NEW QUESTION # 72
What is a characteristic of a stretched bridge domain solution between Cisco ACI sites with Layer 2 flood disabled?
- A. The application profile that is associated to the bridge domain have local significance in each site.
- B. The tenant and VRF that associated to the bridge domain have local significance in each site.
- C. IP mobility is ensured between sites for disaster recovery.
- D. Headend replication is used for BUM traffic between sites.
Answer: D
Explanation:
In a stretched bridge domain solution between Cisco ACI sites with Layer 2 flood disabled, headend replication is used for broadcast, unknown unicast, and multicast (BUM) traffic between sites. This approach optimizes traffic flow and reduces unnecessary flooding across the network1.

NEW QUESTION # 77
Which action extends an EPG outside of the Cisco ACI fabric?
- A. Enable a routing protocol on the border leaf.
- B. Create a Layer 3 port.
- C. Manually assign a port to a VLAN and map the VLAN to an EPG
- D. Extend the bridge domain to an outside network.
Answer: D
NEW QUESTION # 78
Which PIM version must be configured in the Inter-Pod Network to allow broadcast, unknown unicast. and multicast flooding between Cisco ACI pods?
- A. Source Specific Multicast
- B. PIM sparse mode
- C. Bidirectional PIM
- D. PIM dense mode
Answer: B
Explanation:
Protocol Independent Multicast sparse mode (PIM-SM) is designed for efficient routing to multiple receivers in a multicast group across an inter-pod network (IPN). PIM sparse mode is best suited for environments where receivers are dispersed because it allows for explicit join messages to control the flow of traffic. This makes it ideal for scenarios where broadcast, unknown unicast, and multicast flooding between Cisco ACI pods is required.

NEW QUESTION # 79
How does Cisco ACI manage the STP BPDUs between two pods?
- A. Cisco ACI spines suppress STP BPDUs to be forwarded to other pods
- B. Cisco ACI spines perform ingress replication for STP BPDUs
- C. BPDUs are forwarded over IPN using the bridge domain GIPo multicast address
- D. Special multicast group 239.255.255.255 is used to forward STP BPDUs
Answer: C
NEW QUESTION # 80
What is the purpose of the Forwarding Tag (FTAG) in Cisco ACI?
- A. FTAG is used in Cisco ACI to add a label to the VXLAN traffic in the fabric to apply the correct policy.
- B. FTAG trees in Cisco ACI are used to load balance unicast traffic.
- C. FTAG trees in Cisco ACI are used to load balance mutli-destination traffic.
- D. FTAG is used in Cisco ACI to add a label to the iVXLAN traffic in the fabric to apply the correct policy.
Answer: C

NEW QUESTION # 81
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. Disable Shared Route Control Subnet and enable Aggregate Shared Routes
- B. Enable Export Route Control Subnet and disable Aggregate Shared Routes
- C. Enable Export Route Control Subnet and enable Shared Route Control Subnet
- D. Enable Export Route Control Subnet and enable Aggregate Export
Answer: D

NEW QUESTION # 83
Which action should be taken in Cisco ACI to reassign a unique globally scoped pcTag to an EPG that provides a global contract?
- A. Configure subnets that are shared between VRFs
- B. Configure subnets that advertise externally
- C. Configure subnets that are treated as virtual IP

NEW QUESTION # 84
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. Local traffic in a pod is load-balanced between the clustered firewalls.
- D. A cluster can be deployed in transparent mode across pods.
Answer: B
Explanation:
Implementing an active-active firewall cluster stretched across separate pods with anycast services configured offers several advantages, one of which is that it allows for optimized routing within the Cisco ACI fabric.
When anycast services are used, each pod can have its own anycast node (firewall instance), and due to routing preferences set within ACI's spine switches, they will prefer their local pod's anycast node for routing decisions. This preference enhances efficiency by reducing cross-pod traffic and improving response times since local spines direct traffic to their respective local pod's anycast nodes.

NEW QUESTION # 85
A Cisco ACI fabric is configured with these settings:
- A single VRF exists that contains 100 EPGs.
- EPGs 1 to 50 must be permitted to communicate.
- EPGs 51 to 100 must NOT be allowed to communicate with EPGs 1 to 50.
- EPG 51 must be allowed to communicate with EPG 10
Which two actions must be taken to accomplish these requirements? (Choose two.)
- A. Set policy control enforcement to Unenforced
- B. Select the Intra-EPG Isolation checkbox.
- C. Create a standard contract between EPG 51 and EPG 10.
- D. Enable the Preferred Group option on EPGs 1 to 50.
- E. Create a vzAny contract
Answer: C,D
Explanation:
Preferred Group (PG) feature allows you to specify a set of EPGs that are part of the same VRF to allow full communication between them with no need for contracts to be created.
