Huawei H12-821_V1.0 Exam With Confidence Using Practice Dumps

[: HCIP-Datacom-Core Technology Training Material (IPv6 Address Configuration and DHCPv6)​​., Analysis of Parameters:, A. Gateway address:, False. DHCPv6 does not assign the default gateway. Instead, the default gateway is advertised by routers using Router Advertisement (RA) messages in IPv6., B. DNS server address:, True. DHCPv6 can assign the IPv6 address of DNS servers to the client., C. IPv6 address/prefix:, True. In stateful mode, DHCPv6 assigns IPv6 addresses and prefixes to clients., D. SNTP server address:, True. DHCPv6 can assign the address of an SNTP (Simple Network Time Protocol) server to synchronize time on the client., Reference: HCIP-Datacom-Core Technology Training Material (DHCPv6 Configuration and Features)​​., Conclusion:, The correct parameters that a DHCPv6 server can assign to a client are: B. DNS server address, C. IPv6 address/prefix, D. SNTP server address., , , ]

[: HCIP-Datacom-Core Technology Training Material (IS-IS DIS Election Mechanism)​​., Given DIS Priorities:, R1: Priority = 10, R2: Priority = 20, R3: Priority = 30, R4: Priority = 40, R4 has the highest DIS priority of 40, which makes it the clear choice for DIS election., Scenario Details:, Since all devices are started simultaneously, the DIS election process will follow the priorities without requiring a tie-breaker (System ID)., Conclusion:, The device with the highest DIS priority is R4, and it will be elected as the DIS., ]

[: 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., , , ]
