Your company uses SQL Server 2005. A user reports that an order processing application stopped responding in the middle of an order transaction. The user’s SQL Server session ID is 54. You need to find out if session 54 is blocked by another connection. If it is, you need to identity the blocking session ID. What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A.
In SQL Server Management Studio, open the Activity Monitor Open the Process Info page. View the BlockedBy column for session 54.

B.
In SQL Server Management Studio, open the Activity Monitor. Open the Locks by Process page. View the Request Mode column for session 54.

C.
In SQL Server Management Studio, open a new query window and execute the following statement.
SELECT *
FROM sys.dm_exec_requests
WHERE session_id = 54
View the blocking_session_id column.

D.
In SQL Server Management Studio, open a new query window and execute the following statement.
SELECT *
FROM sys.dm_exec_sessions
WHERE session_id = 54
View the status column.
