Pass the Huawei HCPA-Transmission&Access H19-315 Questions and answers with CertsForce

TheMS-OTN (Multi-Service Optical Transport Network)is specifically designed to support multiple types of services and protocols, including:

OTN (Optical Transport Network):Provides high-capacity transport for long-haul andmetro networks.

SDH (Synchronous Digital Hierarchy):Supports legacy TDM-based services.

PKT (Packet):Enables packet-based services such as Ethernet and IP/MPLS.

MS-OTN integrates these technologies into a single platform, allowing service providers to converge multiple services onto a unified infrastructure. This flexibility makes MS-OTN ideal for modernizing existing networks while supporting future growth.

The statement that MS-OTN "can't support OTN, SDH, and PKT" is therefore incorrect.

TheOptiXtrans E9624is a high-end optical transport platform designed for core networks. Itsmaximum cross-connect capacity is 24 Tbps per subrack, not 2.4 Tbps as stated in the question. This makes it one of the most powerful systems in Huawei's optical transport portfolio, capable of handling massive traffic volumes in backbone and metro-core networks.

The confusion may arise from other models in the series, such as the OptiXtrans E9605, which has a lower capacity. However, the E9624 is specifically engineered for ultra-high-capacity scenarios.

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.

TheOptiXtrans E9600 seriesis part of Huawei's advanced optical transmission portfolio, designed for high-capacity and long-haul transport networks. The series includes the following models:

OptiXtrans E9624:High-end model with a maximum cross-connect capacity of 24 Tbps per subrack, suitable for core networks.

OptiXtrans E9612:Mid-range model with a maximum cross-connect capacity of 12 Tbps per subrack, ideal for metro and regional networks.

OptiXtrans E9605:Compact model with a smaller footprint, designed for edge and access networks.

These models cater to different network requirements, from core to edge deployments, ensuring scalability and flexibility.

The statement isTrue. TheOptiXtrans DC908is primarily designed forbackbone long-distance networks, where high capacity, low latency, and reliability are critical.

Here’s why the DC908 is well-suited for backbone networks:

High Capacity:The DC908 supports up to38.4 Tbps per fiber pair, making it ideal for transporting massive volumes of data over long distances.

Long-Distance Transmission:Leveraging advanced technologies likeEDFA (Erbium-Doped Fiber Amplifier)andRaman amplification, the DC908 can transmit data over distances exceeding1,000 kmwithout regeneration.

Low Latency:Designed for ultra-low latency, the DC908 ensures minimal delay for mission-critical applications like cloud computing, AI, and big data analytics.

Reliability:Features likeoptical protection switchingandhard pipe isolationensure uninterrupted service even in the event of failures.

While the DC908 can also be used for shorter distances (e.g., metro or regional networks), its primary application is inlong-haul backbone networksthat connect major cities, data centers, and international gateways.
