Question 66

You administer a Microsoft SQL Server 2016 server that hosts a transactional database and a reporting database. The transactional database is updated through a web application and is operational throughout the day. The reporting database is only updated from the transactional database. The recovery model and backup schedule are configured as shown in the following table: At 14:00 hours, you discover that pages 71, 520, and 713 on one of the database files are corrupted on the reporting database. You need to ensure that the databases are restored. You also need to ensure that data loss is minimal. What should you do?

  1. Perform a partial restore.
  2. Restore the latest full backup, and restore the latest differential backup. Then, restore each log backup taken before the time of failure from the most recent differential backup.
  3. Restore the latest full backup.
  4. Restore the latest full backup, and restore the latest differential backup. Then, restore the latest log backup.
  5. Perform a page restore.
  6. Restore the latest full backup. Then, restore each differential backup taken before the time of failure from the most recent full backup.
  7. Perform a point-in-time restore.
  8. Restore the latest full backup. Then, restore the latest differential backup.

Question 68

You administer several Microsoft SQL Server 2016 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?

  1. Set the Merge agent on the problem subscribers to use the slow link agent profile.
  2. Create a snapshot publication, and reconfigure the problem subscribers to use the snapshot publication.
  3. Change the Merge agent on the problem subscribers to run continuously.
  4. Set the Remote Connection Timeout on the Publisher to 0.
