Huawei's iMaster NCE-FabricInsight is an intelligent O&M platform for data center networks that leverages knowledge graph modeling to enhance network management and troubleshooting. Below is an explanation of each option:

"1-3-5" troubleshooting : This refers to a structured approach for fault detection, isolation, and resolution within 1 minute of fault detection, 3 minutes of fault location, and 5 minutes of fault recovery. FabricInsight uses AI-driven analytics to achieve this level of efficiency.

Data plane verification (DPV) : DPV ensures the correctness of the data forwarding path by verifying configurations and detecting anomalies in real time. This helps prevent issues like misconfigurations or routing errors.

Network snapshot comparison : This feature allows administrators to compare network states at different points in time, helping identify changes that may have caused performance degradation or faults.

Network health evaluation : FabricInsight continuously monitors the network and evaluates its health status, providing insights into potential risks and optimization opportunities.

All four options are valid O&M services provided by iMaster NCE-FabricInsight.

MACsec (Media Access Control Security)is a Layer 2 encryption protocol designed to secure Ethernet communications. It provides confidentiality, integrity, and replay protection for data transmitted over wired networks. The IEEE standard corresponding to MACsec is802.1AE, which defines the protocol's mechanisms for encrypting and authenticating Ethernet frames.Other options refer to unrelated standards:

802.1ab:Defines Link Layer Discovery Protocol (LLDP) for network discovery.

802.1p:Specifies priority tagging for Quality of Service (QoS).

802.1at:Defines Power over Ethernet Plus (PoE+).
