Create a separate OSPF process for each VRF on Switch-1. Then redistribute each process into the other VRFs’ processes is not a valid strategy for meeting this goal of enabling devices in VRF B and VRF C to reach shared resources in VRF A. This strategy would create unnecessary complexity and overhead on Switch-1, and it would not guarantee optimal routing between the VRFs. A better strategy would be to use inter-VRF routing or route leaking on Switch-1, which allows direct communication between different VRFs without requiring redistribution1.

The ArubaOS-CX portfolio for data center networks consists of different switches for different roles. The Aruba 8400 switches are designed for the core and aggregation layers, while the Aruba CX 6300 and CX 6400 switches are designed for the leaf layer1. Therefore, deploying Aruba 8400 switches as data center leaf switches is not how you should position switches in the ArubaOS-CX portfolio for data center networks.

A GRE tunnel interface is a virtual interface that can encapsulate different network layer protocols inside point-to-point or point-to-multipoint links over an IP network1. It can be assigned an IP address and attached to a VRF. A VRF allows multiple instances of a routing table to co-exist within the same router2. By attaching a GRE tunnel interface to a VRF, you can isolate the traffic of that tunnel from other tunnels and routing domains2.

Ring 1, instance 1: control VLAN: 1000protected VLANs: 51-135 Ring l,Instance2: control VLAN: 1001 protected VLANs: 136-220 Ring 2, Instance 1: control VLAN: 1000 protected VLANs: 181 -200 Ring 2, Instance 2: control VLAN: 1003 protected VLANs: 201 -220 is not a valid design for the control and protected VLANs on the VSX fabric 1 switches for an Ethernet Ring Protection Switching (ERPS) solution. The control VLANs must be unique for each ring instance and must not overlap with any protected VLANs. In this design, the control VLAN 1000 is used for both ring 1 instance 1 and ring 2 instance 1, which can cause conflicts and errors. Also, the protected VLANs 181-220 are used for both ring instances on ring 2, which can cause loops and traffic duplication2.

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.

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.

The solution is correct because making sure that the SSH server is enabled is a minimum requirement for setting up communications between the switch and NetEdit. NetEdit uses SSH to establish a secure connection to the switch and execute commands on it. Therefore, making sure that the SSH server is enabled is necessary for setting up communications between the switch and NetEdit.

 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.

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.

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.
