Question 1

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 can only leak routes between up to three VRFs.



Answer : B

You can only leak routes between up to three VRFs is not a rule for the setup of multi-protocol BGP to implement dynamic VRF route leaking on an ArubaOS-CX switch. There is no limit on the number of VRFs that can participate in route leaking using multi-protocol BGP.You can configure multiple import and export route targets for each VRF and leak routes between any VRFs that have matching route targets1.


Question 2

You enter this command on an ArubaOS-CX switch:

Switch# show erps status ring 1

Is this what the specified status means?

Solution: The status is Pending, which means that the ring is configured but not enabled administratively



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 is 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


Question 3

Is this a way that a data center technology can help meet requirements for multi-tenancy?

Solution: Virtual Extensible LAN (VXLAN) enables multiple isolated Layer 3 domains, each with its own routing table, to share a physical network.



Answer : B

Virtual Extensible LAN (VXLAN) enables multiple isolated Layer 3 domains, each with its own routing table, to share a physical network is not a way that a data center technology can help meet requirements for multi-tenancy. Multi-tenancy is the ability to provide logical separation and isolation of network resources for different tenants or customers on a shared physical infrastructure. VXLAN is a feature that provides Layer 2 extension over Layer 3 networks using UDP encapsulation.VXLAN does not enable multiple isolated Layer 3 domains, but rather multiple isolated Layer 2 domains, each with its own VNI1.


Question 4

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 5

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

Solution: It enables the switch REST API Interface, if disabled.



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.


Question 6

An ArubaOS-CX is \ssmq DCBX on Interface 1/1/1. You enter this command:

show dcbx interface 1/1/1

Is this where you can see whether the connected converged network adapter (CNA) has accepted the application priorities advertised with DCBX?

Solution: in the Enhanced Transmission Selection (ETS) Local advertisement section



Answer : B

In the Enhanced Transmission Selection (ETS) Local advertisement section is not where you can see whether the connected converged network adapter (CNA) has accepted the application priorities advertised with DCBX on an ArubaOS-CX switch interface. The ETS Local advertisement section shows the priority groups and bandwidth allocation that the switch advertises to the CNA, but it does not show whether the CNA has accepted them or not.To see whether the CNA has accepted the application priorities advertised with DCBX, you need to look at the Application Priority Local advertisement section, which shows the application protocol identifier (APPID) and priority values that the switch advertises to the CNA, and compare them with the Application Priority Remote advertisement section, which shows the APPID and priority values that the CNA advertises to the switch1.


Question 7

Refer to the exhibits.

Is this how the switch handles the traffic?

Solution: 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 VXIAN and sends it to 192.168.1.2. but not 192.168.1.3.



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.
