An administrator purchases a new server, which contains only one Xeon processor. This server is also known as a:

Load balancing server describes a server's network role or function, not its processor or core architecture.

Intel Xeon processors integrate multiple processing cores on a single chip die, meaning one physical Xeon processor makes the entire server a multicore server. The classification 'multicore' refers to the core count per processor package, not the number of sockets. A single Xeon can contain anywhere from 4 to over 60 cores depending on the product generation.

Redundant server describes a failover or high-availability configuration, not a processor type or count.

Single-core describes a processor with only one processing core; all Intel Xeon processors ship with multiple cores by design.
