NEW QUESTION # 49
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 # 51
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. 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.
C. 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.
D. You can set an alarm threshold and a block threshold to limit the size of the upload file if file upload is allowed.

Answer: C

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.

Comprehensive and Detailed Explanation:
* Health checkensuresnetwork reliabilityby detecting link failures.
* Supports multiple protocols: ICMP, TCP, UDP, DNS, and HTTP.
* Works with PBR (Policy-Based Routing):
