H12-821_V1.0 Exam Dumps : HCIP-Datacom-Core Technology V1.0

[Reference: HCIP-Datacom-Core Technology Training Material (OSPF Network Types)​​.,  Explanation of Matches:, Broadcast - Ethernet: Ethernet supports broadcast and multicast communication, making it a suitable example of a broadcast OSPF network., P2P - PPP, HDLC: Both PPP and HDLC are designed for direct communication between two nodes, fitting the P2P category., P2MP - PPP: In WANs, PPP often operates in a point-to-multipoint configuration, simulating separate connections for each endpoint., NBMA - Frame Relay: Frame Relay is a classic NBMA technology where direct communication between devices requires manual configuration, as there is no inherent broadcast capability.,  Conclusion:This classification ensures that OSPF operates efficiently over different network types by adapting neighbor discovery and LSA propagation mechanisms to the underlying link layer technology., , ]

[: HCIP-Datacom-Core Technology Training Material (NDP Functions and Features)​​.,  NDP Features and Functions:, A. Address resolution:NDP resolves IPv6 addresses into MAC addresses, similar to ARP in IPv4. It uses Neighbor Solicitation (NS) and Neighbor Advertisement (NA) messages for this purpose.Reference: HCIP-Datacom-Core Technology Training Material (Address Resolution in IPv6)​., B. Neighbor state tracing:NDP tracks the state of neighbors to determine their reachability. It maintains a neighbor cache and uses NS/NA messages to verify whether neighbors are reachable.Reference: HCIP-Datacom-Core Technology Training Material (Neighbor Reachability in IPv6)​., C. Duplicate address detection (DAD):NDP ensures that IPv6 addresses are unique within a network. Before assigning an address to an interface, DAD is used to verify that no other node is using the same address. This is done via NS messages.Reference: HCIP-Datacom-Core Technology Training Material (IPv6 Address Assignment and DAD)​., D. Redirection:NDP provides redirection functionality to inform hosts of a better first-hop router for reaching a particular destination. It uses ICMPv6 Redirect messages for this purpose.Reference: HCIP-Datacom-Core Technology Training Material (NDP Redirect Functionality)​.,  Conclusion:NDP supports all the mentioned functions and features: Address resolution, Neighbor state tracing, Duplicate address detection, and Redirection, making it indispensable for IPv6 networks., , , ]
