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 clientSSO.
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.
It is not a very good question. In this case, 4 buildings, each needs 75 APs, in total only 280 APs are needed. 1 WLC is enough to support 75 APs, so centralized deployment is the first part of the answer.
N+1 has lowest redundancy, the least number of controllers, the easiest management
N+N has the high redundancy, not the least number of controllers, not the easiest management
N+N+1 has the highest redundancy, not the least number of controllers
No answer meets all 3 requirements, N+1 meets 2 requirements, N+N and N+N+1 each only meets 1 requirement, so N+1 seems to be the best answer in all answers… so A
Answer is C. 1+1 means a backup for every primary (high redundancy), centralized deployment (least number of controllers and easiest management), client SSO (high redundancy).
Highest Redundancy is the key point, N+1 allows the most amount of licenses and failover from multiple WLCs
No such thing like C)
B) Correct!!!
There is a 1+1 redundancy method using AP-SSO. Using AP-SSO gives the AP the highest redundancy, as the APs almost does not feel any timeout from the primary to the secondary WLC upon re-association since both WLCs act as one WLC.
Easiest management, least number of controller deployed and high availability.
C is the best answer.
