Comprehensive and Detailed Explanation:

Response actions for abnormal file identification in Huawei firewalls include:

A. Alert→ Logs the event but does not stop the file.

B. Block→ Prevents the file from being accessed or downloaded.

D. Delete→ Removes the malicious file before it reaches the user.

Why is C incorrect?

Allowing an identified abnormal file defeats the purpose of security enforcement.

Comprehensive and Detailed Explanation:

Heartbeat linksbetween firewalls ensuresynchronization and failover.

Layer 2 or Layer 3 configuration depends on deployment needs, but there isno strict 30% bandwidth rulefor Eth-Trunk heartbeat links.

Why is this statement false?

The30% threshold condition is incorrect.

Eth-Trunk heartbeat links aretypically Layer 3 for better failover and routing control.

Comprehensive and Detailed Explanation:

Huawei firewalls come with a built-in URL filtering database, which includes predefined categories such as:

Malicious websites

Phishing sites

Social media

Business services

The URL category database is periodically updated by Huawei, ensuring that new threats are detected automatically.

Why is this statement true?

Administrators do not need to manually load URL categories; they are delivered with the firewall and updated regularly.

Comprehensive and Detailed Explanation:

Huawei's Anti-DDoS solution has three core components:

A. Detecting center→ Monitors and detects attack traffic.

B. Management center→ Controls and configures security policies.

D. Cleaning center→ Mitigates attack traffic and allows normal traffic.

Why is C incorrect?

"Zone" is not a specific Huawei Anti-DDoS component.

Comprehensive and Detailed Explanation:

Firewalls with advanced security features(such asIPS, Antivirus, and File Filtering) candetect and respond to file anomalies.

Actions that can be taken when an anomaly is detected:

A. Alarm→ Generates a log entry and notifies the administrator.

C. Block→ Prevents the file from being transferred.

D. Delete attachment→ Removes malicious attachments from emails.

Why is B incorrect?

Allowing a detected malicious file is not a valid security response.

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:

Hot standby networkingensureshigh availabilityby keeping a backup firewall ready in case of failure.

Two main modes exist:

Active/Standby Mode→ One firewall is active, and the other remains standby. Configuration is synchronized fromactive → standby.

Load-Sharing Mode→ Both firewallsprocess traffic simultaneously, improving performance.

Why is A false?

InLoad-Sharing Mode, both firewalls are active, butconfiguration synchronization does not cause conflicts. Instead, the firewalls synchronize states properly.

Why is D false?

InLoad-Sharing Mode, configuration is always synchronizedfrom the active firewall to the standby firewall, not the other way around.
