HP Aruba Data Center Network Specialist HPE2-W09 Exam Questions

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

Deploying Aruba CX 8400 switches as core switches for very large three-tier data center networks is how you should position switches in the ArubaOS-CX portfolio for data center networks.ArubaOS-CX is an operating system that provides advanced features and automation capabilities for data center networks1.It runs on various switch models that are designed for different roles and scenarios in the data center1.Aruba CX 8400 switches are modular switches that offer high performance, scalability, and reliability for the core layer of very large three-tier data center networks1. The statement is true because it correctly describes how to position Aruba CX 8400 switches in the ArubaOS-CX portfolio for data center networks.

Answer : B

To reduce the amount of traffic sent over the ISL between Switch-1 and Switch-2, enable Equal Cost Multi Path (ECMP) on both Switch-1 and Switch-2 is not a correct explanation of how to control how core-to-access traffic is forwarded. Switch-1, Switch-2, and the router run OSPF on LAG 100, which is a Layer 3 LAG. ECMP is a feature that allows a router to load balance traffic destined to some network that is reachable through multiple equal cost route nexthops. Enabling ECMP on Switch-1 and Switch-2 would not reduce the amount of traffic sent over the ISL, but rather increase it by sending traffic over both links instead of one.A better way to reduce the amount of traffic sent over the ISL would be to enable active forwarding on LAG 100 on both Switch-1 and Switch-2, which would make one link active and one link standby for each direction of traffic1.

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.

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.

Answer : B

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 email, using methods that define the service type and credentials. However, NetEdit does not use its internal email server to send notifications.NetEdit requires an external SMTP server to send email notifications, and the SMTP server address, port, username, and password must be configured in the email method1. Therefore, this does not correctly describe NetEdit's notification capabilities.

Answer : A

Work with the server admins to assign a consistent VLAN for VMs 1 and 4. Assign interface 1/1/2 on Switch-1 to the same VLAN is part of a valid configuration to meet the requirements for providing VXLAN services for several VMs and servers using ArubaOS-CX switches. VMs 1 and 4 belong to the same VXLAN segment (VNI 5010), so they should be assigned to the same VLAN on their respective hypervisors.Interface 1/1/2 on Switch-1 should also be assigned to the same VLAN as VMs 1 and 4, so that Switch-1 can act as a VTEP for them1.
