Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q205-Q210):

NEW QUESTION # 205
Which layer of data packets does the packet filtering firewall inspect?

Answer: A


NEW QUESTION # 206
Which of the following PIM protocol packets have unicast destination addresses.

Answer: A,B

Explanation:
In the PIM protocol, Register Stop and Graft messages are sent with unicast destination addresses, typically to specific neighbors or RP (Rendezvous Point) routers. Other messages like Bootstrap and Assert use multicast addresses for broader dissemination across the network .


NEW QUESTION # 207
Which of the following scenarios is not suitable for deploying interface PBR?

Answer: A

Explanation:
Policy-Based Routing (PBR) on interfaces is used to forward traffic based on specific policies rather than the routing table. However, PBR is not suitable for modifying the next-hop of locally originated traffic. Other scenarios listed are typical use cases for interface PBR .


NEW QUESTION # 208
Different types of LSAs have different functions.
Which of the following LSAs can only be spread within a single area? (Multiple choice)

Answer: A,D


NEW QUESTION # 209
The Neighbor Discovery Protocol (NDP) is an important basic protocol in the IPv6 protocol suite and plays an important role. Which of the following functions and features does it support?

Answer: A,B,C,D

Explanation:
Neighbor Discovery Protocol (NDP):
NDP is a key protocol in the IPv6 protocol suite, replacing ARP (Address Resolution Protocol) in IPv4.
It operates using ICMPv6 (Internet Control Message Protocol for IPv6) and is critical for managing interactions between IPv6 nodes on the same link.
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, andRedirection, making it indispensable for IPv6 networks.
