Which of the following statements about Network Slicing are correct? (Choose three.)

Network slicing is a key 5G architecture concept that enables the creation of multiple unique, logical, and virtualized end-to-end networks over a common physical infrastructure. Each slice is an isolated, independent network instance (A) tailored for a specific application or service. This customization allows for the allocation of specific network and computing resources (C) and the enforcement of unique Quality of Service (QoS) parameters, such as guaranteed bandwidth, latency, and reliability, to meet the distinct requirements of the service running on that slice (B). This approach allows a single physical network to efficiently support diverse services with vastly different performance needs, from massive IoT to ultra-reliable low-latency communications.

D. Network Slicing is a way to logically or virtually partition a network, not physically. The core principle is sharing a common physical infrastructure among multiple virtual networks.

Page 3, Section "What is network slicing?": "A network slice is an independent, end-to-end logical network that runs on a common physical infrastructure... Each slice is optimized to meet the specific Quality of Service (QoS) demands of a particular business purpose." This statement directly supports options A and B and refutes D.

Section II-A, "Network Slicing Concept," Paragraph 1: "Network slicing is a form of virtual networking architecture... It allows the creation of multiple virtual networks on top of a common physical infrastructure." This supports option A and clarifies why D is incorrect.

Section II-B, "Key Principles of Network Slicing," Paragraph 3 (Customization): This section explains that each slice can be configured with "specific resource allocations (e.g., bandwidth, processing, and storage)" and tailored for "specific QoS requirements," directly supporting options B and C.
