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.

Creating two configuration plans, one with the standard config and one with the device-specific settings, is not what you should do. NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface1. It also provides a plan feature that lets you create containers to group devices and execute operations on them, such as deploying, committing, or rolling back device configuration or firmware1. However, you do not need to create two configuration plans for your scenario. You can create one configuration plan with the standard config and use variables to define the device-specific settings1. Variables are placeholders that can be replaced with different values for different devices1. This way, you can deploy a standard config with device-specific settings using one configuration plan1.

Agents do not collect data every minute and send the data to a centralized SNMP server in SNMP traps. NAE is a feature that provides network operators with distributed analytics for faster troubleshooting and resolution of network-impacting issues1. Agents are scripts that run on ArubaOS-CX switches and collect data from various sources, such as CLI commands, REST APIs, or syslog messages1. Agents can also define conditions and actions based on the collected data1. Agents do not send the data to a centralized SNMP server, but store it locally on the switch1. Agents can also send alerts to external systems, such as email servers or syslog servers, but not in SNMP traps1. The statement is false because it incorrectly describes how NAE agents work.

Headend replication is a method of handling BUM traffic in VXLAN networks without EVPN, where the ingress VTEP replicates every BUM packet and sends them as a separate unicast to the remote egress VTEPs in the same VNI1. This avoids the need for multicast routing in the underlay network, but it can increase the load on the ingress VTEP. Therefore, this correctly describes how the VTEPs handle VXLAN traffic forwarding without EVPN.

VXLAN is a tunneling protocol that encapsulates layer 2 traffic over an IP network using VXLAN Network Identifiers (VNIs) to identify different layer 2 segments. VXLAN Tunnel Endpoints (VTEPs) are devices that perform the encapsulation and decapsulation of VXLAN packets. According to the exhibit, Switch-1 and Switch-2 are VTEPs that use VNI 10010 to map VLAN 10 traffic. Therefore, when Switch-1 receives a frame with destination MAC address 00:50:56:00:00:03 and VLAN 10 tag on interface 1/1/1, it should encapsulate the frame with a VXLAN header that contains VNI 10010 and send it as a unicast packet to Switch-2's loopback address (10.1.1.2) over the IP network1. Switch-1 should not switch the frame out interface 1/1/2 without VXLAN, as this would violate the VNI mapping and cause layer 2 loops. Therefore, this is not how the switch handles the traffic.

Virtual Switching Extension (VSX) is a high-availability technology that allows two ArubaOS-CX switches to operate as a single logical device. VSX Inter-Switch Link (ISL) is a link between the two VSX switches that is used for both data plane and control plane traffic. It is recommended that the ISL link is a link aggregation with multiple 40GbE links or multiple 100GbE links to provide redundancy and bandwidth1. Therefore, this is a valid guideline for establishing a VSX ISL between two ArubaOSCX switches.

Virtual Switching Extension (VSX) is a high-availability technology that allows two ArubaOS-CX switches to operate as a single logical device. VSX Inter-Switch Link (ISL) is a link between the two VSX switches that is used for both data plane and control plane traffic. It is not recommended to reserve the ISL for control plane traffic only, as this would limit the benefits of VSX and create suboptimal traffic forwarding1. Therefore, this is not a valid guideline for establishing a VSX ISL between two ArubaOS-CX switches.

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.

ArubaOS-CX is a modern operating system for Aruba switches that provides automation, programmability, and analytics capabilities. The ArubaOS-CX Network Analytics Engine (NAE) is a built-in analytics framework for network assurance and remediation, that allows monitoring, troubleshooting, and proactive network management using scripts and agents1. The NAE does not help admins to manage multiple ArubaOS-CX switches together using familiar CLI commands. That is the function of the ArubaOS-CX Fabric Composer (AFC), which is a software-defined orchestration tool that simplifies data center fabric management. Therefore, this does not correctly describe the ArubaOS-CX architecture.
