HP Aruba Data Center Network Specialist HPE2-W09 Exam Practice Test

Answer : A

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.

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

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.

Answer : B

Based on the exhibits, Switch-1 has a trunk port on 1/1/1 that allows VLANs 10 and 20. Switch-2 has an access port on 1/1/2 that belongs to VLAN 10. Switch-3 has an access port on 1/1/3 that belongs to VLAN 20. If a broadcast arrives with a VLAN 10 tag on 1/1/1 on Switch-1, Switch-1 does not drop the frame. Instead, Switch-1 forwards the frame to all ports that belong to VLAN 10, which includes the trunk port 1/1/2 and the access port 1/1/4. Switch-2 receives the frame on its access port 1/1/2 and forwards it to all ports in VLAN 10, which includes the access port 1/1/5. Switch-3 does not receive the frame because it is not in VLAN 10. Therefore, this is not how the switch handles the traffic, and the correct answer is no.

Answer : B

To help the switch to look inside tunneled traffic and apply different quality of service (QoS) settings to different types of traffic is not a use case for implementing Enhanced Transmission Selection (ETS) on an ArubaOS-CX switch. ETS is a feature that provides bandwidth allocation and priority assignment for different traffic classes based on IEEE 802.1Qaz standard. ETS does not help the switch to look inside tunneled traffic, but rather relies on the priority values in the outer header of the tunneled traffic to apply QoS settings. A better way to help the switch to look inside tunneled traffic and apply different QoS settings to different types of traffic would be to use deep packet inspection (DPI) or application visibility and control (AVC) features.

Answer : A

VSX permits admins to select which features to synchronize between members while VSF requires manual configuration of identical features on each member of the VSF fabric is a way that Virtual Switching Extension (VSX) differs from Virtual Switching Framework (VSF). VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. VSF is a feature that provides active-standby forwarding and redundancy for legacy campus switches.VSX allows admins to select which features to synchronize between members using an opt-in model, while VSF requires manual configuration of identical features on each member using a commander-member model1.

Answer : B

A broadcast arrives in VLAN 10 on Switch-1. Switch 1 forwards the frame on all interfaces assigned to VLAN 10, except the incoming interface. It encapsulates the broadcast with VXLAN and sends it to 192.168.1.3, but not 192.168.1.2 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 192.168.1.3, which is Switch-2'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 respectively.
