It is best to plan for optimal performance when configuring the PCI devices.\par To provide optimal configuration:\par

  1.

  Match 66MHz slots with 66MHz devices.\par

  2.

  Match 32-bit slots with 32-bit devices.\par

  3.

  For the remaining devices, proceed as follows:\par If you have available 32-bit slots, place the minimum number of 64-bit devices in the 32-bit slots, using the devices with the lowest throughput.\par If you still have more devices than available 64-bit slots, the 66MHz slots will have to run at 33MHz (64- bit).\par }

• Question 43:

  How does single-mode fiber compare with multimode fiber?

  A. Single mode fiber has a higher bandwidth and lower loss.

  B. Multimode fiber has a higher bandwidth and lower loss.

  C. Multimode fiber is more often used for long-distance telecommunications.

  D. Single-mode fiber has higher loss and lower bandwidth.

  Correct Answer: A

The core is so small that only a single mode of light can enter it. Therefore, the chromatic and modal dispersion are greatly reduced or eliminated.\par }

• Question 44:

  Which Linux utility allows you to configure a NIC card?

  A. netstat

  B. ifconfig

  C. sar

  D. ipconfig

  Correct Answer: B

• Question 45:

  Which log contains information about the SUSE Linux startup?

  A. /var/log/boot.log

  B. /var/log/boot.msg

  C. /boot/log/boot.log

  D. /var/opt/log/message.log

  Correct Answer: A

  {\rtf1\ansi\ansicpg936\deff0\deflang1033\deflangfe2052{\fonttbl{\f0\fnil\fcharset0 MS Shell Dlg 2;}} \viewkind4\uc1\pard\lang2052\f0\fs17 Industry Standard Architecture - Student Guide 2 - Page 220\par Red Hat Linux log files are located in the var/log directory. An especially good resource for hardware troubleshooting is the kernel startup file, which is named boot.log. This plain text file can be opened with any text editor. It lists the devices on the system and their status when the system booted. Another useful file is /var/log/messages, which includes boot messages and current system log information.\par }

• Question 46:

  You added memory to a 4-socket AMD Operton-based server. The new memory does not show in POST and the operating system does not see it. You verified that the memory is correct for this server model. Why is the memory not being used?

  A. System Maintanance Switch DIP SW2 is set to ON and the Configuration Lock is enabled.

  B. You exceeded the server's maximum memory capacity.

  C. The memory was added to a bank with no process in the adjoining socket.

  D. There is a memory size mismatch on DR2 and AMD HyperTransport bus.

  Correct Answer: C

• Question 47:

  A customer complains about server performance. Performance parameters show the following information:

  Network Segment: % Network Utilization - 55%

  Page/Sec - 7

  % Processor Time - 55%

  % Disk Time - 35%

  A. disk

  B. network

  C. memory

  D. processor

  Correct Answer: C

Hard page faults occur when a process requires code or data that is not in its working set or elsewhere in physical memory, and must be retrieved from disk.\par On most servers, if this value is consistently greater than 5, it indicates an excessive amount of paging. Try to identify the application that is creating the paging condition. If this is not normal behavior for the application, adding memory might increase system performance.\par }

• Question 48:

  All the RAID sets in a server system are no longer accessible. Which step should be taken first to troubleshoot this problem?

  A. Replace the array controller.

  B. Pull all the disks except one in orer to get a lease on working.

  C. Start the system with the OS installation CD to repartition the hard drives.

  D. Use the array controller diagnostics utility to verify the array status.

  Correct Answer: D

• Question 49:

  After some analysis, you determine that more memory is needed to address a system bottleneck. How do you increase the memory and ensure the additional resources are effective to meet the need?

  A. Add the memory and monitor perform counter % Usage Peak to verify that it is < 75%

  B. Add the memory and increase the amount of the Paging File to equal the total amount of memory installed plus 10%

  C. Establish a baseline performance report, install the new memory, create a new baseline report and compare it against expectations and the first baseline.

  D. Run Task Manager to check the amount of physical memory available, add the new memory and confirm the addition by running Task Manager again to show the new resources.
