Which of these statements is correct regarding Stateful Switchover and Cisco Nonstop
Forwarding?
A.
Utilizing Cisco NSF in Layer 2 environments can reduce outages to one to three seconds.
B.
Utilizing SSO in Layer 3 environments can reduce outages to one to three seconds.
C.
Distribution switches are single points of failure causing outages for the end devices.
D.
Utilizing Cisco NSF and SSO in a Layer 2 environment can reduce outages to less than one
second.
E.
NSF and SSO with redundant supervisors have the most impact on outages at the access
layer.
E
Cisco NSF with SSO and redundant supervisors has the most impact in the campus in the
access layer. An access switch failure is a single point of failure that causes outage for the end devices connected to it. You can reduce the outage to one to three seconds in this access layer, as shown in Figure 2-8, by using SSO in a Layer 2 environment or Cisco NSF with SSO in a Layer 3 environment.
