VMware VMware Cloud Foundation 5.2 Administrator 2V0-11.25 Exam Dumps: Updated Questions & Answers (October 2025)

The "Tunnel" status in NSX indicates the status of the VXLAN tunnels used for communication between ESXi hosts. If the MTU setting for the host Tunnel Endpoint (TEP) is incorrectly set to 1500, this can cause issues with VXLAN encapsulation, as VXLAN packets typically require an MTU of at least 1600 bytes to function correctly. Setting the MTU too low can cause packet drops and result in the tunnel status being down.

To apply software updates in a VMware Cloud Foundation deployment using the VMware Async Patch CLI Tool, the process involves downloading the patch bundle, uploading it to SDDC Manager, and then using the appropriate commands or tools to apply the patch. This ensures that the patch is properly staged in the environment and applied to the necessary components.

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.

As per theVMware Cloud Foundation Administration Guide, the official and supported process for moving all solution certificates under a Microsoft Certificate Authority, while keeping management and lifecycle operations compliant with SDDC Manager, is as follows:

C. Integrate the Microsoft CA into SDDC Manager.Exact Extract:

“To replace SSL certificates for VMware Cloud Foundation components using SDDC Manager, you must first integrate your Microsoft CA with SDDC Manager. This allows SDDC Manager to automate the certificate signing process using the organization’s enterprise CA.”

F. In SDDC Manager, replace the SSL certificates for vCenter, ESXi, NSX Manager, SDDC Manager and Aria Suite Lifecycle.Exact Extract:

“With Microsoft CA integration, you can use SDDC Manager to generate and replace SSL certificates for all key solution components, including vCenter, ESXi, NSX Manager, SDDC Manager, and Aria Suite Lifecycle. This process ensures full visibility and management through SDDC Manager.”

D. In SDDC Manager, replace the SSL certificates for vCenter, NSX Manager, SDDC Manager and Aria Suite Lifecycle.Exact Extract:

“Certificate replacement workflows in SDDC Manager allow you to select which managed components have their certificates replaced with CA-signed certificates. You must select and update all components that are not already using compliant CA-signed certificates.”

Why Not the Other Options?

A:ESXi certificate replacement should be managed via SDDC Manager for compliance, not directly in vCenter.

B:OpenSSL CA is not part of the company’s security policy or supported by the current workflow.

E:Aria Suite Lifecycle and its components already use CA-signed certificates, so this action is not needed.

Summary:

To ensure compliance with the updated security policy and maintain management with SDDC Manager, the administrator must:

Integrate the Microsoft CA into SDDC Manager (C),

Use SDDC Manager to replace all relevant solution SSL certificates for vCenter, ESXi, NSX Manager, SDDC Manager, and Aria Suite Lifecycle (F),

And use SDDC Manager’s certificate replacement workflow to update any components still requiring CA-signed certificates (D).These steps are mandated and supported by VMware Cloud Foundation official documentation.

Network IO Control (NIOC) must be enabled on the Virtual Distributed Switch (VDS) via the vSphere Client to begin configuring and managing bandwidth allocation and prioritization for different types of traffic.

After enabling NIOC, you can assign shares and limits to the specific port group (in this case, for storage traffic) to prioritize the traffic over other types of network traffic.

After an NSX Edge cluster is deployed into a workload domain, SDDC Manager provides built‑in operations to adjust the cluster size. According to theVMware Cloud Foundation 5.2documentation:

“After you create an NSX Edge cluster, you can use SDDC Manager toexpand or shrinkit by adding or deleting NSX Edge nodes.”

Breakdown of options:

B. Expand– You canaddone or more Edge nodes to increase the cluster size.

E. Shrink– You canremoveEdge nodes to decrease the cluster size.

These two actions are the only supported cluster scaling operations available in SDDC Manager post-deployment. Other operations—such as Redeploy, Sync, or Delete—are not available via the UI for a deployed Edge cluster and are either manual or unsupported in that context.

Summary:

Selected choicesBandEmatch the documented capability to scale an NSX Edge cluster via SDDC Manager.

No other operations (A, C, D) are supported for an existing Edge cluster through the UI.

First, configure the desired settings on a reference ESXi host. This host will be used as the template for creating a consistent configuration across the cluster.

After configuring the reference host, extract the host profile from it. This captures the configuration of the reference host as a host profile.

Remediation is necessary to ensure that other hosts in the cluster align with the reference host's configuration. The host profile can be applied, and remediation will correct any non-compliant settings on other hosts.

When expanding a VMware Cloud Foundation environment with a new workload domain, you have the flexibility to either configure a dedicated NSX Fabric for the new domain or join an existing NSX Fabric from either the management domain or a previously established VI workload domain. This allows for consistent and scalable network virtualization across multiple domains in the environment.

Ensure that a custom SSL certificate specifying the FQDN of the appliance is available: A custom SSL certificate for the FQDN of the Aria Suite Lifecycle appliance is required for secure communication between components.

Ensure that the NTP and DNS settings specified in SDDC Manager are valid for all management components: Accurate NTP and DNS settings are crucial for time synchronization and proper domain resolution in the environment.

Ensure the VMware Software Install Bundle for VMware Aria Suite Lifecycle is in the local bundle repository: The required software bundle must be available in the local repository to ensure successful deployment.

The first step in downloading the vSphere CLI tools is to visit the VMware Downloads page, where the vSphere CLI tools are available. From there, you can select the appropriate version for your environment and begin the download process.
