A business traveler from North America is in Europe. The hotel only provides coverage in 2.4 GHz. The traveler connects to the hotel's SSID and notices an AP in the hotel room. However, the laptop reports a very low RSSI when connected. The traveler does not have the same problem when connecting in the lobby. What would be the most likely cause of the low RSSI in the hotel room?
A. The AP in the room is using ZigBee instead of Wi-Fi.
B. The AP in the room is transmitting on channel 13 and the traveler associated to a non-channel 13 AP located elsewhere.
C. The switchport that the AP is connected to is only capable of transmitting at 10 Mbps.
D. The AP in the room is using Bluetooth instead of Wi-Fi.
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
You and 10 other people are connected to a public hotspot. You issue a ping sweep on the network, but you can't find any devices on the same subnet as yours. What feature might be enabled on the WLAN infrastructure that is preventing you from communicating with other devices on that subnet?
A. Peer-to-peer blocking
B. OSPF external routes
C. Band steering
D. Load balancing
Your customer requires fast secure roaming. Which two types of roaming are specified in 802.11-2016 FT roaming that will help meet this goal?
A. Over-the-Air and Over-the-DS
B. Over-the-Air and Over-the-Wire
C. FT and OKC
D. FT and TKIP
When deploying a new WLAN infrastructure using PoE to power the APs, you realize that a known good AP is not powering up. You use the same cable to connect your laptop and connect without any trouble. What is the most likely reason the AP did not power up?
A. Missing AP licenses in the controller
B. Spanning-tree convergence
C. Layer 3 routing
D. Lack of PoE budget on the switch
During your first pre-deployment meeting with the deployment team, you hand out the full design documentation to all of them. What's your primary goal during this meeting?
A. To explain design decisions and ensure understanding of design documents.
B. To discuss AP functionality.
C. To explain how Wi-Fi works.
D. To justify the budget.
What kind of site survey helps you identify if roaming is working as designed?
A. Passive
B. Predictive
C. Active
D. Spectrum analysis walkthrough
You are validating association capabilities from clients to an 802.1X/EAP secure SSID. The RADIUS server's IP address is 10.100.50.25 and the default RADIUS authentication port is used. When testing them, none of the clients are able to associate to the SSID. Troubleshooting the WLAN infrastructure, you found out that the server is up and the RADIUS service is up as well, but the authenticator is not able to communicate properly with the server. What's your next troubleshooting step?
A. Verify that the shared secret between the authenticator and the RADIUS server is correct
B. Reboot the clients
C. Reboot the server
D. Restart the RADIUS service
During lunch time in the break room of a company, Wi-Fi connectivity on the 2.4 GHz band is intermittent. Every other time of the day, it works fine. What's the likely cause of this issue?
A. Employees are using their cell data instead of using the Wi-Fi
B. The AP in the cafeteria keeps rebooting due to lack of PoE budget on the switch
C. Toasters and ovens are heating up the air, raising the noise floor with the Wi-Fi on the 2.4 Ghz band
D. Microwaves in the cafeteria are interfering with the Wi-Fi on the 2.4 GHz band
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. Power-off half of the APs to reduce CCI and keep 80 MHz channel-widths
D. Add more APs using 80 MHz channel-widths
