QUESTION NO:4
You need to recommend a disaster recovery solution for the Dev database.
What should you include in the recommendation?
A. The simple recovery model and full backups
B. The bulk-logged recovery model and full backups
C. The full recovery model, full backups, and differential backups
D. The full recovery model, full backups, and transaction log backups
Correct Answer: A
Explanation
Explanation/Reference:
* Scenario: 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.
* The simple recovery model provides the simplest form of backup and restore. This recovery model supports both database backups and file backups, but does
not support log backups. Transaction log data is backed up only with the associated user data. The absence of log backups simplifies managing backup and
restore. . However, a database can be restored only to the end of the most recent backup.
Incorrect:
Not B: The bulk-logged recovery model is a special-purpose recovery model that should be used only intermittently to improve the performance of certain large-
scale bulk operations, such as bulk imports of large amounts of data.
QUESTION NO:9
You need to recommend a database reporting solution that meets the business requirements.
What should you include in the recommendation?
A. Data collection
B. Performance Monitor
C. A maintenance plan
D. A dynamic management view
Correct Answer: A
Explanation
Explanation/Reference:
* Scenario: System administrators must be able to run real-time reports on disk usage.
* The data collector provides an historical report for each of the System Data collection sets. Each of the following reports use data that is stored in the
management data warehouse:
Disk Usage Summary
Query Statistics History
Server Activity History
You can use these reports to obtain information for monitoring system capacity and troubleshooting system performance.
QUESTION NO:5
You need to recommend a disaster recovery strategy for the Inventory database.
What should you include in the recommendation?
A. Log shipping
B. SQL Server Failover Clustering
C. AlwaysOn availability groups
D. Peer-to-peer replication
Correct Answer: A
Explanation
Explanation/Reference:
* Scenario:
/ You must be able to recover data from the Inventory database if a storage failure occurs. You have a Recovery Point Objective (RPO) of one hour.
/ A. Datum Corporation has offices in Miami and Montreal.
* SQL Server Log shipping allows you to automatically send transaction log backups from a primary database on a primary server instance to one or more
secondary databases on separate secondary server instances. The transaction log backups are applied to each of the secondary databases individually.
QUESTION NO:23
You administer a SQL Server 2014 instance.
Users report that the SQL Server has seemed slow today. A large database was being restored for much of the day, which could be causing issues.
You want to write a query of the system views that will report the following:
Number of users that have a connection to the server
Whether a user\’s connection is active
Whether any connections are blocked
What queries are being executed
Whether the database restore is still executing and, if it is, what percentage of the restore is complete.
Which system objects should you use in your query to best achieve this task?
A. sys.dm_exec_requests, sys.dm_exec_sessions, sys.objects
B. sys.dm_exec_sessions, sys.dm_exec_query_stats, sys.dm_exec_query_text,sys.objects
C. sys.sysprocesses, sys.dm_exec_query_text, sys.objects
D. sys.dm_exec_requests, sys.dm_exec_sessions, sys.dm_exec_query_text
Correct Answer: D
Explanation
Explanation/Reference:
* sys.dm_exec_requests
Returns information about each request that is executing within SQL Server.
* sys.dm_exec_sessions
Returns one row per authenticated session on SQL Server. sys.dm_exec_sessions is a server- scope view that shows information about all active user
connections and internal tasks. This information includes client version, client program name, client login time, login user, current session setting, and more.
* sys.dm_exec_query_text
Returns the text of the SQL batch that is identified by the specified sql_handle.
Incorrect:
* sys.dm_exec_query_stats
Returns aggregate performance statistics for cached query plans in SQL Server. The view contains one row per query statement within the cached plan, and the
lifetime of the rows are tied to the plan itself.
* sys.objects
Contains a row for each user-defined, schema-scoped object that is created within a database.
QUESTION NO:26
You are designing a database named DB1.
Changes will be deployed to DB1 every Wednesday night.
You need to recommend a strategy to deploy the changes to DB1. The strategy must meet the following requirements:
The strategy must not disrupt backup operations.
DB1 must be online while the changes are deployed.
You must be able to undo quickly any changes made to objects.
What should you recommend?
More than one answer choice may achieve the goal. Select the BEST answer.
A. Perform a copy-only database backup before the changes are deployed. If the deployment fails, restore the database to another server and recover the
original objects from the restored database.
B. Create a database snapshot. If the deployment fails, recover the objects from the database snapshot.
C. Create a database snapshot. If the deployment fails, revert the database to the database snapshot.
D. Perform a full database backup before the changes are deployed. If the deployment fails, restore the database to another server and recover the original
objects from the restored database.

QUESTION NO:18
You are building a stored procedure for a Windows Azure SQL Database. The procedure will add multiple rows to a table.
You need to design the stored procedure to meet the following requirements:
If any of the new rows violates a table constraint, then no further additions must be attempted and all changes made by the stored procedure must be
discarded.
If any errors occur, a row must be added to an audit table, and the original error must be returned to the caller of the stored procedure.
What should you include in the design?
A. An explicit transaction that has XACT_ABORT disabled
B. An implicit transaction that has error handling enabled
C. An explicit transaction that has error handling enabled
