VCP Virtual Machine Management & Lifecycle 2

Question 1

What is the primary role of VMware Tools installed inside a guest operating system?

Accepted Answer

To enhance VM performance and enable features such as graceful shutdown, time synchronization, and quiesced snapshots

Answer

To configure vSphere networking on the ESXi host

Answer

To manage vCenter Server inventory and user permissions

Answer

To monitor ESXi host hardware health and generate alerts

Question 2

Which virtual disk provisioning type allocates all disk space at creation time AND zeroes out all blocks before the VM first writes to them, providing the best I/O performance?

Accepted Answer

Thick Provisioned Eager Zeroed

Answer

Thin Provisioned

Answer

Thick Provisioned Lazy Zeroed

Answer

Raw Device Mapping (Physical)

Question 3

What is the purpose of a Raw Device Mapping (RDM) in a vSphere environment?

Accepted Answer

To allow a virtual machine direct access to a physical LUN on a SAN

Answer

To create a thin-provisioned virtual disk on an NFS datastore

Answer

To enable VM snapshots on datastores hosted on iSCSI targets

Answer

To configure a virtual machine's network adapter in passthrough mode

Question 4

Which file stores the configuration settings (CPU count, memory size, hardware devices) of a VMware virtual machine?

Accepted Answer

.vmx

Answer

.vmdk

Answer

.nvram

Answer

.vmss

Question 5

What is memory ballooning in vSphere, and how does it affect a virtual machine?

Accepted Answer

A memory reclamation technique where VMware Tools reclaims idle guest memory, potentially causing the guest to swap and degrading performance

Answer

A technique that expands VM memory allocation automatically, improving performance

Answer

A method that migrates a VM to a host with more available RAM without downtime

Answer

A feature that compresses duplicate memory pages across VMs to free physical RAM transparently

Question 6

Answer

E1000

Answer

E1000E

Answer

Flexible

Question 7

What information is stored in the .nvram file of a virtual machine?

Accepted Answer

The VM's BIOS or EFI firmware settings, including boot order

Answer

The VM's virtual disk data and snapshots

Answer

A memory dump captured during the last graceful shutdown

Answer

Performance counters and resource usage statistics for the VM
