The ArubaOS-CX software is based on the ArubaOS-Switch software and adds data center features is not a correct description of the ArubaOS-CX architecture. The ArubaOS-CX software is a new operating system that is designed for data center and campus networks. It is not based on the ArubaOS-Switch software, which is used for legacy campus switches. The ArubaOS-CX software provides advanced features such as VSX, EVPN, NAE, REST APIs, etc1.

Aruba Fabric Composer (AFC) with Nutanix Hypervisor (AHV) integration is possible. AFC is a tool that provides automation and orchestration for managing data center networks composed of ArubaOS-CX switches. AFC can integrate with various data center software such as VMware vSphere, Nutanix AHV, Microsoft Hyper-V, etc. AFC can discover, monitor, and configure Nutanix AHV clusters and hosts using REST APIs1.

A schedule profile is a feature of ArubaOS-CX that determines the order and service of queues for transmission123. A schedule profile must be configured on every interface at all times23. The switch supports three scheduling algorithms: Guaranteed Minimum Bandwidth (GMB), Strict, and Strict EQS23. Strict scheduling gives absolute priority to a queue over other queues, regardless of the bandwidth allocation23. If the profile mixes strict priority scheduling with another scheduling algorithm, the strict priority queue must be the highest numbered queue23. Therefore, this is a rule for configuring schedule profiles on an ArubaOS-CX switch, and the correct answer is yes. For more information on schedule profiles and QoS, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet1 and the QoS Guide for your switch model23.

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 high-availability 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.

ArubaOS-CX switches are designed for enterprise campus, aggregation, and data center networking use cases1. ArubaOS-CX switches support a leaf-spine topology, which is a two-layer network architecture that provides high performance, scalability, and reliability for data center networks2. Aruba CX 8325 switches are compact 1U switches that offer high density and high speed connectivity for both leaf and spine switches3. Aruba CX 8325 switches can support up to 32 ports of 100GbE or 48 ports of 25GbE and 8 ports of 100GbE3. For a data center that requires 64 leaf switches, Aruba CX 8325 switches can be a good choice for both the leaf and spine switches, as they can provide enough bandwidth and port density for the network traffic3. Therefore, this is a correct positioning of ArubaOS-CX switches in the data center, and the correct answer is yes. For more information on ArubaOS-CX switches and data center solutions, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet and the Aruba CX Switch Series datasheets3 .
