Q187. Which of the following two statements about Cisco NSF and SSO are the most relevant to the network designer? (Choose two.) 

A. You can reduce outages to 1 to 3 seconds by using SSO in a Layer 2 environment or Cisco NSF with SSO in a Layer 3 environment. 

B. SSO and NSF each require the devices to either be graceful restart-capable or graceful restart-aware. 

C. In a fully redundant topology adding redundant supervisors with NSF and SSO may cause longer convergence times than single supervisors with tuned IGP timers
