Huawei HCIE-Datacom V1.0 Sample Questions (Q161-Q166):

NEW QUESTION # 161
Which of the following is not the function of OSPFv3 Link-LSAs?

Answer: D

Explanation:
Link-LSA (Type 8)in OSPFv3 performs the following:
Advertises therouter's link-local addressto neighbors.
Advertises therouter's interface IDon the link.
CarriesIPv6 prefixesassociated with the interface (since Router LSA no longer does this in OSPFv3).
TheOptions field in Link-LSAcontainscapabilities of the originating router,notthe options from Network-LSA.
So,Option D is incorrect- the Link-LSA doesnot advertise options from the Network-LSA.
Correct answer: D


NEW QUESTION # 162
There is an existing router running OSPF connected to Zone 0 and Zone 1 You configured Zone 1 as a stub zone, what classes does LSA that only operates inside Zone 1 include?

Answer: C


NEW QUESTION # 163
On an SR-MPLS network, manually configured prefix SIDs on different devices may conflict with each other.
Assume that there are four routes (prefix/mask SID) as follows.Which of the following routes will be selected according to the conflict handling principle?

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
In SR-MPLS, ifprefix SIDs conflict, the following principles are applied:
Prefix with a smaller value (numerically lower SID) wins.
If the prefix length is the same, the lower SID value is selected.
In this case:
Both1.1.1.1/32 2 (A)and1.1.1.1/32 1 (B)have the same prefix length.
SinceSID 1is numericallysmallerthanSID 2,B (1.1.1.1/32 1)is selected.
The other routes (C and D) have different prefixes and do not directly conflict.


NEW QUESTION # 164
On a CloudCampus virtualized campus network, virtual networks are defined based on services. Each virtual network corresponds to a service, and isolation needs to be manually configured between virtual networks.

Answer: B

Explanation:
* Virtual Networks in Huawei CloudCampus Solution:
* Virtual networks (VNs) are segmented based on services (e.g., IoT, Guest Wi-Fi, Enterprise Wi- Fi).
* Each VN has its own routing and forwarding instance (VRF).
* Isolation Between Virtual Networks:
* By default, different virtual networks are isolated.
* If inter-VN communication is required, it must be manually configured using policy-based routing (PBR), inter-VRF routing, or firewall policies.

* Huawei CloudCampus Solution Guide - Virtual Networks and Segmentation
* HCIE-Datacom Training Material - Policy-Based Inter-VN Communication


NEW QUESTION # 165
Which of the following types of LSAs does OSPF use to support SR-MPLS?

Answer: A

Explanation:
Comprehensive and Detailed In-Depth
To support SR-MPLS (Segment Routing over MPLS), OSPF uses Type 10 Opaque LSAs to advertise Segment Routing (SR) capabilities and information.
Type 10 Opaque LSA (B): Used for distributing application-specific information within an OSPF area. In SR-MPLS, it carries the SID/Label mappings and other SR-related information.
Type 7 NSSA External LSA (A): Used to advertise external routes within an NSSA, not related to SR-MPLS.
Type 1 Router LSA (C): Advertises the router's interfaces and links but does not carry SR-specific information.
Type 2 Network LSA (D): Advertises the links of a broadcast or NBMA network, not used for SR-MPLS.
Therefore, the correct answer is B (Type 10 Opaque LSA), as it enables the advertisement of SR information.
