Exam 200-155 | Question id=4588 | Application Centric Infrastructure |
Refer to the exhibit.
Which statement accurately describes how traffic is handled within the fabric?
A. |
Traffic with the source and the destination on the same leaf switch is managed locally, and all other traffic is managed by the master spine switch that is orchestrated by the Cisco APIC host. | |
B. |
All traffic is managed by the master spine switch that is orchestrated by the Cisco APIC host. | |
C. |
Traffic with the source and the destination on the same leaf switch is managed locally, and all other traffic travels from the ingress leaf to the egress leaf through a spine switch. | |
D. |
All traffic is managed by the master leaf switch that is orchestrated by the Cisco APIC host. |
The ACI fabric provides consistent low-latency forwarding across high-bandwidth links (40 Gbps, with a 100-Gbps future capability). Traffic with the source and destination on the same leaf switch is handled locally, and all other traffic travels from the ingress leaf to the egress leaf through a spine switch. Althought his architecture appears as two hops from a physical perspective, it is actuallya single Layer 3 hop because the fabric operatesas a single Layer 3 switch.
