Demo Questions

Question 1
You need to recommend a solution that addresses the index fragmentation and index width issue. 
What should you include in the recommendation? (Each correct answer presents part of the solution. Choose all that apply.)
  1. Change the data type of the lastModified column to smalldatetime.
  2. Remove the lastModified column from the clustered index.
  3. Change the data type of the modifiedBy column to tinyint.
  4. Change the data type of the id column to bigint.
  5. Remove the modifiedBy column from the clustered index.
  6. Remove the id column from the clustered index.
Correct answer: BE
Explanation:
Scenario: Index Fragmentation IssuesCustomers discover that clustered indexes often are fragmented. To resolve this issue, the customers defragment the indexes more frequently. All of the tables affected by fragmentation have the following columns that are used as the clustered index key:

Question 2
You need to recommend a solution that reduces the time it takes to import the supplier data. 
What should you include in the recommendation? 
  1. Enable instant file initialization.
  2. Reorganize the indexes.
  3. Disable Resource Governor.
  4. Enable Auto Update Statistics.
Correct answer: C
Explanation:
* The ERP application relies on an import process to load supplier data. The import process updates thousands of rows simultaneously, requires exclusive access to the database, and runs daily. Resource Governor

Question 3
You need to recommend a solution that meets the data recovery requirement. 
What should you include in the recommendation?
  1. A differential backup
  2. A transaction log backup
  3. Snapshot isolation
  4. A database snapshot
Correct answer: D

Question 4
You need to recommend a solution that addresses the file storage requirements. 
What should you include in the recommendation?
  1. FileStream
  2. FileTable
  3. The varbinary data type
  4. The image data type
Correct answer: B
Explanation:
* Scenario: File Storage RequirementsThe ERP database stores scanned documents that are larger than 2 MB. These files must only be accessed through the ERP application. File access must have the best possible read and write performance. * FileTables remove a significant barrier to the use of SQL Server for the storage and management of unstructured data that is currently residing as files on file servers. Enterprises can move this data from file servers into FileTables to take advantage of integrated administration and services provided by SQL Server. At the same time, they can maintain Windows application compatibility for their existing Windows applications that see this data as files in the file system. Reference: FileTables (SQL Server)

Question 5
You need to recommend a solution that addresses the installation issues. 
What should you include in the recommendation?
  1. Windows logins
  2. Server roles
  3. Contained users
  4. Database roles
Correct answer: C
Explanation:
* Scenario: Installation IssuesThe current version of the ERP application requires that several SQL Server logins be set up to function correctly. Most customers set up the ERP application in multiple locations and must create logins multiple times. * Creating contained users enables the user to connect directly to the contained database. This is a very significant feature in high availability and disaster recovery scenarios such as in an AlwaysOn solution. If the users are contained users, in case of failover, people would be able to connect to the secondary without creating logins on the instance hosting the secondary. This provides an immediate benefit. Contained Databases

Question 6
You need to recommend a solution that addresses the security requirement. 
What should you recommend?
  1. Revoke user permissions on the tables. Create stored procedures that manipulate data. Grant the users the EXECUTE permission on the stored procedures.
  2. Grant the users the SELECT permission on the tables. Create views that retrieve data from the tables. Grant the users the SELECT permission on the views.
  3. Deny the users SELECT permission on the tables. Create views that retrieve data from the tables. Grant the users the SELECT permission on the views.
  4. Deny the users the SELECT permission on the tables. Create stored procedures that manipulate data. Grant the users the EXECUTE permission on the stored procedures.
Correct answer: C
Explanation:
* Security Requirements You must provide users with the ability to execute functions within the ERP application, without having direct access to the underlying tables.
* Security Requirements 
You must provide users with the ability to execute functions within the ERP application, without having direct access to the underlying tables.
Question 7
You need to recommend changes to the ERP application to resolve the search issue. The solution must minimize the impact on other queries generated from the ERP application. 
What should you recommend changing?
  1. The collation of the Products table
  2. The index on the ProductName column
  3. The collation of the ProductName column
  4. The data type of the ProductName column
Correct answer: C

Question 8
You need to recommend a solution that addresses the concurrency requirement. 
What should you recommend?
  1. Break each stored procedure into two separate procedures, one that changes Sales.Table1 and one that changes Sales.Table2.
  2. Make calls to Sales.Proc1 and Sales.Proc2 synchronously.
  3. Call the stored procedures in a Distributed Transaction Coordinator (DTC) transaction.
  4. Modify the stored procedures to update tables in the same order for all of the stored procedures. 
Correct answer: D
Explanation:
* Concurrency Requirements You must reduce the likelihood of deadlocks occurring when Sales.Proc1 and Sales.Proc2 execute.
* Concurrency Requirements 
You must reduce the likelihood of deadlocks occurring when Sales.Proc1 and Sales.Proc2 execute.
Question 9
You need to recommend a solution that addresses the backup issue. The solution must minimize the amount of development effort. 
What should you include in the recommendation?
  1. Indexed views
  2. Filegroups
  3. Table partitioning
  4. Indexes
Correct answer: B
Explanation:
* Backup Issues Customers who have large amounts of historical purchase order data report that backup time is unacceptable. * For very large databases (and by that, I mean, at least 500gb, but more like 5-10tb or more), it can become too expensive to regularly run a straight full backup. So, where needed, you can choose to backup smaller pieces of the database by choosing to back up one of the files or file groups that make up a database. Reference: Using Filegroups and Files to Store Data

Question 10
What should you recommend for the updates to Sales.TransactionHistory?
  1. a REPEATABLE READ isolation level
  2. implicit transactions
  3. query hints
  4. a SNAPSHOT isolation level
