What is the primary purpose of ESXi Quick Boot?

The primary purpose of ESXi Quick Boot is to reduce remediation time during patch or upgrade operations. Quick Boot allows the ESXi hypervisor to skip the complete hardware initialization process that typically occurs during a host reboot. Instead of going through a full POST (Power-On Self-Test) sequence and hardware initialization, Quick Boot leverages previously initialized state information to bring the system back online more quickly.

This is particularly beneficial in environments where minimizing downtime is critical. During patching or updates, Quick Boot enables faster return to operational status, allowing for more efficient maintenance windows and reduced impact on running workloads. By streamlining the boot process, it effectively enhances the overall efficiency of managing the ESXi host lifecycle.

While other options may relate to different aspects of system performance or management, they do not accurately capture the specific functionality and advantages that Quick Boot provides in the context of operational efficiency during updates and patches.
