NEW QUESTION # 62
The EMR8 is 5U wide, which takes 2 slots.
- A. False
- B. True
Answer: A
Explanation:
The statement isFalse. TheEMR8board isnot 5U wideand does not occupy2 slots. Instead, the EMR8 is a compact boarddesigned to fit into a single slot within the chassis.
Here's a breakdown of the EMR8 board:
* Form Factor:The EMR8 is a single-slot board, making it highly space-efficient.
* Functionality:It provides advanced multiplexing and routing capabilities for optical networks, supporting services like OTN, SDH, and Ethernet.
* Chassis Compatibility:Designed to work seamlessly with Huawei's optical transport platforms, such as the OSN series.
The confusion may arise from other boards or components that require multiple slots, but the EMR8 itself is a single-slot device.
NEW QUESTION # 63
There are many new highway lines in my country, and the network structure is complicated. ASON technology can greatly improve the overall reliability of the network.
- A. FALSE
- B. TRUE
Answer: B
NEW QUESTION # 64
DCI evolves to mesh, simplified, and intelligent network.
- A. False
- B. True
Answer: B
Explanation:
The evolution ofData Center Interconnect (DCI)networks has been driven by the increasing demand for high-speed, reliable, and scalable connectivity between data centers. Modern DCI networks are evolving toward the following characteristics:
* Mesh Architecture:Enables multiple redundant paths between data centers, improving resilience and fault tolerance.
* Simplified Deployment:Leveraging plug-and-play devices and automated provisioning reduces complexity and speeds up deployment.
* Intelligent Management:AI-driven analytics and automation optimize network performance, predict faults, and streamline operations.
Huawei'sOptiXtrans DC908exemplifies these trends, offering high capacity, low latency, and intelligent O&M capabilities.
Thus, the statement is correct.

NEW QUESTION # 69
Which of the following scenarios could use NCE-FAN Lite products?
- A. The management capacity is more than 5000 equivalent NEs.
- B. The management capacity is less than 1000 equivalent NEs.
- C. The management capacity is more than 4000 equivalent NEs.
- D. The management capacity is more than 3000 equivalent NEs.
Answer: B
Explanation:
The correct answer isThe management capacity is less than 1000 equivalent NEs.NCE-FAN Liteis a lightweight version of Huawei's Network Cloud Engine for Fixed Access Networks (NCE-FAN), designed for small to medium-sized deployments.
Key characteristics of NCE-FAN Lite include:
* Scalability:Suitable for managing up to1000 equivalent NEs (Network Elements), making it ideal for smaller networks like enterprise campuses or regional ISPs.
* Cost Efficiency:Offers a simplified feature set compared to the full NCE-FAN, reducing costs for organizations with limited management needs.
* Ease of Deployment:Simplifies network operations with centralized monitoring, configuration, and troubleshooting capabilities.
Options A, C, and D refer to larger-scale deployments that exceed the capacity of NCE-FAN Lite. For such scenarios, the full version of NCE-FAN or other advanced management platforms would be required.
