What technology ensures that web services remain operational across different geographical locations?

The option indicating "geographically dispersed service" is the most appropriate choice for ensuring that web services remain operational across different geographical locations. This technology involves the distribution of services and resources across multiple data centers or cloud regions, allowing for redundancy and resilience. If one geographical location experiences an outage or other issues, services can still be accessed from other locations, ensuring continuous availability and minimizing downtime.

By implementing a geographically dispersed service architecture, organizations can enhance their disaster recovery capabilities and improve performance for users located in different parts of the world. This approach is particularly beneficial in cloud environments where resources can be dynamically allocated and managed.

While a web farm involves multiple servers working together to handle traffic, it does not specifically address the aspect of geographical distribution. A load balancer helps distribute network or application traffic across multiple servers but does not inherently create geographical redundancy. Network segmentation refers to dividing a network into segments for improved performance and security, but it doesn’t relate to geographical distribution either.
