An engineer is designing a network deployment for a technology company. The company has four buildings with access points that must provide seamless wireless coverage and client roaming. The customer data center must have two WLCs and the core switches for the network. Which type of wireless architecture must be used?
Show answer
Answer: B

Select 2
Refer to the exhibit. A customer is deploying a Greenfield 802.11n network with data, voice, and location awareness using APs with the WSSI modules. Which two settings in the Cisco Prime Infrastructure Planning Tool, when selected, provide a more accurate prediction of the number of APs the customer must purchase for the new facility? (Choose two.)
Show answer
Answer: BE
Explanation
Voice and location only, no monitoring mode needed. The WSSI module is a specialized radio that transfers monitoring and security services from the client/data serving radios to the security monitor module. This results in improved client performance and cost reduction by eliminating the necessity for dedicated monitor mode access points

An engineer in a branch office that does not have a wired backhaul must ensure that local clients can be switched locally and authenticated centrally. In which mode must the AP be configured?
Show answer
Answer: B
Question 88 · 245 in bank
When a wireless network is designed for location services, how many APs must be heard by each location-ready AP at a signal level of -75 dBm or better?
Show answer
Answer: A
Explanation
strange question. -75dBm is the requirement for the tracking device to be head by at least three APs. Not about APs hearing each other.

A company is in the process of relocating to a new office space and finds out that the Internet circuit will not be ready before the move. The new building has a non-Cisco WLAN to which they can connect. The engineer has a 12-port switch and one Cisco autonomous AP and must connect multiple wired devices. Which additional device is needed to get all clients connected over the workgroup bridge?
Show answer
Answer: A
Question 90 · 245 in bank
An engineer is implementing a wireless design for a service provider. The design includes a Catalyst 9800, a stack of two Catalyst 9300X-48HX switches, and 9166 APs. Each AP must be named using the Floor-439412509-01X sting where X is the area number. The engineer wants to connect the APs to the switch stack using POE. How many APs must the engineer connect to the stack so the APs run using full functionalities?
Show answer
Answer: C
Explanation
The Cisco data sheet for the C9300X-48HX with a default build i.e. 1 x 1100W PSU (no 2nd PSU or an upgrade to the 1900W PSU) can provide a PoE budget of 590W. The 9166 APs require a minimum and with all radios on 802.3at (PoE+). This is with the USB port off/unpowered. This is 25.5W per AP. Or 802.3bt (UPOE) with the USB port now on (takes 4.5W). The AP running at full functionality requires 30.5W max. So this is either: Default PoE budget of 590W / 25.5W = 23 APs Or default PoE budget of 590W / 30.5W = 19 APs So the answer must be half ports per switch and that isn't really possible except the resting power draw may be a little less.
