It's C and E
C, E 3
Selected Answer: CE
In a Cisco Nexus 9000Series chassis with dualsupervisors, you can use the in-service software upgrade (ISSU)
feature to upgrade the system software while the system continues to forward traffic. An ISSU uses the existing
features of nonstop forwarding (NSF) with stateful switchover (SSO) to carry out the software upgrade with
no system downtime.
