SNMP (Simple Network Management Protocol) supports the use of traps, which are unsolicited messages sent to the SNMP manager when specific events occur. Traps enable devices to report faults or important events as they happen, facilitating proactive fault management and quicker response times by network administrators​.

Comprehensive and Detailed Explanation:

Huawei controllers support open APIs for network programmability:✅ RESTful → Web-based API using HTTP methods.✅ OpenFlow → SDN protocol for control/data plane separation.✅ NETCONF → XML-based network configuration protocol.

❌ Incorrect Option:

AAA (Authentication, Authorization, and Accounting) is a security mechanism, NOT an open API.

✅ Reference: HCIA-Datacom SDN Guide – Open API Support

Dynamic Routing Protocol Purpose:A dynamic routing protocol's primary function is to dynamically generate and maintain routing tables by learning and sharing routing information between routers in real time. This ensures efficient path selection and adaptation to network changes​​.

Analysis of Options:

Option A: "Generate an IP address" is unrelated to routing protocols; IP address assignment is handled by DHCP or manual configuration.

Option B: "Manage routers" is inaccurate, as dynamic routing protocols do not manage router hardware or administrative tasks.

Option C: "Generate a routing table" is correct because routing protocols dynamically compute and update routing tables based on network topology changes.

Option D: "Control the status of router interfaces" refers to interface management, which is not a function of dynamic routing protocols.

Correct Answer:The main function of a dynamic routing protocol is C (Generate a routing table).
