Section: Multisite
NEW QUESTION # 40
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. Enable the Preferred Group option on EPGs 1 to 50
- B. Select the Intra-EPG Isolation checkbox.
- C. Set policy control enforcement to Unenforced.
- D. Create a standard contract between EPG 51 and EPG 10.
- E. Create a vzAny contract.
Answer: A,D
Explanation:
To meet the requirements specified, two actions must be taken: B. Create a standard contract between EPG 51 and EPG 10 to explicitly allow communication between these two EPGs. A contract in Cisco ACI defines the communication policy between EPGs, and by creating a standard contract, specific communication can be permitted. E. Enable the Preferred Group option on EPGs 1 to 50 to allow communication within this group of EPGs. The Preferred Group feature in ACI allows all EPGs within the group to communicate with each other without the need for explicit contracts, while still enforcing contracts for communication with EPGs outside the group.

NEW QUESTION # 41
Refer to the exhibit.
An engineer extends a Cisco ACI Multi-Pod setup to a Cisco ACI Multi-Site implementation. Which action allows the interconnection?
- A. Connect all spines to the IPN and ISN
- B. Filter the advertisement of the Site 2 TEP pool into the IPN
- C. Configure BIDIR-PIM in the IPN and ISN
- D. Use dedicated uplinks on Site 1 spines for ISN connections

NEW QUESTION # 42
What are two P8R characteristics of the Cisco ACI Active-Active Across Pods deployment mode in Cisco ACI Multi-Pod design? (Choose two.)
- A. The connection state is unsynchronized.
- B. Traffic is dynamically redirected to the firewall that owns the connection.
- C. Deployment occurs in transparent mode.
- D. Deployment occurs in go-to mode only.
- E. This mode causes the traffic to flow asymmetrically.
Answer: A,B
Explanation:
In an Active-Active Across Pods deployment mode, traffic is intelligently redirected to the firewall that currently owns the connection state, allowing for efficient use of network resources. Additionally, the connection state being unsynchronized means that each pod can independently manage its connections without relying on a centralized state, enhancing the resilience and scalability of the network1.

NEW QUESTION # 45
Refer to the exhibit.
Server A is connected to the Cisco ACI fabric using two teamed interfaces. One interface in a team is configured as active and the other remains in standby mode. When a failover occurs and the standby interface becomes active, it uses its built-in MAC address to send traffic. Which bridge domain configuration must be applied to resolve the issue?
- A. Configure Hardware proxy.
- B. Activate Limit IP Learning to Subnet.
- C. Set L2 Unknown Unicast to Flood
- D. Enable ARP flooding.
Answer: D
Explanation:
When Server A is connected to the Cisco ACI fabric using teamed interfaces with one active and one standby interface, enabling ARP flooding ensures that the ACI fabric can learn about the new active interface after a failover. This allows for seamless communication continuity even when the standby interface becomes active and starts sending traffic with its built-in MAC address.
NEW QUESTION # 46
Refer to the exhibit. Which method does Cisco ACI fabric use to forward L2 Unknown Unicast packets?
- A. Traffic is flooded to all Layer 2 ports of ACI fabric.
- B. Packets are dropped if dMAC is absent in COOP.
- C. The source leaf sends the traffic to all ports in BD.
- D. The traffic is flooded using VRF Outer Multicast Group ID.
Answer: B
NEW QUESTION # 47

- A. Apply Both Direction ENABLED and Reverse Port Filter ENABLED
- B. Apply Both Direction DISABLED and Reverse Port Filter ENABLED
- C. Apply Both Direction ENABLED and Reverse Port Filter DISABLED
- D. Apply Both Direction DISABLED and Reverse Port Filter DISABLED

NEW QUESTION # 48
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. Local traffic in a pod is load-balanced between the clustered firewalls.
- C. The local pod anycast node is preferred by the local spines.
- D. A cluster can be deployed in transparent mode across pods.
Answer: C
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.
