Question 1

Refer to the exhibit.

You are adding a VLAN 30, subnet 10.0.30.0/24 to the network shown in the exhibit. (This network is simplified to just the relevant switches for this item.) This subnet belongs in VRF A, and you have added a Layer 3 VLAN 30 interface attached to this VRF on Switch-1. You want to make the services in this VLAN available to devices in 10.1.20.0/24 in VRF B.

Is this part of a valid setup for meeting these requirements?

Solution: Add a route with this command: ip route 10.1.20.0/24 vlan20 vrf A



Answer : B

Adding a route with this command: ip route 10.1.20.0/24 vlan20 vrf A is not part of a valid setup for meeting these requirements. This command would add a static route for 10.1.20.0/24 in VRF A, but it would not be able to reach VLAN 20 on Switch-2 because Switch-2 does not have a VLAN interface for VLAN 20 in VRF A.To make the services in VLAN 30 available to devices in 10.1.20.0/24 in VRF B, you need to use inter-VRF routing or route leaking between VRF A and VRF B on Switch-11.


Question 2

The architect designs a spine and leaf network for a single data center that will use multiple leaf switches as Virtual Tunnel End Points (VTEP). The architect needs to select the type of Integrated Routing & Bridging (IRB) for the solution.

Is this statement about the IRB type true?

Solution: Asymmetric IRB requires a third L3 VNI to route packets between ingress and egress VTEPs.



Answer : A

Asymmetric IRB requires a third L3 VNI to route packets between ingress and egress VTEPs is a true statement about the IRB type for a spine and leaf network for a single data center that will use multiple leaf switches as Virtual Tunnel End Points (VTEP). Asymmetric IRB is a method of routing traffic between different VXLAN segments using a centralized gateway.In this method, ingress VTEPs route the traffic to the gateway VTEP using a Layer 3 VNI, and egress VTEPs route the traffic to the destination networks using a Layer 2 VNI1. The Layer 3 VNI acts as a transit VNI for inter-VXLAN routing.


Question 3

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 Protection, which means that the ring is up and fully connected with the RPL port blocked.



Answer : A

The status is Protection, which means that the ring is up and fully connected with the RPL port blocked is what the specified status means for Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Protection is one of the possible statuses for an ERPS ring instance, and it indicates that the ring is operating normally with one port blocked to prevent loops.The RPL port is the port that connects to the RPL node, which is responsible for blocking and unblocking traffic on the ring2


Question 4

Your customer is using Nutanix AHV and they need a network orchestration tool to simplify network provisioning. Is this operation supported when Aruba Fabric Composer (AFC) is integrated with Nutanix?

Solution: Automated configuration of Layer 3 MP-BGP protocol on leaf switches



Answer : B

Automated configuration of Layer 3 MP-BGP protocol on leaf switches is not an operation supported when Aruba Fabric Composer (AFC) is integrated with Nutanix. AFC is a tool that provides automation and orchestration for managing data center networks composed of ArubaOS-CX switches. AFC can integrate with various data center software such as VMware vSphere, Nutanix AHV, Microsoft Hyper-V, etc. AFC can discover, monitor, and configure Nutanix AHV clusters and hosts using REST APIs. However, AFC does not support the configuration of Layer 3 MP-BGP protocol on leaf switches, which is required for EVPN VXLAN networks.AFC only supports the configuration of Layer 2 VXLAN networks without EVPN1.


Question 5

Switch-1 and Switch-2 are AruDaOS-CX switches, which are part of a Virtual Switching Extension (VSX) fabric. Switch-2 is the primary member. Switch-2 experiences a power failure while Switch-1 remains up. Switch-2's power recovers, and Switch-2 reboots.

Is this one of the things that happens when Switch-2 finishes booting?

Solution: Switch-2 wails a period called the link-up delay before it enables Switched Virtual Interfaces (SVls) on its VSX LAGs.



Answer : A

Switch-2 waits a period called the link-up delay before it enables Switched Virtual Interfaces (SVIs) on its VSX LAGs is a true statement about what happens when Switch-2 experiences a power failure while Switch-1 remains up and then recovers. Switch-1 and Switch-2 are ArubaOS-CX switches, which are part of a Virtual Switching Extension (VSX) fabric. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. The link-up delay timer defines how long a VSX node waits before advertising link state changes to its peer node.This allows the node to synchronize its MAC forwarding, ARP, and routing tables with its peer node before sending or receiving traffic on the newly activated link1.


Question 6

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 7

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.
