Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 63

By default, in the SNMP protocol, which port number is used by the proxy process to send alarm messages to the NMS?

Answer options

• A. 164
• B. 161
• C. 163
• D. 162

Correct answer: D

Explanation

The correct answer is D, as port 162 is specifically designated for SNMP trap messages, which are used to send alarm notifications to the Network Management System (NMS). Options A, B, and C are incorrect because they correspond to different SNMP functions; port 161 is used for SNMP requests and responses, while ports 163 and 164 are not standard for SNMP operations.
