Question 1

Does this correctly describe Network Analytics Engine (NAE) limitations on ArubaOS-CX switches?

Solution: Different switches have different limitations for the number of NAE scripts, monitors, and agents supported.



Answer : A

Different switches have different limitations for the number of NAE scripts, monitors, and agents supported is a correct description of Network Analytics Engine (NAE) limitations on ArubaOS-CX switches. NAE is a feature that provides automation and analytics for managing ArubaOS-CX switches. NAE scripts are scripts that run on switches and collect data from various sources. NAE monitors are rules that define conditions and actions for NAE agents. NAE agents are instances of NAE scripts and monitors that run on switches.Different switches have different limitations for the number of NAE scripts, monitors, and agents supported depending on their hardware resources1.


Question 2

Does this correctly describe routing information advertised by a VXLAN Tunnel Endpoint (VTEP) that uses EVPN?

Solution: MAC/IP advertisement routes advertise the MAC addresses that can be reached through the VTEP.



Answer : A

MAC/IP advertisement routes advertise the MAC addresses that can be reached through the VTEP is a correct description of routing information advertised by a VXLAN Tunnel Endpoint (VTEP) that uses EVPN. EVPN is a feature that provides control plane learning and signaling for VXLAN networks.MAC/IP advertisement routes are one of the types of routes that EVPN uses to advertise MAC and IP addresses of hosts connected to VTEPs2.


Question 3

Is this a use case for deploying Ethernet Ring Protection Switching (ERPS)?

Solution: connecting multiple data centers at Layer 2 while minimizing the number of dark fiber connections required



Answer : A

Connecting multiple data centers at Layer 2 while minimizing the number of dark fiber connections required is a use case for deploying Ethernet Ring Protection Switching (ERPS). ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies.ERPS can be used to connect multiple data centers at Layer 2 using fewer fiber connections than traditional mesh topologies1.


Question 4

You plan to use multi-protocol BGP to implement dynamic VRF route leaking on an ArubaOS-CX switch.

Is this a rule for the setup?

Solution: You cannot leak multicast routes.



Answer : A

You cannot leak multicast routes is a rule for the setup of multi-protocol BGP to implement dynamic VRF route leaking on an ArubaOS-CX switch.Multi-protocol BGP only supports unicast routes for route leaking, and multicast routes are not leaked between VRFs1.


Question 5

Is this something that NetEdit 2.0 does after it discovers a switch?

Solution: It collects Information about the switch hardware.



Answer : A

It collects information about the switch hardware is 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.After NetEdit 2.0 discovers a switch, it collects information about the switch hardware such as model number, serial number, MAC address, firmware version, etc1.


Question 6

Is this a use case for disabling split-recovery mode on ArubaOS-CX switches in a Virtual Switching Extension (VSX) fabric?

Solution: In situations in which the primary switch fails and then reboots, you want to make the primary switch take over again as the primary switch.



Answer : B

Virtual Switching Extension (VSX) is a high-availability technology that allows two ArubaOS-CX switches to operate as a single logical device. Split-recovery mode is a feature that prevents traffic loss when the Inter-Switch Link (ISL) goes out-of-sync and keepalive subsequently fails. When split-recovery mode is enabled, the secondary VSX member disables its downstream links until it synchronizes with the primary member.When split-recovery mode is disabled, the secondary VSX member keeps its downstream links up even when it is out-of-sync with the primary member1. Disabling split-recovery mode does not affect how the primary switch takes over again as the primary switch after a failure and reboot. The primary switch always takes over as the primary switch when it comes back online, regardless of the split-recovery mode setting. Therefore, this is not a use case for disabling split-recovery mode on ArubaOS-CX switches in a VSX fabric.


Question 7

AtubaOS-CX switches are acting as Virtual Extensible LAN (VXLAN) Tunnel Endpoints (VTEPs) WITHOUT Ethernet VPN (EVPN).

Does this correctly describe how the VTEPs handle VXLAN traffic forwarding?

Solution: VTEPs that use headend replication forward broadcasts as unicast packets to each VTEP in the same VNI.



Answer : A

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.
