Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q291-Q296):

NEW QUESTION # 291
What are the main types of ISIS Hello messages? (Multiple choice)

Answer: B,C,D


NEW QUESTION # 292
OSPF has multiple types of routes with varying priorities. Which of the following types of routes has the lowest priority when they have the same prefix?

Answer: D

Explanation:
OSPF Route Preference Hierarchy:
OSPF uses the following preference order for route types when the prefix is the same:
Intra-area routes (D): Routes within the same OSPF area have the highest priority.
Inter-area routes (B): Routes between different OSPF areas are preferred after intra-area routes.
Type 1 external routes (A): External routes redistributed into OSPF, considering the internal OSPF cost to the ASBR.
Type 2 external routes (C): External routes redistributed into OSPF, ignoring the internal OSPF cost to the ASBR.
Lowest Priority:
Type 2 external routes (C) are given the lowest priority because they represent external information that does not consider internal OSPF costs.


NEW QUESTION # 293
OSPF networks are classified into four types of networks by link layer protocol. Drag the following link layer protocols to the corresponding network types.(Token is reusable)

Answer:

Explanation:

Explanation:
Network Types and Corresponding Link Layer Protocols
Broadcast: Ethernet
Point-to-Point (P2P): PPP, HDLC
Point-to-Multipoint (P2MP): PPP
Non-Broadcast Multi-Access (NBMA): Frame Relay
OSPF Network Types:
OSPF classifies networks based on link layer protocols into the following types:
Broadcast: This type assumes that all routers on the network can communicate directly with one another using multicast or broadcast frames. Ethernet networks are typical examples.
Point-to-Point (P2P): This type is used for links that connect two routers directly. Common protocols include PPP (Point-to-Point Protocol) and HDLC.
Point-to-Multipoint (P2MP): This type simulates multiple point-to-point connections over a single physical network, often used in WAN scenarios where PPP is employed.
Non-Broadcast Multi-Access (NBMA): These networks connect multiple devices but lack native broadcast capability, such as Frame Relay.
Reference: HCIP-Datacom-Core Technology Training Material (OSPF Network Types).
Explanation of Matches:
Broadcast - Ethernet: Ethernet supports broadcast and multicast communication, making it a suitable example of a broadcast OSPF network.
P2P - PPP, HDLC: Both PPP and HDLC are designed for direct communication between two nodes, fitting the P2P category.
P2MP - PPP: In WANs, PPP often operates in a point-to-multipoint configuration, simulating separate connections for each endpoint.
NBMA - Frame Relay: Frame Relay is a classic NBMA technology where direct communication between devices requires manual configuration, as there is no inherent broadcast capability.
Conclusion:This classification ensures that OSPF operates efficiently over different network types by adapting neighbor discovery and LSA propagation mechanisms to the underlying link layer technology.
