Which VMware storage technology provides hyperconverged, software-defined storage using direct-attached disks in ESXi hosts?
Answer: vSAN
vSAN is VMware's hyperconverged storage solution that aggregates local disks across ESXi hosts into a shared datastore for virtual machines.
What is the purpose of VMFS (Virtual Machine File System) in a vSphere environment?
Answer: To enable multiple ESXi hosts to read and write to shared storage simultaneously
VMFS is a clustered file system that allows multiple ESXi hosts to concurrently access the same shared storage block device, enabling features like vMotion and HA.
Which storage format should be used for virtual machine disks that require the highest performance with no snapshot overhead?
Answer: Eager Zeroed Thick (EZT)
Eager Zeroed Thick (EZT) disks are pre-allocated and zeroed at creation time, providing the highest I/O performance and are required for vSphere Fault Tolerance.
In vSphere, what is a 'snapshot' and what does it capture?
Answer: A point-in-time record of a VM's disk state, memory, and settings
A vSphere snapshot captures the state and data of a virtual machine at a specific point in time, including disk contents, memory state, and VM settings.
Which multipathing policy in vSphere sends I/O down a single active path and only switches to another if that path fails?
Answer: Most Recently Used (MRU)
Most Recently Used (MRU) policy uses the most recently active path for all I/O and only fails over to another path when the active path becomes unavailable.
What is the maximum size of a VMFS6 datastore volume in vSphere?
Answer: 64 TB
VMFS6 supports a maximum datastore volume size of 64 TB, and also introduces automatic space reclamation for thin-provisioned disks.
