質問 # 28
On the campus network shown, IPv6 is deployed for service tests. Four routers are deployed on the network, and OSPFv3 is used for IPv6 network connectivity. An engineer checks the LSDB of R2 and obtains a Link- LSA. Which of the following statements about the LSA are correct?

A. This LSA is generated by R2.
B. This LSA indicates that R2 does not support external routes but can participate in IPv6 route calculation.
C. The IPv6 address prefix of R2's GE0/0/0 is 2001:DB8:2345:23::/64.
D. The link-local address of R2's GE0/0/0 is FE80::2E0:FCFF:FECD:4F79.

正解：A、C、D

解説：
InOSPFv3,Link-LSA (Type 8)is generated by a routerfor each of its interfacesto advertise:
Therouter ' s link-local addresson that interface.
TheIPv6 prefixesassociated with the interface.
Flags and options, such as router priority or loopback indicators.
From the output:
Link-LSA (Interface GigabitEthernet0/0/0)
Originating Router: 10.1.2.2
Link-Local Address: FE80::2E0:FCFF:FECD:4F79
Prefix: 2001:DB8:2345:23::/64
A). The link-local address of R2's GE0/0/0 is FE80::2E0:FCFF:FECD:4F79# This matches the Link-Local Address field in the LSA.# B). The IPv6 address prefix of R2's GE0/0/0 is 2001:DB8:2345:23::/64# This matches the Prefix field in the LSA.# C). This LSA indicates that R2 does not support external routes but can participate in IPv6 route calculation##Incorrect.
TheLink-LSAdoesnot provide any indicationabout external route capabilities.
It simply advertisesinterface-specific IPv6 and link-local info.
Whether R2 supports external routes depends onType 5 (External) or Type 7 (NSSA) LSAs, not Link-LSAs.
D). This LSA is generated by R2# The Originating Router: 10.1.2.2 is R2's router ID, so this LSA is definitely generated by R2.# Correct Answers:A, B, D The Link-LSA in OSPFv3 contains:
The link-local address used by the originating router on the link.
A list of all IPv6 prefixes associated with the link.
Flags such as router priority and the Router-LSA options.
These LSAs are alwaysgenerated by the router itselfand arenot flooded beyond the link.

B. SSM uses only the SPT tree
C. No RP is required
D. Ideal for 1-to-many applications
E. SSM uses only shared trees

正解：B、C、D

質問 # 30
A lot of overwave techniques have emerged in the process of replacing the IPV4 addresses used in the network with lP6 addresses. These technologies are divided into two categories, one is IP4IPV6 coexistence technology, the other is PA/IP>6 interoperability technology, which of the following options sleep in IPv4/IPv6 coexistence technology?

A. IPv6 over IPv4
B. NAT64
C. Dual Stack
D. ISATAP

正解：A、C、D

質問 # 31
The following is the correct statement about the LSA of OSPFv3?

A. Router-LSA and Network-LSA does not contain routing information
B. Inter-AreaPrefix-SA's LinkStatelD contains the prefix
C. When the Intra-AreaPrefixLSA's ReferencedLinkStateType-2, referencedLinkStatelD contains the interface to DR ID
D. Inter-AreaPrefirLSA also contains LinkLocal information file

正解：A、C

質問 # 32
In the Huawei SD-WAN Solution, the topologies of different VNs must be the same.

A. TRUE
B. FALSE

正解：B

解説：
Understanding Huawei SD-WAN VN (Virtual Network) Topologies
Huawei SD-WAN uses Virtual Networks (VNs) to provide traffic isolation and policy-based routing for different services, branches, and applications.
# VN Topologies Can Be Different
* Each VN (Virtual Network) can have its own topology.
* Some VNs may use full-mesh, while others may use hub-and-spoke or star topology.
* Different VNs can have different routing and security policies.
# Example:
* Corporate traffic (VN1) # Full-mesh topology for efficient inter-branch communication.
* Guest Wi-Fi traffic (VN2) # Hub-and-spoke topology to restrict inter-site communication.
Why is the Answer FALSE?
# All VNs do not have to use the same topology.# Each VN can be configured independently with a unique topology, routing policy, and security settings.
# Reference: Huawei HCIE-Datacom Guide - SD-WAN VN Topologies and Segmentation
