1. Question 1

   In a Cisco ACI Multi-Site fabric, the Inter-Site BUM Traffic Allow option is enabled in a specific stretched bridge domain. What is used to forward BUM traffic to all endpoints in the same broadcast domain?

   Aingress replication on the spines in the source site
   

   Begress replication on the source leaf switches
   

   Cegress replication on the destination leaf switches
   

   Dingress replication on the spines in the destination site
   

   Correct answer: A

   In a Cisco ACI Multi-Site fabric, when the Inter-Site BUM Traffic Allow option is enabled in a specific stretched bridge domain, ingress replication on the spines in the source site is used to forward Broadcast, Unknown unicast, and Multicast (BUM) traffic to all endpoints in the same broadcast domain.This method ensures that BUM traffic is efficiently replicated across the fabric, reaching all relevant endpoints without overwhelming the network with unnecessary traffic4.

   
   

2. Question 2

   Refer to the exhibit.

   

   Between Cisco UCS Fls and Cisco ACI leaf switches, CDP is disabled, the LLDP is enabled, and LACP is in Active mode. Which two discovery protocols and load-balancing mechanism combinations can be implemented for the DVS? (Choose two.)

   ACDP enabled, LLDP disabled, and LACP Active
   

   BCDP disabled, LLDP enabled, and MAC Pinning
   

   CCDP enabled, LLDP disabled, and MAC Pinning
   

   DCDP enabled, LLDP enabled, and LACP Active
   

   ECDP enabled, LLDP disabled, and LACP Passive
   

   FCDP disabled, LLDP enabled, and LACP Passive
   

   Correct answer: B, F

   In the given scenario where CDP is disabled, LLDP is enabled, and LACP is in Active mode between Cisco UCS FIs and Cisco ACI leaf switches for the DVS setup, the compatible discovery protocol would be LLDP since it's already enabled. As for load-balancing mechanisms with this setup: MAC Pinning can be used without relying on any link discovery protocol like CDP or LACP; hence option B is valid. Option F suggests using LACP in Passive mode, which could complement the existing Active mode on other devices to establish an LACP negotiation successfully.Reference: = Implementing Cisco Application Centric Infrastructure Official Cert Guide

   
   

3. Question 3

   An engineer must implement a full mesh Cisco ACI Multi-Site architecture. Which action must be taken on each spine to accomplish this goal?

   AConfigure BGP-EVPN Router-ID
   

   BConfigure Multi-Pod Data-Plane TEP
   

   CConfigure Overlay Unicast TEP
   

   DConfigure Overlay Multicast TEP
   

   Correct answer: A

   For a full mesh Cisco ACI Multi-Site architecture, configuring the BGP-EVPN Router-ID on each spine is essential.This configuration ensures unique identification and proper routing of traffic within the overlay network1

4. Question 4

   What does the VXLAN source port add to the overlay packet forwarding when it uses the hash of Layer 2, Layer 3, and Layer 4 headers of the inner packet?

   AECMP
   

   BTCP optimization
   

   Cdisabled fragmentation
   

   Djumbo frames
   

   Correct answer: A

   The VXLAN source port adds entropy to the overlay packet forwarding by using a hash of the inner packet's Layer 2, Layer 3, and Layer 4 headers.This entropy enables Equal-Cost Multi-Path (ECMP) routing, allowing for multiple parallel paths in the network, which increases bandwidth and redundancy2.

   
   

5. Question 5

   Refer to the exhibit.

   

   Which three actions should be taken to implement the vPC in the Cisco ACI fabric? (Choose three.)

   ASelect a common vPC interface policy group
   

   BSelect individual interface profiles
   

   CSelect common interface profiles
   

   DSelect individual switch profiles
   

   ESelect common switch profiles
   

   Correct answer: A, C, E

   To implement the vPC (Virtual Port Channel) in the Cisco ACI fabric, one should select a common vPC interface policy group (Option A), select common interface profiles (Option C), and select common switch profiles (Option E). These steps ensure that both switches in a vPC domain are configured with consistent policies and profiles for interfaces and switches. This consistency is crucial for the proper functioning of a vPC setup where two or more links that are physically connected to two different Cisco ACI leaf switches appear as a single ''logical'' port channel to a third device, like the depicted WebServer.
