NEW QUESTION # 10
5G wireless network cloudification can significantly improve the user rate.
- A. True
- B. False
Answer: A
Explanation:
Cloudification of 5G wireless networks can significantly improve the user rate. Cloudification refers to the process of virtualizing the functions of a network and running them on commodity hardware in a data center, rather than on dedicated hardware in the network itself. In the case of 5G wireless networks, this can be achieved by virtualizing the Base Station (gNB) functions and running them on a cloud platform. This allows for more efficient use of resources and better scalability, which can result in an improved user rate.
Additionally, Cloud-RAN (C-RAN) architecture, which is a cloud-based centralization of the baseband processing functions can also be used to improve the user rate by reducing the number of active base stations required in a given area, and also by allowing for more efficient management of resources and more flexible deployment of services.
However, it's worth noting that the improvement of the user rate is not only limited to cloudification, but it's also related to many other factors such as network design, optimization, and management.

At which layer is downlink data split implemented over the NR air interface in the NSA Option 3x architecture?
- A. MAC layer
- B. Physical layer
- C. PDCP layer
- D. RLC layer
Answer: A
Explanation:
Downlink data split over the NR air interface in the NSA Option 3x architecture is implemented at the medium access control (MAC) layer. The MAC layer is responsible for the management of data transmission over the air interface, including segmentation and reassembly of data packets, scheduling of transmission resources, and error correction. The other layers (RLC, PDCP, and physical) are not involved in the implementation of downlink data split.

In the Non-Stand-Alone (NSA) Option 3x architecture, the control plane functions are handled by the 4G LTE network (EPC), while the user plane functions are handled by the 5G NR network. Data split is a technique that allows to split the user plane data between the 4G LTE and 5G NR networks.
The MAC (Medium Access Control) layer is responsible for controlling the access to the shared wireless medium, and it is where the downlink data split is implemented. In this architecture, the MAC layer in the 5G NR network receives the downlink data from the 4G LTE network and sends it to the physical layer for transmission.

NEW QUESTION # 25
E2E network device update is required for the evolution from 5G NSA networking to SA networking.
- A. True
- B. False
Answer: A
Explanation:
End-to-end (E2E) network device update is required for the evolution from 5G Non-Stand-Alone (NSA) networking to Stand-Alone (SA) networking. In 5G NSA networking, the control plane functions are handled by the 4G LTE network, while the user plane functions are handled by the 5G NR network. In contrast, in 5G SA networking, the control plane and user plane functions are handled by the 5G NR network alone. So, to evolve from 5G NSA to 5G SA, all the network devices including Radio Access Network (RAN), Core Network (CN) and Transport Network (TN) need to be updated with 5G SA capable software and hardware.
It is important to note that 5G SA provides more flexibility, control and autonomy for network operation and management, However, it also requires a higher level of complexity and more resources to operate.

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?
- A. 60KHZ
- B. 120KHz
- C. 15KHz
- D. 30KHz
Answer: B
Explanation:
F-OFDM (Filtered Orthogonal Frequency Division Multiplexing) over the NR air interface uses flexible subcarrier spacing to meet the requirements of different 5G service scenarios. F-OFDM is a 5G physical layer waveform that is designed to provide high spectral efficiency, low complexity and low latency. It uses a flexible subcarrier spacing, which can be adjusted to meet the requirements of different 5G services. The subcarrier spacing can be 15KHz, 30KHz, 60KHz, or 120KHz.
Sub-6GHz 5G networks are designed to provide wide-area coverage and support high data rate services such as mobile broadband, IoT, and critical communications. Sub-6GHz band is mainly used for 5G deployment in rural areas, and in-building coverage.
Therefore, the subcarrier spacing that is not supported by Sub-6GHz is 120KHz. So the correct answer is A. 120KHz. It's worth noting that each subcarrier spacing has its own advantages and disadvantages. 120KHz spacing is mainly used for low mobility services such as fixed wireless access, while 15KHz spacing is mainly used for high mobility services such as mobile broadband.
