In a multiple channel architecture (MCA) network supporting 802.1X authentication, what
aspects of WLAN design affect client roaming efficiency and effectiveness? (Choose 3)

• A.The infrastructure's roaming algorithm
• B.Key caching protocols
• C.Supported uplink and downlink MCS rates
• D.Channels supported by infrastructure
• E.Cipher suite
• F.PHY standard used by client
• G.Channels supported and scanned by client

You deployed an AP and installed its antenna, and you now need to set the AP transmit power. Given a desired EIRP of 21 dBm, and an antenna gain of 5.85 dBd connected
through 25 feet of cable with a loss specification of 4 dB/100 feet. Assuming that there is no significant loss from the connectors, what should be the transmit power level for this AP?

• A.50 mW
• B.40 mW
• C.10 mW
• D.20 mW
• E.25 mW
• F.14 mW

As an implementation engineer, you have just received initial design specs from a network designer for your dual-band 802.11n deployment. The network design documents prescribe the following data rate configuration for the 2.4 GHz radio:
Basic Rates - 5.5, 6, 11, 12 Mbps
Supported Rates -9, 18, 24, 36, 48, and 54 Mbps as well as MCS 0-15
What will result from this design strategy?

• A.This configuration violates the IEEE specification that defines 6, 12, and 24 Mbps as mandatory data rates for 802.11g/n.
• B.Protection mechanisms will always be in use on this network to support 5.5 and 11 Mbps as basic rates.
• C.HR/DSSS (802.11b) stations will not be able to associate to the service set.
• D.MCS 0 will represent the lowest data rate that can be used in the service set.
• E.By disabling support for 1 and 2 Mbps while allowing 5.5 and 11 Mbps, the network will force 802.11b clients to use these higher data rates.

Given: For this fill-in the blank question, each answer option contains an answer for the first and second blanks, separated by a dash "-". Choose the answer option that correctly fills
in both blanks in the following sentence.
A WLAN may use 802.11 admission control to ________, and admission control requirements are configured separately for each ________.

• A.Mark ingress and egress frames with priority values - TCP/IP port
• B.Administer VoWiFi use policy - VLAN
• C.Regulate the available bandwidth resources - Access Category
• D.Identify voice-enabled wireless devices - AP radio (that is, 2.4 GHz or 5 GHz)
• E.Block stations with inadequate security parameters - SSID

Given: In a site survey deliverable report, you are expected to explain the spectrum measurements taken at the customer's site. The exhibit shows a representative sample capture of the RF environment at one of the customer sites.

What best explains the data presented in this exhibit?

• A.Channel 1 is being heavily utilized by Wi-Fi and channel 11 also has some moderate Wi-Fi activity.
• B.Although some access points are present in a nearby area, they are not being heavily used.
• C.The Real Time FFT chart shows a high noise floor across the entire 2.4 GHz band.
• D.As indicated by the data in the Active Devices list, the spectrum analysis chipset is also reporting 802.11 information.
