Huawei Updated H12-725_V4.0 Exam Questions and Answers by patricia

Comprehensive and Detailed Explanation:

Intrusion Prevention System (IPS) logs record attack details for analysis and response.

The following information is logged:

A. Signature ID→ Unique identifier for the detected attack.

B. Source IP address of the attacker→ Identifies the origin of the attack.

C. Attack duration→ How long the attack lasted.

D. Signature name→ The specific attack detected (e.g., SQL injection).

All options are correct because Huawei NGFW logs complete IPS event details.

Comprehensive and Detailed Explanation:

iMaster NCE-Campus does not have a built-in LDAP server.Instead, it integrates with external authentication servers such as:

RADIUS servers

Active Directory (AD) with LDAP

HWTACACS servers

Why is this statement false?

iMaster NCE-Campus can connect to LDAP but does not act as an LDAP server itself.

Comprehensive and Detailed Explanation:

Firewalls enforce security policies based on rules defined by the administrator.

Data filtering rules must be explicitly referenced in security policies to take effect.

Why is this statement true?

If a filtering rule exists but is not linked to a security policy, it will not apply to network traffic.

1️⃣Understanding 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.

2️⃣What 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.

3️⃣Why 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.
