7、2.4 Run as a virtual server installed on a PC hard disk drive,Option 1,1.1Bootable CD-ROM (ISO) - Run from the CDThe CD contains a bootable Linux file system.Runs network services directly from RAM on the PC on which

8、 it boots.Very Flexible: PC lab resources can be shared with non-CCNA classes or courses. Any available PC meeting the specifications can temporarily act as the server for the duration of the class. But: Any modi

9、fications made to the Server are lost when the computer is rebooted.,Option 2,1.2Permanent ServerThe file system may be installed on a Linux or Windows FAT partition on the hard disk drive of a PC available to be perma

10、nently used as the server. A permanent installation enables any modifications made to the server to be retained when the computer is rebooted and re-used in later labs. Facilitates local server development and custom

11、ization. Enables local backup copies of IOS images, configurations and class resources to be stored for future use.But: Requires dedicated PC or partition on a PC hard drive.,Option 3,2.1Run from the saved VMware i

12、mageCompressed VMware image (RAR file) of server ISODownloaded and deployed using VMware. Enables use of different lab and classroom computer resources that are available at different times.  The server runs as

13、virtual server on a PC running VMware Player. Very flexible, but:Requires VMware Player to be installed and running on PCChanges made to the server do not persist when the virtual server is restarted.,Option 4,2.2Ru
