80
Explanation:
Understanding Huawei OPS and HTTP Communication
# What is Huawei OPS?
* Huawei Open Programmability System (OPS) enables API-based network automation using standard HTTP requests.
* It supports NETCONF, RESTCONF, and RESTful APIs for device management.
# Why TCP Port 80?
* Port 80 is the default port for HTTP traffic.
* Used for web-based device management, API calls, and telemetry data exchange.
* If HTTPS (secure version) is used, the default port is 443.
Why is the Answer 80?
# HTTP operates on TCP port 80 by default.# Huawei OPS uses HTTP APIs to manage network devices, making port 80 the standard option.
Real-World Application:
* Cloud-Native Network Automation: Uses HTTP-based APIs for SDN controllers and automation tools.
* Network Device Management: Enables remote configuration and monitoring over HTTP APIs.
