* 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).

Which of the following statements is false about virtual system resource allocation?
A. Improper resource allocation may prevent other virtual systems from obtaining resources and services from running properly.
B. Quota-based resources are automatically allocated based on system specifications.
C. To manually allocate resources to a virtual system, an administrator needs to configure a resource class, specify the guaranteed quota and maximum quota of each resource in the resource class, and bind the resource class to the virtual system.
D. Virtual systems can share and preempt resources of the entire device. Such resources can be manually allocated.
正解：B
解説：
Comprehensive and Detailed Explanation:
* Virtual system resource allocation can bemanual or shared.
* Manual allocationrequires configuring aresource class, defining aquota, and binding it to a virtual system.
* Why is D false?
* Quota-based resources are not automatically allocated.
* An administrator must defineresource quotas.

Which of the following technologies does not belong to outbound intelligent uplink selection?
A. Smart DNS
B. PBR
C. ISP-based route selection
D. Global route selection policy
正解：B
解説：
Comprehensive and Detailed Explanation:
* Outbound intelligent uplink selectionenables optimal routing decisions based on network conditions.
* Smart DNS, Global Route Selection Policy, and ISP-Based Route Selectionare all part of intelligent uplink selection.
* Why is A incorrect?
* PBR is NOT an intelligent uplink selection technology; it applies static rules for traffic forwarding instead.

質問 # 37
*In the data filtering profile on the firewall, keyword group "Keyword" is invoked in the upload direction of HTTP applications, the action is block, and the keyword group is invoked in the security policy. Given this, if the regular expression "b.d" is configured in the keyword group "Keyword," which of the following texts can be posted by internal employees on the forum?
A. beside
B. abroad
C. bad
D. boring
正解：D
解説：
Comprehensive and Detailed Explanation:
* Regular expressions (regex) are used in data filtering to detect patterns in traffic.
* *b.d Explanation:
* b# The word must start with 'b'.
* .* # Matches any number of characters (wildcard).
* d# The word must end with 'd'.
* Testing the given words:
* A. abroad (#matches)# Starts with "b" but does not end with "d".
* B. beside (#matches)# Starts with "b" but does not end with "d".
* C. boring (#allowed)# Doesnotstart with "b" and end with "d" (safe to post).
* D. bad (#blocked)# Starts with "b" and ends with "d" (matches the regex).
* Why is C correct?
* "boring" does not match the regex pattern, so it is not blocked.

質問 # 38
When gateways are connected using GRE over IPsec, the IPsec encapsulation mode must be tunnel mode.
A. TRUE
B. FALSE
正解：A
解説：
Comprehensive and Detailed Explanation:
* GRE over IPsecis used totunnel non-IP traffic, multicast, and dynamic routing protocolsover IPsec VPN.
* Tunnel mode is requiredbecause:
* Transport mode only encrypts the payload, but GRE needs the entireoriginal IP packet encrypted.
* Tunnel mode encrypts the entire packet(original + GRE headers), ensuring full encapsulation.
* Why is this statement true?
* GRE over IPsec must use tunnel modeto fully encapsulate and protect packets.
