Question 1

Refer to the exhibits.

Is this how the switch handles the traffic?

Solution: A broadcast arrives in VLAN 10 on Switch-1. Switch 1 forwards the frame on all interfaces assigned to VLAN10, except the incoming interface. It encapsulates the broadcast with VXIAN and sends it to 192.168.1.2. but not 192.168.1.3.



Answer : B

A broadcast arrives in VLAN 10 on Switch-1. Switch 1 forwards the frame on all interfaces assigned to VLAN10, except the incoming interface. It encapsulates the broadcast with VXLAN and sends it to 192.168.1.2, but not 192.168.1.3 is not a correct explanation of how the switch handles the traffic. Switch-1, Switch-2, and Switch-3 are ArubaOS-CX switches that use VXLAN and EVPN to provide Layer 2 extension over Layer 3 networks. VXLAN is a feature that uses UDP encapsulation to tunnel Layer 2 frames over Layer 3 networks using VNIs. EVPN is a feature that uses BGP to advertise multicast information for VXLAN networks using IMET routes. Switch-1 receives a broadcast in VLAN 10, which belongs to VNI 5010. Switch-1 forwards the frame on all interfaces assigned to VLAN 10, except the incoming interface, as per normal Layer 2 switching behavior.However, Switch-1 does not encapsulate the broadcast with VXLAN and send it only to 192.168.1.2, which is Switch-3's loopback interface, but rather replicates the broadcast, encapsulates each broadcast with VXLAN, and sends the VXLAN traffic to both 192.168.1.2 and 192.168.1.3, which are Switch-3's and Switch-2's loopback interfaces respectively1.


Question 2

A customer's servers use ISCSI, and they send data and storage traffic on the same pair of I OGbE links. Is this a best practice for supporting the ISCSI requirements?

Solution: Set up dedicated switches to connect to iSCSl arrays. Connect top of rack (ToR) switches, which will support both data and storage traffic, to those dedicated switches.



Answer : A

Setting up dedicated switches to connect to iSCSI arrays and connecting top of rack (ToR) switches, which will support both data and storage traffic, to those dedicated switches is a best practice for supporting the iSCSI requirements.This provides isolation and security for the iSCSI traffic and reduces the risk of congestion or latency on the storage network1.


Question 3

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: omit the device-specific settings from the configuration plan and include them in command scripts instead.



Answer : B

Omit the device-specific settings from the configuration plan and include them in command scripts instead is not what you should do if you want to use NetEdit to manage ArubaOS-CX switches and deploy a standard config to the switches, but need the config to include a few device-specific settings such as hostname and IP address. This approach would require you to create separate command scripts for each switch, which can be tedious and error-prone.A better approach would be to use an auto config plan that uses scripts to customize the configuration for each switch based on variables such as serial number, MAC address, or user-defined parameters1.


Question 4

Does this correctly describe the ArubaOS-CX architecture?

Solution: The AtubaOS-CX software is based on the ArubaOS-Switch software and adds data center features.



Answer : B

The ArubaOS-CX software is based on the ArubaOS-Switch software and adds data center features is not a correct description of the ArubaOS-CX architecture. The ArubaOS-CX software is a new operating system that is designed for data center and campus networks. It is not based on the ArubaOS-Switch software, which is used for legacy campus switches.The ArubaOS-CX software provides advanced features such as VSX, EVPN, NAE, REST APIs, etc1.


Question 5

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

Solution: ensures a minimum bandwidth guarantee between two endpoints traffic with various 802.1 p values.



Answer : A

To ensure a minimum bandwidth guarantee between two endpoints traffic with various 802.1p values is a use case for implementing Enhanced Transmission Selection (ETS) on an ArubaOS-CX switch. ETS is a feature that provides bandwidth allocation and priority assignment for different traffic classes based on IEEE 802.1Qaz standard.ETS can help to ensure a minimum bandwidth guarantee between two endpoints by assigning different priority groups and bandwidth percentages to different traffic classes based on their 802.1p values1.


Question 6

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.



Answer : B

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.


Question 7

Is this part of the process for using NetEdit to update firmware on ArubaOS-CX switches?

Solution: Upload firmware images to the NetEdit firmware repository.



Answer : A

Uploading firmware images to the NetEdit firmware repository is part of the process for using NetEdit to update firmware on ArubaOS-CX switches1.NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface1.It also provides a firmware repository where you can store firmware images for different switch models and versions1.You can use NetEdit to upload firmware images to the repository and then deploy them to the switches1.
