The Cisco UCS administrator has the chassis discovery policy set to “2-link”. The administrator
connects a new chassis to the Cisco UCS 6200 Series Fabric Interconnects using four links.
Which option about link utilization is true?
A.
The Cisco UCS will use two links until the chassis is reacknowledged, after which it will use all
four links.
B.
The Cisco UCS will use all four links for discovery.
C.
The Cisco UCS will use only two links. The other two links are unusable.
D.
The Cisco UCS will use only two links. However, the administrator can manually pin traffic to
the extra links by using service profiles.
This another question around chassis /fex discovery processes if you add a chassis with more links than the set amount in the discovery policy after initial discovery, you must reacknowledge the chassis that are wired for a greater number of links
and Cisco UCS Manager configures the chassis to use all available links.
