You administer a Microsoft SQL Server 2012 database named Orders.
Users report that during peak usage periods, certain operations are taking more time than expected. Your initial analysis suggests that blocking is the cause.
You need to gather more data to be able to determine which processes are being blocked and to identify the root cause.
What should you do?

• A.Use Sp_Configure to set the blocked process threshold. Start a Trace using SQL Server Profiler to catch the Blocking Pro-Report event.
• B.Start a Trace using SQL Server Profiler to catch the Lock: Timeout event
• C.Use System Monitor to catch the Lock Wait Time event
• D.Schedule A SQL Agent job to run every 60 Seconds and insert the results of executing the SP_who2 stored procedure table

HOTSPOT
----
You administer a Microsoft SQL Server 2012 database instance.
The instance is running on a server with the following configuration:
1TB RAM
SAN storage for database and log files
4 quad-core processors
64-Bit Windows 2008R2 operating system
This instance hosts a database with large partitioned tables. Users report that complex queries are taking a long time to complete.
While troubleshooting, you discover that CPU utilization is low (less than 20 percent), disk activity is low (little or no waiting processes), and no significant blocking is occurring.
You need to ensure that the instance can process queries as quickly and efficiently as possible.
Which setting should you configure?

DRAG DROP
You administer a Microsoft SQL Server 2012 database.
All database traffic to the SQL Server must be encrypted by using secure socket layer (SSL) certificates or the connection must be refused.
Network administrators have deployed server certificates to the Windows store of all Windows servers on the network from a trusted Certificate Authority. This is the only Certificate Authority allowed to distribute certificates on the network.
You enable the Force Encryption flag for the MSSQLServer protocols, but client computers are unable to connect. They receive the following error message:
"A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) (Microsoft SQL Server)" You notice the following entry in the SQL Server log:
"A self-generated certificate was successfully loaded for encryption."
You need to configure SQL Server to encrypt all client traffic across the network.
You also need to ensure that client computers are able to connect to the server by using a trusted certificate.

You administer several Microsoft SQL Server 2012 database servers.
Merge replication has been configured for an application that is distributed across offices throughout a wide area network (WAN). Many of the tables involved in replication use the XML and varchar(max) data types. Occasionally, merge
replication fails due to timeout errors.
You need to reduce the occurrence of these timeout errors. What should you do?

• A.Set the Merge agent on the problem subscribers to use the slow link agent profile.
• B.Create a snapshot publication, and reconfigure the problem subscribers to use the snapshot publication.
• C.Change the Merge agent on the problem subscribers to run continuously.
• D.Set the Remote Connection Timeout on the Publisher to 0.
