- D. Basic mode
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.

NEW QUESTION # 31
In the figure, if 802.1X authentication is used for wired users on the network, the network admission device and terminals must be connected through a Layer 2 network.
Options:
- A. TRUE
- B. FALSE
Answer: A
Explanation:
Understanding 802.1X Authentication in Wired Networks:
* 802.1X is a port-based network access control (PNAC) protocolthat requires aLayer 2 connection between thesupplicant (PC), the authenticator (switch), and the authentication server (e.g., RADIUS server).
* In wired networks,802.1X authentication occurs at the Ethernet switch (Layer 2 device), which enforces authenticationbefore allowing network access.
Why Must the Network Be Layer 2?
* 802.1X authentication operates at Layer 2 (Data Link Layer) before any IP-based communication (Layer 3) occurs.
* If the authentication device and user terminal were on different Layer 3 networks, the authentication packets (EAPOL - Extensible Authentication Protocol Over LAN)would not be forwarded.
* In the figure, the authentication control point is at theaggregation switch, which means thePC and switch must be in the same Layer 2 domain.
Components of 802.1X Authentication in the Figure:
* Supplicant (PC)# The device requesting network access.
* Authenticator (Aggregation Switch)# The switch controlling access to the network based on authentication results.
* Authentication Server (iMaster NCE-Campus & AD Server)# Verifies user credentials and grants or denies access.
* Layer 2 Connectivity Requirement# ThePC must be in the same Layer 2 networkas the Authenticatorto communicate via EAPOL.
Why "TRUE" is the Correct answer:
* 802.1X authentication is performed before IP addresses are assigned, meaning it can only operate in a Layer 2 network.
* EAPOL (Extensible Authentication Protocol Over LAN) messages are not routableand must stay within a single Layer 2 broadcast domain.
* In enterprise networks,VLAN-based 802.1X authentication is often used, where authenticated users are assigned to a specific VLAN.
