ABC Hospital is planning a Wi-Fi infrastructure upgrade where the 802.11b/g APs (HR/DSSS and ERP)
would be replaced with new dual-radio 802.11n/802.11ac (HT and VHT) APs. ABC wants to minimize the
time and cost associated with performing a new site survey, so they will be mounting all of the new APs in
the same locations and with the same cable drops as the existing APs.

What is one performance drawback with this deployment method?

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

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 nonroot 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.
