VCA vSphere Virtualization Fundamentals 3

Question 1

What is the VMkernel in VMware ESXi?

Accepted Answer

The core operating system layer of ESXi that manages hardware resources

Answer

The VMkernel is ESXi's core OS layer that directly controls hardware resources and provides scheduling, memory management, and I/O for virtual machines.

Question 2

Which vSphere concept describes isolating virtual machines into separate logical environments?

Accepted Answer

VM isolation

Answer

VM isolation ensures that virtual machines operate independently, so a crash or security breach in one VM does not directly affect other VMs on the same host.

Question 3

What is a VMware virtual appliance?

Accepted Answer

A pre-built VM image designed for a specific application or function

Answer

A virtual appliance is a pre-configured VM packaged with an OS and application, ready to deploy for a specific purpose like firewall, load balancer, or management tool.

Question 4

In vSphere, what does 'thin provisioning' mean for a virtual disk?

Accepted Answer

The disk only consumes storage space as data is actually written

Answer

Thin-provisioned disks start small and grow dynamically as data is written, making more efficient use of available storage compared to thick-provisioned disks.

Question 5

What is the vSphere Client used for?

Accepted Answer

Providing a web-based interface to manage vSphere environments

Answer

The vSphere Client is a web-based HTML5 interface used to manage ESXi hosts, virtual machines, datastores, and vCenter Server.
