In high-density environments, such as stadiums and convention centers, what extra factor has to be taken into account that can attenuate Wi-Fi signals when these environments are having an event?
A. Thick walls
B. I-Beams
C. People
D. Fire doors
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
During an RFP analysis, one of the vendors mentioned that you'll need to upgrade your Gigabit Ethernet switches to MultiGig switches to ensure support for 802.11ac and 802.11ax, which both offer data rates over 1Gbps. Why is this not sound advice?
A. Because neither of the technologies support data rates over 1Gbps
B. Because 802.11ax doesn't support channel bonding
C. Management overhead that is normal in WLANs will reduce the throughput of the client devices
D. Because 802.11ac only supports one spatial stream
You performed a site survey with two USB Wi-Fi adapters using a special driver written for the site survey software. After deployment, you realized that the client devices used by your customer are getting lower RSSI values than that shown during your site survey. What is the most likely reason for this result?
A. USB Wi-Fi adapters designed for site surveys may have better sensitivity than regular Wi-Fi cards installed in client devices.
B. The transmit power on the APs is higher than needed.
C. Regular Wi-Fi cards installed in client devices do not support the same protocols as survey adapters.
D. USB Wi-Fi adapters have a greater sensitivity than internal Wi-Fi adapters.
What advantage provided by 802.11n and 802.11ac is not usable in 1X1:1 low-end client devices?
A. Channel bonding
B. MCS data rates
C. Maximal Ratio Combining
D. Mandatory data rates
When deploying APs outdoors, what additional component needs to be used that is not needed indoors?
A. Antennas
B. NEMA enclosures
C. Ethernet cables
D. PoE
What service must be implemented on your customers' network to authenticate users against an LDAP database prior to access to the WLAN infrastructure being granted?
A. NTP
B. RADIUS
C. SFTP
D. TLS
What document should be created that provides instructions for install technicians to mount and configure APs?
A. Hold Harmless
B. Statement of Work
C. Bill of Materials
D. Physical installation guide
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
What are the deliverables to your customer after successfully implementing a WLAN infrastructure?
A. Digital or physical assets, guides, floorplans and configuration documents
B. Project Charter
C. Facility blueprints
D. Nothing is required. The implemented WLAN was deliverable
