You are not concerned about split brain issues in your environment, so you want the secondary member to keep its links up if the ISL fails is a use case for disabling split-recovery mode on ArubaOS-CX switches in a Virtual Switching Extension (VSX) fabric. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. The ISL is the inter-switch link that connects two VSX nodes and carries data traffic. The split-recovery mode is a feature that prevents split-brain scenarios when both VSX nodes lose connectivity with each other but remain up. When split-recovery mode is disabled, if the ISL fails but both VSX nodes remain up,

Place all three VRFs in the same OSPF process on Switch-1 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 not work because OSPF does not support multiple VRFs in the same process on ArubaOS-CX switches. Each VRF must have its own OSPF process with a unique process ID1.

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.

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.

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.
