What is meant by 'network scalability'?

• A. The capability to maintain network performance
• B. The ability to expand network capacity efficiently as demand increases
• C. A method for reducing network costs
• D. A strategy for optimizing existing resources

Answer: (B)

Network scalability refers to the ability to expand network capacity efficiently as demand increases. This concept is critical for businesses and organizations that anticipate growth in users, devices, or data traffic. When a network is scalable, it can accommodate these growing demands without compromising performance or requiring a complete overhaul of the existing infrastructure. This means that as more bandwidth is needed, or as additional devices are connected, the network can handle the increased load seamlessly. Scalability is often achieved through both hardware and software solutions that allow for easy additions or upgrades to the network resources, such as servers, switches, and routing equipment. The other options, while they may relate to aspects of network performance or management, do not encapsulate the core definition of scalability. Maintaining network performance is important, but it does not specifically address the expansion of capacity. Similarly, methods for reducing costs or optimizing resources might enhance network efficiency, but they do not directly define scalability.
