300-630 Exam Dumps : Implementing Cisco Application Centric Infrastructure - Advanced (DCACIA)

 In Cisco ACI, shared services like firewalls should be configured in the common tenant. This allows all tenants to access the services without duplicating them in each tenant.

 In a Cisco ACI Multi-Pod environment that is expanding, spine headend replication should be configured to ensure efficient forwarding of BUM (Broadcast, Unknown unicast, Multicast) traffic across the IPN (Inter-Pod Network). This configuration optimizes the control plane scaling and ensures that BUM traffic is handled effectively, maintaining network performance and stability.
