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 have deployed several GS-series virtual machines (VMs) in Microsoft Azure. You plan to deploy Microsoft SQL Server in a development environment. Each VM has a dedicated disk for backups.
You need to backup a database to the local disk on a VM. The backup must be replicated to another region.
Which storage option should you use?
A. Premium P10 disk storage
B. Premium P20 diskstorage
C. Premium P30 disk storage
D. Standard locally redundant disk storage
E. Standard geo-redundant disk storage
F. Standard zone redundant blob storage
G. Standard locally redundant blob storage
H. Standard geo-redundant blob storage
Correct Answer: E
Note: SQL Database automatically creates a database backups and uses Azure readaccess geo-redundant storage (RA-GRS) to provide geo-redundancy. These backups are created automatically and at no additional charge. You don\’t need to do anything to make them happen. Database backups are an essential part of any business continuity and disaster recovery strategy because they protect your data from accidental corruption or deletion.

You administer a SQL Server 2014 server that contains a database named SalesDb. SalesDb contains a schema named Customers that has a table named Regions. A user named UserA is a member of a role named Sales. UserA is granted
the Select permission on the Regions table. The Sales role is granted the Select permission on the Customers schema.
You need to ensure that the following requirements are met:
Which Transact-SQL statement should you use?
A. REVOKE SELECT ON Schema::Customers FROM UserA
B. DENY SELECT ON Object::Regions FROM UserA
C. EXEC sp_addrolemember \’Sales\’, \’UserA\’
D. DENY SELECT ON Object::Regions FROM Sales
E. REVOKE SELECT ON Object::Regions FROM UserA
F. DENY SELECT ON Schema::Customers FROM Sales
G. DENY SELECT ON Schema::Customers FROM UserA
H. EXEC sp_droprolemember \’Sales\’, \’UserA\’
I. REVOKE SELECT ON Object::Regions FROM Sales
J. REVOKE SELECT ON Schema::Customers FROM Sales
Correct Answer: J
Use REVOKE to remove the grant or deny of a permission. References:https://docs.microsoft.com/en-us/sql/t-sql/statements/permissions-grant-deny- revoke-azure-sql-data-warehouse-parallel-data-warehouse
You administer a Microsoft SQL Server 2014 instance that contains a financial database hosted on a storage area network (SAN).
The financial database has the following characteristics:
The database is continually modified by users during business hours from Monday through Friday between 09:00 hours and 17:00 hours. Five percent of the existing data is modified each day.
The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of data to the database.
These data load operations must occur in the minimum amount of time.
A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours.
You need to ensure that your backup will continue if any invalid checksum is encountered.
Which backup option should you use?
L. Transaction log
Correct Answer: F
The CONTINUE_AFTER_ERROR option, of the Transact-SQL BACKUP command, instructs BACKUP to continue despite encountering errors such as invalid checksums or torn pages. https://docs.microsoft.com/en-us/sql/t-sql/statements/backup-transact-sql
You use a Microsoft SQL Server 2014 database that contains two tables named SalesOrderHeader and SalesOrderDetail. The indexes on the tables are as shown in the exhibit. (Click the Exhibit button.)
You write the following Transact-SQL query:
You discover that the performance of the query is slow. Analysis of the query plan shows table scans where the estimated rows do not match the actual rows for SalesOrderHeader by using an unexpected index on SalesOrderDetail.
You need to improve the performance of the query.
What should you do?
A. Use a FORCESCAN hint in the query.
B. Add a clustered index on SalesOrderId in SalesOrderHeader.
C. Use a FORCESEEK hint in the query.
D. Update statistics on SalesOrderId on both tables.
Correct Answer: D
New statistics would be useful.
The UPDATE STATISTICS command updates query optimization statistics on a table or indexed view. By default, the query optimizer already updates statistics as necessary to improve the query plan; in some cases you can improve query
performance by using UPDATE STATISTICS or the stored procedure sp_updatestats to update statistics more frequently than the default updates.
You have a Microsoft SQL Server instance that has a database named DB1. DB1 has data files on drive E and transaction logs on drive L.
You perform full backups of DB1 daily and transaction log backups hourly.
Drive E fails and is replaced.
You need to recover DB1 and prevent any data loss.
Which four 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:
Section: Deploy and migrate applications
Step 1: Perform a tail-log backup.
A tail-log backup captures any log records that have not yet been backed up (the tail of the log) to prevent work loss and to keep the log chain intact. Before you can recover a SQL Server database to its latest point in time, you must back up
the tail of its transaction log.
The tail-log backup will be the last backup of interest in the recovery plan for the database.
Step 2: Restore a full backup.
Backups must be restored in the order in which they were created. Before you can restore a particular transaction log backup, you must first restore the following previous backups without rolling back uncommitted transactions, that is WITH
The full database backup and the last differential backup, if any, taken before the particular transaction log backup.
Step 3: Restore the log backups.
Log backups must be applied in the sequence in which they were created, without any gaps in the log chain.
Step 4: Restore the tail-log backups.
