최신Microsoft Administering a SQL Database Infrastructure - 70-764무료샘플문제

문제1
Your company has offices in Seattle and Montreal.
The network contains two servers named Server1 and Server2 that have SQL Server 2012 installed. The servers are located in separate building within your campus.
The latency of the WAN link between the buildings is less than 10 ms.
You plan to implement an AlwaysOn availability group on both servers.
You need to recommend a failover type for the availability group.
What should you recommend?

문제2
You administer two Microsoft SQL Server 2016 servers named ProdSrv1 and ProdSrv2. ProdSrv1 is configured as a Distributor.
Both servers are configured to use the Windows NT Service virtual accounts for all SQL Services.
You are configuring snapshot replication from ProdSrv1 to ProdSrv2 by using ProdSrv2 as a pull subscriber.
The distribution agent on ProdSrv2 regularly fails, displaying the following error message:
"Cannot access the file. Operating system error code 5 (Access is denied.)." You need to configure the distribution agent by granting only the minimum required access to all accounts.
What should you do?

문제3
You are designing an authentication strategy for a new server that has SQL Server 2014 installed. The strategy must meet the following business requirements:
* The account used to generate reports must be allowed to make a connection during certain hours only.
* Failed authentication requests must be logged.
You need to recommend a technology that meets each business requirement. The solution must minimize the amount of events that are logged.
Which technologies should you recommend? To answer, drag the appropriate solution to the correct business requirement in the answer area.

문제4
You store Microsoft SQL Server backups at an off-site location that has no protection from unauthorized access. Your organization has not implemented hardware security modules (HSM).
You need to implement a solution for encrypting the SQL backups.
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.

문제5

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 administer a SQL Server Instance at Contoso Ltd.
A new employee named Kim Ralls must be able to read data only from the dbo.Order table in the SalesDB database.
You create a SQL login named KimRalls. You then create a SQL user account named KimRalls in SalesDB.
The user account is associated with the SQL login.
You need to grant KimRalls the necessary permission or permissions. Your solution must follow the principle of least privilege.
Solution: You perform the following actions:
* Create a custom database role named OrderReader in SalesDB.
* Grant the View Definition permission on dbo.Order to the OrderReader role.
* Add KimRalls to the OrderReader role.
Does the solution meet the goal?

Overview
General Overview
ADatum Corporation has offices in Miami and Montreal.
The network contains a single Active Directory forest named adatum.com. The offices connect to each other by using a WAN link that has 5-ms latency.
A: Datum standardizes its database platform by using SQL Server
2014 Enterprise edition.
Databases
Each office contains databases named Sales, Inventory, Customers, Products, Personnel, and Dev.
Servers and databases are managed by a team of database administrators. Currently, all of the database administrators have the same level of permissions on all of the servers and all of the databases.
The Customers database contains two tables named Customers and Classifications.
The following graphic shows the relevant portions of the tables:

The following table shows the current data in the Classifications table:

The Inventory database is updated frequently.
The database is often used for reporting.
A full backup of the database currently takes three hours to complete.
Stored Procedures
A stored procedure named USP_1 generates millions of rows of data for multiple reports. USP_1 combines data from five different tables from the Sales and Customers databases in a table named Table1.
After Table1 is created, the reporting process reads data from Table1 sequentially several times. After the process is complete, Table1 is deleted.
A stored procedure named USP_2 is used to generate a product list. The product list contains the names of products grouped by category.
USP_2 takes several minutes to run due to locks on the tables the procedure accesses. The locks are caused by USP_1 and USP_3.
A stored procedure named USP_3 is used to update prices. USP_3 is composed of several UPDATE statements called in sequence from within a transaction.
Currently, if one of the UPDATE statements fails, the stored procedure fails. A stored procedure named USP_4 calls stored procedures in the Sales, Customers, and Inventory databases.
The nested stored procedures read tables from the Sales, Customers, and Inventory databases. USP_4 uses an EXECUTE AS clause.
All nested stored procedures handle errors by using structured exception handling. A stored procedure named USP_5 calls several stored procedures in the same database. Security checks are performed each time USP_5 calls a stored procedure.
You suspect that the security checks are slowing down the performance of USP_5. All stored procedures accessed by user applications call nested stored procedures.
The nested stored procedures are never called directly.
Design Requirements
Data Recovery
You must be able to recover data from the Inventory database if a storage failure occurs. You have a Recovery Time Objective (RTO) of 5 minutes.
You must be able to recover data from the Dev database if data is lost accidentally. You have a Recovery Point Objective (RPO) of one day.
Classification Changes
You plan to change the way customers are classified. The new classifications will have four levels based on the number of orders. Classifications may be removed or added in the future. Management requests that historical data be maintained for the previous classifications. Security A group of junior database administrators must be able to manage security for the Sales database. The junior database administrators will not have any other administrative rights.
A: Datum wants to track which users run each stored procedure.
Storage
ADatum has limited storage. Whenever possible, all storage space should be minimized for all databases and all backups.
Error Handling
There is currently no error handling code in any stored procedure.
You plan to log errors in called stored procedures and nested stored procedures. Nested stored procedures are never called directly.
You need to recommend a solution for the error handling of USP_3. The solution must minimize the amount of custom code required. What should you recommend?

문제7
You create a stored procedure that retrieves all of the rows from a table named Table1.
You need to recommend a solution to ensure that all of the statements in the stored procedure can be executed if another transaction is modifying rows in Table1 simultaneously.
What should you recommend?

문제8
You work as a Database Administrator (DBA) for a company named ABC.com.
The company uses a Microsoft SQL Server 2012 infrastructure.
You have a database named CorpDB.
A full backup of CorpDB is taken every week.
A differential backup of CorpDB is taken every night at midnight.
A transaction log backup of CorpDB is taken at 8am, 12pm, 4pm and 8pm.
You plan to deploy some changes to CorpDB at after the 4pm log backup completes.
You need to ensure that you can undo the changes quickly if the deployment fails.
During the deployment of the changes, no other changes must be made by users to the database. You need a backup and recovery strategy for deploying the changes.
Which two of the following actions would meet the backup and recovery requirements whilst ensuring the regular backup schedule is not disrupted? (Choose two.)
