10+ Windows Vmware Administrator Interview Questions and Answers

There could be several reasons why I am not able to increase/decrease the VM resource.

• Insufficient permissions: I may not have the necessary administrative privileges to modify the VM resource settings.

• Resource limitations: The host server may have reached its resource capacity, preventing any further changes.

• VMware tools not installed: Without VMware tools installed on the guest OS, resource modifications may not be possible.

• Resource pool restrictions: The VM may be part of ...read more

The remote console for Dell servers is called iDRAC, for HP servers it is called iLO, and for Lenovo servers it is called IMM.

• Dell servers use iDRAC (Integrated Dell Remote Access Controller) for remote console access.

• HP servers use iLO (Integrated Lights-Out) for remote console access.

• Lenovo servers use IMM (Integrated Management Module) for remote console access.

I would troubleshoot the error by checking the WSUS logs and database, and then take appropriate action.

• Check the WSUS logs to identify the error

• Check the WSUS database for any issues

• Restart the WSUS service if necessary

• Run the WSUS cleanup wizard to remove any unnecessary updates

• Manually synchronize WSUS with Microsoft Update

• If all else fails, reinstall WSUS

To take a log from a physical host from a remote location, you can use remote access tools like SSH or remote desktop.

• Use SSH to remotely access the physical host and navigate to the log file location

• Copy the log file to your local machine using SCP or SFTP

• Alternatively, use remote desktop to connect to the physical host and access the log file directly

• Ensure you have the necessary credentials and network connectivity to establish remote access

Event ID 1074 is generated when the system is rebooted.

• Event Viewer can be used to view the event logs

• Event ID 1076 is generated when the system is shut down

• Event ID 6005 is generated when the system starts up

• Event ID 6006 is generated when the system shuts down properly

To perform Windows servers migration in a failover cluster, you can use tools like Storage Migration Service or manually move resources.

• Use Storage Migration Service to migrate data, shares, and security settings to new servers

• Ensure all cluster resources are online and healthy before starting the migration

• Consider using live migration for virtual machines to minimize downtime

• Update DNS records and network configurations to point to the new servers after migration

To replace a hard disk in a running server, follow these steps:

• Identify the faulty disk using disk management tools

• Prepare a new disk with the same specifications as the faulty one

• Physically replace the faulty disk with the new one

• Initialize the new disk and assign a drive letter

• Restore data from backup or rebuild RAID if necessary

Snapshot is a point-in-time copy of a VM, clone is an identical copy of a VM, template is a pre-configured VM image.

• Snapshot captures the current state of a VM, clone creates an exact duplicate of a VM, template is a pre-configured VM image for future use

• Standard vSwitch is a virtual switch that is created on a single ESXi host, dvSwitch is a distributed virtual switch that spans multiple ESXi hosts

• vMotion allows live migration of VMs between hosts without downtime

• P2V (Physic...read more

Server commissioning involves setting up a new server for use, while decommissioning involves retiring an old server.

• Commissioning: Install OS, configure network settings, install necessary software

• Decommissioning: Backup data, transfer services to new server, remove from network

• Document all steps taken for future reference

• Ensure proper communication with stakeholders throughout the process

DNZ records are used to map domain names to IP addresses for external-facing services.

• DNZ stands for DeMilitarized Zone

• DNZ records are used for external-facing services like web servers, email servers, etc.

• They map domain names to IP addresses

• DNZ records are used for security purposes to separate internal and external networks

FSMO roles are specialized domain controller tasks in Active Directory.

• There are 5 FSMO roles: Schema Master, Domain Naming Master, RID Master, PDC Emulator, and Infrastructure Master.

• Schema Master: responsible for updating the Active Directory schema.

• Domain Naming Master: responsible for adding or removing domains in the forest.

• RID Master: responsible for allocating RIDs to domain controllers.

• PDC Emulator: responsible for time synchronization and password changes.

• Infrastruct...read more

Patching of Windows servers involves applying updates and fixes to ensure security, stability, and performance.

• Regularly check for available updates from Microsoft.

• Create a patch management plan and schedule.

• Test patches in a non-production environment before deploying.

• Use automated tools like WSUS or SCCM for patch deployment.

• Monitor patch installation and verify successful completion.

• Document the patching process and maintain a patching log.

Vmotion is a feature in VMware that allows live migration of virtual machines between hosts without any downtime.

• Vmotion enables workload mobility and resource optimization

• It requires shared storage between the hosts

• During migration, the memory, CPU, and network state of the VM are transferred to the destination host

• Vmotion can be initiated manually or automatically based on resource utilization

• It helps in performing maintenance activities on the hosts without affecting the r...read more

ESXi can be patched using vSphere Update Manager or by manually downloading and installing patches.

• Use vSphere Update Manager to scan and remediate hosts

• Download patches from VMware website and install manually using ESXCLI or vSphere CLI

• Ensure compatibility of patches with ESXi version and hardware

• Reboot the host after patch installation

• Monitor patch installation progress and verify successful installation

vMotion is a feature in VMware that allows live migration of running virtual machines from one physical server to another without any downtime.

• Allows for workload balancing and maintenance without disrupting users

• Requires shared storage between the source and destination servers

• Ensures high availability and resource optimization

• Example: Moving a virtual machine from one host to another to free up resources for maintenance
