SQLAgent jobs are scheduled by the stored procedures in the MSDB database.
Since you are the technical support, you are required to confirm that the stored procedures in the MSDB database should be executed by utilizing the security context of the application user.
Which action should you perform?

A. Each user should be added to the public role in the MSDB database.
B. The MSDB database should be set to utilize the TRUSTWORTHY option, and then each user should be added to the MSDB database.
C. The new database should be set to utilize the TRUSTWORTHY option, and then each user should be added to the MSDB database.
D. Each user should be added to the db_dtsltduser database role in the MSDB database.

Developers in your company have rights to author policies. A test server is used to develop and test the
policies.
The Policy-Based Management feature generates SQL Server Agent alerts when a policy is violated.
The developers are able to create and modify policies, but are unable to test policy violation alerts.

A new database should be deployed, and the capacity requirements listed below should be satisfied.
There should be 275 GB for the database data file, while there should be 50 GB for the transaction log file. There are six 100-GB disk drives which are accessible for the database in the storage array. The six disks are attached to a redundant array of independent disks (RAID) controller, and the controller supports
RAID levels 0, 1, 5, and 10.
Since you are the technical support, you are required to maximize the write performance of the transaction
log. In addition, you should protect the database and transaction log files,
when a drive fails.

The sales team uses portable computers to update data frequently in a local database. When the portable computers connect to the central site, the local database must be synchronized with a database named Sales.
You plan to create a replication model to replicate the local database to the Sales database.
The replication model must meet the following requirements:
Data conflicts are handled when multiple users update the same data independently.
The sales team cannot update sensitive data such as product price.
The sales team can synchronize data at scheduled times and on demand also.
You need to identify the best model to replicate data by using minimum development efforts.
What should you do?

A. Use snapshot replication along with each portable computer that is set up as a subscriber.
B. Use SQL Server Integration Services (SSIS) to push data changes and pull updates to the Sales database along with the SSIS packages, on demand.
C. Use merge replication along with each portable computer that is set up as a subscriber.
D. Use transactional replication along with each portable computer that is set up as a publisher.

Frage #5

Not only a low number of CXPACKET waits but also a large number of lazy writer waits are experienced by the instance. The performance of the instance should be optimized.
Which action will you perform to accomplish the goal?

A. To accomplish the goal, the Resource Governor should be configured.
B. To accomplish the goal, the Windows System Resource Manager should be configured.
C. To accomplish the goal, an increase should be configured in the maximum degree of parallelism option.
D. To accomplish the goal, software non-uniform memory access (soft-NUMA) should be configured.
