How many virtual machines can a single ESXi host support?

A single ESXi host can support up to 1024 virtual machines, making this the correct answer. This capacity is significant for environments that require the consolidation of workloads or the hosting of numerous virtual machines on a single physical server. The ability to run such a high number of virtual machines on a single ESXi host is crucial for maximizing resource utilization and efficiency in data centers.

VMware has designed ESXi to manage resources effectively, allowing for optimized performance as it allocates CPU, memory, and storage to each virtual machine. This capability not only enables organizations to save hardware costs but also simplifies management processes. By supporting a high number of virtual machines, an organization can leverage virtualization technologies to improve scalability and flexibility in their IT infrastructure.

While the other options suggest lower numbers of supported virtual machines, they do not reflect the maximum capability of ESXi hosts, which has evolved to accommodate larger workloads in modern computing environments.
