Huawei HCIE-Datacom V1.0 Sample Questions (Q285-Q290):

NEW QUESTION # 285
What is the following description of MPLS incorrect?

Answer: D


NEW QUESTION # 286
Which of the following attacks are DoS (Denial of servioe) attacks?( Multiple choice question)

Answer: A,C


NEW QUESTION # 287
You try to trace a remote Internet address on your PC, but the traceroute stops after it reaches a router, and currently, the router should be in the incoming direction of the serial interface With an ACL "rule5 permit tcp source any destination any", you need to add which of the following ACLs to the router for traceoute to work

Answer: C


NEW QUESTION # 288
The following information is displayed during OSPF troubleshooting. Based on this information, which of the following is the cause of the failure in establishing an OSPF adjacency relationship?
<Huawei>display ospf error interface GigabitEthernet 0/0/0
OSPF Process 1 with Router ID 10.0.12.2
OSPF error statistics
Interface: GigabitEthernet0/0/0 (10.0.12.2)
General packet errors:
0 : Bad version 0 : Bad checksum
0 : Bad area id 0 : Bad authentication type
0 : Bad authentication key 0 : Unknown neighbor
0 : Bad net segment 0 : Extern option mismatch
0 : Router id confusion
HELLO packet errors:
2 : Netmask mismatch 0 : Hello timer mismatch
0 : Dead timer mismatch 0 : Invalid Source Address

Answer: A

Explanation:
According to the displayed OSPF error statistics from the Huawei device, the key HELLO packet error shown is:
yaml
CopyEdit
2 : Netmask mismatch
This indicates that the OSPF adjacency formation is failing due to a subnet mask mismatch between the two OSPF neighbors on the corresponding interface (GigabitEthernet 0/0/0). OSPF uses the subnet mask in Hello packets to ensure that neighbors are in the same network. If the masks do not match, OSPF will not form an adjacency.
From the Huawei Official HCIE-Datacom Study Guide (Version 3.0) - under the OSPF Troubleshooting Section:
"Netmask mismatch: If the subnet mask configured on the interfaces of OSPF neighbors does not match, a 'Netmask mismatch' error occurs. OSPF requires neighbors to be on the same subnet to establish an adjacency. This is a common reason for failure in adjacency formation." (Reference: Huawei HCIE-Datacom V3.0, OSPF Troubleshooting Chapter, Section 4.2 - OSPF Hello and Adjacency Establishment Issues) Thus, among the given options:
A . Area type inconsistency would result in an area ID mismatch error, not netmask.
B . Authentication mismatch would show a bad authentication key or type error.
D . Hello interval mismatches would trigger a Hello timer mismatch error.
Only C. The IP address masks of the interfaces are inconsistent directly matches the actual error observed: Netmask mismatch.


NEW QUESTION # 289
In the following figure, a GRE tunnel is established between R1 and R2. If the command ping -a 10.1.1.1
10.3.1.1 is run on R1, which of the following statements is correct about the ICMP packet sent by GE0/0/1 of R1?

Answer: B,D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
1. GRE Tunnel Configuration Details:
GRE (Generic Routing Encapsulation)is used to encapsulate packets for transmission between two endpoints.
The tunnel is created betweenR1andR2:
R1 Tunnel IP:10.1.1.1
R2 Tunnel IP:10.3.1.1
Source IP of Tunnel:10.0.12.1 (R1)
Destination IP of Tunnel:10.0.12.2 (R2)
The command used: ping -a 10.1.1.1 10.3.1.1
Source IP (Inner IP):10.1.1.1
Destination IP (Inner IP):10.3.1.1
2. GRE Encapsulation Process:
When thepingcommand is executed from R1 to R2 through the GRE tunnel:
Theoriginal ICMP packetwill have:
Source IP:10.1.1.1
Destination IP:10.3.1.1
This ICMP packet (inner packet) will be encapsulated using GRE.
GRE Encapsulation:
Outer IP Header:
Source IP:10.0.12.1 (R1 GE0/0/1 interface)
Destination IP:10.0.12.2 (R2 GE0/0/1 interface)
Inner IP Header:
Source IP:10.1.1.1 (Tunnel0/0/0 on R1)
Destination IP:10.3.1.1 (Tunnel0/0/0 on R2)
Theouter IP headeris used fortunnel routingbetween thephysical interfaces(GE0/0/1).
Theinner IP headerrepresents thelogical tunnel IPsused for communication between R1 and R2.
3. Correct Answer Analysis:
Option A:
Correct.
Theouter IP headeraddresses are10.0.12.1and10.0.12.2, representing thephysical interfaces (GE0/0/1)used to establish the tunnel.
Option C:
Correct.
Theinner IP headeraddresses are10.1.1.1and10.3.1.1, representing thelogical tunnel interfacesused for communication.
4. Why Other Options Are Incorrect:
Option B:
Incorrect.
Thedestination IP in the outer headershould be thepeer physical IP (10.0.12.2), not the tunnel IP (10.3.1.1).
Option D:
Incorrect.
Theinner IP destinationis thetunnel IP (10.3.1.1), not thephysical IP (10.0.12.2).
