Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q87-Q92):

NEW QUESTION # 87
After which of the following parameters are modified does an IS-IS neighbor relationship need to re- established?

A. The IP address of an ISIS interface is changed.
B. The cost of an IS-IS interface is changed.
C. The interval at which an IS-IS interface sends IIH packets is changed.
D. The level of an ISIS interface is changed.

Answer: D

Explanation:
When the level of an IS-IS interface is changed, the adjacency must be re-established because IS-IS adjacencies are formed based on matching levels (Level-1, Level-2, or both). Other changes, such as cost or hello intervals, do not disrupt the existing adjacency but might impact routing metrics or timing .

NEW QUESTION # 88
During routine O&M, the administrator checks the IGMP configuration on a router interface. The configuration is as follows:
<RTA> display igmp interface
Interface information of VPN-Instance: public net
GigabitEthernet0/0/1(192.168.1.1):
IGMP is enabled
Current IGMP version is 2
IGMP state: up
IGMP group policy: none
IGMP limit: -
Value of query interval for IGMP (negotiated): -
Value of query interval for IGMP (configured): 60 s
Value of other querier timeout for IGMP: 0 s
Value of maximum query response time for IGMP: 10 s
Querier for IGMP: 192.168.1.1 (this router)
Given this, which of the following statements are true?

A. The IGMP version is IGMPv2.
B. The maximum response time to Query messages is 10s.
C. The IP address of the interface is 192.168.1.1.
D. The interval for sending Group-Specific Query messages is 60s.

Answer: A,B,C,D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
* A. TRUE # The interface GigabitEthernet0/0/1 has an IP address of 192.168.1.1.
* B. TRUE # The IGMP version is explicitly stated as IGMPv2.
* C. TRUE # The maximum query response time for IGMP is set to 10 seconds.
* D. TRUE # The IGMP Query Interval is configured as 60 seconds, meaning the router sends Group- Specific Queries every 60 seconds.

NEW QUESTION # 89
In inter-AC roaming scenarios, an AC can function as the mobility server of multiple mobility groups, but can be added only to one mobility group.

A. TRUE
B. FALSE

Answer: A

Explanation:
In inter-AC roaming scenarios, an AC (Access Controller) can serve as the mobility server for multiple mobility groups, enabling it to manage roaming among multiple groups. However, an AC can only belong to one specific mobility group. This constraint ensures that mobility management remains streamlined and avoids conflicts. Huawei WLAN mobility configuration guides validate this setup .

NEW QUESTION # 90
As shown in the figure, SWA, SWB, and SWC run the Rapid Spanning Tree Protocol (RSTP). What are the roles of SWB's GE0/0/2 and SWC's GE0/0/1?

A. Backup port, alternative port
B. Alternative port, backup port
C. Root port, designated port
D. Backup port, root port

Answer: C

Explanation:
In the topology, SWB's GE0/0/2 is the Root Port because it has the least cost path to the Root Bridge (SWA).
SWC's GE0/0/1 is the Designated Port because it forwards traffic to SWA while maintaining the shortest path to the Root Bridge. This setup ensures efficient traffic flow in the spanning tree topology .

NEW QUESTION # 91
In IPv6, to communicate with a destination host, a host must obtain the link-layer address of the destination host through ARP.

A. TRUE
B. FALSE

Answer: B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. IPv6 and Neighbor Discovery Protocol (NDP):
In IPv4, a host usesARP (Address Resolution Protocol)to map an IP address to a MAC address for communication.
In IPv6,ARP is not used. Instead, IPv6 uses theNeighbor Discovery Protocol (NDP)for address resolution.
2. Why the Statement is FALSE:
IPv6 does not use ARP for resolving link-layer addresses.
IPv6 uses NDP, which operates through ICMPv6 messages to perform the equivalent function.
3. Summary:
The statement is FALSE because IPv6 uses NDP, not ARP, to obtain the link-layer address of the destination host.
Reference:
Huawei HCIA-Datacom Study Guide, Chapter "IPv6 Basics."
RFC 4861: Neighbor Discovery for IP version 6 (IPv6).
