質問 # 274
IS-IS supports the processing and computation of IPv6 routes by adding ATLPs to carry IPv6 addresses and reachability information.
正解：B
質問 # 275
Which of the following statements about VXLAN principles is incorrect?
正解：A
解説：
Understanding VXLAN (Virtual eXtensible LAN) Technology
VXLAN is a Layer 2 over Layer 3 encapsulation protocol designed to extend Layer 2 domains across routed networks using MAC-in-UDP encapsulation.
🔹 Key VXLAN Components:
VTEP (VXLAN Tunnel Endpoints): These encapsulate and decapsulate VXLAN packets.
Underlay Network: The routed IP network that forwards VXLAN packets (does not require VXLAN awareness).
Overlay Network: The logical Layer 2 segments tunneled over VXLAN.
Analysis of the Answer Choices:
✅ A. VXLAN uses MAC-in-UDP encapsulation to encapsulate Ethernet packets into UDP packets and thereby extend Layer 2 networks.
Correct: VXLAN uses MAC-in-UDP encapsulation, meaning that the original Ethernet frame is placed inside a UDP packet, allowing Layer 2 networks to extend over IP-based networks.
❌ B. When VXLAN is deployed, in addition to devices at both ends of a VXLAN tunnel, intermediate forwarding devices are also required to support VXLAN. Otherwise, VXLAN packets cannot be forwarded.
Incorrect: VXLAN packets are forwarded as regular UDP traffic in the underlay network.
Intermediate routers or switches DO NOT need to support VXLAN, as they only forward UDP packets based on the outer IP headers.
Only VTEP devices must support VXLAN because they handle encapsulation/decapsulation.
✅ C. VXLAN packets are forwarded through routes on the underlay network, and the MAC address of the terminal in the inner data frame is not considered during underlay forwarding.
Correct: The underlay network routes VXLAN packets using outer IP headers (VTEP IP addresses), not the inner MAC address.
✅ D. VXLAN can be deployed on campus networks to implement Layer 2 and Layer 3 communication.
Correct: VXLAN is commonly used in campus networks to provide both Layer 2 bridging and Layer 3 routing across different locations.
Real-World Application:
Data Center Networks: VXLAN is widely used for multi-tenant network segmentation in cloud environments.
Enterprise Campus Networks: Enables seamless Layer 2 and Layer 3 connectivity across different buildings or locations.

質問 # 276
OSPF is deployed on a campus network to implement network interconnection. The LSDB of R2 is shown in the figure.
What can be determined from the LSDB?
正解：B、D
解説：
To analyze this question, let's break down the key concepts and the given LSDB (Link State Database) information from the figure:
Understanding the LSDB Output:
The output shows the OSPF LSDB on R2 with Router ID 10.1.123.2.
Area 0.0.0.0 (Area 0) is displayed along with several Link State Advertisements (LSAs) including Router LSAs, Network LSAs, and Summary LSAs.
Area 0.0.0.1 (Area 1) also displays Router LSAs and a Type 7 LSA (NSSA LSA) with Link-State ID 0.0.0.0.
An External LSA (Type 5) with Link-State ID 0.0.0.0 and AdvRouter 10.1.123.2 is also present.
Analysis of Each Option:
Option A: Area 1 is an NSSA.
Correct.
The presence of a Type 7 LSA (NSSA LSA) in the database indicates that Area 1 is configured as an NSSA (Not-So-Stubby Area).
NSSA allows the injection of Type 7 LSAs for external routes while blocking Type 5 LSAs from entering the area.
Option B: R2 translates Type 7 default route into Type 5 default route.
Correct.
In an NSSA, if an ABR (like R2) has the NSSA ASBR capability, it will convert Type 7 LSAs to Type 5 LSAs before injecting them into the backbone area (Area 0).
In the LSDB, we see both a Type 7 LSA (NSSA) and a corresponding Type 5 External LSA, confirming that R2 performs this translation.
Option C: R2 advertises the default route in the OSPF process.
Incorrect.
There is no indication that R2 itself is originating the default route.
The Type 7 LSA in Area 1 and the Type 5 LSA in Area 0 only indicate translation from another source, not R2 advertising it directly.
Option D: Area 1 does not have Type 3 LSAs. The possible cause is that R2 filters Type 3 LSAs in the outbound direction of Area 1.
Incorrect.
In an NSSA area, Type 3 LSAs (Inter-Area Prefix LSAs) are typically not generated for external routes.
The absence of Type 3 LSAs in Area 1 is due to the nature of NSSA itself rather than any filtering configured on R2.
質問 # 277
To obtain the token ID of iMaster NCE, you need to send an HTTP request message that includes the following Python code to invoke an iMaster NCE RESTful API.
Which of the following statements is incorrect?
import requests
nbi_name = " demo13@north.com "
nbi_pwd = " CgocVcVe1@ "
host = " 139.9.213.72 "
port = " 18002 "
URI = " /controller/v2/tokens "
post_token_url = " https:// " + host + " : " + port + URI
headers_post = { " Content-Type " : " application/json " , " Accept " : " application/json " } r = requests.post(post_token_url, headers=headers_post, json={ " userName " : nbi_name, " password " :
nbi_pwd}, verify=False)
正解：B
解説：
The provided Python code uses the requests.post() function to make an HTTP POST request to retrieve a token from iMaster NCE. The body is structured using the json={} parameter, which serializes the dictionary into JSON format. The proper content-type and accept headers are included.
Let ' s analyze each option:
# Option A is correct: The print(r.json()) is a valid method to display JSON response from the server.
# Option B is correct: The token URL is constructed correctly: https://139.9.213.72:18002/controller/v2
/tokens.
# Option C is correct: The request body is clearly in JSON format, specified by the json={...} argument.
# Option D is incorrect: The HTTP method used is POST, not GET. The statement is false, making it the correct answer to select.
Huawei Official Documentation Reference:
"To obtain a token, the client sends a POST request to /controller/v2/tokens, including credentials in the request body in JSON format." (Source: Huawei iMaster NCE RESTful API Reference Guide - Authentication Section)
