Huawei HCIE-Datacom V1.0 Sample Questions (Q207-Q212):

NEW QUESTION # 207
In the following figure, OSPF is enabled on all router interfaces. The IP addresses marked in the figure belong to Loopback0 of the routers.

The Loopback0 addresses of R1 and R2 are advertised in Area 1, the Loopback0 address of R4 is advertised in Area 0, and the Loopback0 addresses of R3 and R5 are advertised in Area 2. Given this, which of the following IP addresses can ping each other?

A. 10.0.3.3 and 10.0.5.5
B. 10.0.2.2 and 10.0.5.5
C. 10.0.4.4 and 10.0.2.2
D. 10.0.2.2 and 10.0.3.3

Answer: D

Explanation:
Understanding OSPF Multi-Area Routing
# OSPF (Open Shortest Path First) is a link-state routing protocol that uses a hierarchical area design for scalability.# OSPF Areas in the Diagram:
* Area 0 (Backbone Area): Contains R4 (Loopback 10.0.4.4/32).
* Area 1: Contains R1 (Loopback 10.0.1.1/32) and R2 (Loopback 10.0.2.2/32).
* Area 2: Contains R3 (Loopback 10.0.3.3/32) and R5 (Loopback 10.0.5.5/32).
* R1 and R2 connect Area 1 to Area 0.
* R1 and R3 connect Area 1 to Area 2.
How OSPF Advertises Routes Across Areas
# Intra-area communication (within the same area) is always possible.# Inter-area communication is possible if the ABR (Area Border Router) correctly advertises routes.# OSPF does NOT automatically advertise routes from one non-backbone area (e.g., Area 2) to another (e.g., Area 0) unless explicitly allowed.
Analysis of the Answer Choices:
# A. 10.0.3.3 and 10.0.5.5 (Incorrect)
* Both R3 (10.0.3.3) and R5 (10.0.5.5) are in Area 2.
* R3 and R5 can communicate directly, but OSPF rules require an Area Border Router (ABR) to share routing information between areas.
* Since no information is provided about inter-area route redistribution, we cannot confirm that R3 and R5 can reach each other.
# B. 10.0.2.2 and 10.0.5.5 (Incorrect)
* R2 (10.0.2.2) is in Area 1, and R5 (10.0.5.5) is in Area 2.
* R2 does NOT have direct OSPF reachability into Area 2.
# C. 10.0.2.2 and 10.0.3.3 (Correct)
* R2 (10.0.2.2) is in Area 1, and R3 (10.0.3.3) is in Area 2.
* R1 connects both Area 1 and Area 2, meaning R2 and R3 can communicate via R1.
* R1 is the ABR (Area Border Router) between Area 1 and Area 2, so it will advertise routes from R3 to R2 and vice versa.
# D. 10.0.4.4 and 10.0.2.2 (Incorrect)
* R4 (10.0.4.4) is in Area 0 (Backbone), and R2 (10.0.2.2) is in Area 1.
* R2 does NOT connect directly to Area 0, so R2 does not learn routes from Area 0 unless R1 explicitly redistributes them.
* No explicit information about route redistribution is provided.
# Reference: Huawei HCIE-Datacom Guide - OSPF Multi-Area Routing & ABR Role Real-World Application:
* Enterprise WAN Networks: Multi-area OSPF is used to scale large enterprise networks while maintaining fast convergence.
* Service Provider Networks: ABRs control route distribution, preventing unnecessary flooding of routing updates across areas.

NEW QUESTION # 208
Which of the following roles is NOT a core role in Huawei's Free Mobility solution?

A. Authentication device
B. Policy enforcement device
C. Policy control device
D. iMaster NCE-Campus

Answer: A

Explanation:
Understanding Huawei's Free Mobility Solution
Huawei'sFree Mobility solutionis designed to ensure that users can seamlesslyaccess the networkregardless of their physical location while maintainingconsistent policies.
#Key Components in Free Mobility Solution:
1##iMaster NCE-Campus (Answer A - Core Role)
Manages network policies & user access.
Implementscentralized policy control & orchestration.
2##Policy Enforcement Device (Answer B - Core Role)
Ensures thatuser policies (such as QoS, security, VLANs) are applied dynamically.
Typically aswitch or gatewayenforcing access control.
3##Policy Control Device (Answer D - Core Role)
Stores anddynamically assigns policies based on user role & device type.
Works closely withiMaster NCE-Campus.
#Why is C (Authentication Device) NOT a Core Role?
#Authentication devices (such as aRADIUS or AAA server) arenot a core componentof Huawei'sFree Mobilitysolution.
They are part of thebroader network security frameworkbutnot mandatoryfor Free Mobility.
Real-World Application:
Used inenterprise & campus networkswhereemployees, guests, and IoT devices need seamless accesswhile maintaining security policies.

NEW QUESTION # 209
The TTL field encapsulated in the MPLS label header can prevent infinite loops of MPLS packets.
Which of the following statements regarding the TTL field are correct?

A. MPLS encapsulation in frame mode supports the TTL field. MPLS encapsulation in cell mode does not support the TTL field.
B. If TTL copy is disabled, users can use the tracert function to view the LSR of the MPLS domain.
C. MPLS provides two processing modes on the TTL field:
TTL in the MPLS header copies the IP TTL value when an IP packet enters the MPLS network.
The ingress LER sets the TTL value in the MPLS header to 255.
D. The processing of IP TTL copy hides the LSR in an MPLS domain, improving network security.

Answer: A,C,D

Explanation:
The Time-To-Live (TTL) field in MPLS is essential for preventing infinite loops and enhancing security.
* MPLS TTL Field Functionality:
* It prevents packets from circulating indefinitely in the MPLS network.
* It allows traceroute (tracert) to identify MPLS hops when TTL propagation is enabled.
* Explanation of Correct Answers:# B. The processing of IP TTL copy hides the LSR in an MPLS domain, improving security.
* If TTL propagation is disabled, MPLS routers do not decrease TTL, hiding internal LSRs from traceroute, enhancing security.
# C. MPLS provides two TTL processing modes:
* Default Mode: The MPLS TTL copies the IP TTL value when an IP packet enters the MPLS network.
* Uniform Mode: The ingress LER sets the MPLS TTL to 255, so it does not decrement.
# D. MPLS encapsulation in frame mode supports the TTL field, while cell mode does not.
* Frame Mode (Ethernet, PPP, etc.) supports TTL.
* Cell Mode (ATM/MPLS) does not support TTL.
* Incorrect Answer Explanation:# A. If TTL copy is disabled, users can use the tracert function to view MPLS hops.
* Wrong! If TTL propagation is disabled, tracert cannot see LSRs inside the MPLS core network.

NEW QUESTION # 210
BGP EVPN can be used as the VXLAN control plane protocol to completely prevent traffic flooding, such as broadcast ARP packets, on the VXLAN network.

A. TRUE
B. FALSE

Answer: A

Explanation:
Understanding VXLAN and BGP EVPN Control Plane
VXLAN (Virtual eXtensible LAN)is anoverlay network technologythat enablesLayer 2 (L2) extension over an IP-based networkusingMAC-in-UDP encapsulation.
#Traditional VXLAN Flooding Issue:
Without BGP EVPN, VXLAN usesflood-and-learnbehavior for MAC address learning.
Broadcast, Unknown Unicast, and Multicast (BUM) trafficis flooded to all VTEPs, which is inefficient.
#How Does BGP EVPN Solve Flooding?
BGP EVPN (Ethernet VPN) replaces the flood-and-learn model with a distributed control plane.
MAC/IP bindings are advertised through BGP EVPN Type 2 routes, eliminating the need forflooding ARP requests.
VXLAN routers learn MAC addressesproactivelyinstead of relying on flooding.
Why is the Answer TRUE?
#BGP EVPN fully prevents ARP flooding by distributing MAC/IP bindings via control plane updates.
#VTEPs only send traffic to known destinations, reducing network congestion.
#BGP EVPN is the industry standard for large-scale data center and campus VXLAN deployments.
Real-World Application:
Data Centers:Avoids unnecessaryARP request floodingin large cloud networks.
Campus Networks:ReducesL2 broadcast storms, improving network efficiency.
Service Provider Networks:Enablesscalable multi-tenant VXLAN solutions.

A. The subscription mode is static subscription.
B. The device sends sampled data every second.
C. The subscription name is Sub1.
D. The IP address of the device is 192.168.56.1.

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Analyzing the output:
A: The device sends sampled data every second:Correct. Thesample interval is 1000 ms (1 second).
B: The subscription name is Sub1:Correct. Thesubscription nameis clearly shown asSub1.
C: The subscription mode is static subscription:Correct. Since theSub-stateisPASSIVE, it indicates astatic subscription.
