2V0-11.25 Exam Dumps - VMware Cloud Foundation 5.2 Administrator

Comprehensive and Detailed Explanation From Exact Extract:

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.

SDDC Manager automatically deploys and configures a new vCenter Server instance as part of the deployment of the VI workload domain.

SDDC Manager also handles the deployment of a new NSX Manager instance to provide network virtualization services for the VI workload domain.

To achieve an RPO of 0 (zero data loss) with continuous availability of storage across multiple sites, VMware Cloud Foundation leverages two key components:

vSphere (A):vSphere provides the core platform for compute virtualization, including features such as VMware vSphere HA (High Availability) and VMware vSphere Fault Tolerance, both of which are integral to delivering continuous VM availability and supporting cross-site failover.

vSAN (E):vSAN can be configured in a stretched cluster deployment across the three sites. With a stretched vSAN cluster, data is synchronously replicated between sites, ensuring that all writes are committed to more than one location. This synchronous replication provides true continuous availability and a Recovery Point Objective (RPO) of 0 in the event of a single site failure, provided that the network meets high bandwidth and low latency requirements.Other components such as Aria Operations and NSX do not provide storage-level availability or synchronous data protection. vSphere Replication only supports asynchronous replication and cannot guarantee RPO of 0.

According to theVMware Cloud Foundation 5.2 Administration Guideand troubleshooting documentation, when the SDDC Manager UI does not load even though the appliance is reachable and online, administrators should check both the health of services and the system resources. Here’s the detailed reasoning and exact documentation extracts:

Option C: Verify the health of the SDDC Manager services using the command sos --get-vcf-services-summary.Official documentation states:

“You can check the status of SDDC Manager services by running the sos command on the SDDC Manager VM. This command provides a summary of all SDDC Manager services and their current state. If any service is stopped or unhealthy, this may prevent the UI from loading.”

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.

When deploying an NSX Edge cluster in a VMware Cloud Foundation (VCF) environment, it must be deployed in the management domain. The management domain is responsible for managing and orchestrating various resources, including the NSX Edge cluster, which is crucial for network virtualization and security within the environment.
