Question 31

Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series. You have five servers that run Microsoft Windows 2012 R2. Each server hosts a Microsoft SQL Server instance. The topology for the environment is shown in the following diagram. You have an Always On Availability group named AG1. The details for AG1 are shown in the following table. Instance1 experiences heavy read-write traffic. The instance hosts a database named OperationsMain that is four terabytes (TB) in size. The database has multiple data files and filegroups. One of the filegroups is read_only and is half of the total database size. Instance4 and Instance5 are not part of AG1. Instance4 is engaged in heavy read-write I/O. Instance5 hosts a database named StagedExternal. A nightly BULK INSERT process loads data into an empty table that has a rowstore clustered index and two nonclustered rowstore indexes. You must minimize the growth of the StagedExternal database log file during the BULK INSERT operations and perform point-in-time recovery after the BULK INSERT transaction. Changes made must not interrupt the log backup chain. You plan to add a new instance named Instance6 to a datacenter that is geographically distant from Site1 and Site2. You must minimize latency between the nodes in AG1. All databases use the full recovery model. All backups are written to the network location \\SQLBackup\. A separate process copies backups to an offsite location. You should minimize both the time required to restore the databases and the space required to store backups. The recovery point objective (RPO) for each instance is shown in the following table. Full backups of OperationsMain take longer than six hours to complete. All SQL Server backups use the keyword COMPRESSION. You plan to deploy the following solutions to the environment. The solutions will access a database named DB1 that is part of AG1. ✑ Reporting system: This solution accesses data inDB1with a login that is mapped to a database user that is a member of the db_datareader role. The user has EXECUTE permissions on the database. Queries make no changes to the data. The queries must be load balanced over variable read-only replicas. ✑ Operations system: This solution accesses data inDB1with a login that is mapped to a database user that is a member of the db_datareader and db_datawriter roles. The user has EXECUTE permissions on the database. Queries from the operations system will perform both DDL and DML operations. The wait statistics monitoring requirements for the instances are described in the following table. You need to configure a new replica of AG1 on Instance6. How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-SQL statements to the correct locations. Each Transact-SQL segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. Select and Place:

The wait statistics monitoring requirements for the instances are described in the following table. You need to create a backup plan for Instance4. Which backup plan should you create?

  1. Weekly full backups, nightly differential. No transaction log backups are necessary.
  2. Weekly full backups, nightly differential backups, transaction log backups every 5 minutes.
  3. Weekly full backups, nightly differential backups, transaction log backups every 12 hours.
  4. Weekly full backups, nightly differential backups, nightly transaction log backups.

  4. Modify the full database backups script to stripe the backup across multiple backup files.

Question 34

You have a database. The existing backups for the database and their corresponding files are listed in the following table. You purchase a new server. You must restore the database to the new server. You need to restore the data to the most recent time possible. Which three files should you restore in sequence? To answer, move the appropriate files from the list of files to the answer area and arrange them in the correct order. Select and Place:

Question 35

A Microsoft SQL Server database named DB1 has two filegroups named FG1 and FG2. You implement a backup strategy that creates backups for the filegroups. DB1 experiences a failure. You must restore FG1 and then FG2. You need to ensure that the database remains in the RECOVERING state until the restoration of FG2 completes. After the restoration of FG2 completes, the database must be online. What should you specify when you run the recovery command?

  1. the WITH NORECOVERY clause for FG1 and the WITH RECOVERY clause for FG2
  2. the WITH RECOVERY clause for FG1 and the WITH RECOVERY clause for FG2
  3. the WITH RECOVERY clause for both FG1 and FG2
  4. the WITH NORECOVERY clause for both FG1 and FG2
