The database uses the simple-recovery model.
The database contains the following three additional filegroups:
FileGroupA that is read/write
FileGroupB that is read-only
FileGroupC that is read-only
FilegroupB contains less critical data than FilegroupC.
You discover that the PRIMARY filegroup and FileGroupB have failed.
You need to recover the database in the minimum possible time. You also need to ensure that
data is available as soon as possible.
What should you do?
A) Perform a partial restore of the PRIMARY filegroup and FileGroupB from a partial backup.
B) Perform a partial restore of the PRIMARY filegroup and FileGroupA from a partial backup. Perform an online recovery of FileGroupB, and then perform an online restore of FileGroup
C) Perform a full database restore.
D) Perform a partial restore of the PRIMARY filegroup and FileGroupA from a partial backup. Perform an online recovery of FileGroupC, and then perform an online restore of FileGroupB.
2. You administer a SQL Server 2008 infrastructure.
The instance contains a database required for the day-to-day business of your company. Users experience slow response time when they execute reports.
You plan to design a performance monitoring strategy that captures and stores the following data:
Executed Transact-SQL statements and query activity.
Blocking and deadlock information.
Counters for disk, CPU, and memory.
You need to implement the monitoring process by using the minimum amount of administrative effort.
What should you do?
A) Use the data collector

D) Use the client-side profiler trace.
3. You are a professional level SQL Sever 2008 Database Administrator.
A maintenance strategy should be designed for a mission-critical database, and a large table named Orders is contained by the database. Index maintenance operations are contained in the design plan. When you design the strategy, the facts listed below should be taken into consideration.
First, the users continuously access to the Orders table in the database.
Secondly, a column of the xml data type is contained by Orders table.
Thirdly, the new rows are regularly added to the Orders table.
Fourthly, the average fragmentation for the clustered index of the Orders table is no more than 2
percent.
A strategy should be designed to have the performance of the queries on the table optimized.
Which action will you perform?
A) The clustered index of the Orders table should be excluded from scheduled reorganizing or rebuilding operations.
B) The clustered index of the Orders table should be reorganized by reducing the fill factor.
C) The clustered index of the Orders table offline should be rebuilt once a month.
D) The clustered index of the Orders table should be dropped.
4. You administer a SQL Server 2008 instance that hosts a large database.
The following backup strategy is used for the database:
A full database backup is performed at 02:00 hr every Monday.
A differential backup is performed at 23:00 hr every day.
A transaction log backup is performed on an hourly basis.
