What term describes the ability to route around broken servers on the Internet?

• A. DNS server
• B. Fault tolerant network
• C. Proxy server
• D. Bandwidth optimization

Answer: (B)

The ability to route around broken servers on the Internet is fault tolerance in networks. A fault-tolerant network is designed with redundancy so that if one server or link fails, traffic can be automatically rerouted through other paths, keeping services available. This resilience comes from multiple routes, backup servers, and dynamic routing that avoids failed components. Other concepts don’t capture this idea. A DNS server translates domain names to IP addresses, which helps you reach a site but doesn’t by itself ensure continued operation if servers fail. A proxy server acts as an intermediary between clients and servers, typically for caching or access control, not specifically for rerouting around failures. Bandwidth optimization focuses on making data transfer more efficient, not on maintaining availability when parts of the network fail.
