Which two describe the correct requirements for non-disruptive IOS ISSU on Cisco Nexus 7000 Series Switches? (Choose two.)
A. updated kickstart and system images must be staged in bootflash on single-supervisor switches
B. updated kickstart and system images must be staged in bootflash on dual-supervisor switches
C. low version skew
D. dual supervisors
E. clock synchronization
This is definitely wrong, but I would argue that it should be B and D. The question specifies a Nexus 7000, and dual sups are a requirement for an ISSU on a 7K. That said, A can’t be right, since it is for a single supervisor.
Shouldnt it be BC?
