Question 1

AtubaOS-CX switches are acting as Virtual Extensible LAN (VXLAN) Tunnel Endpoints (VTEPs) WITHOUT Ethernet VPN (EVPN).

Does this correctly describe how the VTEPs handle VXLAN traffic forwarding?

Solution: VTEPs that use headend replication forward broadcasts as unicast packets to each VTEP in the same VNI.



Answer : A

Headend replication is a method of handling BUM traffic in VXLAN networks without EVPN, where the ingress VTEP replicates every BUM packet and sends them as a separate unicast to the remote egress VTEPs in the same VNI1. This avoids the need for multicast routing in the underlay network, but it can increase the load on the ingress VTEP. Therefore, this correctly describes how the VTEPs handle VXLAN traffic forwarding without EVPN.


Question 2

AtubaOS-CX switches are acting as Virtual Extensible LAN (VXLAN) Tunnel Endpoints (VTEPs) WITHOUT Ethernet VPN (EVPN).

Does this correctly describe how the VTEPs handle VXLAN traffic forwarding?

Solution: VTEPs that use headend replication forward broadcast as multicast to each VTEP in the same VNI.



Answer : A

VXLAN is a tunneling protocol that encapsulates layer 2 traffic over an IP network using VXLAN Network Identifiers (VNIs) to identify different layer 2 segments. VXLAN Tunnel Endpoints (VTEPs) are devices that perform the encapsulation and decapsulation of VXLAN packets. VTEPs can use different methods to handle broadcast, unknown unicast, and multicast (BUM) traffic within a VNI.One of these methods is headend replication, which means that the VTEP that receives a BUM packet replicates it and sends it as a unicast to each remote VTEP in the same VNI1. This method does not require multicast routing in the underlay network, but it can increase the load on the ingress VTEP. Therefore, this correctly describes how the VTEPs handle VXLAN traffic forwarding without EVPN.


Question 3

Is this a use case for implementing Enhanced Transmission Selection (ETS) on an ArubaOS-CX switch?

Solution: to enable the switch to assign the correct priority and bandwidth to traffic that it transmits to servers



Answer : A

Enhanced Transmission Selection (ETS) is a network scheduling algorithm that allows the switch to assign different priority and bandwidth values to different traffic classes1. This can be useful for transmitting traffic to servers that have different requirements for latency, jitter, or throughput. For example, ETS can prioritize voice or video traffic over data traffic, or allocate more bandwidth to backup or replication traffic.ETS is configured using the Data Center Bridging Exchange (DCBx) protocol, which advertises the configuration to peer devices2. Therefore, implementing ETS on an ArubaOS-CX switch is a valid use case for enabling the switch to assign the correct priority and bandwidth to traffic that it transmits to servers.


Question 4

Is this how you should position switches in the ArubaOS-CX portfolio tor data center networks?

Solution: Deploy Aruba CX 8400 switches as core switches for very large three-tier data center networks.



Answer : A

Deploying Aruba CX 8400 switches as core switches for very large three-tier data center networks is how you should position switches in the ArubaOS-CX portfolio for data center networks.ArubaOS-CX is an operating system that provides advanced features and automation capabilities for data center networks1.It runs on various switch models that are designed for different roles and scenarios in the data center1.Aruba CX 8400 switches are modular switches that offer high performance, scalability, and reliability for the core layer of very large three-tier data center networks1. The statement is true because it correctly describes how to position Aruba CX 8400 switches in the ArubaOS-CX portfolio for data center networks.


Question 5

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: IPv6 protocol can be encapsulated in the underlay network's IPv4 packets.



Answer : B

IPv6 protocol cannot be encapsulated in the underlay network's IPv4 packets.EVPN is a protocol that provides layer 2 and layer 3 services over an IP network1.It uses VXLAN tunnels to encapsulate Ethernet frames in UDP packets and transport them across the underlay network1.The underlay network can use either IPv4 or IPv6 protocol, but it must match the protocol used by the VXLAN tunnels1. The statement is false because it implies that IPv6 protocol can be encapsulated in IPv4 packets, which is not possible.


Question 6

You are using NetEdit to manage AruDaOS-CX switches. You want to deploy a standard config to the switches, but need the config to include a few device-specific settings such as hostname and IP address.

Is this what you should do?

Solution: Create two configuration plans, one with the standard config and one with the device-specific settings.



Answer : B

Creating two configuration plans, one with the standard config and one with the device-specific settings, is not what you should do.NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface1.It also provides a plan feature that lets you create containers to group devices and execute operations on them, such as deploying, committing, or rolling back device configuration or firmware1. However, you do not need to create two configuration plans for your scenario.You can create one configuration plan with the standard config and use variables to define the device-specific settings1.Variables are placeholders that can be replaced with different values for different devices1.This way, you can deploy a standard config with device-specific settings using one configuration plan1.


Question 7

Is this a way that Virtual Switching Extension (VSX) differs from Virtual Switching Framework (VSF)?

Solution: VSX features a dual control plane while VSF features a single control plane.



Answer : A

VSX features a dual control plane while VSF features a single control plane.VSX and VSF are both high availability solutions that provide redundancy and load balancing across a pair of switches1.However, VSX features a dual control plane, which means that each switch has its own independent configuration and state information1.VSF features a single control plane, which means that one switch acts as the commander and synchronizes the configuration and state information to the other switch1. The statement is true because it correctly describes the difference between VSX and VSF control planes.
