HPE2-W09 Online Practice Questions and Answers

Correct Answer: B

Virtual Switching Extension (VSX) is a high-availability technology that allows two ArubaOS-CX switches to operate as a single logical device. VSX Inter-Switch Link (ISL) is a link between the two VSX switches that is used for both data plane and control plane traffic. It is not recommended to reserve the ISL for control plane traffic only, as this would limit the benefits of VSX and create suboptimal traffic forwarding1. Therefore, this is not a valid guideline for establishing a VSX ISL between two ArubaOS-CX switches.

Correct Answer: B

Attach VNIs 5010 and 5020 to interface 1/1/3 on Switch-2 is not part of a valid configuration to meet the requirements for providing VXLAN services for several VMs and servers using ArubaOS-CX switches. VNIs are virtual network identifiers that are used to identify VXLAN segments. A VNI can only be attached to a VLAN interface, not a physical interface, on an ArubaOS-CX switch1.

Correct 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.

Correct Answer: A

Data center networks are typically less oversubscribed than campus networks is a difference between a typical data center network's requirements and a typical campus network's requirements. Oversubscription is the ratio of potential maximum demand to available capacity on a network link or device. Data center networks typically have higher bandwidth and lower latency requirements than campus networks, so they need to minimize oversubscription as much as possible1.

Correct Answer: A

Virtual Switching Extension (VSX) is a high-availability technology that allows two ArubaOS-CX switches to operate as a single logical device. VSX Inter-Switch Link (ISL) is a link between the two VSX switches that is used for both data plane and control plane traffic. It is recommended that the ISL link is a link aggregation with multiple 40GbE links or multiple 100GbE links to provide redundancy and bandwidth1. Therefore, this is a valid guideline for establishing a VSX ISL between two ArubaOS-CX switches.

Correct 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.

Correct 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.

Correct Answer: B

Creating two configuration plans, one with the standard config and one with the device-specific settings, is not what you should do. NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface1. It also provides a plan feature that lets you create containers to group devices and execute operations on them, such as deploying, committing, or rolling back device configuration or firmware1. However, you do not need to create two configuration plans for your scenario. You can create one configuration plan with the standard config and use variables to define the device-specific settings1. Variables are placeholders that can be replaced with different values for different devices1. This way, you can deploy a standard config with device-specific settings using one configuration plan1.

Correct Answer: A

Creating two ERPS instances for the ring and assigning different VLANs and different RPLs to each instance 1s part of a valid strategy for load sharing traffic across the links in an ERPS solution1. ERPS is a protocol that provides protection and recovery for Ethernet traffic in a ring topology1. It uses a RPL to block one of the links in the ring and prevent loops1. By creating two ERPS instances with different RPLs, you can use both links in the ring for different VLANs and achieve load sharing1.

Correct Answer: A

Deploying Aruba 83xx 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. The Aruba 83xx switches are designed for data center spine or core roles, and they provide high performance, scalability, and resiliency. They can support very large three-tier data center networks with up to 512 leaf switches using VSX2.
