Q24. Which of the following product models is faceplate ONU?

EG8240P

EG8080P

EG8145V5

EG8020P

The correct answer isEG8080P. Afaceplate ONUis a compact Optical Network Unit designed to be mounted on a wall or faceplate, typically used in Fiber-to-the-Room (FTTR) or Fiber-to-the-Desk (FTTD) scenarios.
TheEG8080Pis specifically designed for such applications, providing high-speed internet, voice, and video services in a small form factor.
Other options:
* EG8240P:A standard home gateway ONU, not a faceplate model.
* EG8145V5:A residential gateway ONU, not suitable for faceplate mounting.
* EG8020P:A business-class ONU, but not a faceplate model.

Q25. What are the challenges of e-government networks in the cloud era? (Multiple choice)

Network isolation and security

Growing Bandwidth Requirements

The business can be quickly opened and adjusted

Unified bearing of all government services

Q26. In the WDM model, the functional unit that completes the O-E-O conversion is?

OLA

MUX

DEMUX

OTU

Q27. Which interfaces does Huawei transmission equipment support? (Multiple choice)

STM-N

10GE

FC interface

Q28. 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.

TRUE

FALSE

Q29. Which is Huawei’s first transmission product in the highway section access solution?

OSN3500

OSN580

OSN1800

OSN7500

Q30. SDH basic transmission module is STM-4.

TRUE

FALSE

Q31. What are the advantages of the GPON bearing railway fiber-to-the-team solution? (Multiple choice)

Passive optical network, aggregation passive without power supply

Integrated access to solve voice, data, image

Multiple protection mechanisms are safe and reliable

P2P transmission mechanism, data transmission is more secure

Q32. Which of the following does Hardware redundancy of OLT products include?

Uplink Port

Power Board

Service Port

Main Control Board

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.

Q33. What is the minimum protection switching time of Link-layer Type B Switching?

1 min

3 s

3 min

50 ms

Type B Protectionin GPON networks refers to link-layer redundancy, where two independent fiber paths are used to connect an ONU to the OLT. In the event of a fiber failure, the system automatically switches to the backup path.
Theminimum protection switching timefor Type B protection is50 ms, ensuring minimal disruption to services. This rapid switching time is critical for maintaining high availability and reliability in mission- critical applications.

Q34. What is the maximum exchange capacity of the new brand OLT EA5800-X7 in the company?

7.2Tbit/s

3.6Tbit/s

1920Gbit/s

480Gbit/s

Q35. In the radio and television county and township solution, OSN 1800V products and OSN 1800II enhanced service boards cannot be universally used.

TRUE

FALSE

Q36. Which of the following suppliers does not support dual-plane solutions?

ALU

Huawei

H3C

ZTE

Q37. The main application scenarios of DC908 does not include: (Multiple Choice)

Complex city

Backbone network

DC point to point interconnection

Q38. Compared with the traditional LAN network, the all-optical campus network has a cost advantage. The cost saving is mainly the saving of the equipment cost, and the cost of wiring is similar to that of the traditional network.

TRUE

FALSE

Q39. A 2M optical port board is developed for the power relay protection scenario. The optical port is directly connected to the relay protection equipment. What equipment can be reduced to reduce the fault point?

Relay protection device

MUX/DMUX

Light cat

PCM

Q40. Huawei, NOKIA, ZTE, FiberHome, and Cisco are the main vendors of OLT.

True

False

The statement isFalse. While Huawei, NOKIA, ZTE, and FiberHome are indeed major vendors of Optical Line Terminals (OLTs),Ciscois not traditionally known as a primary OLT vendor. Cisco focuses more on enterprise networking solutions like routers, switches, and Wi-Fi systems rather than passive optical network (PON) equipment.
The leading OLT vendors in the market are:
* Huawei:Dominates the global OLT market with advanced GPON, XG(S)-PON, and Combo PON solutions.
* NOKIA:Offers robust PON solutions through its Alcatel-Lucent subsidiary.
* ZTE:Provides cost-effective PON solutions for both carriers and enterprises.
* FiberHome:Specializes in PON and fiber optic technologies.

Q41. Which of the following devices cannot be mounted in a 19-inch cabinet?

OSN 1800 I

OSN 9800 U32

OSN 1800 II

OSN 1800 V

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.
