質問 2

You have designed a WLAN with a plan for 87 APs m a large office building. The customer has informed you that the budget is not as large as they hoped and they can only purchase 53 APs What action should be taken?

（A）Perform a complete redesign of the wireless network and inform the customer if some original requirements cannot be accomplished

（B）Use only 2.4 GHz radios because the signals can be received at a greater distance

（C）Remove as many walls as possible within the facility so that the signals can travel a g<eater distance

（D）Simply increase the output power of the APs by 30 percent to accommodate tor the smaller number of purchased APs

質問 5

You ate evaluating CO impact in 2 4 GHz. During the post-validation survey, you determine that 2 or 3 APs are seen from every location in the 2 4 GHz band with signal strengths above -75 dBm from all seen Aps.
Does this show that CO has been removed from the environment given that three non-overlapping channels exist in 2.4 GHz and why?

（A）Yes, because the goal is to see only l AP at each location in 2 4 GHz

（B）No, because the goal is to see only 1 AP at each location in 2 4 GHz

（C）No, because CCI can exist even with signals as low as -85 dBm to -93 dBm

（D）Yes because you would see 3 APs m every location with a signal strength above -75 dBm if CO exists

Response:

（A）#139 dBm

（B）#174 dBm

（C）#144 dBm

（D）#204 dBm

質問 7

An organization has chosen to implement Wi-Fi 6E and operates in a regulatory domain allowing the use of all 6 GHz channels. Why can 40 MHz channels be used more easily in this network than one operating in the
5 GHz band?

（A）Because ACI works differently in 6 GHz than in 5 GHz

（B）Because many more channels are available

（C）Because Wi-Fi 6E supports 40 MHz as a primary channel and ignores 20 MHz primary channels

（D）Because 6 GHz Wi-Fi uses Single Channel Architecture instead of Multiple Channel Architecture

質問 9

An AP vendor being considered for a WLAN deployment suggests that their 2 4 GHz and 5 GHz dual-band APs use software defined radios What unique capability does this indicate in comparison to non-software defined radios?

（B）The radios can have their SSlDs configured through software

（C）Software is used to configure the encryption settings

（D）Software is used to configure the entire WLAN profile

質問 13

You are tasked with designing the WLAN to accommodate certain high density areas on your university campus where users frequently come and go. With a limited DHCP pool size (subnet mask = 255.255.252.0) for this WLAN subnet, you want to ensure that your DHCP addresses are used efficiently and are not exhausted, which would prevent new client Layer 3 connections. The DHCP server is a Windows Server 2012 R2 machine.
Your design task is to determine the best configuration to allow as many users as possible while avoiding WLAN service interruptions and also to use the available addresses as efficiently as possible.
What setting would be most effective at achieving this design task?

（A）Set the inactive wireless client timeout (client age-out) to 5 minutes

（B）Set the RTS threshold to 2346 bytes

（C）Set the maximum client limit per radio to 64

（D）Set the DHCP lease for this pool to 20 minutes
