NEW QUESTION # 43
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?

NEW QUESTION # 44
Exhibit.
Refer to the exhibit. An engineer must implement a solution to ensure that ingress and egress traffic flows are symmetric for all stretched bridge domains in the customer multisite architecture. Which configuration accomplishes this goal?
- A. Add a new stretched external EPG to the existing L3outs.
- B. Enable anycast services to the firewalls in both fabrics.
- C. Configure host route advertisement on the bridge domains.
- D. Implement a policy-based redirect using a service graph.
Answer: C
Explanation:
In a Cisco ACI multisite setup, symmetric ingress and egress traffic flows for stretched bridge domains are essential for consistent network behavior. Configuring host route advertisement on the bridge domains allows each site to advertise its local endpoints' routes. This ensures that return traffic is directed to the originating site, maintaining symmetric traffic flow. When host routes are advertised from the bridge domains, it allows for more granular control of traffic, ensuring that packets take the same path into and out of the network, which is particularly important in stretched scenarios whereapplications might span multiple sites.

NEW QUESTION # 46
Refer to the exhibit.
Which configuration mode must be selected for the VMM vSwitch Port Channel policy to avoid MAC flapping on the Cisco UCS Fls and Cisco ACI leaf switches?
- A. LACP Active
- B. MAC Pinning
- C. Static Channel - Mode On
- D. LACP Passive
Answer: B
Explanation:
To prevent MAC flapping on Cisco UCS Fabric Interconnects and ACI leaf switches, MAC Pinning should be selected for the VMM vSwitch Port Channel policy. This ensures consistent uplink usage for each virtual machine's traffic, avoiding MAC address movement across multiple uplinks.

NEW QUESTION # 54
An engineer deployed a Cisco ACI fabric and noticed that the fabric learns endpoints from subnets that are not configured on a bridge domain. To meet strict security requirements, the engineer must prevent this behavior. Which action must be taken to prevent this behavior?

Answer: B
NEW QUESTION # 55
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. Create a standard contract between EPG 51 and EPG 10.
- B. Set policy control enforcement to Unenforced.
- C. Select the Intra-EPG Isolation checkbox.
- D. Create a vzAny contract.
- E. Enable the Preferred Group option on EPGs 1 to 50
Answer: A,E
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.

A Cisco ACI fabric must be integrated with VMware. Leaf1 and Leaf2 are connected to S1 using a VPC. The object VMware Virtual Distributed switch VPC Policy group type has been created in the fabric. Which mode must be set for the port-channel policy to allow the failover and the full use of the bandwidth in both directions?
- A. Static channel - Mode On
- B. MAC Pinning
