A. SFTP
B. TLS
C. RADIUS
D. NTP
正解：C

質問 2：
A museum wants to offer Wi-Fi to its visitors. One of their requirements is to have the APs blend into the design of the museum. What should you do to meet this requirement?
A. Lock the AP inside of a metal box
B. Place the APs in between walls and I-beams
C. Use an 802.11b AP, so it looks old enough to be in a museum
D. Use a plastic cover that could blend in with the environment
正解：D

質問 3：
Your customer's 802.11n laptops are not able to see the SSID in the 5 GHz band in the conference room.
When doing a walkthrough using one of these laptops, you confirm that it is unable to see the SSID in the 5 GHz band in the conference room. When using your own 802.11 ac laptop, you're able to see the SSID. What is the most likely cause of this problem?
A. The AP is configured to use channel 36
B. The customer laptop does not support Transmit Beamforming
C. Their laptops are SISO clients
D. The AP is on channel 144
正解：B

質問 4：
You have performed a validation site survey after deploying a WLAN infrastructure that is an All-Wireless-Office. One specific application of your customer is experiencing delay when using the application after moving from wired connectivity. After your validation, you realized that all APs are using 80 MHz channel-widths instead of 20 MHz on the 5 GHz band, as it was designed. What can be done to resolve the delay on this application?
A. APs should be using 160 MHz channel-widths to get more throughput
B. Reconfigure to use 20 MHz channel-widths, so reuse of the frequency is more effective
C. Add more APs using 80 MHz channel-widths
D. Power-off half of the APs to reduce CCI and keep 80 MHz channel-widths
正解：B

質問 5：
Using a SCA means that all APs will be using the same channel in a given layer. How is the AP with which the client associates determined?
A. All APs share a virtual BSSID. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
B. All APs share a virtual IP address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
C. The client selects the AP based on a known set of MAC to BSSID mappings stored in the clients authorized SSID listing.
D. All APs share a virtual Multicast Address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
正解：C

質問 6：
What is the best method of gathering attenuation measurements from any building materials or objects?
A. After measuring the RSSI in free space 5 meters (16.5 feet) apart, put an AP 4 meters (13 feet) away from the wall or object on one side and your measuring device 0.67 meters (2 feet) away from the wall or object on the other side. Take measurement and compare the difference.
B. Use the pre-built attenuation values in the predictive design tool.
C. Look on the Internet for attenuation values for each one of the materials that might attenuate the Wi-Fi signal using the material provider's websites.
D. After measuring the RSSI in free space 1 meter (3 feet) apart, put an AP 0.32 meters (1 feet) away from the wall or object on the other side. Take measurements and compare the difference.
正解：D
