goal. Select the BEST answer.
A. Policy-Based Management
B. A Data Definition Language (DDL) trigger
C. SQL Server Agent jobs
D. A maintenance plan
Correct Answer: D
Explanation:
Maintenance plans create a workflow of the tasks required to make sure that your database is optimized, regularly backed up, and free of inconsistencies.
Maintenance plans can be created to perform the following task (among others):
Back up the database and transaction log files. Database and log backups can be retained for a specified period. This lets you create a history of backups to be used if you have to restore the database to a time earlier than the last database backup. You can also perform differential backups.
