What security solution is deprecated in the 802.11 standard and should never be used in any modern WLAN deployment?
- A . AES
- B . Shared Key Authentication
- C . CCMP
- D . Open System Authentication
You are reconfiguring an AP to use the short guard interval.
How long will the new guard interval duration be after the change?
- A . 400 ns
- B . 10 ms
- C . 800 ns
- D . 104 ms
What statement about the IEEE 802.11-2016 QoS facility is true?
- A . 802.11 QoS is achieved by giving high priority queues a statistical advantage at winning contention.
- B . Four 802.1p user priorities are mapped to eight 802.11 transmit queues.
- C . 802.11 control frames are assigned to the 802.11 EF priority queue.
- D . When the Voice queue has frames awaiting transmission, no data will be transmitted from the Best Effort queue.
You manage a WLAN with 100 802.11ac access points. All access points are configured to use 80 MHz channels. In a particular BSS, only 40 MHz communications are seen.
What is the likely cause of this behavior?
- A . The short guard interval is also enabled.
- B . The clients are all 802.11n STAs or lower
- C . The AP is improperly configured to use only 40 MHz of the 80 MHz allocated bandwidth
- D . All clients implement single spatial stream radios
When compared with legacy Power Save mode, how does VHT TXOP power save improve battery life for devices on a WLAN?
- A . VHT TXOP power save allows stations to enter sleep mode and legacy Power Save does not.
- B . VHT TXOP power save allows the WLAN transceiver to disable more components when in a low power state.
- C . VHT TXOP power save uses the partial AID in the preamble to allow clients to identify frames targeted for them.
- D . Legacy Power Save mode was removed in the 802.11ac amendment.
What 802.11 network configuration would result in multiple stations broadcasting Beacon frames with the same BSSID but with different source addresses?
- A . A single AP supports multiple BSSs with different SSIDs.
- B . An SCA network is in use.
- C . Multiple APs have been loaded with the same configuration from an image file.
- D . An IBSS is used instead of a BSS.
What primary metric of scanning can stations use to select the best AP for connectivity to the desired BSS?
- A . Signal strength of AP beacons received.
- B . PING latency when testing against an Internet server.
- C . FCS errors in frames transmitted to and from the AP.
- D . Throughput speed in Mbps.
Lynne runs a small hotel, and as a value added for his customers he has implemented a Wi-Fi hotspot. Lynne has read news articles about how hackers wait at hotspots trying to take advantage of unsuspecting users. He wants to avoid this problem at his hotel.
What is an efficient and practical step that Lynne can take to decrease the likelihood of active attacks on his customers’ wireless computers?
- A . Implement Network Access Control (NAC) and require antivirus and firewall software along with OS patches.
- B . Implement an SSL VPN in the WLAN controller that initiates after HTTPS login.
- C . Enable station-to-station traffic blocking by the access points in the hotel.
- D . Require EAP_FAST authentication and provide customers with a username/password on their receipt.
You have been tasked with creating a wireless link between two buildings on a single campus. The link must support at least 150 Mbps data rates.
What kind of WLAN technology role should you deploy?
- A . IBSS
- B . WPAN
- C . Access BSS
- D . Wireless bridging
When implementing PoE, what role is played by a switch?
- A . PD
- B . PSE
- C . Midspan injector
- D . Power splitter
