H19-315 Exam Questions & Answers

The correct answer isRoom-like scenarios, including education, hotel, medical, apartment. Campus OptiX (POL) is primarily designed for enterprise campus environments where high bandwidth, low latency, and simplified network architecture are required. Common scenarios include:

Education:Connecting classrooms, dormitories, and administrative offices.

Hotels:Providing high-speed internet and IPTV services to guests.

Medical:Supporting hospital networks for patient care, imaging, and telemedicine.

Apartments:Delivering triple-play services (data, voice, video) to residents.

While options like video backhaul and Wi-Fi backhaul are valid use cases for optical networks, they are typically associated with carrier-grade solutions rather than enterprise-focused Campus OptiX deployments.

TheMS-OTN (Multi-Service Optical Transport Network)is a versatile technology designed to support multiple types of services and protocols. Here's an analysis of each statement:

Statement A:Not all models in the OSN 1800 series (e.g., OSN 1800 I) fully support MS-OTN. Only higher-end models like the OSN 1800V and OSN 1800 II provide comprehensive MS-OTN capabilities.

Statement B:MS-OTN supportsODUk (Optical Channel Data Unit)cross-connections, enabling efficient grooming and transport of traffic at various granularities.

Statement C:MS-OTN integratesSDH,PKT (Packet), andOTNservices into a singleplatform, making it ideal for converged networks.

Statement D:MS-OTN stands forMulti-Service Optical Transport Network, highlighting its ability to handle diverse traffic types.

Thus, statements B, C, and D are correct.

The correct answers arePower BoardandMain Control Board. Hardware redundancy is a critical feature of Optical Line Terminal (OLT) products to ensure high availability and fault tolerance in carrier-grade networks.

Power Board Redundancy:OLTs like the Huawei EA5800 support dual power supplies to prevent downtime in case of a power supply failure. This redundancy is essential for maintaining continuous service delivery.

Main Control Board Redundancy:The main control board manages system operations and traffic forwarding. Dual control boards ensure that if one fails, the backup takes over seamlessly, minimizing service disruption.

Other options:

Uplink Port:While uplink ports are critical for connecting the OLT to the core network, they are not typically redundant at the hardware level. Instead, redundancy is achieved through network design (e.g., multiple uplinks).

Service Port:Service ports connect to ONUs and are not individually redundant. However, the OLT's distributed architecture ensures that a failure in one port does not affect the entire system.
