VCP Storage Management & Availability

Question 1

Which VMware storage technology provides hyperconverged, software-defined storage using direct-attached disks in ESXi hosts?

Accepted Answer

vSAN

Answer

vSAN is VMware's hyperconverged storage solution that aggregates local disks across ESXi hosts into a shared datastore for virtual machines.

Question 2

What is the purpose of VMFS (Virtual Machine File System) in a vSphere environment?

Accepted Answer

To enable multiple ESXi hosts to read and write to shared storage simultaneously

Answer

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.

Question 3

Which storage format should be used for virtual machine disks that require the highest performance with no snapshot overhead?

Accepted Answer

Eager Zeroed Thick (EZT)

Answer

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.

Question 4

In vSphere, what is a 'snapshot' and what does it capture?

Accepted Answer

A point-in-time record of a VM's disk state, memory, and settings

Answer

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.

Question 5

Which multipathing policy in vSphere sends I/O down a single active path and only switches to another if that path fails?

Accepted Answer

Most Recently Used (MRU)

Answer

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.
