Which statement about designing a migration approach of an existing Data Center network
to Cisco ACI is true?
A.
When migration is complete, the existing Layer 3 devices should still serve as the default
gateway.
B.
The service nodes must be moved first because Layer 4 to Layer 7 services (FW/LB) in
the existing network will not be functional during migration.
C.
The first action is to connect the Cisco APIC to the existing core Layer 3 routers so that
the APIC can begin to be involved in traffic forwarding.
D.
Simplify the migration by associating every EPG to a VLAN.
