Install technicians are deploying a multi-floor WLAN that you have designed They have finished the first floor and all APs on that floor are powered on and functioning No APs on any other floors have been deployed at this time You are considering performing a post-deployment site survey of the first floor immediately to validate proper implementation What statement is true about this site survey if you perform it?

A. It will result in a complete set of data informing you how clients will function after the entire WLAN is implemented

B. It will show you how the first floor will function after all other floors are deployed

C. It will miss any impact on the WLAN caused by APs on other floors

D. It will not work because the controllers cannot function properly until all APs licensed lo the controller are operational

出題：4

When selecting a centralized WLAN architecture, what new problem may arise when you change the data forwarding model from centralized to distributed?

A. The router between the APs and the controller must be made aware of the APs as forwarding client STAs.

B. All RRM controls will also need to be distributed to a master AP that acts as a channel and transmit power arbiter for other APs in the ESS.

C. Centralized control functions, such as key management and distribution, RRM, and load balancing will no longer be supported.

D. APs that were designed for a centralized forwarding model may not support all features in distributed forwarding mode.

出題：8

When creating a long-distance bridge link, it is important to know the channels in use by other networks on both ends of the link and within a reasonable range It is not as Important to know the channels in use in the middle area of the link. Why is this the case?

A. Your RF LoS will always be far above any interference in the middle because the signal travels up and then back down to the remote 802.11 receiver

B. The signals in the middle of the link will increase the amplitude of your signal as it passes through them

C. interference happens at the transmitter

D. Interference happens at the receiver

出題：13

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. Power-off half of the APs to reduce CCI and keep 80 MHz channel-widths

B. APs should be using 160 MHz channel-widths to get more throughput

C. Reconfigure to use 20 MHz channel-widths, so reuse of the frequency is more effective

D. Add more APs using 80 MHz channel-widths

出題：14

Given: In a site survey deliverable report, you are expected to explain the spectrum measurements taken at the customers site. What portion of a spectrum analyzer view can be used to determine if a given channel is too active for use as the active channel for a new AP?

B. Duty cycle

C. Device list

D. Frame decode
