An O&M platform mainly provides unified monitoring and performance management for network devices. Which of the following is NOT device monitoring data?
Correct Answer: D
Understanding Network Monitoring Data Categories #Network devices operate across three functional planes: #A. Management Plane: Handlesdevice configuration, authentication, and monitoring. Example:SNMP, SSH, NETCONF logs. #B. Data Plane (Forwarding Plane): Handlespacket forwarding and switching. Example:Interface statistics, traffic rates, dropped packets. #C. Control Plane: Handlesrouting, signaling, and protocol operations. Example:BGP, OSPF, and MPLS signaling messages. #D. Monitoring Plane (Incorrect Choice): There is no "monitoring plane" in network architecture. Monitoring tools collect data frommanagement, control, and data planes, butdo not form a separate plane. Why is the Answer D (Monitoring-plane data)? #Monitoring-plane does not exist as a separate category in network architecture. #O&M tools collect data from management, control, and data planes, but do not define a separate "monitoring plane". Real-World Application: Huawei iMaster NCE-Campus & iMaster NCE-WANcollect real-timenetwork statistics and alarms. Network Performance Monitoring (NPM)toolsanalyze control-plane eventsto detect failures. #Reference:Huawei HCIE-Datacom Guide - Network Planes and Performance Monitoring
Question 42
The following description of Filter-Policy is correct?( Radio neck).
Correct Answer: B
Question 43
Regarding the description of the hello message in the PIM-SM message, the error is ?
Correct Answer: C
Question 44
Because BGP is an EGP routing protocol, BGP routing policies can only be deployed between EBGP neighbors, and routing policies between IBGP neighbors are not valid.
Correct Answer: A
Question 45
IPsec SAs can be established in either manual mode or IKE auto-negotiation mode. Which of the following statements about the two modes is incorrect?
Correct Answer: D
Understanding IPsec SA (Security Association) Establishment #IPsec (IP Security) provides encrypted communicationover IP networks. #Security Associations (SAs) define encryption, authentication, and key parameters for IPsec tunnels. Two IPsec SA Modes: 1##Manual Mode: All parameters (keys, encryption methods, authentication settings) must be manually configured. Keys do not change automatically, making it less secure. 2##IKE (Internet Key Exchange) Auto-Negotiation Mode: UsesIKE Phase 1 and Phase 2to automaticallynegotiate, generate, and exchange keys. Keys are periodically refreshed, increasing security. UsesDiffie-Hellman (DH) key exchangefor secure key generation. Why is Answer D Incorrect? #D. SAs established in both manual and IKE auto-negotiation modes can be dynamically updated. Incorrect:Inmanual mode, the IPsec SA isstaticand does not support dynamic updates. Correct behavior:OnlyIKE auto-negotiation modesupportsdynamic re-keying and SA updates. #Reference:Huawei HCIE-Datacom Guide - IPsec SA Modes and IKE Negotiation
