                                  Huawei HCIE-Datacom V1.0 Sample Questions (Q308-Q313):

                                  NEW QUESTION # 308
                                  OSPFv2 is an IGP running on IPv4 networks, whereas OSPFv3 is an IGP running on IPv6 networks. OSPFv2 and OSPFv3 have similar LSA types, but their LSA functions are slightly different. Which of the following is not an OSPFv3 LSA type?

                                  Answer: C

                                  Explanation:
                                  Comprehensive and Detailed Explanation:
                                  OSPFv2 (for IPv4) and OSPFv3 (for IPv6) LSAs differ in function and naming conventions.
                                  Key Differences in OSPFv3 LSAs:
                                  * OSPFv3 does not use ASBR-Summary-LSA. Instead, it introduces new Inter-Area Prefix LSAs (Type 3) and Inter-Area Router LSAs (Type 4).
                                  * OSPFv2 ASBR-Summary-LSA (Type 4) is replaced in OSPFv3 by Inter-Area Router LSA (Type
                                  4).
                                  OSPFv3 LSA Types:
                                  # Router-LSA (Type 1) - Describes router interfaces and links.# Network-LSA (Type 2) - Describes broadcast network links.# Inter-Area Prefix LSA (Type 3) - Replaces Summary LSAs for routes.# Inter- Area Router LSA (Type 4) - Replaces ASBR Summary LSAs.# AS-External LSA (Type 5) - Describes external routes (same as OSPFv2).
                                  Since ASBR-Summary-LSA (Type 4) does not exist in OSPFv3, the correct answer is A.

                                  Comprehensive and Detailed Explanation:
                                  # iMaster NCE-WAN provides a RESTful API for integration with third-party applications and network automation platforms.
                                  # Why RESTful API?

                                  # (B) SNMP # Used for network monitoring, not northbound integration.# (C) CLI # Used for manual command execution, not API communication.
