NetEdit 2.0 is a network management tool that allows you to configure, monitor, and troubleshoot

ArubaOS-CX switches. NetEdit 2.0 can discover switches using different methods, such as IP range scan, LLDP neighbors, or manual entry. After it discovers a switch, NetEdit 2.0 does not enable SNMP on the switch, if disabled. SNMP is a protocol that allows NetEdit 2.0 to collect information and statistics from the switches, but it is not required for discovery or management. NetEdit 2.0 can use other protocols, such as REST API or SSH, to communicate with the switches1. Therefore, this is not something that NetEdit 2.0 does after it discovers a switch.

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.

IPv6 protocol cannot be encapsulated in the underlay network's IPv4 packets. EVPN is a protocol that provides layer 2 and layer 3 services over an IP network1. It uses VXLAN tunnels to encapsulate Ethernet frames in UDP packets and transport them across the underlay network1. The underlay network can use either IPv4 or IPv6 protocol, but it must match the protocol used by the VXLAN tunnels1. The statement is false because it implies that IPv6 protocol can be encapsulated in IPv4 packets, which is not possible.

Network Analytics Engine (NAE) is a built-in analytics framework for network assurance and remediation on ArubaOS-CX switches. NAE allows monitoring, troubleshooting, and proactive network management using scripts and agents. Virtual Switching Extension (VSX) is a highavailability technology that allows two ArubaOS-CX switches to operate as a single logical device. You can run NAE with VSX, but only the primary VSX member will actually run agents during normal operation. The secondary VSX member will only run agents if the primary member fails or is rebooted1. Therefore, this correctly describes NAE limitations on ArubaOS-CX switches.

Network Analytics Engine (NAE) is a built-in analytics framework for network assurance and remediation on ArubaOS-CX switches. NAE allows monitoring, troubleshooting, and proactive network management using scripts and agents. However, NAE has some limitations on the number of scripts, agents, and monitors that can run on a switch, depending on the switch model and software version1. You can check whether a switch has reached its NAE limitations with the "show capacities-status nae" command, which displays the current and maximum number of scripts, agents, and monitors supported on the switch. Therefore, this correctly describes NAE limitations on ArubaOS-CX switches.

Virtual Switching Extension (VSX) is a high-availability technology that allows two ArubaOS-CX switches to operate as a single logical device. VSX link-up delay is a feature that delays bringing downstream VSX links up, following a VSX device reboot or an ISL flap. This prevents traffic blackholing or loops due to transient conditions. The link-up delay timer is not only required when split-recovery is disabled. Split-recovery is another feature that prevents traffic blackholing or loops when the ISL link fails and then recovers. Split-recovery works by disabling the secondary VSX member's downstream links until it synchronizes with the primary member. However, split-recovery does not cover all scenarios where traffic blackholing or loops can occur, such as when both VSX members reboot simultaneously or when the ISL flaps rapidly. Therefore, it is recommended to configure the link-up delay timer even when split-recovery is enabled1. Therefore, this is not a valid guideline for configuring the switches' link-up delay settings.

ISCSI is a protocol that allows storage devices to communicate over IP networks. ISCSI traffic has different requirements than data traffic, such as low latency, high throughput, and reliability. Therefore, it is not a best practice to send data and storage traffic on the same pair of 10GbE links, as this can cause congestion and performance degradation. It is also not a best practice to use Virtual Routing and Forwarding (VRF) to tunnel ISCSI traffic through the network spine on the same links that data traffic uses. VRF is a technology that creates multiple isolated Layer 3 domains on a physical network, each with its own routing table. VRF does not provide any benefits for ISCSI traffic, as it does not guarantee bandwidth, priority, or quality of service. VRF also adds overhead and complexity to the network configuration1. Therefore, this is not a valid way to support the ISCSI requirements.

A data center network is a network that connects servers, storage devices, and other devices within a data center. A campus network is a network that connects buildings and users within a campus area, such as a university or an enterprise. Data center network traffic flows are typically east-west, which means they are between servers or devices within the data center. This is because data center applications often require high-speed communication and data exchange between servers for processing, analysis, or backup. Campus network traffic flows are typically north-south, which means they are between users or devices and external networks, such as the Internet or a wide area network (WAN). This is because campus users often access online services or resources that are hosted outside the campus network12. Therefore, this is a valid difference between a typical data center network's requirements and a typical campus network's requirements.

The exhibit shows a network topology where Switch-1 and Switch-2 are part of a Virtual Switching Extension (VSX) fabric, and the router runs OSPF on LAG 100, which is a Layer 3 LAG. The question asks how to control how core-to-access traffic is forwarded, which means how the router chooses between the two links to Switch-1 and Switch-2. To force the router to use both links, ensuring that active gateway is enabled on LAG 100 on both Switch-1 and Switch-2 is not the correct solution. Active gateway is a feature that allows both VSX members to act as the default gateway for downstream devices, using a common virtual MAC address. Active gateway does not affect how upstream devices, such as the router, forward traffic to the VSX members1. To force the router to use both links, the correct solution is to configure equal-cost multi-path (ECMP) in OSPF on the router. ECMP is a feature that allows a router to load balance traffic across multiple paths with the same cost. ECMP can be configured using the maximum-paths command and specifying how many equalcost paths the router should use2. Therefore, this does not correctly explain how to control how core-to-access traffic is forwarded.
