QUESTION: 6

A database administrator is conducting a stress test and providing feedback to a team that is developing an application that uses the Entity Framework.
Which of the following explains the approach the administrator should use when conducting the stress test?

Capture business logic, check the performance of codes, and report findings.
Check the clustered and non-clustered indexes, and report findings.
Review application tables and columns, and report findings.
Write queries directly into the database and report findings.

Answer(s): A

Explanation:

The approach that the administrator should use when conducting the stress test is to capture business logic, check the performance of codes, and report findings. This will help the administrator to evaluate how well the application handles high volumes of data and transactions, identify any bottlenecks or errors in the code, and provide feedback to the development team on how to improve the application's efficiency and reliability. The other options are either too narrow or too broad in scope, and do not address the specific needs of an application that uses the Entity Framework.

QUESTION: 10

A company wants to deploy a new application that will distribute the workload to five different database instances. The database administrator needs to ensure that, for each copy of the database, users are able to read and write data that will be synchronized across all of the instances.

Which of the following should the administrator use to achieve this objective?

[Peer-to-peer replication
Failover clustering
Log shipping
Availability groups

Answer(s): A

Explanation:

The administrator should use peer-to-peer replication to achieve this objective. Peer-to-peer replication is a type of replication that allows data to be distributed across multiple database instances that are equal partners, or peers. Each peer can read and write data that will be synchronized across all peers. This provides high availability, scalability, and load balancing for the application. The other options are either not suitable for this scenario or do not support bidirectional data synchronization. For example, failover clustering provides high availability but does not distribute the workload across multiple instances; log shipping provides disaster recovery but does not allow writing data to secondary instances; availability groups provide high availability and read- only access to secondary replicas but do not support peer-to-peer replication.
