- ACloning a powered-off VM
- BDeploying from a template with guest customizationCorrect answer
- CImporting an OVF file
- DCustomizing the guest OS during deploymentCorrect answer
Why this is the answer
Deploying with customization requires 'Allow customization' privilege. Customizing guest OS also needs that. Cloning uses 'Create from existing'; OVF import uses 'Import' privilege.
- Question 14Interactive
Read the code block; which state indicates the VM is ready for template conversion in content library?
- APowered offCorrect answer
- BPowered on with VMware Tools
- CSuspended
- DMaintenance mode
Why this is the answer
Templates in a content library must be created from powered-off VMs (or snapshots). The playbook notes that you convert a VM to a template, and it requires the VM to be powered off.
- Question 15Single Choice
What does vSphere Lifecycle Manager (vLCM) use to define the desired state of a cluster?
- AA single cluster imageCorrect answer
- BMultiple baselines
- CHost profiles
- DVirtual machine templates
Why this is the answer
vLCM uses a single image per cluster to define the exact desired state, replacing the multiple baselines of VUM.
- Question 16Multiple Select
Which two are steps in the vLCM remediation process?
- AHost enters maintenance modeCorrect answer
- BvCenter reboots
- CSoftware and firmware updates appliedCorrect answer
- DVirtual machines are migrated to another datacenter
Why this is the answer
During remediation, vLCM puts the host in maintenance mode, then applies updates. vCenter does not reboot, and VMs are not migrated to another datacenter (only to other hosts in the cluster).
- Question 17Interactive
Examine the code block; what is the purpose of the --rolling-update flag?
- AUpdates one host at a time to maintain cluster availabilityCorrect answer
- BUpdates all hosts simultaneously
- CSkips hosts that are non-compliant
- DPauses remediation at 50%
Why this is the answer
The rolling update flag ensures hosts are updated one at a time, preserving cluster capacity and availability during the maintenance window.
- Question 18Single Choice
Which interface should an administrator use to change the vCenter Server root password?
- AVAMI (port 5480)Correct answer
- BvSphere Client
- CESXi DCUI
- DvSphere Web Services API
Why this is the answer
VAMI (port 5480) is the dedicated appliance management interface for VCSA administrative tasks, including root password changes.
- Question 19Multiple Select
Which two settings are managed via host profiles rather than cluster-level configuration?
- AESXi advanced kernel parametersCorrect answer
- BvSphere DRS rules
- CVMkernel network interface configurationCorrect answer
- DvSphere HA admission control
Why this is the answer
Kernel parameters and VMkernel network config are host-level; DRS rules and HA admission control are cluster-level settings.
