                                        Correct Answer:<\/b> 2<\/b><\/p>\n

                                        Thick Provision Eager Zeroed allocates the full requested storage capacity for a virtual disk at creation time and completely zeroes out all blocks on the physical storage. Although creation takes longer because of the zeroing process, it delivers optimal write performance from the start and supports clustering features like Microsoft Failover Clustering. Unlike thin provisioning, space is fully reserved upfront, preventing unexpected out-of-space failures in production environments.<\/span><\/p>\n

                                          Correct Answer:<\/b> 1<\/b><\/p>\n

                                          Explanation:<\/b><\/p>\n

                                          Virtual Machine File System is a high-performance clustered file system designed specifically by VMware to store virtual machine files across shared block storage devices. It allows multiple ESXi hosts to read and write to the same storage repository simultaneously while preventing data corruption through advanced locking mechanisms. VMFS enables critical datacenter capabilities such as clustering, snapshots, and concurrent virtual machine migrations via vMotion.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
