Huawei HCIP-Security V4.0 Sample Questions (Q50-Q55):

NEW QUESTION # 50
The Nginx application is deployed on a Linux host. By checking Nginx logs, O&M engineers can obtain the complete URL information submitted by users and determine whether the Linux host is under SQL injection attacks.

A. TRUE
B. FALSE

Answer: A

Explanation:
Comprehensive and Detailed Explanation:
* Nginx logs store detailed HTTP request information, including:
* RequestedURLs
* ClientIP addresses
* Query parameters(which may contain SQL injection attempts)
* SQL injection detection using logs:
* SuspiciousSQL keywordsin GET/POST requests (e.g., ' OR 1=1 -- or UNION SELECT).
* Repeated attack attemptsfrom a single source IP.
* Why is this statement true?
* Nginx logs provide full request details, enabling engineers to detect SQL injection attempts.

NEW QUESTION # 51
Which of the following is not a process for remote users to access intranet resources through SSL VPN?

A. Resource access
B. User login
C. Access accounting
D. User authentication

Answer: C

Explanation:
Comprehensive and Detailed Explanation:
* SSL VPN remote access process includes:
* User login# User enters credentials on the virtual gateway.
* User authentication# Credentials are verified via RADIUS, LDAP, or local authentication.
* Resource access# The authenticated user accesses intranet resources.
* Why is C incorrect?
* SSL VPN does not perform "Access accounting"(which is used in RADIUS-based AAA systems).

NEW QUESTION # 52
Arrange the steps of the bandwidth management process on firewalls in the correct sequence.

Answer:

Explanation:

Explanation:
A screenshot of a computer screen AI-generated content may be incorrect.

HCIP-Security References:
* Huawei HCIP-Security Guide# Bandwidth Management & Traffic Control Policies
* Huawei QoS Configuration Guide# Traffic Classification, Policing, and Queue Scheduling
1##Step 1: Traffic Classification and Bandwidth Policy Matching
* The firewallfirst classifies trafficusing predefined bandwidth policies.
* These policies match traffic based on criteria such assource/destination IP, application type, and protocol.
* This step ensures that each type of traffic is categorized correctly before applying bandwidth restrictions.
2##Step 2: Traffic Processing Based on Bandwidth Policies
* Once traffic is classified,the firewall enforces bandwidth limits and security actions:
* Traffic exceeding the assigned bandwidth is discarded or throttled.
* Service connection limits are enforced to prevent excessive connections per user or application.
3##Step 3: Queue Scheduling and Priority Handling
* If trafficexceeds the available bandwidth, the firewallprioritizes high-priority trafficusing queue scheduling mechanisms.
* Techniques likeWeighted Fair Queuing (WFQ) and Priority Queuing (PQ)ensure thatcritical traffic (e.g., VoIP, business applications) is prioritized over less important traffic (e.g., downloads, streaming).

NEW QUESTION # 53
The figure shows the defense mechanism of an HTTP flood attack. Which source IP detection technology is displayed in the figure?

A. 302 redirect mode
B. Basic mode
C. Enhanced mode
D. URI monitoring

Answer: C

Explanation:
1##Understanding HTTP Flood Attacks:
* An HTTP flood attackis a type of DDoS attack where an attacker sendsa large number of HTTP requeststo a target server, overloading its resources.
* Attackers often use botnets or spoofed IP addressesto send forged HTTP requests, making it difficult to differentiate between legitimate and malicious traffic.
2##What is Happening in the Figure?
* TheAnti-DDoS devicedetects an abnormally high number of HTTP requests from certain IPs.
* Itchallenges suspicious clientsby requiring them to complete an authentication step (such as entering a verification code).
* Legitimate users can pass the authentication and get whitelisted, while bots and attackers fail to respond and are blocked.
3##Why is "Enhanced Mode" the Correct Answer?
* Enhanced Modeis an advancedsource IP detection technologythat uses verificationcodes or JavaScript challenges to distinguish real users from bots.
* Key features of Enhanced Mode:
* Verification challenge(e.g., CAPTCHA, JavaScript check).
* Whitelisting of verified usersto prevent further verification delays.
* Blocks attack sources that fail to respond to verification.
* In the figure, the systemprompts suspicious users to enter a verification codebefore allowing further access.
* Attackers typicallydo not respond, while legitimate userscomplete the challenge and continue browsing normally.

NEW QUESTION # 54
Which of the following statements is false about HTTP behavior?

A. The POST method of HTTP is commonly used to send information to the server through web pages.For example, use this method when you post threads, submit forms, and use your username and password to log in to a specific system.
B. You can set an alarm threshold and a block threshold to limit the size of the upload file if file upload is allowed.
C. When the size of the uploaded or downloaded file or the size of the content obtained through the POST operation reaches the block threshold, the system blocks the uploaded or downloaded file or POST operation.
D. When the size of the uploaded or downloaded file or the size of the content obtained through the POST operation reaches the alarm threshold, the system generates a log to notify the device administrator and block the behavior.

Answer: D

Explanation:
Comprehensive and Detailed Explanation:
* Threshold settings in firewalls allow administrators to define:
* Alarm threshold# When exceeded, logs are generated.
* Block threshold# When exceeded, the action is blocked.
* Why is B false?
* The alarm threshold does not block traffic; it only generates logs.
* Only the block threshold enforces blocking actions.
