What is the reason the upgrade would not be hit-less for the entire switch, above?
A. The supervisor module requires a BIOS upgrade, which is disruptive.
B. The "rolling-upgrade" for module 2 requires a second "slc" to be hit-less.
C. Module 3 is an IPS-8 card, which does not support non-disruptive downgrades.
D. Nodule 3 is an IPS-8 and the switch does not have a second IPS-8 card for route diversity which could provide a "stable" upgrade.
E. No reason - the upgrade is non-disruptive and hit-less.
