第6题:
You are the administrator of a SQL Server 2000 computer. The server contains your company's order processing database. Two-hundred operators take orders by telephone 24 hours a day. Threehundred data entry personnel enter data from orders received by mail.
To ensure that order data will not be lost, your company's disaster recovery policy requires that backups be written to tape. Copies of these tapes must be stored at an off-site company location. Orders must be entered into the database before they can be filled. If the server fails, you must be able to recover the order data as quickly as possible.
You need to create a backup strategy that meets the company requirements and minimizes server workload. Which two actions should you take? (Each correct answer represents part of the solution. Choose two.)
A.Perform. a combination of full database and filegroup backups.
B.Perform. a combination of full database and file backups.
C.Perform. a combination of full database, differential, and transaction log backups.
D.Back up the data to a local tape drive.
E.Back up the data to a network share, and then use enterprise backup software to write the disk backups to tape.
第7题:
A company needs to implement an offsite backup method that is replicated and needs toguarantee that the data cannot be changed once it is replicated. Which of the following would meet the company’s needs?()
第8题:
A.Both technologies guarantee an identical copy of data on the secondary node
B.Only MySQL can maintain a time-delayed copy of data on the secondary node
C.Both technologies use the TCP/IP stack as their primary transmission medium

第9题:
You work in a company which is named Wiikigo Corp. The company uses SQL Server 2008. You are the administrator of the company database. Now you are in charge of a SQL Server 2008 instance. There is a database named Dworks in the instance. The Dworks database has the Products table. Now you have to replicate the Products table to the SQL Server instances at remote locations, so you create a Merge Replication topology and a Publication to do this. The Publication has a 21-day retention period. There is a user who goes on a business trip, 30 days later he comes back and finds that data in his database is not the latest. The Windows Event log states the following error message: "Replication: expired subscription dropped." You must get the latest data in the user's database and make sure that future data changes are appropriately replicated. So what action should you perform to achieve this goal? ()
