Sample Questions for Huawei H19-315 Exam Preparation

Question 1

What's the minimum protection switching time of Link-layer Type B Switching?

A50ms

B3s

C3min

D1min

Correct : A

The minimum protection switching time forLink-layer Type B Switchingin GPON is50ms. Type B protection involves protecting the fiber link between the OLT and the splitter by providing redundant fibers. In the event of a fiber failure, the system switches to the backup fiber within 50ms to ensure minimal service disruption. This fast switching time is critical for maintaining high availability and reliability in GPON networks.

3s, 3min, 1min:These times are far too long for protection switching in modern optical networks, which require near-instantaneous recovery to meet SLA (Service Level Agreement) requirements.

Question 2

Which aspects does the Campus OptiX (POL) save investment from?

AOpex

BCapex

CCapex (Active Equipment, Cabling and Construct) & Opex

DCapex (Only Cabling and Construct) & Opex

Correct : C

Campus OptiX (POL) saves investment in bothCapex (Capital Expenditure)andOpex (Operational Expenditure). Specifically:

Capex Savings:POL reduces costs associated with active equipment (e.g., switches, routers), cabling, and construction by using passive optical splitters and a simplified architecture.

Opex Savings:POL lowers operational costs due to its centralized management, reduced power consumption, and lower maintenance requirements compared to traditional Ethernet-based LANs.

Option Dis incorrect because it excludes savings from active equipment, which is a significant cost component in traditional networks.
