Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q201-Q206):

NEW QUESTION # 201
BGP is a distance-vector protocol that implements route reachability between ASs and selects optimal routes.
Which of the following statements are true about this protocol?

A. BGP does not support authentication. Therefore, it cannot ensure network security.
B. BGP provides various routing policies.
C. BGP supports automatic peer discovery.
D. BGP uses TCP as the transport layer protocol.

Answer: B,D

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Overview of BGP:
BGP (Border Gateway Protocol) is an Exterior Gateway Protocol (EGP) designed to exchange routing information between different Autonomous Systems (ASs) on the internet. Unlike traditional distance-vector protocols (like RIP), BGP is considered a path-vector protocol, as it not only determines reachability but also ensures policy-based routing decisions and advanced path selection mechanisms.
2. Analysis of Each Option:
Option A: BGP does not support authentication. Therefore, it cannot ensure network security.
* This statement is incorrect.
* BGP supports authentication using mechanisms such as TCP MD5 (Message Digest 5) and TCP-AO (Authentication Option). These authentication mechanisms ensure that BGP messages are not tampered with or intercepted during transmission, enhancing network security.

NEW QUESTION # 202
On an OSPF or IS-IS network, the filter-policy import command can be run on a router to filter out the LSAs forwarded by its neighbors.

A. FALSE
B. TRUE

Answer: A

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Understanding LSA Filtering in OSPF and IS-IS:
* The filter-policy command is used in OSPF and IS-IS to control which routing information is imported into the local routing table or advertised to other neighbors.
* However, it cannot filter LSAs forwarded by neighbors. In OSPF and IS-IS, LSAs are always forwarded unchanged within the area to ensure all routers have a consistent link-state database.
* Filtering only affects the routes that are installed into the local routing table or advertised to other areas or neighbors.
2. Why the Statement is False:
* LSAs are forwarded without being filtered. This ensures link-state protocols maintain the same network topology view across the network.
* The filter-policy import command only controls routes that are installed into the local routing table, not the forwarding of LSAs.
3. Summary:
* The statement is FALSE because LSAs cannot be filtered by filter-policy import.

NEW QUESTION # 203
On an OSPF network, all OSPF routers generate Router LSAs. If the E bit in a Router LSA is set to 1, the router that generates this LSA is a/an ______.

A. IR
B. DR
C. ABR
D. ASBR

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
* Router LSAs (Type 1 LSAs) are generated by every OSPF router to describe its directly connected links and their states.
* The E (External) bit in the Options field of a Type 1 LSA indicates whether the router is acting as an Autonomous System Boundary Router (ASBR).
* If E = 1, it means that the router is an ASBR, which means it is redistributing external routes (e.g., BGP, static routes) into OSPF.
* IR (Internal Router), ABR (Area Border Router), and DR (Designated Router) do not set the E-bit in their Router LSA unless they are also ASBRs.
# Reference: Huawei HCIA-Datacom Study Guide, OSPF Router Types and LSA Options.

NEW QUESTION # 204
In BGP, Keepalive messages are used to maintain BGP peer relationships. When a BGP router receives a Keepalive message from a peer, the BGP router sets the state of the peer to Established and periodically sends Keepalive messages to maintain the connection. By default, the device sends Keepalive messages every seconds.

Answer:

Explanation:
60
Explanation:
BGP Keepalive Message Behavior
* Keepalive messages are used to maintain the Established state of a BGP peer relationship.
* The Keepalive timer determines the frequency of these messages and defaults to 60 seconds, as per the BGP specification.
HCIP-Datacom-Core Reference
* The Keepalive timer default value is covered in the BGP configuration and operational principles.

NEW QUESTION # 205
On an OSPF network, if the network type isNBMA, a router unicasts all protocol packets; if the network type isbroadcast, a router multicasts all protocol packets.

A. FALSE
B. TRUE

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
OSPF network typesaffect how protocol packets (Hello, LSA updates) are transmitted:
NBMA (Non-Broadcast Multi-Access)networks (e.g., Frame Relay) donot support multicast, so routers mustunicastOSPF packets to neighbors.
Broadcast networks(e.g., Ethernet) supportmulticastand use224.0.0.5 for Hello packetsand224.0.0.6 for DR
/BDR communication.
The statement isfalsebecause:
NBMA does not unicast all packets-only Hello packets must bemanually configuredto be unicast.
LSAs and routing updates can still be multicastif an NBMA network is configured aspoint-to-multipoint.
