1. An endeavor campus LAN uses wired UTP Ethernet and wireless 802. 11 LANs at the border of the LAN. Looking at a peculiar floor in a peculiar edifice. all the devices connect to either a individual Ethernet switch or individual wireless entree point. both of which sit in a wiring cupboard in the center of the infinite. Which of the undermentioned is true about the distance restrictions in this LAN? C. All Ethernet user devices can be up to 100 metres off ( but no farther ) . while WLAN devices must typically be closer than 100 metres.
2. IEEE 802. 11 criterions specify a maximal velocity for an single transmittal. with some variables that affect 802. 11n velocities. Assuming that 802. 11n uses the narrower 20-MHz channel and a individual watercourse. which of the undermentioned replies matches a peculiar criterion to its maximal spot rate? A. 802. 11g: 54 Mbps
3. An endeavor campus LAN uses wired UTP Ethernet and wireless 802. 11 LANs at the border of the LAN. A web applied scientist uses a WLAN proving tool to see the frames traveling through the WLAN. and he notes the velocities of the assorted frames in a individual WLAN that uses a individual entree point. Which of the undermentioned replies list a status that could hold affected the velocities that the applied scientist observed when proving the WLAN? ( Choose two answers. ) B. The current wireless noise.
D. Whether the AP uses CSMA/CA.
4. An endeavor campus WLAN uses a individual 802. 11n AP. with 20 clients that all use 802. 11n. The AP uses merely a individual watercourse. but it does utilize a double-wide channel. with a maximal information rate for a individual transmittal of 150 Mbps. The same floor has an Ethernet LAN. with 20 PCsconnected utilizing 10BASE-T. UTP cabling. The Ethernet switch and AP both connect to the remainder of the web utilizing a Gigabit Ethernet interface. Which of the undermentioned statements are true when comparing the wired and wireless LANs on this floor? ( Choose two answers. ) B. The radio LAN has a larger capacity
D. A individual transmittal from the AP to a WLAN user device goes faster than the transmittal from the Ethernet switch to a wired user device. 5. A web applied scientist is planing a campus LAN. both wired and radio. When be aftering the radio LAN. the applied scientist looks at a scale drawing of the infinite for each floor and draws the coverage country associated with each AP.
