The video private network transmission network has higher network security because Huawei transmission equipment supports (). (Multiple Choice)

Question

Options

• ALine encryption
• BWavelength Isolation
• CBusiness hard isolation

• A
  100% (36)

Explanation

All three options are correct because Huawei transmission equipment combines multiple layers of protection to create a highly secure private network. Line encryption (A) protects data at the optical/physical layer using algorithms that encrypt traffic directly on the transmission line, preventing interception even if the fiber is physically tapped. Wavelength Isolation (B) leverages WDM technology to assign separate wavelengths to different services, creating a physical-layer separation so that traffic on one wavelength is invisible to users on another. Business hard isolation (C) provisions dedicated, fixed bandwidth pipes per service (hard pipes), ensuring one customer's traffic is completely segregated from another's with no resource sharing.

Since all three options are correct, there are no wrong distractors in this question - this is a "select all that apply" scenario where every choice represents a real, distinct security mechanism Huawei transmission gear provides.

Memory tip: Think of the three layers as "Lock, Separate, Dedicate" - Line encryption locks the data, Wavelength Isolation separates channels physically, and Business hard isolation dedicates resources exclusively - together forming a defense-in-depth strategy for private transmission networks.
