Networking Professional Questions For Fun?

#1) State the OSI MODEL Mnemonic Layers 1-7 as defined in Network+





#2) What is the difference between Standards 802.3 and 802.11?





#3) Define Plenum in your own words?





#4) What is the average size Router, Firewall, Switch, Patch Panel mounting rack width?





#5) State the Network-Type Fiber Application listed for these specifications:


SINGLE MODE-Wavelength/Size


1300nm - 8/125-Micron


1550nm - 8/125-Micron


MULTI-MODE-Wavelength/Size


850nm 62.5/125 or 50/125-Micron


1300nm 62.5/125 or 50/125-Micron


HINT! Options are: Ethernet, Fast Ethernet, Gigabit Ethernet, 10GBase, Token Ring, ATM155Mbps, and FDDI.





I'm out of "Answers" today only at level 1, so I figured I would make a fun questionaire for the networking professionals. Like myself whom enjoys a network challenge, you can too... lol.

This looks like homework but I 'll answer but you need to learn the answers if you are going to pass the course or networking test.





#1) State the OSI MODEL Mnemonic Layers 1-7 as defined in Network+


1.Physical 2. Data Link 3. Network 4. Transport 5. Session 6. Presentation 7. Application





#2) What is the difference between Standards 802.3 and 802.11?


802.11b wireless LAN (WLAN) standard is similar to that for IEEE 802.3 (Ethernet) LAN. Good article on WIkepedia





#3) Define Plenum in your own words? Plenum cable is coated with fire resistant coating. A Plenum space is the air space in a floor or ceiling.





#4) What is the average size Router, Firewall, Switch, Patch Panel mounting rack width? 19 inches. Just got up and measured.





#5) State the Network-Type Fiber Application listed for these specifications:


SINGLE MODE-Wavelength/Size


SINGLE MODE-Wavelength/Size


1550nm - 8/125-Micron


MULTI-MODE-Wavelength/Size


850nm 62.5/125 or 50/125-Micron


1300nm 62.5/125 or 50/125-Micron





Multimode fiber is best designed for short transmission distances, and is suited for use in LAN systems and video surveillance. Single-mode fiber is best designed for longer transmission distances, making it suitable for long-distance telephony and multichannel television broadcast systems.
