You are the SQL administrator for your company. A SQL Server 2008 instance named SQL3 contains a databasenamed Sales.
The Sales database is accessed throughout the day. You need to monitor the amount of I/O generated by the instance.
Which two performance monitor counters should you monitor? (Choose two. Each correct answer represents partof the solution.)

A.
SQLServer: Databases: Transactions/sec

B.
SQLServer: Databases: Write Transactions/sec

C.
SQL Server: Buffer Manager: Page reads/sec

D.
SQL Server: Buffer Manager: Page writes/sec

E.
SQL Server: General Statistics: Logins/sec

F.
SQL Server: General Statistics: Logouts/sec

Explanation:

You should use the SQL Server: Buffer Manager: Page reads/sec and SQL Server: Buffer Manager: Pagewrites/sec counters to monitor the amount of I/O generated by the instance. These counters are helpful whenmonitoring disk usage. All of the other options are incorrect because none of these counters would be helpful in determining the amountof I/O generated by the instance. The SQLServer: Databases: Transactions/sec counter displays the number oftransactions started each second. The SQLServer: Databases: Write Transactions/sec counter displays thenumber of write transactions committed each second. The SQL Server: General Statistics: Logins/sec counterdisplays the total number of logins per second. The
SQL Server: General Statistics: Logouts/sec counterdisplays the total number of logouts per second.
