VSX permits admins to select which features to synchronize between members while VSF requires manual configuration of identical features on each member of the VSF fabric is a way that Virtual Switching Extension (VSX) differs from Virtual Switching Framework (VSF). VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. VSF is a feature that provides active-standby forwarding and redundancy for legacy campus switches. VSX allows admins to select which features to synchronize between members using an opt-in model, while VSF requires manual configuration of identical features on each member using a commander-member model1.

Virtual Extensible LAN (VXLAN) enables multiple isolated Layer 3 domains, each with its own routing table, to share a physical network is not a way that a data center technology can help meet requirements for multi-tenancy. Multi-tenancy is the ability to provide logical separation and isolation of network resources for different tenants or customers on a shared physical infrastructure. VXLAN is a feature that provides Layer 2 extension over Layer 3 networks using UDP encapsulation. VXLAN does not enable multiple isolated Layer 3 domains, but rather multiple isolated Layer 2 domains, each with its own VNI1.

Virtual Extensible LAN (VXLAN) provides millions of IDs to scale for the needs of a multi-tenant environment is a way that a data center technology can help meet requirements for multi-tenancy. Multi-tenancy is the ability to provide logical separation and isolation of network resources for different tenants or customers on a shared physical infrastructure. VXLAN is a feature that provides Layer 2 extension over Layer

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.

To reduce the amount of traffic sent over the ISL between Switch-1 and Switch-2, enable active forwarding on LAG 100 on both Switch-1 and Switch-2 is 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. Active forwarding is a feature that allows a switch to select one link as active and one link as standby for each direction of traffic in a LAG. Enabling active forwarding on LAG 100 on both Switch-1 and Switch-2 would reduce the amount of traffic sent over the ISL by sending traffic over only one link instead of both1.

Different switches have different limitations for the number of NAE scripts, monitors, and agents supported is a correct description of Network Analytics Engine (NAE) limitations on ArubaOS-CX switches. NAE is a feature that provides automation and analytics for managing ArubaOS-CX switches. NAE scripts are scripts that run on switches and collect data from various sources. NAE monitors are rules that define conditions and actions for NAE agents. NAE agents are instances of NAE scripts and monitors that run on switches. Different switches have different limitations for the number of NAE scripts, monitors, and agents supported depending on their hardware resources1.

Aruba Fabric Composer (AFC) with Nutanix Hypervisor (AHV) integration is possible. AFC is a tool that provides automation and orchestration for managing data center networks composed of ArubaOS-CX switches. AFC can integrate with various data center software such as VMware vSphere, Nutanix AHV, Microsoft Hyper-V, etc. AFC can discover, monitor, and configure Nutanix AHV clusters and hosts using REST APIs1.

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.

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.
