During the scenario of DCI, the most important driving force for self-built transmission networks is:
Correct Answer: B
Question 37
Which board in the OSN 9800 device supports the FC1600 service? (Multiple choice)
Correct Answer: B,C,D
Question 38
What's the minimum protection switching time of Link-layer Type B Switching?
Correct Answer: A
The minimum protection switching time forLink-layer Type B Switchingin GPON is50ms. Type B protection involves protecting the fiber link between the OLT and the splitter by providing redundant fibers. In the event of a fiber failure, the system switches to the backup fiber within 50ms to ensure minimal service disruption. This fast switching time is critical for maintaining high availability and reliability in GPON networks. * 3s, 3min, 1min:These times are far too long for protection switching in modern optical networks, which require near-instantaneous recovery to meet SLA (Service Level Agreement) requirements.
Question 39
Which of the following is NOT an enterprise production network's requirement on optical transmission?
Correct Answer: B
The correct answer isMore complex. Enterprise production networks prioritize simplicity, intelligence, and security in optical transmission, rather than unnecessary complexity. Here's an analysis of each option: * A. More intelligent:Enterprises increasingly demand intelligent networks that leverage AI and automation for tasks like fault detection, performance optimization, and service provisioning. * B. More complex:Complexity is generally undesirable in enterprise networks, as it increases operational overhead, raises costs, and introduces potential points of failure. Modern solutions aim to simplify network architecture while enhancing functionality. * C. Simpler:Simplicity is a key requirement for enterprise networks, enabling easier deployment, management, and troubleshooting. Solutions like converged platforms (e.g., MS-OTN) and automated tools (e.g., NCE-T) help achieve this goal. * D. More secure:Security is critical for protecting sensitive data and ensuring compliance with regulations. Features like hard pipe isolation, encryption, and access control are essential for enterprise networks. By focusing on intelligence, simplicity, and security, optical transmission solutions can better meet the evolving needs of enterprise production networks.
