Which steps must be taken when migrating from a cascaded topology to a core-edge
topology? (Select two)

A.
Calculate the number of ports needed for the additional ISLs

B.
Remove the cross-connected ISLs and leave the outer-connected ISLs

C.
Connect required servers, storage devices, and core switches

D.
Re-cable the ISLs to connect all edge switches to the core switches

E.
Connect high-performance servers to both a core switch and an edge switch

Explanation:
Cascaded to core-edge
Determine which switches will be the backbone switches and which ones will be the edge
switches.
Re-cable the ISLs to connect all edge switches to the core switches. Connect devices
(servers and storage) or core switches, as required. This migration is less disruptive if you
use the existing switches as edge switches and add switches as core switches.
