Huawei HCIP-Security V4.0 Sample Questions (Q11-Q16):

NEW QUESTION # 11
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 # 12
The figure shows the defense mechanism of an HTTP flood attack. Which source IP detection technology is displayed in the figure?

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

Answer: A

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.

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 # 14
When gateways are connected using GRE over IPsec, the IPsec encapsulation mode must be tunnel mode.

  • A. TRUE
  • B. FALSE

Answer: A

Explanation:
Comprehensive and Detailed Explanation:
* GRE over IPsecis used totunnel non-IP traffic, multicast, and dynamic routing protocolsover IPsec VPN.
* Tunnel mode is requiredbecause:
* Transport mode only encrypts the payload, but GRE needs the entireoriginal IP packet encrypted.
* Tunnel mode encrypts the entire packet(original + GRE headers), ensuring full encapsulation.
* Why is this statement true?
* GRE over IPsec must use tunnel modeto fully encapsulate and protect packets.

NEW QUESTION # 15
The difference between DoS attacks and DDoS attacks is that DoS attacks are usually directly initiated by attackers, whereas DDoS attacks are usually initiated by attackers controlling multiple zombies.

  • A. TRUE
  • B. FALSE

Answer: A

Explanation:
Comprehensive and Detailed Explanation:
* DoS (Denial-of-Service)# A single attacker sends excessive traffic to a target.
* DDoS (Distributed Denial-of-Service)# Uses multiple compromised devices (zombies or botnets) to amplify the attack.
* Why is this statement true?
* DDoS attacks originate from multiple sources (botnets), unlike DoS attacks.
