External Subnets for External EPG
Shared Route Control Subnet
Shared Security Import Subnet
External Subnets for External EPG
Import Route Control Subnet
Shared Route Control Subnet
Export Route Control Subnet
Shared Security Import Subnet

Refer to the exhibit.
VM1 and VM2 are in Cisco ACI POD1 and communication takes place. Which event is triggered when VM2 is live migrated from POD1 to POD2?
Leaf 102 installs a bounce entry for VM2 pointing to the PTEP address of leaf 201.
Leaf 201 creates a tunnel with leaf 102 because of the bounced traffic that is destined to VM2.
Spines from POD2 send an MP-BGP EVPN update to the leaves in POD1 about the new location of VM2.
An MP-BGP EVPN update is received by spines in POD1 announcing the reachability of VM2 via the proxy VTEP address of the spines in POD2.
An engineer configures a Cisco ACI Multi-Pod for disaster recovery. Which action should be taken for the new nodes to be discoverable by the existing Cisco APICs?
Configure IGMPv3 on the interfaces of IPN routers that face the Cisco ACI spine.
Enable subinterfaces with dot1q tagging on all links between the IPN routers.
Enable DHCP relay on all links that are connected to Cisco ACI spines on IPN devices.
Configure BGP as the underlay protocol in IPN.
Refer to the exhibit.
Refer to the exhibit. The 0.0.0.0/0 is configured as a default static route on L3Out-1. Which action should be taken for the 0.0.0.0/0 prefix to advertise out on L3Out-2 OSPF?
Enable Export Route Control Subnet.
Enable Shared Security Import Subnet.
Enable Shared Route Control Subnet.
Enable Aggregate Export Subnet.
A packet is routed between two endpoints on different Cisco ACI leaf switches. Which VXLAN VNID is applied to the packet?
FD
EPG
VRF
BD
Refer to the exhibit.
Refer to the exhibit. A company decided to decrease its routing footprint and remove RT-2 and RT-3 devices from its data center. Because of that, the exit point must be created from all the tenants by using the common tenant. Which two configuration tasks must be completed to meet these requirements? (Choose two.)
Move subnets from all the bridge domains to the EPG level and mark them with flag Shared between VRFs.
Update the L3Out ExtEPG subnet in the common tenant with flag Shared Route Control Subnet and Aggregate Shared Routes.
Mark all subnets with flag Shared between VRFs and attach contract Ctr-3 as a provider to all the EPGs.
Change contract Ctr-3 scope to Global, consume it by all EPGs, and flag all subnets with flag Shared between VRFs.
Export contract Ctr-2 into the tenant TN-1 and attach it as a consumer to all the EPGs in the tenant TN-1.
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.)
Configure OSPF on subinterfaces on routers that are directly connected with spine nodes.
Configure ISN site extension on Cisco routers in the network.
Configure OSPF on all ISN routers.
Configure BIDIR-PIM on all ISN routers.
Configure encapsulation VLAN-4 between the routers and spine nodes.
Refer to the exhibit.
Refer to the exhibit. How are the STP BPDUs forwarded over Cisco ACI fabric?
Cisco ACI acts as the STP root for all three external switches.
STP BPDUs that are generated by Switch2 are received by Switch1 and Switch3
STP BPDUs that are generated by Switch1 are received only by Switch3.
Cisco ACI fabric drops all STP BPDUs that are generated by the external switches.
Refer to the exhibit.
Refer to the exhibit. An administrator configures inter-VRF route leaking between Production:vrfprod and Non-Production:vrf-nonprod. However, the route in the Non-Production:vrf-nonprod VRF to the production tenant is missing. Which action resolves the VRF route leaking issue?
Change the contract scope to Global.
Enable the Shared between VRFs option for the BD subnet in the production VRF.
Enable the Shared between VRFs option for the EPG subnet in the non-production VRF.
Export the contract from provider to consumer tenant.
How is broadcast forwarded in Cisco ACI Multi-Pod after ARP flooding is enabled?
Ingress replication is used on the spines to forward broadcast frames in the IPN infrastructure.
Within a pod, the ingress leaf switch floods the broadcast frame on all fabric ports.
Broadcast frames are forwarded inside the pod and across the IPN using the multicast address that is associated to the bridge domain.
For the specific bridge domain, all spines forward the broadcast frames to IPN routers.
