NEW QUESTION # 15
During deployment of Portal authentication, an authentication-free rule profile needs to be configured to ensure Portal pages can be opened on authentication terminals. To achieve this purpose, the following traffic needs to be permitted in the authentication-free rule profile: DNS resolution traffic of user terminals, traffic from user terminals for accessing Portal pages, and traffic from user terminals to the RADIUS server.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
Comprehensive and Detailed Explanation:
* Authentication-free rules allow unauthenticated users to access essential services before login.
* The following traffic must be allowed before authentication:
* DNS traffic# Users need to resolve domain names for the Portal page.
* Portal page access# The captive portal must be reachable.
* RADIUS server communication# Users must authenticate via RADIUS.
* Why is this statement true?
* Without these authentication-free rules, users would be unable to reach thePortal login page.

NEW QUESTION # 16
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.

- C. AAA is mainly used for interaction between users and access devices.
- D. NAC provides three authentication modes: 802.1X authentication, MAC address authentication, and Portal authentication.
Answer: A,B,C,D
Explanation:
Comprehensive and Detailed Explanation:
* Network Access Control (NAC) and AAA work together for secure network access.
* Key functions:
* A. AAA handles user-to-device authentication.
* B. NAC handles device-to-server authentication.
* C. NAC supports 802.1X, MAC authentication, and Portal authentication.

- A. Change the default TTL value.
- B. Periodically check account permissions.
- C. Cancel default sharing.
- D. Restrict the number of users.
Answer: B,C,D
Explanation:
Comprehensive and Detailed Explanation:
* Windows system hardening improves security by reducing attack surfaces.
* Recommended security measures include:
* A. Periodically checking account permissions# Prevents unauthorized access.
* B. Canceling default sharing# Reduces exposure to remote attacks.
* C. Restricting the number of users# Limits access to essential personnel.

NEW QUESTION # 26
Which of the following statements is false about HTTP behavior?
- A. You can set an alarm threshold and a block threshold to limit the size of the upload file if file upload is allowed.
- B. 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.
- 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. 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.
Answer: B
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.

NEW QUESTION # 27
Before configuring DDoS attack defense, you must configure different thresholds for defense against different types of attacks. Each threshold can be considered an upper limit for normal network traffic.
When the rate of traffic exceeds the pre-configured threshold, the firewall considers it to be attack traffic and takes a corresponding action to defend against it.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
Comprehensive and Detailed Explanation:
* DDoS defense mechanisms rely on threshold settingsto distinguish between normal and attack traffic.
* Thresholds define:
* Maximumallowedtraffic volume.
* When exceeded, firewallstrigger mitigation actions(blocking, rate-limiting, etc.).
* Why is this statement true?
* Threshold-based detection is a fundamental part of DDoS mitigation.

NEW QUESTION # 28
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.
