In an 802.11n WLAN with a heterogeneous set of associated client devices including 802.11b,
11g, and 11n, what HT protection mode will the BSS use?

Given: As you prepare for a site survey in a hospital, you have learned about several wireless
devices that support connection-oriented, real-time applications. These applications are sensitive
to service interruptions and require excellent signal quality, low latency, and low loss. For that
reason, it is important to identify sources of RF interference as well as building characteristics that
would cause RF blockage or dead spots.
What systems or environmental characteristics are most likely to cause interference or RF
blockage and disrupt service for these applications? (Choose two)

What term correctly completes the following sentence?
In an IEEE 802.11 frame, the IP packet is considered by the MAC layer to be a(n) _________.

What factors are likely to cause the greatest impact on the application layer throughput of an
802.11n client station in a 2.4 GHz HT BSS? (Choose three)

Given: Joe runs a small hotel, and as a value added service for his customers he has
implemented a Wi-Fi hot-spot. Joe has read news articles about how hackers wait at hot-spots
trying to take advantage of unsuspecting users. Joe wants to avoid this problem at his hotel.
What is an efficient and practical step that Joe can take to decrease the likelihood of active attacks
on his customers’ wireless computers?

What factors will have the most significant affect on the amount of wireless bandwidth available to
each station within a BSS? (Choose two)

What features were introduced in the IEEE 802.11h amendment in order to uphold regulatory
requirements for 5 GHz operation? (Choose two)

What statements about the SSID are true? (Choose two)

What statements describe industry practices for communication protocols between WLAN
controllers and controller-based APs? (Choose two)

Given:
As a consultant, you have been hired by ABC Company to implement an outdoor WLAN
connection between two buildings that are 2 kilometers (1.24 miles) from each other, with no
obstructions in between.
Your first required objective is to create a point-to-point link between the two buildings within the
local regulatory body’s 800 mW EIRP maximum.
Your second required objective is to provide an industry-standard security solution capable of
supporting mutual authentication.
As an optional objective, you must minimize the amount of interference from, and to, nearby
WLAN networks.
You install an OFDM wireless bridge at each building, configuring one in root mode and the other
in non-root mode. You set each radio for 100 mW (20 dBm) and attach 9 dBi omni-directional
antennas to both. You configure the network for WPA2-Enterprise with PEAPv0/EAP-MSCHAPv2
authentication.
Which statement is true about the solution you chose to deploy?
