An engineering firm just upgraded their WLAN form nine 802.11n APS to nine 802.11ac APs. After this upgrade, they did not see any improvement in throughput.
What is the most likely cause of this result?
- A . APs are transmitting at a low transmit power
- B . The clients were not upgraded
- C . APs are mounted on the wall
- D . The APs are still using the 5 GHz lower band
B
13 1. You and 10 other people are connected to a public hot-spot. 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?
Given: The 802.11ac APs you have selected for your public access deployment support many of the PHY and MAC enhancements offered by the 802.11n and 802.11ac amendments. The AP is configured for a single-band (2.4 GHz) and only allows 20 MHz channels. The WLAN radio in the AP is a 3×3 802.11n chip that supports two spatial streams.
What is the maximum MCS rate that could be supported by this AP?
- A . 54 Mbps
- B . 65 Mbps
- C . 108 Mbps
- D . 144 Mbps
To ensure that your design meets the requirements of the WLAN, what should be defined in your WLAN design software that will result in different requirements at varying locations on the floor plan1?
- A . Requirement areas
- B . Cable runs
- C . Heatmap colors
- D . Project name
What commonly causes a client-to-AP link imbalance?
- A . The client’s antenna gain is lower than the AP’s antenna gain
- B . The client’s transmit power is significantly lower than the AP’s transmit power
- C . The AP’s transmit power is significantly lower than the client’s transmit power
- D . The AP’s antenna gain is lower than the client’s antenna gain
You are being asked to design a WLAN for a number of WLAN clients that will use Telnet as the primary application. The customer has asked that you use only the number of APs necessary because of the complex installation and construction costs each AP installation will incur in this particular environment.
What design factors do you consider?
- A . Omnidirectional antennas should be used to maximize cell overlap.
- B . Use 11 Mbps as the lowest basic rate.
- C . Clients could benefit from RTS/CTS mode for all transmissions.
- D . AP transmit power should be turned down to minimize co-channel interference.
What might limit the ability to locate 802.11 clients using a WLAN infrastructure without an 802.11 tag? (Choose all that apply.)
- A . Lack of 802.11k support
- B . When its radio is disabled
- C . When it is off
- D . RF channel selection
What is the primary reason for avoiding 160 MHz channels with 802 11 in the 5 GHz band’?
- A . Only two oi three 160 MHz channels exist in the current frequency allocation, tn some regulatory domains only one exists
- B . The data rate becomes too high which causes some clients to gam access to the medium and never let it go
- C . The output power requited for 160 MHz channels is more than most regulatory domains allow
- D . No APs exist in production that can implement 160 MHz channels
After designing and deploying a WLAN infrastructure, you realized the CCI is causing poor performance in the 2.4 GHz band. Primarily, you’ve designed the WLAN for 5 GHz and 2.4 GHz as a best effort. You found out that the implementers didn’t follow your guidelines when configuring the WLAN infrastructure.
What can you do to minimize as much as possible the CCI impact in the 2.4 GHz band?
- A . Add more APs to the infrastructure
- B . Increase the transmit power on all APs
- C . Turn-off 2.4 GHz radios on some APs
- D . Use all channels available in the 2.4 GHz band
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
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
