What is one performance drawback with this deployment method?
Given: ABC Hospital is planning a Wi-Fi infrastructure upgrade where the 802.11b/g APs would be
replaced with new dual-radio HT (802.11n) 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 the reason for this recommendation?
Given: In a single channel architecture (SCA) WLAN system, 802.11n (HT) APs should not share
an SSID with 802.11g (ERP) APs.
What is the reason for this recommendation?
Which unit of measurement is a relative unit that is used to quantify power level changes?
Which unit of measurement is a relative unit that is used to quantify power level changes?
What causes high return loss in an RF transmission system?
Given: Return Loss is the decrease of forward energy in a system when some of the power is
being reflected back toward the transmitter.
What causes high return loss in an RF transmission system?

What factor is NOT taken into account when calculating the Link Budget of a point-to-point outdoor WLAN bridge
What factor is NOT taken into account when calculating the Link Budget of a point-to-point outdoor
WLAN bridge link?
What device in the bridge implementation acts as the 802.1X Authenticator?
ABC Company is planning a point-to-multipoint outdoor bridge deployment with standalone
(autonomous) 802.11 bridge units. 802.1X/EAP will be used for bridge authentication. What device
in the bridge implementation acts as the 802.1X Authenticator?
What is true of the two lower bands (UNII-1 and UNII-2) in this frequency spectrum?
The IEEE 802.11a/n physical layer technologies utilize the 5 GHz frequency band. What is true of
the two lower bands (UNII-1 and UNII-2) in this frequency spectrum? (Choose two)
What deployment flaw could cause this problem?
Given: Two co-located 802.11b/g/n APs can interfere with one another and cause contention and
collisions, even when the two APs are operating on non-overlapping channels (e.g. 1 & 6).
What deployment flaw could cause this problem? (Choose two)
