A data center has a three-tier topology with ArubaOS-CX switches at each layer, is this a use case for implementing Virtual Switching Extension (VSX) at the core?

Solution: The aggregation layer operates at Layer 2 only, and the core provides Layer 2 and Layer 3 functions.

  1. Yes
  2. No

Answer(s): B

Explanation:

The aggregation layer operates at Layer 2 only, and the core provides Layer 2 and Layer 3 functions is not a use case for implementing Virtual Switching Extension (VSX) at the core for a data center that has a three-tier topology with ArubaOS-CX switches at each layer. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. VSX can be implemented at any layer of the data center network, but it is more common to implement it at the aggregation or leaf layer, where it can provide Layer 2 and Layer 3 functions. The core layer typically operates at Layer 3 only and does not require VSX2.



Your task is to configure an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. Is this statement about EVPN and IPv6 correct?

Solution: The IPv6 and IPv4 overlay networks can be encapsulated with VXLAN and transmitted through the underlay network.

  1. Yes
  2. No

Answer(s): A

Explanation:

The IPv6 and IPv4 overlay networks can be encapsulated with VXLAN and transmitted through the underlay network is a true statement about EVPN and IPv6 for configuring an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. VXLAN is a feature that provides Layer 2 extension over Layer 3 networks using UDP encapsulation. VXLAN can support both IPv4 and IPv6 overlay networks over an IPv4 or IPv6 underlay network2.



Your task is to configure an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. Is this statement about EVPN and IPv6 correct?

Solution: Different virtual MAC must be used for IPv4 and IPv6 Active Gateway.

  1. Yes
  2. No

Answer(s): B

Explanation:

Different virtual MAC must be used for IPv4 and IPv6 Active Gateway is not a true statement about EVPN and IPv6 for configuring an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. Active Gateway is a feature that provides first-hop redundancy for hosts connected to VTEPs using anycast gateway addresses. Active Gateway can use the same virtual MAC address for both IPv4 and IPv6 protocols on the same VNI2.



Refer to the exhibit.



You want to enable devices in VRF B and VRF C to reach shared resources in VRF

  1. is this a valid strategy for meeting this goal?
    Solution: Create a separate OSPF process for each VRF on Switch-1. Then redistribute each process into the other VRFs' processes.
  2. Yes
  3. No

Answer(s): B

Explanation:

Create a separate OSPF process for each VRF on Switch-1. Then redistribute each process into the other VRFs' processes is not a valid strategy for meeting this goal of enabling devices in VRF B and VRF C to reach shared resources in VRF A. This strategy would create unnecessary complexity and overhead on Switch-1, and it would not guarantee optimal routing between the VRFs. A better strategy would be to use inter-VRF routing or route leaking on Switch-1, which allows direct communication between different VRFs without requiring redistribution1.
