NEW QUESTION # 73
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 binding
- B. LACP passive
- C. MAC pinning
- D. LACP active
Answer: C
Explanation:
For the Cisco ACI leaf to learn individual MAC addresses from the same physical port, "MAC pinning" mode must be enabled in the vSwitch policy configuration. This mode allows each ESXi vSwitch port group to pin to a specific uplink or set of uplinks, enabling independent MAC address learning for each pinned uplink, which is essential for distinguishing multiple VMs on an ESXi host by the leaf switch.

NEW QUESTION # 74
An engineer configures Cisco ACI Multi-Site and must specify the control plane TEP IP for spines. Which statement describes control plane TEP IP in this situation?
- A. The unique IP address is defined on each spine node that belongs to a fabric and is used to establish VXLAN adjacencies with the spine nodes in remote sites.
- B. The common anycast address is shared by all the spine nodes at the same site and is used lo source and receive unicast VXLAN data plane traffic.
- C. The unique IP address is defined on each spine node that belongs to a fabric and is used to establish MP-BGP EVPN and VPNv4 adjacencies with the spine nodes in remote sites.
- D. The common anycast address is shared by all the spine nodes in the same site and is used to perform headend replication for BUM traffic.
Answer: C
Explanation:
The control plane TEP (Tunnel Endpoint) IP address is a unique IP address assigned to each spine node within a Cisco ACI fabric. This IP address is used to establish MP-BGP EVPN (Multiprotocol Border Gateway Protocol Ethernet VPN) and VPNv4 (VPN version 4) adjacencies with the spine nodes in remote sites when configuring Cisco ACI Multi-Site. The control plane TEP IP enables the spine nodes to exchange routing information and network reachability for seamless integration of multiple sites into a single ACI fabric.

Answer: D
NEW QUESTION # 76
What is the advantage of implementing an active-active firewall cluster that is stretched across separate pods when anycast services are configured?
- A. A cluster can be deployed in transparent mode across pods.
- 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 different MAC/IP combination can be configured for the firewall in each pod.
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.

In a Cisco ACI Multi-Site fabric, the Inter-Site BUM Traffic Allow option is enabled in a specific stretched bridge domain. What is used to forward BUM traffic to all endpoints in the same broadcast domain?
- A. egress replication on the destination leaf switches
- B. egress replication on the source leaf switches
- C. ingress replication on the spines in the destination site
- D. ingress replication on the spines in the source site
Answer: D
Explanation:
Cisco ACI Multi-Site design uses the ingress replication function on the spine nodes of the source site to replicate BUM traffic to all the remote sites.

NEW QUESTION # 82
An engineer must limit local and remote endpoint learning to the bridge domain subnet. Which action should be taken inside the Cisco APIC?
- A. Enable Enforce Subnet Check
- B. Enable Limit IP Learning to Subnet
- C. Disable Endpoint Dataplane Learning
- D. Disable Remote EP Learn
Answer: A
Explanation:
To limit both local and remote endpoint learning to instances where the source IP address belongs to a bridge-domain subnet in the VRF instance, the action that should be taken inside the Cisco APIC is to enable the "Enforce Subnet Check" feature. This configuration ensures that IP addresses outside the configured subnets for the bridge domain are not learned, preventing mis-learning of IP addresses that do not belong to the fabric12.
NEW QUESTION # 83
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. Create a vzAny contract
- C. Set policy control enforcement to Unenforced
- D. Select the Intra-EPG Isolation checkbox.
- E. Enable the Preferred Group option on EPGs 1 to 50.
Answer: A,E
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.
