You implement log shipping for several databases on three SQL Server instances. The logs are shipped to a fourth SQL Server instance. You plan a manual failover.
You need to ensure that the database applications use the secondary server after failover. You also need to ensure that users can access the most recent data.
Which three tasks should you perform? (Each correct answer presents part of the solution. Choose three.)
A) Back up all databases on the secondary instance.
B) Apply any unapplied transaction log backups in sequence to each secondary database by using the WITH RECOVERY option on the last log.
C) Copy all log shipping network shares to the secondary instance.
D) Back up the tail of the transaction log of primary databases by using the WITH NORECOVERY option.
E) Redirect client computers to the secondary instance.
2. You are a professional level SQL Sever 2008 Database Administrator.
They are respectively named Ins01, Ins02, Ins03 and Ins04. A single database application is hosted by each instance. All four instances should be removed to a new SQL Server failover cluster. You can see the configuration of the four instances from the table listed below:
All the four instances are sufficiently optimized, and there are no spare CPU cycles or extra memory in
the instances.
All four databases will be hosted by the new cluster on a single virtual cluster IP address.
Since you are the technical support, you are required to set the new cluster to handle the workload of all the database applications with the least amount of hardware resources.
From the four cluster configuration, which one should be utilized?
A) Two-node active/passive cluster should be utilized and a minimum of 18 processors and a 50-GB memory are contained by each node.
B) Four-node active/active/active/passive cluster should be utilized and a minimum of 18 processors and a 50-GB memory are contained by each node.
C) Two-node active/active cluster should be utilized and a minimum of 9 processors and a 25-GB memory are contained by each node.
D) Four-node active/active/active/active cluster should be utilized and a minimum of 9 processors and a 25-GB memory are contained by each node.
3. You administer a SQL Server 2008 infrastructure.
An instance runs on a computer that has eight quad-core processors and 128-GB RAM.

Minimize data loss in the event of a server failure.
You need to provide a high-availability solution that meets the business requirements.
Which solution should you implement?
A) Asynchronous database mirroring without a witness server
B) Log shipping to servers at two of the sites to provide read-only copies of data
C) Peer-to-Peer replication
D) Failover clustering
5. You administer a SQL Server 2008 infrastructure.
You plan to deploy a new SQL Server 2008 multi-node failover cluster. The failover cluster uses a storage
area network (SAN)
that will use redundant array of independent disks (RAID) level 5.
