VCA vSphere Virtual Machine Management 1 — Questions and Answers
Question 1: What is vSphere vMotion used for?
- Migrating a running VM from one ESXi host to another with zero downtime (Correct answer)
- Creating a clone of a virtual machine on the same host
- Moving a VM's storage from one datastore to another
- Powering on a VM on a remote ESXi host
Correct answer: Migrating a running VM from one ESXi host to another with zero downtime
vMotion enables live migration of a running virtual machine between ESXi hosts without any downtime or interruption to the VM's operation.
Question 2: What is Storage vMotion in vSphere?
- Migrating a running VM between two ESXi hosts
- Moving a VM's disk files from one datastore to another while the VM is running (Correct answer)
- Replicating VM storage to a remote site
- Expanding a VM's virtual disk online
Correct answer: Moving a VM's disk files from one datastore to another while the VM is running
Storage vMotion migrates a virtual machine's disk files between datastores while the VM remains powered on and accessible to users.
Question 3: Which vSphere feature allows you to deploy multiple VMs quickly from a master template?
- VM snapshot
- VM clone
- VM template (Correct answer)
- VM linked clone
Correct answer: VM template
A VM template is a master image of a virtual machine that can be used to rapidly deploy multiple identical or similar VMs in a standardized configuration.
Question 4: What is the difference between a full clone and a linked clone in vSphere?
- Full clones share the parent VM's disk; linked clones are independent
- Full clones are independent copies; linked clones share the parent snapshot's disk (Correct answer)
- Full clones require vCenter; linked clones work on standalone ESXi
- Full clones are encrypted; linked clones are not
Correct answer: Full clones are independent copies; linked clones share the parent snapshot's disk
A full clone is a fully independent copy of a VM, while a linked clone shares a snapshot of the parent disk and only stores the differences, saving storage space.
Question 5: What vSphere feature monitors VM resource usage and generates performance charts?
- vSphere DRS
- vSphere Performance Charts in vCenter (Correct answer)
- VMware vRealize Operations
- vSphere vMotion
Correct answer: vSphere Performance Charts in vCenter
The vCenter Performance Charts feature provides real-time and historical graphs of CPU, memory, disk, and network usage for virtual machines and hosts.
Question 6: What happens to a VM's data when it is powered off and then deleted in vSphere?
- Data is moved to a trash folder and retained for 30 days
- All associated files including .vmdk and .vmx are removed from the datastore (Correct answer)
- Only the configuration file is deleted; disk files are retained
- The VM is suspended and moved to an archive datastore
Correct answer: All associated files including .vmdk and .vmx are removed from the datastore
Deleting a VM from disk in vSphere removes all associated files including the .vmdk disk files and .vmx configuration file from the datastore.
