VSX is not recommended for the access layer of data centers and campuses while VSF is recommended for the core. VSX and VSF are both high availability solutions that provide redundancy and load balancing across a pair of switches1. However, VSX is recommended for the core and aggregation layers of data centers and campuses, while VSF is recommended for the access layer of campuses1. The statement is false because it reverses the recommended roles of VSX and VSF.

ERPS is a feature of ArubaOS-CX that prevents loops at layer 2 on ring networks1. ERPS uses a protocol called Ring Auto Protection Switching (RAPS) to detect link failures and perform fast traffic switchover1. ERPS has two timers that control the protection switching mechanism: guard timer and hold off timer1. The guard timer prevents false switching caused by delayed or lost RAPS PDUs1. The guard interval is set in units of 10 ms and should exceed the maximum expected delay for forwarding a frame around the complete ring1. This ensures that all switches on the ring receive the RAPS PDUs before the guard timer expires1. Therefore, this is a guideline for configuring timers for ERPS, and the correct answer is yes. For more information on ERPS and timers, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet2 and the ERPS Guide for your switch model1.

Work with the server admins to assign a consistent VLAN for VMs 1 and 4. Assign interface 1/1/2 on Switch-1 to the same VLAN is part of a valid configuration to meet the requirements for providing VXLAN services for several VMs and servers using ArubaOS-CX switches. VMs 1 and 4 belong to the same VXLAN segment (VNI 5010), so they should be assigned to the same VLAN on their respective hypervisors. Interface 1/1/2 on Switch-1 should also be assigned to the same VLAN as VMs 1 and 4, so that Switch-1 can act as a VTEP for them1.

Inside a configuration plan, right-click any device-specific parameters and modify the parameter per-device is 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 allows you to edit any parameter value for individual devices within a configuration plan without affecting other devices or creating separate plans1.

The show dcbx interface command shows the current DCBx status and the configuration of PFC, ETS, and application priority applied on the interface and the status of the TLVs received from the peer1. The Application Priority Map section shows the protocol, port/type and priority for both local and remote advertisements. Therefore, this is where you can see whether the connected converged network adapter (CNA) has accepted the application priorities advertised with DCBX.

Agents write data to the switch’s current state database is a correct description of how Network Analytics Engine (NAE) agents work. NAE agents are scripts that run on ArubaOS-CX switches and collect data from various sources such as CLI commands, REST APIs, SNMP queries, etc. The agents write the collected data to the switch’s current state database (CSDB), which stores information about the switch’s configuration, status, and performance1.

Use a firmware update plan to manage both updating the Image on selected devices and reboot is part of the process for using NetEdit to update firmware on ArubaOS-CX switches. NetEdit is a tool that provides automation and analytics for managing ArubaOS-CX switches. A firmware update plan is a type of plan that allows you to update the firmware image on one or more switches and reboot them as needed1.

The ISL and keepalive goes down, and after a few seconds, the keepalive link restores. Switch-1 and Switch-2 remains up. The Split-recovery mode is enabled. In this case the secondary switch shutdowns SVIs when keepalive is restored is a correct description of how the Virtual Switching Extension (VSX) fabric reacts to various component failure scenarios. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. The ISL is the inter-switch link that connects two VSX nodes and carries data traffic. The keepalive link is a separate link that carries control traffic between two VSX nodes. The split-recovery mode is a feature that prevents split-brain scenarios when both VSX nodes lose connectivity with each other but remain up. When the ISL and keepalive goes down, both VSX nodes continue to forward traffic independently. When the keepalive link restores, the secondary switch detects that it has lost synchronization with the primary switch and shuts down its SVIs to prevent traffic loops1.

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.

IMET routes advertise the MAC addresses that the VTEP has learned locally in a VXLAN is not a correct description of routing information advertised by a VXLAN Tunnel Endpoint (VTEP) that uses EVPN. IMET routes are one of the types of routes that EVPN uses to advertise multicast information for VXLAN networks. IMET routes advertise the IP addresses of VTEPs that can join multicast groups for VXLAN segments2.
