Implementing Cisco Application Centric Infrastructure (DCACI) — Question 39
An engineer is implementing Cisco ACI at a large platform-as-a-service provider using APIC controllers, 9396PX leaf switches, and 9336PQ spine switches. The leaf switch ports are configured as IEEE 802.1p ports. Where does the traffic exit from the EPG in IEEE 802.1p mode in this configuration?
Answer options
- A. from leaf ports tagged as VLAN 0
- B. from leaf ports untagged
- C. from leaf ports tagged as VLAN 4094
- D. from leaf ports tagged as VLAN 1
Correct answer: A
Explanation
The correct answer is A because, in IEEE 802.1p mode, traffic exits from leaf ports that are tagged as VLAN 0, which denotes untagged traffic in this context. Options B, C, and D are incorrect because untagged traffic is not correctly represented in B, and VLAN 4094 and VLAN 1 do not apply for traffic exiting the EPG in this configuration.
