Final answer:
Failover clustering feature is supported by operating systems such as various editions of Windows Server and certain versions of Linux that are tailored for server or enterprise usage.
Step-by-step explanation:
The failover clustering feature is supported by several operating systems. These operating systems are typically server editions, as failover clustering is designed for systems that require high availability. One of the most common examples of such an operating system is Windows Server, with versions starting from Windows Server 2003 including failover clustering support. Other operating systems such as certain editions of Linux also provide support for failover clustering through different software packages like Pacemaker. Keep in mind that not all versions of an OS may support clustering - it's generally limited to server or enterprise editions which are designed for such advanced computing environments.
