• Question 683:

  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
  D. The primary deployment scenario for Cisco NSF with SSO is in the Distribution and Core layers.
  E. Cisco NSF-aware neighbor relationships are independent of any tuned IGP timers
  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

  switchover (SSO) may cause longer convergence times than single supervisors with tuned IGP timers."

  "A graceful restart-aware neighbor is required so that graceful restart -capable systems can rebuild their databases and maintain their neighbor adjacencies across a switchover."

  C. Host A can always reach host B through S1
  D. The redundant links between the switches are blocked
  D. The redundant links between the switches are blocked
