Huawei H19-315 Exam Dumps

The correct answers areA, B, and C. Here's a detailed explanation of each statement:

A . MS-OTN is short for Multi-Service Optical Transport Network:This is correct.MS-OTNintegrates multiple technologies (e.g., OTN, SDH, Ethernet) into a single platform, enabling converged transport for diverse services.

B . MS-OTN supports SDH, PKT, and OTN services:This is correct. MS-OTN supportsSDH (Synchronous Digital Hierarchy)for legacy services,PKT (Packet)for Ethernet-based traffic, andOTN (Optical Transport Network)for high-capacity transport.

C . MS-OTN supports ODUk cross-connections:This is correct. MS-OTN leveragesODUk (Optical Channel Data Unit-k)cross-connections to efficiently switch and route traffic at the optical layer, ensuring high performance and scalability.

D . OSN 1800V, 1800II E, and 1800I E all can support MS-OTN:This is incorrect. While theOSN 1800Vand1800II Esupport MS-OTN, the1800I Eis a simpler device designed for access networks and does not fully support MS-OTN capabilities.

TheOSN 1800 Vis a compact device designed for outdoor and edge deployments. Unlike other models in the OSN 1800 series, itcannot be mounted in a standard 19-inch cabinetdue to its unique form factor and intended use case.

Here's an analysis of the other options:

OSN 1800 I:Can be mounted in a 19-inch cabinet and is commonly used in small-scale deployments.

OSN 9800 U32:A high-end platform designed for core networks, typically deployed in data centers or telecom rooms with 19-inch racks.

OSN 1800 II:Supports 19-inch cabinet mounting and is used in metro and regional networks.

Thus, theOSN 1800 Vis the correct answer.

TheNCE-T (Network Cloud Engine - Transport)follows a licensing model that includes both apermanent licenseand anSNS (Software Support and Services)annual fee. Here's how it works:

Permanent License:Grants access to the core features and functionalities of NCE-T indefinitely. This ensures long-term usability without recurring costs for the base software.

SNS Annual Fee:Covers ongoing support, software updates, bug fixes, and technical assistance. Customers must renew this annually to stay current with the latest enhancements and receive priority support.

This hybrid model is common in enterprise-grade software solutions, balancing upfront investment with ongoing operational costs.

TheFTTH (Fiber-to-the-Home)network consists of several key components that work together todeliver high-speed connectivity to end-users:

ONU/ONT (Optical Network Unit/Terminal):Customer-side device that converts optical signals into electrical signals for end-user devices.

OLT (Optical Line Terminal):Central device located at the service provider's premises, managing communication with multiple ONUs.

Splitter:Passive optical device that divides the signal from the OLT into multiple paths for distribution to ONUs.

NMS (Network Management System):Software platform (e.g., eSight) for centralized monitoring and management of the FTTH network.

ODF (Optical Distribution Frame):Infrastructure component used for organizing and connecting optical fibers.

Each of these components plays a critical role in ensuring efficient and reliable FTTH deployments.

In asafe city scenario, outdoor monitoring is a critical requirement. Huawei recommends usingoutdoor monitoring ONTslike theEG8084PandPowerCube500for such deployments. These devices are ruggedized and designed to operate in harsh environmental conditions, making them ideal for outdoor surveillance applications.

While indoor monitoring ONTs and pre-connection ODN are useful in other scenarios, they are not specifically optimized for outdoor safe city deployments. Similarly, small and medium OLTs like the EA5801 and EA5800-X2 are suitable for smaller-scale networks but are not directly related to the safe city use case.
