Q1 Single choice Flag Which statement about designing a migration approach of an existing Data Center network to Cisco ACI is true? A 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. B When migration is complete, the existing Layer 3 devices should still serve as the default gateway. C 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. D Simplify the migration by associating every EPG to a VLAN. Correct answer
