Correct Answer: A

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 ArubaOS-CX switches.

Correct Answer: A

Aruba CX 8325 switches are an appropriate choice for leaf switches in a leaf- spine topology that uses Virtual Extensible LAN (VXLAN) with Ethernet VPN (EVPN) is a correct positioning of ArubaOS-CX switches in the data center. The Aruba CX 8325 switches are designed for data center spine or core roles, but they can also be used as leaf switches in a VXLAN with EVPN scenario. They support advanced features such as VSX, EVPN, and PFC that enable high performance, scalability, and resiliency for data center networks1.

Correct Answer: B

It enables the switch REST API interface, if disabled is not something that NetEdit 2.0 does after it discovers a switch. NetEdit 2.0 is a tool that provides configuration management and validation for ArubaOS-CX and ArubaOS-Switch devices. NetEdit 2.0 can discover switches using various methods such as IP range scan, LLDP scan, CSV import, etc. However, NetEdit 2.0 cannot discover or communicate with switches that have their REST API interface disabled because NetEdit

2.0 relies on REST API calls to interact with switches1.

Correct Answer: B

The status is Pending, which means that the ring is configured but not operational. The ring instance may be in one of the following states: Idle, Initializing, Pending, or Failed1. The Pending state indicates that the ring instance 1s waiting for a trigger event to become operational, such as a link failure or a manual command1. The status does not depend on whether the ring is enabled administratively or not. https://www.arubanetworks.com/techdocs/AOS-CX/10.08/HTML/high_availability/Content/Chp_ERPS/ERPS_cmds/sho-erp-sta4.htm

Correct Answer: B

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.
