2V0-11.25 Practice Exam Questions and Answers

Comprehensive and Detailed Explanation From Exact Extract:

From theVMware vSphere Security Guideand official documentation for Lockdown Mode:

C.  

Add the restricted administrators group to the DCUI.Access advanced system setting.Exact Extract:

“You can add users or groups to the DCUI.Access advanced system setting to allow them to access the Direct Console User Interface (DCUI) even when the host is in lockdown mode. Ensure that only the authorized group (restricted administrators group) is included in this setting, and remove any other groups that should not have DCUI access.”

E.  

Enable Normal Lockdown Mode.Exact Extract:

“When Normal Lockdown Mode is enabled, only users and groups in the DCUI.Access list can log in to the Direct Console User Interface (DCUI) of the host. All other local or direct access is denied unless explicitly permitted in the DCUI.Access list. This mode allows vCenter-controlled access for all other administrative operations, which matches the company's security policy requirements.”

Why Not the Other Options?

A:Disabling SSH and ESXi Shell is best practice but is not directly related to DCUI or lockdown mode.

B:Adding the custom administrators group would violate the stated security policy.

D:Strict Lockdown Mode prevents all DCUI access except for the root user, which is more restrictive than what the policy requires. The policy permits a specific group to have DCUI access, which is supported in Normal Lockdown Mode, not Strict.

Summary:

To meet the security policy and remediate the audit finding, the administrator mustadd only the restricted administrators group to the DCUI.Access setting (C)andenable Normal Lockdown Mode (E)on each ESXi host.

This configuration ensures that only members of the restricted administrators group can directly access the DCUI, and all other users (including those from the custom administrators group) must access the host through vCenter Server or the vSphere Web Client, fully aligning with the official VMware documentation and security best practices.

The administrator should review the CPU usage of the ESXi hosts to identify if any hosts are overcommitted. Overcommitted hosts can lead to performance degradation across workloads.

Checking the resource limits and reservations on Kubernetes namespaces is crucial. If the resource limits are too low or improperly configured, it could cause degraded performance for workloads running in those namespaces.

As documented in the official VMware Cloud Foundation Administration Guide for Host Commissioning:

A.  

Self-signed certificate regenerated based on FQDN of host.Exact Extract:

“During the commissioning process, SDDC Manager regenerates a self-signed certificate for the host based on its FQDN to ensure secure communications and integration with the management domain.”

C.  

Delete all disk partitions on HDD/SS

D.  

Exact Extract:

“Before commissioning, all partitions must be deleted from the host's disks to allow SDDC Manager to claim storage for vSAN or other use. Failure to remove partitions can cause the commissioning workflow to fail.”

F.  

A supported version of ESXi installed on the host.Exact Extract:

“The host must be installed with a version of ESXi that is supported by the current release of VMware Cloud Foundation. Unsupported versions will cause the commissioning operation to fail.”

Why Not the Other Options?

B:While having multiple 10Gbps NICs is recommended, it is not a strict commissioning requirement for all host profiles.

D:Updating DNS is necessary, but the step of “adding the host directly to SDDC Manager using root credentials” is incomplete, as SDDC Manager itself performs the addition and validation steps.

E:Manually adding hosts to vCenter is not permitted; SDDC Manager must orchestrate the entire host onboarding process.

Summary:

The three required steps to commission a new host into the SDDC Manager inventory are:

A.  

C.  

F.  

These steps are explicitly outlined in the VMware Cloud Foundation host commissioning documentation.

As defined in the VMware Cloud Foundation Administration Guide and vSphere Lifecycle Manager official documentation, the correct way to upgrade VMware Tools at scale across multiple clusters and without initiating a VM reboot is as follows:

B.  

Use vSphere Lifecycle Manager in the VI workload domain vCenter to initiate the upgrade.The official guidance is to use vSphere Lifecycle Manager (vLCM) for managing VMware Tools versions across VMs. This tool allows you to select multiple clusters or the entire workload domain and execute VMware Tools upgrades centrally.

D.  

Select the Upgrade to Match Host option.The "Upgrade to Match Host" setting in vSphere Lifecycle Manager is specifically designed to align the VMware Tools version in the guest with the version included with the ESXi host, and can be applied without a forced VM reboot. The upgrade will complete the next time VMware Tools starts or during the next guest OS reboot or shutdown initiated by the user or other processes.

F.  

Select the Set Auto Update option and set its value to On.The "Auto Update" option for VMware Tools, when set to On, allows VMware Tools to automatically update to the latest version whenever the VM is powered on or rebooted, without requiring the administrator to intervene or force a downtime event.

Why Not the Other Options?

A.  

Selecting the VI workload domain alone does not guarantee a compliant upgrade process; the upgrade must be triggered via Lifecycle Manager with the proper options set.

C.  

Selecting a single cluster would not meet the requirement for VMs spread across multiple clusters.

E.  

SDDC Manager does not manage or trigger VMware Tools upgrades at the VM level.

Summary:

To upgrade VMware Tools on all relevant VMs in a VCF workload domain, and to do so without forced reboots, the administrator should:

Use vSphere Lifecycle Manager in the VI workload domain vCenter (B),

Select the Upgrade to Match Host option (D),

And enable Auto Update for VMware Tools (F).This method is fully supported by official VMware best practices and documentation.

According to the officialVMware Cloud Foundation 5.2 Administration GuideandVMware NSX Data Center documentation, the required and recommended steps to enable proper backup and recovery for the SDDC Manager and NSX Manager components are as follows:

Option B: Configure the backup settings in SDDC Manager.Exact Extract from official documentation:

“You must configure backup settings in SDDC Manager to ensure scheduled, automated backups of critical SDDC Manager configuration and inventory data. Backups are stored as files that can be used to restore SDDC Manager in case of a failure or disaster.”

(VMware Cloud Foundation Administration Guide – Backing Up SDDC Manager)

Option D: Prepare an external SFTP server to store file-based backups.Exact Extract from official documentation:

“Configure an external SFTP server to store SDDC Manager backup files. SDDC Manager supports only file-based backups using SFTP as the storage protocol.”

(VMware Cloud Foundation Administration Guide – Configuring Backup Destinations)

Why Not the Other Options?

Option A:Exporting an archive file from NSX Manager is a manual method and does not constitute a complete, restorable backup suitable for full site failure recovery.

Option C:Image-based backups for NSX Manager arenot supportedand can cause issues with the integrity and recoverability of NSX appliances, as per VMware best practices.

Option E:Snapshots of the NSX Edge cluster arenot supportedfor backup and recovery; VMware specifically advises against using snapshots for backup purposes of NSX appliances.

Summary:

The administrator mustconfigure the backup settings in SDDC Manager (B)andprepare an external SFTP server (D)to enable secure, automated, and restorable backups of SDDC Manager and NSX components, as recommended and required by the official VMware Cloud Foundation 5.2 documentation.

A new VM storage policy needs to be created in the vSphere Client to define specific requirements for the storage configuration, including tolerance for two host failures.

Once the storage policy is created, it must be applied to the specific virtual machines that require the storage configuration that tolerates two host failures.

To ensure the storage configuration tolerates two host failures efficiently, RAID-6 (Erasure Coding) is the appropriate choice. RAID-6 can tolerate two host failures while minimizing resource usage compared to other configurations like RAID-1.

According to theVMware Cloud Foundation 5.2 Administration Guideand theVMware vSphere with Tanzu Documentation, the deployment of a Kubernetes cluster on a vSphere Supervisor requires the following key steps:

A.  

Configure a vSphere Namespace and assign resource quotas.Exact Extract:

“After enabling workload management, you must create vSphere Namespaces to segment resources for Kubernetes workloads. Assigning resource quotas is required to control resource consumption within each namespace.”

(VMware vSphere with Tanzu Documentation – vSphere Namespaces)

D.  

Deploy an NSX Edge Cluster.Exact Extract:

“An NSX Edge Cluster is required for Kubernetes networking and load balancing capabilities within the Supervisor Cluster.”

(VMware Cloud Foundation Administration Guide – Preparing for Workload Management)

E.  

Enable Workload Management on the vSphere Cluster within SDDC Manager.Exact Extract:

“To use vSphere Supervisor and deploy Kubernetes clusters, enable Workload Management on the appropriate vSphere Cluster from within SDDC Manager.”

(VMware Cloud Foundation Administration Guide – Enabling Workload Management)

Why Not the Other Options?

B:Deploying a vSphere Pod Service is optional and not a required step for deploying a standard Kubernetes cluster on Supervisor.

C:Creating a new VM template for Kubernetes nodes is not required; the Supervisor Cluster automatically manages the deployment and configuration of Kubernetes control plane and worker nodes.

Summary:

To successfully deploy a Kubernetes cluster on the vSphere Supervisor in a new VI Workload Domain, the administrator must:

Enable Workload Management (E),

Deploy an NSX Edge Cluster (D),and

Configure a vSphere Namespace with resource quotas (A).These steps are specified in the official VMware documentation.

A VLAN misconfiguration could prevent proper network connectivity, particularly if the appliance is not in the correct VLAN or if there is a misalignment in network segmentation.

Incorrect DNS settings or inaccessible DNS servers can prevent the VMware Cloud Builder appliance from being able to resolve hostnames, leading to connection issues.

Incorrect Static IP configuration would result in the appliance being unreachable because it won't have the correct IP address or network configuration to communicate with other components.
