Cisco 300-630 Dumps Questions Answers

To implement the vPC (Virtual Port Channel) in the Cisco ACI fabric, one should select a common vPC interface policy group (Option A), select common interface profiles (Option C), and select common switch profiles (Option E). These steps ensure that both switches in a vPC domain are configured with consistent policies and profiles for interfaces and switches. This consistency is crucial for the proper functioning of a vPC setup where two or more links that are physically connected to two different Cisco ACI leaf switches appear as a single “logical” port channel to a third device, like the depicted WebServer.

 The output shows details of tunnel 6 within a Cisco ACI fabric. The transport protocol is listed as “isvlan,” which is typically associated with the GRE protocol in Cisco ACIterminology. GRE, a tunneling protocol developed by Cisco, encapsulates various network layer protocols inside virtual point-to-point links over an IP internetwork. References: Implementing Cisco Application Centric Infrastructure Official Cert Guide

In the Cisco ACI fabric, to ensure that the IP address of Server S1 is learned and the IP addresses of BC1 and BC2 are not learned, one must limit IP learning to a specific subnet and suppress ARP responses from BC1 and BC2. By checking the “Limit IP learning to subnet” box (Option A), it ensures that only IPs within a defined subnet are learned, which would include Server S1’s IP but exclude BC1 and BC2 if they are outside of this subnet.Suppressing ARP response on BC1 and BC2 (Option D) prevents these devices from responding to ARP requests, which in turn prevents their IPs from being learned by other devices in the network. References := ( Implementing Cisco Application Centric Infrastructure Official Cert Guide )
