It sends a packet of data to the other network device that you have specified by providing its IP address. If a reply is returned to you, connectivity is confirmed. If you do not get a reply, either your device or the one you tried to contact are not available to the network. The command output also reports how long the reply took, which can indicate the level of traffic congestion.\par }

  Correct Answer: B

  {\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 1 - Page 124:\par Bank interleaving\par SDRAM divides memory into two to four banks for simultaneous access to more data.\par This division and simultaneous access is known as interleaving.\par In two-way interleaving while one memory bank is being accessed, the other bank remains ready to be accessed. Thus the processor can initiate a new memory access before the previous access has been completed, resulting in continuous data flow and increasing the amount of data accessed in a single memory access. \par When data is written to memory, the memory controller distributes the data across DIMMs in a bank. When the processor sends a read request to the memory controller, the memory controller sends the request to all DIMMs in the bank simultaneously. The data at the requested address is returned along with data from subsequent sequential addresses. The memory controller interleaves the data from all the DIMMs to put it back in its original order.\par Because more than one DIMM is used in this transaction, the amount of data that can be written or read is larger than if a single DIMM were used. For example, in dual-interleaved memory, where two DIMMs are used, the processor can read and write twice the amount of data in one memory access. In four-way interleaved memory, the processor can read and write four times the amount of data in one memory access.\par }

A hot-plug system requires a hot-plug platform, a hotplug operating system, and hot-plug adapter drivers.\par }

• Question 40:

  What must you check prior to adding another processor to an existing system? (Select Three)

  A. amount of memory in the system

  B. compatibility of the new processor with existing processors

  C. firmware requirements for the new processor

  D. number of users currently logged into the system

A requirement for multi-processor systems is compatibility of the new processor with the existing processors. \par Operating system update or reconfiguration\par On a multi-processor server, the operating system must be capable of handling more than one processor. If the OS version does not support more than one processor, it must be updated to a version that does support multiple processors.\par BIOS update\par It usually is necessary to update the system BIOS to support the increased speed or cache size of a new processor. Once again, it is necessary to check the documentation provided by the server manufacturers, who often provide new BIOS versions on their web sites.\par }
