H12-891_V1.0 Exam Facts: Simulator, Companies and Formats

Why do most candidates choose Test4Cram for H12-891_V1.0?

Because preparation here is practical and self-correcting. 323 practice questions for the H12-891_V1.0 exam carry verified answers, the simulator marks every attempt and flags the wrong ones for repeat practice until mastery, and the whole package — PDF, software, online — stays current with daily checks. Individuals prepare for their own certifications; companies prepare whole teams with us. Either way, the material works the same way: rehearse, see your mistakes, fix them.

How is the H12-891_V1.0 exam weighted by topic?

The official Huawei HCIE-Datacom V1.0 outline distributes weight this way:

Campus Network Planning and Deployment (23%)

Let the heavy domains anchor your simulator sessions, and let the flagged wrong questions from each run decide where your next hour goes.

Are there prerequisites for H12-891_V1.0?

Recommended to hold HCIP-Datacom-Core Technology certification; 5+ years of relevant network engineering experience suggested; must pass written exam before taking lab exam

Why do most candidates prefer the simulator over the PDF?

Feedback is the difference. The PDF version serves printing and handwritten annotation well, but it cannot watch you practice. The H12-891_V1.0 simulator recreates the real test scene, marks your performance automatically, points out the questions you answered incorrectly, and keeps them flagged so you rehearse them until mastery — the moment exam nervousness disappears. For pure reading and note-taking, the PDF remains excellent; for becoming exam-ready, most candidates rightly choose the simulator.

Question #4

Fill in Blank
Huawei Open Programmability System (OPS) uses HTTP methods to access managed objects to manage network devices. HTTP is the most widely used network transmission protocol on the Internet. By default, which TCP port number is used?

Reveal Solution Discussion 0

Correct Answer:

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.

Question #5

When MPLS/BGP IP VPN is deployed, which of the following statements is incorrect about BGP route exchange between PEs and CEs?

A. In a Hub&Spoke scenario, when Hub-CE and Hub-PE run an IGP for communication, EBGP cannot be configured on Spoke-PE or Spoke-CE.
B. In a scenario where PEs and CEs use BGP to exchange routing information, if two VPN sites have the same private AS number, the AS number replacement function can be used to replace the AS number in a received private network route with any specified AS number. This prevents routes from being discarded because of repeated AS numbers.
C. When PEs and CEs use BGP to exchange routing information, you do not need to import private network routes to BGP on PEs.
D. In a CE multi-homing scenario, the BGP AS number replacement function may cause routing loops. BGP SoO can be used to prevent routing loops at a VPN site.
