How is broadcast forwarded in Cisco ACI Multi-Pod after ARP flooding is enabled?

A. For the specific bridge domain, all spines forward the broadcast frames to IPN routers

B. Broadcast frames are forwarded inside the pod and across the IPN using the multicast address that is associated to the bridge domain

C. Within a pod, the ingress leaf switch floods the broadcast frame on all fabric ports

D. Ingress replication is used on the spines to forward broadcast frames in the IPN infrastructure

Which firewall connection allows for the integration of service nodes in transparent mode with a Cisco ACI Multi-Pod setup?

A. active-standby mode across pods

B. active-active mode per pods for communication between internal endpoints

C. active-standby mode per pods for communication between endpoints and external networks

D. active-active mode across pods

What is the advantage of implementing an active-active firewall cluster that is stretched across separate pods when anycast services are configured?

A. A different MAC/IP combination can be configured for the firewall in each pod.

B. The local pod anycast node is preferred by the local spines.

C. A cluster can be deployed in transparent mode across pods.

D. Local traffic in a pod is load-balanced between the clustered firewalls.

What are two characteristics of network-centric design in Cisco ACI? (Choose two.)

A. There is open communication between EPGs

B. EPGs are used for microsegmentation

C. EPGs are different security zones

D. Applications define the network requirements

E. A bridge domain has one subnet and one EPG

Refer to the exhibit.

An engineer is configuring a vSwitch policy in the existing Cisco ACI fabric. The requirement is for the Cisco ACI leaf to learn individual MAC addresses from the same physical port. Which vSwitch policy configuration mode must be enabled to meet this requirement?

A. MAC pinning

B. MAC binding

C. LACP passive

D. LACP active

Which action reduces the impact on workload when migrating from the existing Cisco NX-OS VXLAN network infrastructure to the Cisco ACI fabric?

A. Disable bridge domain unicast routing while a default gateway is in VXLAN infrastructure

B. Set the default gateway in the Cisco ACI and VXLAN fabrics

C. Use ACI spines for the Cisco ACI and VXLAN fabrics

D. Configure vPC between the standalone Nexus and the Cisco ACI leaf

An engineer created a Cisco ACI environment in which multiple tenants reuse the same contract. The requirement is to prevent inter-tenant communication. Which action meets this requirement?

A. Create the contract in the user tenant with the scope set to VRF and exported to other tenants

B. Create the contract in the common tenant with the scope set to Tenant

C. Create the contract in the user tenant with the scope set to Global and exported to other tenants

D. Create the contract in the common tenant with the scope set to Global

As part of a newly deployed ACI fabric, a pair of border leaf switches have been deployed to provide shared services for all tenants. The configured L3Out runs OSPF as the routing protocol. The requirement is to advertise the routes from the border leaf switches to the compute leaf switches. Which configuration must be implemented to meet these requirements?

A. Configure a BGP route reflector policy for the Cisco ACI pod

B. Define the shared L3Out in the common tenant

C. Enable Import Route Control Enforcement in the L3Out policy

D. Define the consumer subnet under the consumer EPG

An engineer must allow routes learned from one L3Out to be advertised out another L3Out. The engineer does not have an explicit list of all the routes that must be advertised out, however, they know that they are all part of the 10.16.0.0/16 CIDR block. Which attributes must be selected under Ext-EPG to allow the necessary routes to be advertised out?

A. Enable Export Route Control Subnet and enable Aggregate Export

B. Disable Shared Route Control Subnet and enable Aggregate Shared Routes

C. Enable Export Route Control Subnet and disable Aggregate Shared Routes

D. Enable Export Route Control Subnet and enable Shared Route Control Subnet

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

A. Configure anycast RP for the underlying multicast protocol

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

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

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

E. Connect all spines to the IPN
