Two adapters are currently installed in the x366. Which of the following is the procedure to obtain the best performance and ensure network functionality in case of NIC failure？（）
Install four NICs and configure load balancing adapter teaming.
Install four NICs and configure adapter failover teaming.
Install seven NICs and configure load balancing adapter teaming.
Install one extra NIC to team with the internal adapter and configure failover teaming.
单选题 A customer is considering replacement of twenty older 4U and 6U rack-based servers with one IBM x366 Server running VMWare ESX attached to one DS4300. Which of the following represents a reduction in Total Cost of Ownership （TCO） for the customer？（）
Reduction in operating system software licensing and application costs
Reduction in floor space and hardware cost saving
VMWare is licensed per system so no extra charge for SMP support
No single point of failure， reducing downtime
单选题 A company wants a solution to consolidate their storage using the DS4000 series and implement a disaster recovery solution across two data centers linked by fibre to duplicate the production environment.The customer requires a solution with the least amount of system administration. Which configuration would provide the best solution？（）

单选题 A small bio-technical company is interested in implementing a 32-node Linux cluster. They developed their own software that allows all of the nodes to work on the same problem at the same time. The application requires messages to be passed between the nodes. Each node will require access to a shared storage pool of around 500GB. To identify throughput requirements for the storage pool， which of the following is the most appropriate question to ask？（）
Is high availability required？
Which network protocols are going to be used？
What are the expected I/O’s per second to the storage？
To what network infrastructure is the storage pool connected？
单选题 A customer is building a database server， and the server does sequential write most of the time. They are planning to use an IBM x445 and a ServeRAID-6M adapter. Which of the following fault tolerant RAID levels will perform best for sequential write？（）
RAID-5 with cache write back
RAID-1E with cache write back
RAID-10 with cache write thru
RAID-50 with cache write thru
It places frequently accessed data close to the processor to help deliver faster performance.
It replaces L3 cache memory.
It speeds up processor performance by purging the current set of instructions and freeing them up to work on the next set of instructions.
It allows the system to address more than 16GB of memory.
Your network consists of a single Active Directory domain. The domain contains more than 300 group objects. The group objects are divided between several regional organizational units (OUs).
