NEW QUESTION # 39
In IEEE 1588V2 frequency synchronization, all intermediate transmission devices must support the IEEE 1588V2 protocol.
- A. False
- B. True
Answer: B
Explanation:
In IEEE 1588V2 frequency synchronization, all intermediate transmission devices must support the IEEE 1588V2 protocol. This means that all devices that are involved in transmitting the synchronization signal, such as routers and switches, must be able to process and pass on the IEEE 1588V2 messages. If any device in the path of the synchronization signal does not support the IEEE 1588V2 protocol, it will not be able to process and forward the messages, and the overall synchronization will be affected.
NEW QUESTION # 40
Which of the following actions will trigger SgNB release by the MeNB?
- A. The UE inactivity timer on the NR side expires.
- B. The MeNB detects that the X2 link is abnormal.
- C. An inter-SgNB cell change occurs.
- D. The air interface link on the NR side is abnormal, and a UE reports SCG Failure Info to the eNodeB.
Answer: A,D
Explanation:
The UE inactivity timer on the NR side expiring and the air interface link on the NR side being abnormal, and a UE reporting SCG Failure Info to the eNodeB, can both trigger the MeNB to release the SgNB. Other actions, such as an inter-SgNB cell change or the MeNB detecting an abnormal X2 link, may also lead to SgNB release, but are not the trigger for it.

Answer: A
NEW QUESTION # 44
If the dock of a base station is locked and the base station fails to obtain clock source signals, which of the following clock states is the base station in?
- A. Holdover
- B. Locked
- C. Free running
- D. Fast tracking
Answer: A
Explanation:
The base station is in a Holdover state when the dock of a base station is locked and the base station fails to obtain clock source signals. Holdover is a state during which the base station uses the last known frequency and time information to maintain synchronization and clock accuracy. According to the Huawei official documentation, "when the clock source is lost, the base station enters the holdover state. In the holdover state, the base station uses the last known frequency and time information to maintain synchronization and clock accuracy. Holdover time is the duration for which the base station can maintain synchronization after the clock source is lost."
NEW QUESTION # 45
Which of the following MOs are involved in data reconfiguration using the MAE-Deployment?
- A. gNBDULogicNode
- B. gNodeBCUFunction
- C. gNodeBFuncrjon

Answer: C
NEW QUESTION # 46
Which of the following Information Is contained in a master Information block (MIB)?
- A. PDCCH ConfigSIB1
- B. dmrs-TypeA-Position
- C. Offset from PointA
- D. System frame number
Answer: A,B,D
Explanation:
In 5G NR, the master information block (MIB) is a control message that is transmitted by the base station on the Physical Broadcast Channel (PBCH). The MIB contains the following information:
1. System frame number: The MIB contains the system frame number (SFN) which is used to identify the current frame in the system.
2. PDCCH ConfigSIB1: The MIB contains the PDCCH (Physical Downlink Control Channel) configuration for the SIB1 (System Information Block 1) which is used to transmit system information to the UE.
3. dmrs-TypeA-Position: The MIB contains the position of the dmrs-TypeA (Diversity and Multiplexing Configuration Reference Signal) which is used to transmit a reference signal for demodulation and channel estimation.
NEW QUESTION # 47
The segmentation method is the most important method for isolating faults on the transport network. Different methods are used for different fault types.
- A. False
- B. True
Answer: B
Explanation:
The segmentation method is the most important method for isolating faults on the transport network. Different methods are used for different fault types, such as Optical Time Domain Reflectometry (OTDR) for fiber faults, Radio Frequency Interference Measurement (RFI) for radio interference, and Signal-to-Noise Ratio (SNR) for signal noise. By segmenting the network, faults can be easily identified and isolated.

NEW QUESTION # 50
Which of the following functions is provided by the network layer in the transport protocol stack?
- A. Addressing and route selection
- B. Physical medium access
- C. Transmission of binary data flows
- D. MAC forwarding
Answer: A
Explanation:
The network layer in the transport protocol stack provides functions such as addressing and route selection. It is responsible for finding the best route for data packets to travel from the source to the destination. It also provides logical addressing and packet routing. The network layer does not provide the transmission of binary data flows, MAC forwarding, or physical medium access.
