QUESTION 10
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.
Correct Answer: A
When replication is configured, a set of agent profiles is installed on the Distributor. An agent profile contains a set of
parameters that are used each time an agent runs: each agent logs in to the Distributor during its startup process and
queries for the parameters in its profile. For merge subscriptions that use Web synchronization, profiles are downloaded
and stored at the Subscriber. If the profile is changed, the profile at the Subscriber is updated the next time the Merge
Agent runs. For more information about Web synchronization, see Web Synchronization for Merge Replication.
Replication provides a default profile for each agent and additional predefined profiles for the Log Reader Agent,
Distribution Agent, and Merge Agent. In addition to the profiles provided, you can create profiles suited to your
application requirements. An agent profile allows you to change key parameters easily for all agents associated with that
profile. For example, if you have 20 Snapshot Agents and need to change the query timeout value (the – QueryTimeout
parameter), you can update the profile used by the Snapshot Agents and all agents of that type will begin using the new
value automatically the next time they run. You might also have different profiles for different instances of an agent. For
example, a Merge Agent that connects to the Publisher and Distributor over a dialup connection could use a set of
parameters that are better suited to the slower communications link by using the slow link profile.


QUESTION 11
You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a storage area
network (SAN).
The financial database has the following characteristics:
A data file of 2 terabytes is located on a dedicated LUN (drive D). A transaction log of 10 GB is located on a dedicated
LUN (drive E).
Drive D has 1 terabyte of free disk space.
Drive E has 5 GB of free disk space.
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 the backup size is as small as possible.
Which backup should you perform every two hours?
A. BULK_LOGGED
B. NO_CHECKSUM
C. FULL
D. RESTART
E. CHECKSUM
F. STANDBY
G. DBO.ONLY
H. NORECOVERY
I. SIMPLE
J. SKIP
K. Transaction log
L. COPY_ONLY
M. Differential
N. CONTINUE_AFTER_ERROR
Correct Answer: K
