H19-315 Exam Dumps and Practice Questions

Type B Protectionin GPON networks refers to link-layer redundancy, where two independent fiber paths are used to connect an ONU to the OLT. In the event of a fiber failure, the system automatically switches to the backup path.

Theminimum protection switching timefor Type B protection is50 ms, ensuring minimal disruption to services. This rapid switching time is critical for maintaining high availability and reliability in mission-critical applications.

TheNetwork Doctorfeature is designed to providereal-time network quality monitoring,pre-warning, andoptimization of link deterioration. It uses AI-driven analytics to:

Continuously monitor network performance metrics such as latency, jitter, and packet loss.

Identify potential issues before they impact services, enabling proactive maintenance.

Optimize link performance by recommending adjustments to routing, bandwidth allocation, or other parameters.

Other options like 'Service Doctor' focus on service-level diagnostics, while 'Optical Doctor' and'Fiber Doctor' are specific to optical and fiber-level monitoring, respectively.

Huawei Network Quality Monitoring Best Practices

The statement isTrue. TheHuawei EA5800 OLTemploys adistributed architectureto deliver superior performance and scalability. In a distributed architecture, processing tasks are divided among multiple components, reducing bottlenecks and improving overall system efficiency. This design allows the EA5800 to handle high-density subscriber traffic with low latency and high reliability, making it ideal for carrier-grade deployments.

Key benefits of the distributed architecture include:

High Performance Switching:Supports large-scale data forwarding with minimal delay.

Scalability:Easily accommodates additional subscribers and services.

Redundancy:Enhances fault tolerance and network availability.

ITU-T G.709 Standards for OTN

The correct answer isN402. TheN402 boardis specifically designed to support400G per wavelengthtransmission, making it ideal for high-capacity optical networks.

Key features of the N402 board include:

High-Speed Transmission:Supports data rates up to 400G per wavelength, enabling efficient traffic aggregation in backbone and core networks.

Advanced Modulation:Uses modulation schemes like DP-16QAM (Dual Polarization 16 Quadrature Amplitude Modulation) to achieve high spectral efficiency.

Flexibility:Compatible with various network architectures, including OTN, WDM, and SDH.

Scalability:Can be integrated into existing networks to boost capacity without requiring a complete overhaul.

Other options:

N220:Typically supports lower data rates (e.g., 100G).

N502:Designed for mid-range applications, not 400G.

N602:Focuses on access networks rather than high-speed backbone transmission.
