Exam 300-425 topic 1 question 34 discussion

looking at the “42” number, but indeed since it mentions computer + VoIP =84 It’s 5. Workgroup bridges support 20 cliens maximum.

up to 20 wired clients are supported behind of cisco WGB

VoIP & Computer together need only 1 port

Minimum is the key to this answer

The answer should be B. This is from the deployment guide.. A Cisco WGB provides information about its wired clients via Internet Access Point Protocol (IAPP) messaging. This enables the wireless infrastructure to know the MAC addresses of the WGB’s wired clients. Up to 20 wired clients are supported behind a Cisco WGB. https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-1/configuration-guide/b_cg81/workgroup_bridges.pdf Since each user will consume 2 clients (PC/IP Phone) and we have 48 Users we will need minimum of 5x AP's to support 84 Clients

According to Cisco ENWLSD Course, it is B. WGBs support up to 20 clients.

a WGB is used to provide access to the network through wireless to a device that doesn't have wireless capability, so if they want to use APs on WGB mode, we could assume that the laptops and VoIP phones are not wifi capable, so they will use the ethernet port of the AP to connect to the network. An AP on WGB mode can support up to 20 wired clients, so if there are 42 clients with two devices each, the total amount of devices to be connected to the WGBs will be 84 and we need at least 5 APs on WGB mode to support all those clients: https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-5/config-guide/b_cg85/workgroup_bridges.html#wgb

Tricky Question. A general rule-of-thumb is ~20-30 users per AP. https://community.cisco.com/t5/wireless/how-to-limit-maximum-wireless-client-count-per-ap/td-p/2419273 Also look at the book, Chapter 5 page 101 "This time if the room is full of people, each AP might carry around 25 associated clients" The question says "must be ordered to keep cost at minumum while connecting all devices" I will go with answer A

https://community.cisco.com/t5/wireless-mobility-documents/how-many-clients-can-be-connected-to-an-access-point/ta-p/3115019 Number of 802.11b devices per AP: Cisco recommends that you have no more than 15 to 25. 4*25=100 42*2=84 Answer A

Answer B - 5 WGBs 42 x 2 = 84 Clients

Answer: A
