Which option is for migrating an existing Data Center network to Cisco ACI?
A.
First migrate existing FEXs to 9500.
B.
First connect the core (for example, Cisco ASR 9000 Router or Cisco Nexus 7000 Series
Switches) to the ACI fabric that supports external connectivity routing mechanisms (OSPF
NSSA, iBGP, and static routes).
C.
First disable flooding on each bridge domain during migration to avoid broadcast storms.
D.
First migrate existing access layer (for example, Catalyst 5500/6000 + FEX) to Cisco
MDS 9500 Series.
