Demo Questions
Question 1
In NSA networking, which of the following modes is used to anchor 5G NR?
- OGSM
- WCDMA
- CDMA
- LTE
Correct answer: D
Explanation:
The non-standalone (NSA) mode of 5G NR refers to an option of 5G NR deployment that depends on the control plane of an existing 4G LTE network for control functions, while 5G NR is exclusively focused on the user plane.[7][8] This is reported to speed up 5G adoption, however some operators and vendors have criticized prioritizing the introduction of 5G NR NSA on the grounds that it could hinder the implementation of the standalone mode of the network The non-standalone (NSA) mode of 5G NR refers to an option of 5G NR deployment that depends on the control plane of an existing 4G LTE network for control functions, while 5G NR is exclusively focused on the user plane.[7][8] This is reported to speed up 5G adoption, however some operators and vendors have criticized prioritizing the introduction of 5G NR NSA on the grounds that it could hinder the implementation of the standalone mode of the network
Question 2
Which of the following devices is used to implement service slicing on the 5G RAN side?
- Antenna
- BBU
- AAU
- RRU
Correct answer: B
Question 3
E2E network device update is required for the evolution from 5G NSA networking to SA networking.
- True
- False
Correct answer: B
Question 4
5G wireless network cloudification can significantly improve the user rate.
- True
- False
Correct answer: A
Question 5
C-band is the most popular frequency band for 5G network deployment. However, there is an imbalance between uplink and downlink coverage -- how much does this imbalance approximately amount to?
- 5dB
- 3dB
- 12dB
- 20dB
Correct answer: D
Question 6
F-OFDM over the NR air interface uses flexible subcarrier spacing to meet the requirements of different 5G service scenarios. Which of the following types of subcarrier spacing is not supported by Sub6G?
- 120KHz
- 15KHz
- 60KHZ
- 30KHz
Correct answer: A
Explanation:
Question 7
The mmWave range is new for NR. It supports the largest bandwidth in a cell but has poor coverage capabilities. It requires high performance from RF components and generally applies only to line of sight (LOS) coverage.
- True
- False
Correct answer: B
Question 8
Which of the following statements about the NR slot structure are correct?
- Downlink slots can only be used to transmit downlink data.
- Downlink self-contained slots can be used to transmit uplink data and SRSs.
- The number of symbols in one slot is fixed to 14 regardless of the subcarrier spacing configuration.
- The symbols in a slot can be classified as downlink, uplink, or flexible.
Correct answer: C
Question 9
5G inherits the frame structure of 4G, but the slot length can be adjusted based on different SCSs.
Which of the following is not a 5G slot length?
- 0.5ms
- 10ms
- 0.25ms
- 1ms
Correct answer: B
Question 10
Which of the following parameters is related to the frequency-domain position of PBCH DMRSs?
- Cell ID
- PCI
- SI-RNTI
- Bandwidth
Correct answer: A
Explanation:
The physical location (Resource Elements) of PBCH DMRS is determined as below. As you see here, the location shifts in frequency domain according to Physical Cell ID.
