1️⃣Step 1: Traffic Classification and Bandwidth Policy Matching

The firewallfirst classifies trafficusing predefined bandwidth policies.

These policies match traffic based on criteria such assource/destination IP, application type, and protocol.

This step ensures that each type of traffic is categorized correctly before applying bandwidth restrictions.

2️⃣Step 2: Traffic Processing Based on Bandwidth Policies

Once traffic is classified,the firewall enforces bandwidth limits and security actions:

Traffic exceeding the assigned bandwidth is discarded or throttled.

Service connection limits are enforced to prevent excessive connections per user or application.

3️⃣Step 3: Queue Scheduling and Priority Handling

If trafficexceeds the available bandwidth, the firewallprioritizes high-priority trafficusing queue scheduling mechanisms.

Techniques likeWeighted Fair Queuing (WFQ) and Priority Queuing (PQ)ensure thatcritical traffic (e.g., VoIP, business applications) is prioritized over less important traffic (e.g., downloads, streaming).

Comprehensive and Detailed Explanation:

iMaster NCE-Campus authentication supports multi-condition matching:

Account information(e.g., username, password, role-based policies).

SSID information(specific Wi-Fi network authentication).

Terminal IP address ranges(assigns different policies based on network segments).

Why is this statement true?

Multiple authentication conditions can be applied simultaneously to enforce flexible access control.

Comprehensive and Detailed Explanation:

IPsec VPN only supports IP unicast traffic.

Non-IP unicast packets (such as multicast and broadcast) are not natively supported.

To transmit multicast traffic over IPsec, GRE over IPsec is required.

Why is this statement true?

Standard IPsec VPN does not support non-IP unicast packets.

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.
