Q21. 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. Block stations with inadequate security parameters — SSID
B. Identify voice-enabled wireless devices — AP radio (that is, 2.4 GHz or 5 GHz)
C. Regulate the available bandwidth resources — Access Category
D. Mark ingress and egress frames with priority values — TCP/IP port
Q22. What VoWiFi implementations frequently require multicast packet delivery support by the WLAN infrastructure?
A. All VoWiFi implementations
B. Push-to-Talk VoWiFi phones
C. All VoWiFi soft phones
D. All VoWiFi hard phones
Q23. You are selecting external antennas for use in a bridge link deployment. What chart should you request from the antenna vendors to make an accurate selection?
A. mW to dBm conversion chart
B. dBm to dB conversion chart
C. Elevation chart
D. Antenna coating chart
Q24. In a PC-based spectrum analyzer, what data chart identifies the overall RF utilization of a specific frequency in the environment being surveyed?
A. FFT Max Hold
B. FFT Average
C. Swept Spectrogram
D. Duty cycle
Q25. Why does a frame transmitted at 1 Mbps have a greater usable range than the same frame transmitted at 54 Mbps?
A. Free space path loss causes greater signal dispersion for higher rate transmissions.
B. Receiver sensitivity requirements are lower for frames transmitted with less complex modulation and coding.
C. To improve reliability, 802.11 STAs increase transmit power as the signaling rate decreases.
D. Lower data rate RF transmissions travel at higher speeds and are less likely to experience collisions.

Q26. As you plan a WLAN upgrade, you have assessed the network requirements and data signatures of your applications. One of the popular applications used on your network requires high bandwidth and low to medium Wi-Fi loss, but can tolerate moderate latency and jitter.
What application matches this description?
C. Skype chat
Q27. 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. 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.
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. This configuration violates the IEEE specification that defines 6, 12, and 24 Mbps as mandatory data rates for 802.11g/n.
Q28. One of your customers plans on providing wireless coverage to a warehouse facility. After performing an initial walkthrough, you collect the following information:
. The central part of the warehouse is between 400 and 600 feet (122 to 183 meters) from the warehouseswitches mounted on the walls. . The warehouse storage is composed of metallic racks with varying inventory levels and contents, from electronics and plastic toys to food pallets and juice bottles. . Workers need basic data coverage from their working location, and are not highly mobile. They usually work from one single aisle, and their laptop is on a cart with
What would be your one recommendation to provide coverage to the central area of the warehouse?
A. Equip workers laptops with a directional antenna and install APs less than 328 feet (100m) away from the switch.
B. In this case, extend the cable length just beyond 328 feet (100 m) and position APs as close as possible to the central area of the warehouse.
C. Position APs along the walls, and equip the APs with Yagi antennas to cover the central area.
D. Install APs for client access in the central area and use a mesh backhaul link to connect to the DS.
Q29. When deploying long-distance 802.11 bridge links (10 miles / 16 km), what parameter may be critical for improving data flow by reducing retries caused by the long distances?
A. The sequence control field value
B. The acknowledgement timeout threshold
C. The minimum transmit data rate value
D. The CTS-to-self threshold
Q30. When you see the SKINNY protocol in a post-install validation protocol capture, what does this indicate?
A. Secure FTP is in use
B. VoIP is used on the network
C. HTTPS is in use
D. Multicasting is used on the network
