Do you know about 5G Technology?

Explanation
The statement "All of the above" is the correct answer because it accurately summarizes the true aspects of 5G technology. 5G delivers higher multi-Gbps peak data speeds, providing faster and more efficient communication. It also offers more reliability, ensuring a stable and consistent connection. Additionally, 5G has a massive network capacity, allowing for a larger number of devices to be connected simultaneously without compromising performance. Therefore, all three statements are true regarding 5G technology.

Explanation
The "G" in 5G stands for "Generation." This refers to the fifth generation of wireless technology. Each new generation represents a significant advancement in terms of speed, capacity, and connectivity compared to the previous generation. Therefore, the correct answer is Generation.

Explanation
5G mobile service was launched in the US on April 3, 2019.

Explanation
South Korea is the correct answer because it was the first country to launch 5G services. South Korea rolled out its 5G network in April 2019, ahead of other countries. This launch allowed South Korean consumers to experience faster internet speeds and enhanced connectivity through 5G technology.

Explanation
The expected peak data rate of 5G is up to 20 Gbit/s. This means that 5G networks have the capability to provide data speeds of up to 20 gigabits per second. This high data rate allows for faster downloads, smoother streaming, and improved overall network performance. With this level of speed, 5G has the potential to revolutionize various industries and enable technologies such as autonomous vehicles, virtual reality, and the Internet of Things.

Explanation
The correct answer is gNB. In the context of 5G technology, gNB stands for "Next Generation Node B" or "Next Generation Base Station." It is the base station used in the 5G network architecture. The gNB is responsible for transmitting and receiving wireless signals to and from user devices, providing improved speed, capacity, and latency compared to previous generations.

Explanation
Bandwidth refers to the maximum amount of data that can be transmitted over a network or communication channel. It represents the capacity of the network to handle data transmission. Therefore, the term "capacity" can be used synonymously for bandwidth, as both refer to the ability to handle data at higher speeds. "Speed" and "connection" are not appropriate synonyms for bandwidth as they refer to the rate at which data is transmitted and the establishment of a link between devices, respectively.

Explanation
Both Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) can integrate with 5G infrastructure. SDN is a technology that separates the network control plane from the data plane, allowing for more flexible and programmable networks. NFV, on the other hand, virtualizes network functions such as firewalls and load balancers, enabling them to run on standard hardware. By integrating SDN and NFV with 5G, operators can achieve greater network agility, scalability, and cost-efficiency.

Explanation
All of the above options (traffic restoration, SLA, and policy) are common functions used to provide Quality of Service (QoS) in the management plane. Traffic restoration involves restoring network traffic in case of failures or disruptions. SLA (Service Level Agreement) defines the agreed-upon level of service between a service provider and a customer. Policies are rules or guidelines that dictate how network resources should be allocated and managed to ensure QoS. Therefore, all three options contribute to QoS in the management plane.

Explanation
5G technology is being used in various areas including enhanced mobile broadband, mission-critical communications, and massive IoT. Enhanced mobile broadband refers to the high-speed internet access provided by 5G networks, allowing for faster downloads and smoother streaming. Mission-critical communications involve the use of 5G for critical applications such as emergency services and public safety, where reliable and low-latency communication is essential. Massive IoT refers to the ability of 5G to connect a large number of devices and enable efficient communication among them. Therefore, the correct answer is "All of the above" as 5G is being utilized in all these areas.
