Huawei HCIP-Security V4.0 Sample Questions (Q19-Q24):

NEW QUESTION # 19
In a Huawei network security environment, which of the following is a key advantage of using HWTACACS over RADIUS for device management authentication?
Options:

  • A. HWTACACS operates over UDP, ensuring faster communication than RADIUS.
  • B. HWTACACS provides per-command authorization, allowing different privilege levels for different users.
  • C. HWTACACS does not support accounting, while RADIUS does.
  • D. HWTACACS encrypts only passwords, while RADIUS encrypts the entire payload.

Answer: B

Explanation:
Understanding the Differences Between HWTACACS and RADIUS:
* HWTACACS(Huawei Terminal Access Controller Access-Control System) is aHuawei-enhanced version of TACACS+used forAAA (Authentication, Authorization, and Accounting).
* RADIUS (Remote Authentication Dial-In User Service)is also an AAA protocol but is mainly designed fornetwork access authentication, such asVPNs and wireless authentication.
Why is Option B Correct?
* HWTACACS supports per-command authorization, meaning administrators canassign different command privileges to different users.
* For example, ajunior network engineer may be allowed to view configurations but not modify them
, while asenior engineer has full access.
* RADIUS does not support granular command authorization, as it primarily controlsnetwork access rather than device management.


NEW QUESTION # 20
In SSL VPN, the firewall performs access authorization and control based on which of the following dimensions?

  • A. MAC address
  • B. IP address
  • C. Role
  • D. Port number

Answer: B,C

Explanation:
Comprehensive and Detailed Explanation:
* SSL VPN authorization is role-based:
* Role-based policiesdetermine user permissions.
* IP-based access controlensures users connect from allowed networks.
* Why are B and C incorrect?
* SSL VPN does not authenticate based on MAC address or port number.

NEW QUESTION # 21
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 # 22
The figure shows the defense mechanism of an HTTP flood attack. Which source IP detection technology is displayed in the figure?

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

Answer: D

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.
