Question 1

An engineer configures Cisco ACI Multi-Site and must specify the control plane TEP IP for spines. Which statement describes control plane TEP IP in this situation?

AThe unique IP address is defined on each spine node that belongs to a fabric and is used to establish MP-BGP EVPN and VPNv4 adjacencies with the spine nodes in remote sites.

BThe unique IP address is defined on each spine node that belongs to a fabric and is used to establish VXLAN adjacencies with the spine nodes in remote sites.

CThe common anycast address is shared by all the spine nodes in the same site and is used to perform headend replication for BUM traffic.

DThe common anycast address is shared by all the spine nodes at the same site and is used lo source and receive unicast VXLAN data plane traffic.

Answer : A

The control plane TEP (Tunnel Endpoint) IP address is a unique IP address assigned to each spine node within a Cisco ACI fabric. This IP address is used to establish MP-BGP EVPN (Multiprotocol Border Gateway Protocol Ethernet VPN) and VPNv4 (VPN version 4) adjacencies with the spine nodes in remote sites when configuring Cisco ACI Multi-Site. The control plane TEP IP enables the spine nodes to exchange routing information and network reachability for seamless integration of multiple sites into a single ACI fabric.Reference:= Implementing Cisco Application Centric Infrastructure Official Cert Guide

Question 2

Which protocol must be applied between the inter-pod network and spines within each pod to allow broadcast traffic replication between Cisco ACI pods?

AMSDP Peering

BMulticast BGP

CBidirectional PIM

DIGMP Registration

Answer : C

Bidirectional Protocol Independent Multicast (Bidirectional PIM) is used between the inter-pod network (IPN) and spines within each pod in a Cisco ACI environment to allow broadcast traffic replication between pods. This protocol is designed to efficiently route multicast traffic in scenarios where the same data is being sent to multiple receivers, which aligns with the need for broadcast traffic replication in an interconnected multi-pod ACI architecture.Reference:= ( Implementing Cisco Application Centric Infrastructure Official Cert Guide )

Question 3

An engineer implements the Cisco ACI solution and needs to confirm that the leaf switch correctly learns the remote endpoint MAC. Which information must be included in the VXLAN packet that is received from the Cisco ACI spine for the Cisco ACI leaf to learn MAC as a remote endpoint?

AVRF

Bapplication profile

Cbridge domain

DEPG

Answer : C

For a Cisco ACI leaf switch to correctly learn the remote endpoint MAC, the VXLAN packet received from the Cisco ACI spine must includebridge domaininformation.The bridge domain contains the Layer 2 forwarding context, which allows the leaf switch to learn and associate the MAC address with the correct bridge domain3.

Question 4

Refer to the exhibit.

Which configuration must be implemented to allow intra-VRF transit routing between the two external routers?

ADeploy both areas under the same L3Out policy

BChange one of the areas to area 0

CConfigure OSPF virtual links

DModify L3Out 1 to use the same OSPF area as L3Out 2

Answer : C

For intra-VRF transit routing between two external routers in different OSPF areas, OSPF virtual links are required. They connect non-contiguous areas to the backbone area, ensuring all areas can communicate even if not directly connected.

Question 5

What is a design implication for Cisco ACI using an application-centric approach?

AMultiple VLANs and/or multiple EPGs are under one bridge domain

BVLAN numbers are in the names of the bridge domain and EPG objects

COne EPG is mapped to multiple bridge domains

DOne VLAN equals one EPG equals one bridge domain

Answer : A

Using an application-centric approach in Cisco ACI means that multiple VLANs and/or multiple EPGs can be grouped under one bridge domain. This approach aligns network constructs with application requirements, enabling more efficient and flexible network configurations.

Question 6

A company must connect three Cisco ACI data centers by using Cisco ACI Multi-Site. An engineer must configure the Inter-Site Network (ISN) between the existing sites. Which two configuration steps must be taken to implement the ISN? (Choose two.)

AConfigure encapsulation VLAN-4 between the routers and spine nodes.

BConfigure OSPF on subinterfaces on routers that are directly connected with spine nodes

CConfigure ISN site extension on Cisco routers in the network

DConfigure OSPF on all ISN routers.

EConfigure BIDIR-PIM on all ISN routers.

Answer : B, E

For the ISN implementation between Cisco ACI data centers using Multi-Site, OSPF must be configured on subinterfaces for dynamic routing, and BIDIR-PIM must be set up on all ISN routers for efficient bidirectional multicast traffic routing.Reference:= (Implementing Cisco Application Centric Infrastructure Official Cert Guide)

Question 7

Which approach does Cisco ACI use to achieve multidestination packet forwarding between leaf switches in the same fabric?

AMap VXLAN VTEP to the multicast group

BMap VXLAN to PIM-SM protocol

CMap VXLAN VNI to the multicast group

DMap VXLAN to PIM-DM protocol

Answer : C

Cisco ACI uses a mapping of VXLAN Virtual Network Identifier (VNI) to multicast groups to facilitate multidestination packet forwarding between leaf switches within the same fabric.This approach allows for efficient communication and data packet distribution to multiple destinations simultaneously1.
