单选题 A company wants to replace their Dell servers and implement x445 servers with a Storage Area Network (SAN).  They will add an IBM TotalStorage DS4500 and EXP710s for their storage requirements.  The customer’s goal is to reduce the Total Cost of Ownership (TCO) of their current environment.  Which of the following factors provide the greatest advantage?()

A

The DS4500 with DS4000 Storage Manager provides efficient storage utilization.

B

The DS4500 and x445 provide disaster recovery capability.

C

The IBM TotalStorage DS4500 includes virtualization of the disk storage.

D

Storage partitioning and Remote Volume Mirroring are standard features with the DS4500 product.

单选题 A customer has a file server with RAID-5 using 8KB random I/Os, with 67% reads and 33% writes.  How should the disk controller cache be configured for optimal performance?()

A

Use write-back cache

B

Use write-back cache with battery backup

C

Use write-through cache with disk caching enabled

D

Use write-through cache with disk caching disabled

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?()

A

Implement one DS4400 at each location connected to the fibre link and use Remote Volume Mirror (RVM).

B

Implement a DS4400 at each location using FlashCopy option and use host based replication to synchronize the sites.

C

Implement a switched fabric using redundant SAN switches with a DS4300 using RVM option at each location.

D

Implement a switched fabric using SAN switches connected via ISL with a DS4300 using RVM option at each location.

多选题 Which TWO of the following are required to use the hot-swap memory feature of the x445 while being operating system independent?()

A

Memory Mirroring must be enabled in the BIOS.

B

Redundant bit steering must be enabled in the BIOS.

C

DIMMs must be the same size and speed as the DIMMs being replaced.

D

Memory Mirroring must be enabled in the operating system.

E

DIMMs can be of same size or larger or same speed or faster.

单选题 A customer uses an IBM xSeries x366.  They experienced downtime when the NIC failed earlier this year.  Their Windows 2003 server needs to be accessible all the time, at the highest speed possible.  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?()

A

Install four NICs and configure load balancing adapter teaming.

B

Install four NICs and configure adapter failover teaming.

C

Install seven NICs and configure load balancing adapter teaming.

D

Install one extra NIC to team with the internal adapter and configure failover teaming.
