Which statement is true about configuring a server group?

A server group can indeed contain more than one server, which allows for better distribution of load and increased redundancy. This capability is fundamental in network design, especially in scenarios where high availability and reliability are crucial. With multiple servers in a group, if one server faces issues, the others can continue to manage incoming requests, ensuring that services remain uninterrupted.

The flexibility to include multiple servers enhances scalability and performance, which is key for handling varying levels of demand in network traffic. In contrast, a server group limited to a single server would create a single point of failure and reduce the overall resilience of the system. Furthermore, having a diverse set of server types is not a requirement for the formation of a server group, although it can be beneficial for specific applications or configurations, but it does not define the structure of a server group. Thus, the ability of a server group to include more than one server makes it an essential concept in ensuring effective network operations.
