Which Cisco APIC configuration prevents a remote network that is not configured on the bridge domain from being learned by the fabric?

A. enable Limit IP Learning to Subnet

B. enable Unicast Routing

C. enable IP Data-plane Learning

D. enable ARP Flooding to BD

New ESXi hosts are procured in a data center compute expansion project. An engineer must update the configuration on the Cisco APIC controllers to support the addition of the new servers to the existing VMM domain. Which action should be taken to support this change?

A. Create a range of internal VLANs in the associated VLAN pool.

B. Set the encapsulation mode as VXLAN.

C. Enable infrastructure VLAN in the associated AEP.

D. Map the leaf interface selector to the AEP that is associated with the VMM domain.

A. Forwarding: Custom L2 Unknown Unicast: Hardware Proxy L3 Unknown Multicast Flooding: Flood Multi Destination Flooding: Flood in BD ARP Flooding: Enabled

B. Forwarding: Custom L2 Unknown Unicast: Flood L3 Unknown Multicast Flooding: Flood Multi Destination Flooding: Flood in BD ARP Flooding: Enabled

C. Forwarding: Custom L2 Unknown Unicast: Hardware Proxy L3 Unknown Multicast Flooding: Flood Multi Destination Flooding: Flood in BD ARP Flooding: Disabled

D. Forwarding: Custom L2 Unknown Unicast: Flood L3 Unknown Multicast Flooding: Flood Multi Destination Flooding: Flood in BD ARP Flooding: Disabled

B. PIM ASM multicast routing

C. BGP routing

D. VLAN ID 4

E. OSPF routing

Refer to the exhibit.

An engineer configured subnets on the external EPG called L3OUT_CORE. The external endpoints in the 10.1.0.0/24 subnet can reach internal endpoints, but the external endpoints in the 172.16.1.0/24 subnet are unreachable. Which set of actions enables the connectivity?

A. Delete both external EPG subnets. Create the 0.0.0.0/1 subnet.

B. Delete the external EPG subnet 0.0.0.128/1. Create the 128.0.0.0/1 subnet.

C. Delete both external EPG subnets. Create the 0.0.0.0/0 subnet.

D. Delete the external EPG subnet 0.0.0.0/0. Create the 0.0.0.0/128 subnet.

A network engineer must integrate VMware vCenter cluster with Cisco ACI. The requirement is for the management traffic of the hypervisors and VM controllers to use the virtual switch associated with the Cisco Application Policy. The EPG called "Vmware-MGMT" with VLAN 300 has been created for this purpose. Which set of steps must be taken to complete the configuration?

A. Add VLAN 300 with static allocation to the VLAN POOL that is used for VMM integration. Attach the VMM domain to the target EPG with resolution preprovision, mode static, untagged access VLAN, and Port-Encap 300.

B. Associate the target EPG with the VMM domain with default settings. Enable Infrastructure VLAN on AAEP used toward VMware hypervisors.

C. Enable Infrastructure VLAN on AAEP used toward VMware hypervisors. Associate the target EPG with the VMM domain with default settings.

D. Enable Infrastructure VLAN on AAEP used toward VMware hypervisors. Create a static binding in the target EPG toward VMware hypervisors with VLAN 300, untagged access VLAN, and Untagged 802.1P mode.

What two actions should be taken to deploy a new Cisco ACI Multi-Pod setup? (Choose two.)

A. Configure MP-BGP on IPN routers that face the Cisco ACI spines.

B. Connect all spines to the IPN.

C. Configure anycast RP for the underlying multicast protocol

D. Configure the TEP pool of the new pod to be routable across the IPN.

E. Increase interface MTU for all IPN routers to support VXLAN traffic.

Refer to the exhibit.

An administrator configures inter-VRF route leaking between Production:vrf-prod 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?

A. Change the contract scope to Global.

B. Enable the Shared between VRFs option for the BD subnet in the production VRF.

C. Enable the Shared between VRFs option for the EPG subnet in the non-production VRF.

D. Export the contract from provider to consumer tenant.

Where are STP BPDUSs flooded in Cisco ACI fabric?

A. in the access encapsulation VLAN part of different VLAN pools

B. in the bridge domain VLAN

C. in the native VLAN ID

D. in the VNID that is assigned to the FD VLAN

Which protocol is used in the Cisco ACI fabric for automatic discovery?

A. LLDP

B. IS-IS

C. CFS

D. COOP
