Curious about Actual Huawei Certified Sales Associate (H19-315) Exam Questions?

Correct : A, B, C, D

The correct answer includes all options:Home-WiFi, IPTV, High-Speed Internet, and Telephone. FTTH (Fiber-to-the-Home) solutions are designed to deliver a wide range of services over a single fiber connection, leveraging the high bandwidth and low latency of optical networks.

Home-WiFi:Provides wireless internet access within the home using Wi-Fi routers connected to the ONU.

IPTV:Delivers high-quality video streaming services, including live TV, Video on Demand (VoD), and interactive features.

High-Speed Internet:Offers broadband connectivity for web browsing, online gaming, andother data-intensive applications.

Telephone:Supports Voice over IP (VoIP) services, enabling voice communication over the fiber network.

FTTH is a converged solution that integrates these services into a unified platform, simplifying network management and enhancing user experience.

ITU-T G.984.x Standards for GPON

Correct : A

The statement isTrue. TheHuawei EA5800 OLTplatform supportssoftware upgrades, which are critical for ensuringnetwork protectionand maintaining optimal performance. Software upgrades allow the OLT to incorporate new features, improve security, fix bugs, and enhance compatibility with emerging technologies.

Key aspects of software upgrades on the EA5800 include:

Security Enhancements:Regular updates patch vulnerabilities, protecting the network from cyber threats like DDoS attacks, unauthorized access, and malware.

Feature Expansion:New functionalities can be added to support evolving use cases, such as 5G backhaul, IoT integration, and advanced QoS (Quality of Service) mechanisms.

Performance Optimization:Upgrades often include improvements to system efficiency, reducing latency and increasing throughput.

Compliance:Ensures adherence to industry standards and regulatory requirements, such as ITU-T G.984.x for GPON and ITU-T G.988 for OMCI (ONT Management and Control Interface).

The ability to perform seamless software upgrades is a hallmark of Huawei's commitment to future-proofing its solutions, ensuring that networks remain robust and adaptable over time.

Correct : C

The correct answer isSlot 8. In theHuawei EA5800-X15 OLT, thecontrol boardis designed to be installed inSlot 8. The control board serves as the central processing unit of the OLT, managing system operations, traffic forwarding, and communication with other components.

Here's why Slot 8 is designated for the control board:

Centralized Location:Slot 8 is strategically positioned to ensure balanced power distribution and efficient heat dissipation, which are critical for maintaining system stability.

Redundancy Support:The EA5800-X15 supports dual control boards for high availability, with the second control board typically installed in Slot 7. This redundancy ensuresuninterrupted operation in case of a failure.

Compatibility:Only specific slots are compatible with control boards due to their unique hardware and connectivity requirements.

Slots 9 and 10 are typically reserved for service boards or uplink modules, while Slot 7 may house a secondary control board.

Correct : B, D

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.

ITU-T G.984.x Standards for GPON

Correct : B, D

The correct answers areClass B+andClass C+. These optical module classes are widely used in commercial GPON deployments due to their balance of performance, cost, and reliability.

Class B+:Supports transmission distances up to20 kmand is commonly used in urban and suburban areas. It provides sufficient power budget for most residential and small business applications.

Class C+:Supports longer distances (up to40 km) and higher split ratios, making it idealfor rural or remote areas where extended reach is required.

Other options:

Class D:Not a standard classification for GPON optical modules.

Class E and F:These classifications do not exist in current GPON standards.

The choice between Class B+ and Class C+ depends on the specific deployment scenario, including distance, split ratio, and environmental conditions.
