POST # Sending Information to the Server
* ThePOST methodin HTTP is used to send data to a web server.
* Examples include:
* Submitting login credentials.
* Posting comments or messages on a forum.
* Uploading files via web applications.
* UnlikeGET, POSThides sensitive information in the request body, making it more secure for transmitting login credentials or personal data.
Internet Access Using a Proxy # Firewall Deployment for Proxy Access
* Aproxy serverallows users toaccess the internet through a controlled gateway.
* To enforce security policies, afirewall must be deployed between the intranet and the proxy server.
* Proxies are used for:
* Content filtering(blocking unwanted websites).
* Access control(restricting web usage based on user roles).
* Anonymization(hiding the user's original IP address).
File Upload/Download Size # Controlling Upload Limits
* Firewalls and security devicescan restrict file upload/download sizesto:
* Prevent excessive bandwidth usage.
* Block potentially malicious file uploads.
* Alert and Block Thresholds:
* Alert threshold:Logs a warning if a file exceeds a specific size.
* Block threshold:Prevents files larger than the configured limit from being uploaded or downloaded.

質問 3：
Match the description about virtual systems and VPN instances.
正解：
Explanation:
1. Virtual System # Services and routes can be isolated.
* A virtual system (VS)in Huawei firewalls is afully isolated security instancewithin a single physical firewall.
* Each virtual system hasseparate services, routing tables, policies, and security rules, ensuring full isolation between different users or tenants.
2. VPN Instance # Only route isolation can be implemented.
* AVPN instance (VRF - Virtual Routing and Forwarding)providesroute isolationfor different customer networks butdoes not isolate services or security policies.
* This is typically used inMPLS VPN deploymentswhere different customers share the same physical device but need isolated routing tables.
3. VPN Instance # VPN instances are automatically generated.
* In someMPLS VPNorSDN-managed networks, VPN instances can beautomatically createdwhen customer configurations are pushed via controllers.
* Dynamic routing protocols (e.g., BGP/MPLS VPN) can automatically generateVRF instancesbased on network policies.
4. Virtual System # An instance needs to be manually created.
* Unlike VPN instances,virtual systems must be manually createdby an administrator on the firewall.
* Each virtual system functions as acompletely independent firewall, requiring manual configuration of interfaces, policies, and routing settings.

* Huawei HCIP-Security Guide# Bandwidth Management & Traffic Control Policies
* 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).
