NEW QUESTION # 104
In addition to indicating priority, the DSCP value can also indicate the drop probability. Which of the following DSCP values is set with the highest drop probability?
Answer: B
Explanation:
Understanding DSCP & Assured Forwarding (AF) Classes
DSCP (Differentiated Services Code Point)is used forQoS (Quality of Service)classification inIP packet headers.
Assured Forwarding (AF) classesprovidefour traffic classes(AF1x, AF2x, AF3x, AF4x).
EachAF classhasthree drop precedence levels(Low = 1, Medium = 2, High = 3).
Analysis of Options:
AF43 (Answer A)#Class 4, High Drop (Highest priority, highest drop probability)# AF10 (Answer B)#Class 1, Low Drop (Lowest priority, lowest drop probability)# AF12 (Answer C)#Class 1, Medium Drop Probability# AF11 (Answer D)#Class 1, Low Drop Probability# Why AF43?
Highest priority traffic within AF Class 4.
Highest drop probability (x3)means packets aredropped firstunder congestion.
Used forpremium but non-essential services (e.g., bulk data transfer, backups).

NEW QUESTION # 105
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)
Answer: A
Explanation:
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)
NEW QUESTION # 106
You have developed a third-party Portal authentication application and connected it to iMaster NCE-Campus to perform Portal authentication for Wi-Fi users. After connecting to Wi-Fi, a user will be redirected to the login page pushed by the authentication application when visiting any website for the first time.
Answer: B
Explanation:
Comprehensive and Detailed In-Depth
In the Huawei iMaster NCE-Campus solution, when using a third-party Portal authentication application, the following process occurs:
After the Wi-Fi user connects to the network, any attempt to access a website for the first time triggers HTTP redirection.
The user is redirected to the login page provided by the third-party authentication application.
This mechanism ensures that the user authenticates before accessing external resources.
The redirection behavior is consistent with captive portal functionality, which is standard for user authentication on Wi-Fi networks.
Therefore, the statement is TRUE.

NEW QUESTION # 107
InSRv6, each time a packet passes through anSRv6 endpoint node, theSegments Leftfield valuedecrements by
1, and theIPv6 DA changes.
Answer: B
Explanation:
Comprehensive and Detailed Explanation:
#SRv6 (Segment Routing over IPv6)works byencoding a segment list in the IPv6 header.
#How SRv6 Works:
TheSegments Leftfield indicates theremaining segmentsin the path.
Eachendpoint node processes the next segmentand decrementsSegments Leftby 1.
TheIPv6 Destination Address (DA) is updatedto the next segment.
Thus, the statement isTRUE.
