Place all three VRFs in the same OSPF process on Switch-1 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 not work because OSPF does not support multiple VRFs in the same process on ArubaOS-CX switches. Each VRF must have its own OSPF process with a unique process ID1.

A schedule profile is a feature of ArubaOS-CX that determines the order and service of queues for transmission123. A schedule profile must be configured on every interface at all times23. The switch supports three scheduling algorithms: Guaranteed Minimum Bandwidth (GMB), Strict, and Strict EQS23. Strict scheduling gives absolute priority to a queue over other queues, regardless of the bandwidth allocation23. If the profile mixes strict priority scheduling with another scheduling algorithm, the strict priority queue must be the highest numbered queue23. Therefore, this is a rule for configuring schedule profiles on an ArubaOS-CX switch, and the correct answer is yes. For more information on schedule profiles and QoS, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet1 and the QoS Guide for your switch model23.

Deploy Aruba CX 6300 switches as data center spine switches is not a best practice when positioning ArubaOS-CX switches in data center networks. The Aruba CX 6300 switches are designed for data center leaf roles, and they provide high density, low latency, and advanced features such as VSX and EVPN. The Aruba CX 83xx switches are more suitable for data center spine roles, and they provide high performance, scalability, and resiliency1.

Extending Layer 2 communications between data centers that connect over Layer 3 MPLS links is not a use case for deploying Ethernet Ring Protection Switching (ERPS). ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies. ERPS does not support extending Layer 2 communications over Layer 3 networks such as MPLS1.

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.

ARP and ND Suppression are features of ArubaOS-CX that reduce the broadcast traffic on EVPN VXLAN networks1. ARP and ND Suppression enable the switch to reply to ARP and ND requests with information present in the local ARP and neighbor cache, instead of flooding them to all VTEPs1. This reduces the bandwidth consumption and improves the network performance1. ARP-Suppression and ND-Suppression can be enabled or disabled independently1. They do not have to be enabled together1. Therefore, this statement about ARP and ND Suppression is false, and the correct answer is no. For more information on ARP and ND Suppression, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet3 and the EVPN VXLAN Guide for your switch model1.

A frame with destination MAC address, 00:50:56:15:16:28, arrives with a VLAN 10 tag on 1/1/1 on Switch-1. Switch-1 encapsulates the frame with VXLAN and an IP header destined to 192.168.1.2 is 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 MAC and IP addresses of hosts connected to VTEPs. Switch-1 receives a frame with destination MAC address, 00:50:56:15:16:28, which belongs to VM-2 on Switch-3. Switch-1 learns from EVPN that VM-2 is reachable through VTEP 192.168.1.2, which is Switch-3’s loopback interface. Switch-1 encapsulates the frame with VXLAN and an IP header destined to 192.168.1.2 and sends it over the underlay network1.

Multi-tenancy is the ability to provide network services to multiple independent customers or tenants on a shared physical infrastructure. One of the challenges of multi-tenancy is to ensure isolation and security between different tenants, while also providing scalability and efficiency. Virtual Routing and Forwarding (VRF) is a data center technology that can help meet these requirements by enabling multiple isolated Layer 3 domains, each with its own routing table, to share a physical network1. VRF allows different tenants to use overlapping IP addresses and routing protocols without interfering with each other. Therefore, this is a valid way that a data center technology can help meet requirements for multi-tenancy.
