Select all that apply.

• 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
