Question

In the Cisco data center technology called API, which of the following are defined by network application policies and are implemented by spine leaf nodes?

a) EPG
b) APIC
c) ASIC
d) None of the above

Answer 1

In Cisco's ACI, network application policies are defined by Endpoint Groups (EPGs) and implemented within the spine-leaf architecture of the data center.

Step-by-step explanation:

In the context of the Cisco data center technology known as ACI (Application Centric Infrastructure), network application policies are primarily defined by entities named Endpoint Groups (EPGs). EPGs are logical entities that can contain a variety of objects, such as virtual machines, servers, or even entire subnets. The spine-leaf architecture is a key feature of Cisco's ACI, and it facilitates the communication of EPGs, ensuring that policy enforcement is consistent across the network.

When you specifically ask about what is implemented by spine-leaf nodes based on network application policies, the answer would be a) EPG (Endpoint Group). The APIC (Application Policy Infrastructure Controller) is the centralized software controller that manages the network policies, while ASIC (Application-specific Integrated Circuit) is hardware that can be used in networking devices for processing data efficiently, but it is not directly defined by network application policies like EPGs are.
