* Huawei QoS Configuration Guide# Traffic Classification, Policing, and Queue Scheduling
1##Step 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.
2##Step 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.
3##Step 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).

IPsec VPN does not support encapsulation of non-IP unicast packets.
A. FALSE
B. TRUE
Answer: B
Explanation:
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.

NEW QUESTION # 25
The Nginx application is deployed on a Linux host. By checking Nginx logs, O&M engineers can obtain the complete URL information submitted by users and determine whether the Linux host is under SQL injection attacks.
A. FALSE
B. TRUE
Answer: B
Explanation:
Comprehensive and Detailed Explanation:
* Nginx logs store detailed HTTP request information, including:
* RequestedURLs
* ClientIP addresses
* Query parameters(which may contain SQL injection attempts)
* SQL injection detection using logs:
* SuspiciousSQL keywordsin GET/POST requests (e.g., ' OR 1=1 -- or UNION SELECT).
* Repeated attack attemptsfrom a single source IP.
* Why is this statement true?
* Nginx logs provide full request details, enabling engineers to detect SQL injection attempts.

NEW QUESTION # 26
The difference between DoS attacks and DDoS attacks is that DoS attacks are usually directly initiated by attackers, whereas DDoS attacks are usually initiated by attackers controlling multiple zombies.
A. FALSE
B. TRUE
Answer: B
Explanation:
Comprehensive and Detailed Explanation:
* DoS (Denial-of-Service)# A single attacker sends excessive traffic to a target.
* DDoS (Distributed Denial-of-Service)# Uses multiple compromised devices (zombies or botnets) to amplify the attack.
* Why is this statement true?
* DDoS attacks originate from multiple sources (botnets), unlike DoS attacks.

NEW QUESTION # 27
Which of the following methods are used by flood attacks to cause denial of services?(Select All that Apply)
A. Exhaust network device resources.
B. Control network host rights.
C. Exhaust server-side resources.
D. Exhaust available bandwidth.

* Correct answers:
* A. Exhaust available bandwidth# Large amounts of traffic saturate the network.
* B. Exhaust server-side resources# High CPU/memory usage causes server crashes.
* D. Exhaust network device resources# Firewalls, routers, and switches become overloaded.
* Why is C incorrect?
* Controlling host rights is related to hacking, not flooding attacks.
