HPE2-W09 HP Aruba Data Center Network Specialist Exam Free Practice Exam Questions (2025 Updated)

ARP and ND Suppression are features of ArubaOS-CX that reduce the broadcast traffic on EVPN VXLAN networks1. ARP and ND Suppression enable the switch to reply to ARP and ND requests with information present in the local ARP and neighbor cache, instead of flooding them to all VTEPs1. This reduces the bandwidth consumption and improves the network performance1. ARP-Suppression and ND-Suppression can be enabled or disabled independently1. They do not have to be enabled together1. Therefore, this statement about ARP and ND Suppression is false, and the correct answer is no. For more information on ARP and ND Suppression, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet3 and the EVPN VXLAN Guide for your switch model1.

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.

VSX features a dual control plane while VSF features a single control plane. VSX and VSF are both high availability solutions that provide redundancy and load balancing across a pair of switches1. However, VSX features a dual control plane, which means that each switch has its own independent configuration and state information1. VSF features a single control plane, which means that one switch acts as the commander and synchronizes the configuration and state information to the other switch1. The statement is true because it correctly describes the difference between VSX and VSF control planes.

NetEdit is a network management tool that allows you to configure, monitor, and troubleshoot ArubaOS-CX switches. NetEdit can send notifications of changes in network conditions to other services, such as ServiceNow, using methods that define the service type and credentials. ServiceNow is a cloud-based platform that provides IT service management and digital workflows. NetEdit can send an error link to admins through ServiceNow, which allows them to view the details of the error and take actions to resolve it1. Therefore, this correctly describes NetEdit’s notification capabilities.

Aruba Fabric Composer (AFC) with HPE StoreServ Management Console (SSMC) integration is possible. AFC is a software-defined networking solution that simplifies the management and orchestration of data center networks1. It can integrate with various data center software, such as VMware, Ansible, and Kubernetes1. SSMC is a web-based management tool that provides a unified interface for managing HPE 3PAR StoreServ storage systems2. AFC can integrate with SSMC to discover and visualize the storage network infrastructure and provide end-to-end visibility and troubleshooting1.

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.

 Implementing Virtual Switching Extension (VSX) on pairs of ERPS switches at the same site is part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) solution. VSX allows two switches to act as a single logical device and provide active-active forwarding across both switches. This way, traffic can be load balanced across all links in the ERPS ring without creating loops1.

Split-recovery mode is a feature of ArubaOS-CX that prevents traffic loss when the ISL goes out-of-sync and keepalive subsequently fails12. This can happen if the ISL is restored after a failure but the VSX nodes are not synchronized. Split-recovery mode enables the secondary switch to restore its VSX LAGs after 10 keepalive packets are missed, approximately 10 seconds after keepalive goes down2. This avoids a split brain situation where both switches act as primary and forward traffic independently, causing loops and duplicate packets1. Therefore, disabling split-recovery mode is not a use case for preventing split brain situations, and the correct answer is yes. For more information on split-recovery mode and VSX, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet3 and the Virtual Switching Extension (VSX) Guide for your switch model2.

VXLAN is a feature of ArubaOS-CX that provides layer 2 connectivity between networks across an IP network1. VXLAN uses a 24-bit identifier called VXLAN Network Identifier (VNI) to segment the layer 2 domain1. VXLAN also uses a tunnel endpoint (VTEP) to encapsulate and decapsulate VXLAN packets1. A VXLAN interface is a logical interface that represents a VNI and is associated with a source IP address and a VRF1. To set up VXLAN without EVPN, you need to create VXLAN interfaces on each switch and configure static VTEP peers1. Based on the exhibit, Switch-1 needs to create two VXLAN interfaces, one with ID 5010 and one with ID 5020, to match the VNIs of the servers connected to it. However, you cannot add multiple VNIs to the same VXLAN interface1. Each VNI must have its own VXLAN interface with a unique source IP address and VRF1. Therefore, this is not part of the process for setting up VXLAN to meet the requirements, and the correct answer is no. For more information on VXLAN and EVPN, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet2 and the EVPN VXLAN Guide for your switch model1.

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

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.

The status is Idle, which means that the ring is up and fully connected with the RPL port blocked is not what the specified status means for Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Idle is one of the possible statuses for an ERPS ring instance, but it indicates that the ring is not operational and no port is blocked. This can happen when the ring is not configured properly or when there is a miscommunication between the nodes1.

Deploy Aruba CX 83xx switches as data center spine switches is a best practice when positioning ArubaOS-CX switches in data center networks. The Aruba CX 83xx switches are designed for data center spine or core roles, and they provide high performance, scalability, and resiliency. They can support various data center network architectures such as leaf-spine, three-tier, or collapsed core1.

 Uploading firmware images to the NetEdit firmware repository is part of the process for using NetEdit to update firmware on ArubaOS-CX switches1. NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface1. It also provides a firmware repository where you can store firmware images for different switch models and versions1. You can use NetEdit to upload firmware images to the repository and then deploy them to the switches1.

 ArubaOS-CX switches are designed for enterprise campus, aggregation, and data center networking use cases1. ArubaOS-CX switches support a leaf-spine topology, which is a two-layer network architecture that provides high performance, scalability, and reliability for data center networks2. Aruba CX 8325 switches are compact 1U switches that offer high density and high speed connectivity for both leaf and spine switches3. Aruba CX 8325 switches can support up to 32 ports of 100GbE or 48 ports of 25GbE and 8 ports of 100GbE3. For a data center that requires 64 leaf switches, Aruba CX 8325 switches can be a good choice for both the leaf and spine switches, as they can provide enough bandwidth and port density for the network traffic3. Therefore, this is a correct positioning of ArubaOS-CX switches in the data center, and the correct answer is yes. For more information on ArubaOS-CX switches and data center solutions, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet and the Aruba CX Switch Series datasheets3 .

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. VTEPs can use different methods to handle broadcast, unknown unicast, and multicast (BUM) traffic within a VNI. One of these methods is headend replication, which means that the VTEP that receives a BUM packet replicates it and sends it as a unicast to each remote VTEP in the same VNI1. This method does not require 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.

Implement Virtual Switching Extension (VSX) on pairs of ERPS switches at the same site. Then combine multiple links between two data centers into VSX LAGs (MC-LAGs) is not part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) ring. ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. VSX LAGs or MC-LAGs are LAGs that span across two VSX nodes and provide load balancing and resiliency. However, VSX LAGs or MC-LAGs are not supported by ERPS because they can create loops in the ring topology. A better way to load share traffic across the links in an ERPS ring would be to use link aggregation groups (LAGs) between two nodes in a ring as long as they are not multi-chassis LAGs (MC-LAGs)1.
