Cisco 700-703 Cisco Application Centric Infrastructure for Field Engineers Exam Exam Practice Test

An AEP is required to deploy any VLAN pools on the leaf switches. It is possible to reuse the encapsulation pools (for example, VLAN) across different leaf switches. An AEP implicitly provides the scope of the VLAN pool (associated to the domain) to the physical infrastructure.

An override policy at AEP can be used to specify a different physical interface policy for a VMM domain. This policy is useful in scenarios where a hypervisor is connected to the leaf switch through an intermediate Layer 2 node, and a different policy is desired at the leaf switch and hypervisor physical ports. For example, you can configure LACP between a leaf switch and a Layer 2 node. At the same time, you can disable LACP between the hypervisor and the Layer 2 switch by disabling LACP under the AEP override policy.

The layer 2 is Data link layer

Labels, which are used optionally to group objects such as subjects and EPGs for the purpose of further defining policy enforcement

ACI Application Network Profiles are the grouping of one or more EPGs and the policies that define how they communicate.
