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 customer’s server is experiencing slow application response due to lack of processor power. In which one of the following systems would the addition of the Expand On Demand processor upgrade feature benefit future expansion?()
An x255 with 4 processors
An x365 with 4 processors
An x445 with 4 processors
An x445 with 32 processors
单选题 Which of the following is a function of the XceL4 Cache?()
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.
多选题 A customer runs an application on a supported 8-way x445. The customer needs to monitor operations and wants to be alerted when problems arise. Which TWO of the following can be configured in IBM Director Base Pack to monitor the customer’s operations?()
Fan operation
Bottleneck analysis
Power supply operations
Planned versus unplanned outages
Application predictive failure analysis
单选题 A customer needs a new database server. Their third-party application requires Microsoft SQL Server. They have 100 users who will login to the network and store their data files on the network server. They will also require the server to be an email server and to deploy a central antivirus solution. Which of the following network operating systems would satisfy these requirements?()
SuSE Linux Enterprise 9
Red Hat Linux Advanced Server 3
Microsoft Windows 2003 Server Web Edition
Microsoft Windows 2003 Server Standard Edition
单选题 A customer needs the ability to recover their data if a total system failure occurs. Which two of the following are the most important considerations in determining the solution?()
Network utilization
Total amount of storage installed
Amount of open files in the backup
Amount of critical data in the backup or restore
单选题 The statistics for a poorly performing, dual-processor x365 system are as follows: (1)Processor: 80% for 5-second increments (2)Memory page faults: 360/second average over 15 minutes (3)Disk % disk time: 100% Which of the following will provide the greatest performance improvement?()
Add memory
Add a processor
Exchange the existing processor for a faster processor
Add a faster disk subsystem
单选题 Some xSeries servers support 4-way memory interleaving and some support 2-way interleaving. In both types of interleaving, the data is accessed 256 bits at a time. How is this 256-bit data access achieved with 2-way interleaving?()
The DIMMs used for 2-way interleaving are double the width of DIMM used in 4-way interleaving.
The DIMMs used for 2-way interleaving are 64-bit wide and data bits are accessed both on the rising edge and falling edge of the clock cycle.
The DIMMs used for 2-way interleaving are 32-bit wide and data bits are accessed both on the rising edge and falling edge of the clock cycle.
The DIMMs used for 2-way interleaving are double the width and data bits are accessed both on the rising edge and falling edge of the clock cycle.
单选题 Due to the pricing of MP processors, a customer is evaluating DP processors. They have current budget constraints and do not want to discard obsolete hardware after a scaling step. It is calculated that two processors will meet their immediate needs. Their projected growth indicates they will need more than four processors. Which of the following recommendations will provide the best path for growth at the lowest cost?()
Begin with a dual DP x445 and scale in the same chassis
Begin with a dual MP x445 and scale in the same chassis
Begin with a dual DP x445 and scale out in an extra chassis
Begin with a dual MP x365 and scale to a different machine
