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.

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 replicates the broadcast, encapsulates each broadcast with VXLAN, and sends the VXLAN traffic to 192.168.1.2 and 192.168.1.3 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 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. Switch-1 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 respectively.

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 192.168.1.3, which is Switch-2'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 respectively.

Combine multiple links between two data centers into link aggregations (but not multi-chassis ones) is part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) ring. ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies. ERPS can support link aggregation groups (LAGs) between two nodes in a ring as long as they are not multi-chassis LAGs (MC-LAGs). MC-LAGs are not supported by ERPS because they can create loops in the ring topology.

The Virtual Switching Extension (VSX) fabric is a high availability solution that provides industry-leading performance and simplicity for campus and data center networks1. When the ISL goes down, and after a few seconds, the keepalive link goes down too, the VSX fabric reacts differently depending on the split-recovery mode setting.If the split-recovery mode is enabled, the secondary switch shuts down all its SVIs and waits for the ISL to come back up2.If the split-recovery mode is disabled, both switches keep their SVIs up and continue to forward traffic2. Therefore, this does not correctly describe how the VSX fabric reacts to various component failure scenarios. Reference: https://www.arubanetworks.com/assets/tg/TB_VSX.pdf
