You have a customer that is building a new campus of four 3-story buildings that you have just completed the site survey for. The customer is interested in the mount of rack space they will need to allocate in either the building MDF or in the data center for controllers. Each building is going to require 75 APs to support voice and data. How should the controllers be deployed to provide the least number of controllers, the highest redundancy, and the easiest management?
A. Use the centralized deployment method in the data center with the N + N redundancy method.
B. Use the centralized deployment method in the data center with the N + 1 redundancy method
C. Use the centralized deployment method in the data center with the 1 + 1 redundancy method and client SSO.
D. Use the distributed deployment method in each building MDF with the N + 1 redundancy method.
E. Use the distributed deployment method in each building MDF with the N + N + 1 redundancy method.
F. Use the distributed deployment method in each building MDF with the N + N redundancy method.
C
I think it is c
The WLC in the Standby state does not need to be configured independently as the entire configuration (Bulk Configuration while boot up and Incremental Configuration in runtime) will be synced from the Active WLC to the Standby WLC via a Redundant Port. The AP’s CAPWAP State (only APs which are in a run state) is also synced, and a mirror copy of the AP database is maintained on the Standby WLC. The APs do not go into the Discovery state when the Active WLC fails and the Standby WLC takes over the network’s Active WLC.

B) Correct !!!
SSO and N+1 are two different implementations ! In both separately you need X2 WLCs!
In both as combination you need X3 WLCs Min. !!!
So does that mean that C is the correct answer
but what i believe , answer B is correct , because if you go back to CCNA wireless book , 1+1 means both are active and doesn’t mean 1 active and 1 standby
ohh
but i remember now in the exam it was clearly written 1:1 and not 1+1
Nayef,
Can you please tell if there was any new question…. other than those 140 from passlead
this question came in the exam as i attended it today 9-4-2018 , i failed the exam , i answered C , but no one can tell if the answer was correct or not , i scored 802 and passing score is 832
Hi
I share the thought of Eric. In my opinnion, the correct answer is C
which is the correct answer? i take exam in the morning…did you see the cable question and also the what rf is measured in ..db or dbm? please help!
It looks like the correct answer is “C”.
From Cisco.com
“The new architecture for HA is for box-to-box redundancy. In other words, 1:1 where one WLC will be in an Active state and the second WLC will be in a Hot Standby state continuously monitoring the health of the Active WLC via a Redundant Port. Both the WLCs will share the same set of configurations including the IP address of the Management interface. The WLC in the Standby state does not need to be configured independently as the entire configuration (Bulk Configuration while boot up and Incremental Configuration in runtime) will be synced from the Active WLC to the Standby WLC via a Redundant Port. The AP’s CAPWAP State (only APs which are in a run state) is also synced, and a mirror copy of the AP database is maintained on the Standby WLC. The APs do not go into the Discovery state when the Active WLC fails and the Standby WLC takes over the network’s Active WLC.”
