정답:
HTTP
Explanation:
(Hypertext Transfer Protocol) is the foundation of web communication and is widely used in Huawei's OPS (Open Programmability System) to manage devices via RESTful APIs.According to standard IANA port assignments, HTTP uses:TCP port 80 by defaultHTTPS (secured HTTP) uses TCP port 443Huawei OPS interacts with network devices using HTTP (or HTTPS) protocols for script-driven automation, and unless secured HTTPS is specified, port 80 is the standard.Correct answer: 80 IANA Service Name and Port Number Registry: https://www.iana.org/assignments/service-names-port-numbers Huawei HCIE-Datacom V1.0 Study GuideChapter: Network Automation and ProgrammabilitySection: OPS Fundamentals and HTTP Communication

When static IPsec VPN is used for WAN interconnection in the Huawei CloudCampus Solution, the AP, Router, and ____ can be used as egress devices.
정답:
Firewall
Explanation:
✔ Egress devices in Huawei CloudCampus static IPsec VPN include:
Access Points (APs)
Routers
Firewalls ✅
✔ Why Firewalls?
Firewalls support IPsec VPN termination for secure WAN interconnection.
Firewalls provide advanced security filtering and encryption for IPsec traffic.

A VGMP packet is encapsulated with a UDP header and a VGMP header. By default, a VGMP packet uses UDP port _____.
A VGMP packet is encapsulated with a UDP header and a VGMP header. By default, a VGMP packet uses UDP port _____.
정답:
Understanding VGMP (Virtual Gateway Management Protocol)
Explanation:
Understanding VGMP (Virtual Gateway Management Protocol)
🔹 What is VGMP?
VGMP (Virtual Gateway Management Protocol) is used in Huawei firewalls to manage hot standby (HRP - Hot Standby Routing Protocol).
Ensures that the active and standby firewalls synchronize their states for high availability.
🔹 How Does VGMP Work?
The Active and Standby firewalls exchange VGMP packets to maintain state synchronization.
These packets are encapsulated within UDP for transport.
The default UDP port for VGMP is 512.
Why is the Answer 512?
✅ Huawei firewalls use UDP port 512 by default for VGMP communication.
✅ This ensures that VGMP heartbeats and synchronization messages are correctly processed.
Real-World Application:
Enterprise Firewalls: VGMP ensures failover between active and standby firewalls.
Carrier-Grade Firewalls: Uses VGMP with HRP to achieve zero-downtime firewall redundancy.
