Question 1

You want to use NetEdit to configure an AtubaOS-CX switch.

Is this a minimum requirement for setting up communications between the switch and NetEdit?

Solution: Make sure that the SSH server is enabled.



Answer : A

The solution is correct because making sure that the SSH server is enabled is a minimum requirement for setting up communications between the switch and NetEdit. NetEdit uses SSH to establish a secure connection to the switch and execute commands on it. Therefore, making sure that the SSH server is enabled is necessary for setting up communications between the switch and NetEdit.


Question 2

Refer to the exhibit.

Switch-1 and Switch-2 ate ArubaOS-CX switches that implement VXLAN WITHOUT Ethernet VPN (EVPN). Switch-2 uses the same VNI-to-VLAN mappings as Switch-1. Is this how the specified servers communicate?

Solution: The first time that Server I communicates with Server 3, It sends an ARP request to resolve Server 3's MAC address.



Answer : B

The solution is incorrect because Switch-1 and Switch-2 implement VXLAN without EVPN, which means they do not have a control plane to exchange MAC addresses. Therefore, the first time that Server 1 communicates with Server 3, it sends an ARP request to resolve Server 3's IP address, not MAC address. The ARP request is encapsulated in a VXLAN header and sent to the VTEP of Switch-2, which decapsulates it and forwards it to Server 3.


Question 3

Does this correctly describe NetEdit's notification capabilities?

Solution: NetEdit notifies admins of errors using Its Internal email server.



Answer : B

NetEdit is a network management tool that allows you to configure, monitor, and troubleshoot ArubaOS-CX switches. NetEdit can send notifications of changes in network conditions to other services, such as email, using methods that define the service type and credentials. However, NetEdit does not use its internal email server to send notifications.NetEdit requires an external SMTP server to send email notifications, and the SMTP server address, port, username, and password must be configured in the email method1. Therefore, this does not correctly describe NetEdit's notification capabilities.


Question 4

Refer to the exhibit.

Switch-1, Switch-2, and the router run OSPF on LAG 100, which is a Layer 3 LAG. Does this correctly explain how to control how core-to-access traffic Is forwarded?

Solution: To reduce the amount of traffic sent over the ISL between Switch-1 and Switch-2. enable Equal Cost Multi Path (ECMP) on both Switch-1 and Switch-2.



Answer : B

To reduce the amount of traffic sent over the ISL between Switch-1 and Switch-2, enable Equal Cost Multi Path (ECMP) on both Switch-1 and Switch-2 is not a correct explanation of how to control how core-to-access traffic is forwarded. Switch-1, Switch-2, and the router run OSPF on LAG 100, which is a Layer 3 LAG. ECMP is a feature that allows a router to load balance traffic destined to some network that is reachable through multiple equal cost route nexthops. Enabling ECMP on Switch-1 and Switch-2 would not reduce the amount of traffic sent over the ISL, but rather increase it by sending traffic over both links instead of one.A better way to reduce the amount of traffic sent over the ISL would be to enable active forwarding on LAG 100 on both Switch-1 and Switch-2, which would make one link active and one link standby for each direction of traffic1.


Question 5

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 6

Does this correctly describe NetEdit's notification capabilities?

Solution: NetEdlt can send an error link to admins through ServlceNow.



Answer : A

NetEdit is a network management tool that allows you to configure, monitor, and troubleshoot ArubaOS-CX switches. NetEdit can send notifications of changes in network conditions to other services, such as ServiceNow, using methods that define the service type and credentials. ServiceNow is a cloud-based platform that provides IT service management and digital workflows.NetEdit can send an error link to admins through ServiceNow, which allows them to view the details of the error and take actions to resolve it1. Therefore, this correctly describes NetEdit's notification capabilities.


Question 7

Refer to the exhibit.

You need to set up an ArubaOS-CX switch to implement Virtual Extensible LAN (VXLAN) WITHOUT Ethernet VPN (EVPN). The exhibit Indicates which servers should be part of the same VXLANs and the desired VNls for the VXLANs. Assume that the network is already configured to permit each ArubaOS-CX switch to reach each other switch's loopback interface.

Is this part of the process for setting up VXLAN to meet the requirements?

Solution: On Switch-1, set 192.168.1.3 as a peer IP address in the VNI 5020 context.



Answer : A

On Switch-1, set 192.168.1.3 as a peer IP address in the VNI 5020 context is part of the process for setting up VXLAN to meet the requirements of enabling servers to be part of the same VXLANs and VNIs as shown in the exhibit. Switch-1, Switch-2, and Switch-3 are ArubaOS-CX switches that use VXLAN to provide Layer 2 extension over Layer 3 networks without EVPN. VXLAN is a feature that uses UDP encapsulation to tunnel Layer 2 frames over Layer 3 networks using VNIs. To set up VXLAN without EVPN on Switch-1, you need to do the following steps:

Configure loopback interfaces with IP addresses on each switch

Configure VLAN interfaces with IP addresses on each switch

Configure VXLAN interfaces with VNIs on each switch

Configure peer IP addresses for each VNI on each switch

Configure static routes or dynamic routing protocols to enable reachability between loopback interfaces On Switch-1, setting 192.168.1.3 as a peer IP address in the VNI 5020 context means that Switch-1 can send and receive VXLAN traffic for VNI 5020 to and from Switch-2, which has the loopback interface with IP address 192.168.1.3.
