Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q260-Q265):

NEW QUESTION # 260
On an OSPF network, if two indirectly connected routers with the same router ID run in the same area, Type 1 LSA calculation fails.

A. FALSE
B. TRUE

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
* Type 1 LSAs (Router LSAs) are generated by every OSPF router to describe its directly connected links and their states.
* The Router ID (RID) must be unique in an OSPF domain; otherwise, OSPF calculations will fail due to ambiguous paths.
* If two routers in the same area have the same Router ID, OSPF will fail to calculate Shortest Path First (SPF) correctly, leading to routing inconsistencies.
* To prevent this, Huawei routers automatically detect duplicate Router IDs and prevent OSPF from functioning properly until the issue is resolved.
# Reference: Huawei HCIA-Datacom Study Guide, Chapter on OSPF LSAs and Router ID Uniqueness.

A. One VRRP device can serve as the Master device for multiple backup groups.
B. To ensure normal business, there is only one Master device in each VRRP backup group.

NEW QUESTION # 262
See the following figure. RTA, RTB, RTC, and RTD are in the same AS and establish IBGP peer relationships through direct links. RTB an RTC are route reflectors (RRs), RTA and RTC are the RR clients of RTB, and RTB and RTD are the RR clients of RTC. If RTA advertises the route 10.1.1.0/24 to the BGP process, the Originator ID of the BGP route received by RTD is------------------.

Answer:

Explanation:
1.1.1.1
Explanation:
The Originator ID in a BGP route represents the Router ID of the device that originally advertised the route into the BGP domain. Since RTA originates the route 10.1.1.0/24 into the BGP process, the Originator ID in the route received by RTD will be set to 1.1.1.1 .

NEW QUESTION # 263

By default, if no router ID is configured but multiple loopback interface addresses are configured, BGP selects the largest loopback interface address as the router ID.

A. FALSE
B. TRUE

Answer: B

Explanation:
BGP Router ID Selection Rules:
If a router ID is not manually configured:
The largest loopback address is selected as the router ID. If no loopback interfaces exist, the largest active physical interface address is selected.
Default Behavior:
This ensures that a stable and unique router ID is chosen automatically, even without manual configuration.
