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.

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.

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. https://networklessons.com/cisco/ccnp-encor-350-401/introduction-to-virtual-extensible-lan-vxlan

The solution is correct because using the same speed on every link in the ISL is a guideline for establishing a VSX ISL between two ArubaOS-CX switches. Using the same speed on every link in the ISL ensures consistent performance and avoids potential issues with link aggregation. Therefore, using the same speed on every link in the ISL is a good practice for establishing a VSX ISL.

The solution is incorrect because enabling the REST interface in read-only mode is not a minimum requirement for setting up communications between the switch and NetEdit. NetEdit uses the REST interface to configure the switch, so it needs write access as well as read access. Therefore, enabling the REST interface in read-write mode is a minimum requirement for setting up communications between the switch and NetEdit.
