Answer These Questions
1. An enterprise campus LAN uses wired UTP Ethernet and wireless 802.11LANs at the edge of the LAN. Looking at a particular floor in a particular building, all the devices connect to either a single Ethernet switch or single wireless access point, both of which sit in a wiring closet in the middle of the space. Which of the following is true about the distance limitations in this LAN?
We already know that UTP Ethernet has a maximum cable length limit of 100 meters. Generally, Wireless Access Points have a transmission distance limitations less than that of UTP Ethernet cabling.
C
2. IEEE 802.11 standards define a maximum speed for an individual transmission, with some variables that affect 802.11n speeds. Assuming that 802.11n uses the narrower 20-MHz channel and a single stream, which of the following answers matches a particular standard to its maximum bit rate?
C
3. An enterprise campus LAN uses wired UTP Ethernet and wireless 802.11 LANs at the edge of the LAN. A network engineer uses a WLAN testing tool to view the frames moving through the WLAN, and he notes the speeds of the various frames in a single WLAN that uses a single access point. Which of the following answers list a condition that could have affected the speeds that the engineer observed when testing the WLAN? (Choose two answers.)
B AND D
4. An enterprise campus WLAN uses a single 802.11n AP, with 20 clients that all use 802.11n. The AP uses only a single stream, but it does use a doublewide channel, with a maximum data rate for a single transmission of 150 Mbps. The same floor has an Ethernet LAN, with 20 PCs connected using 10BASE-T, UTP cabling. The Ethernet switch and AP both connect to the rest of the network using a Gigabit Ethernet interface. Which of the following statements are true when comparing the wired and wireless LANs on this floor? (Choose two answers.)
