An engineer is trying to determine the most cost-effective way to deploy high availability for a campus enterprise wireless network that currently leverages three wireless LAN controllers. Which architecture should the engineer deploy?
A. N+N with SSO
B. N+1 solution without SSO
C. N+N solution without SSO
D. N+1 with SSO
B – N+1 HA —- > SSO is not supported
If leveraging 3 controllers, N+1 with SSO where “N” is the SSO pair and the “+1” is the 3rd controller?
Answer: B
B – “The N+1 HA architecture provides redundancy for controllers across geographically separate data centers with low cost of deployment.”
Not D – “Access Point Stateful Switch Over (AP SSO) functionality is not supported for N+1 HA.”
