An administrator is preparing to deploy VMware vSphere Foundation using the VMware Cloud Foundation (VCF) Installer wizard. During host onboarding…

The standard VMware Cloud Foundation (VCF) Installer wizard, also known as the Cloud Builder UI, is designed for simplicity and expects uniform root credentials for all ESXi hosts being added to the management domain. When hosts have differing passwords, the UI-based validation will fail. To proceed, the administrator must use the API-driven deployment method. This method utilizes a JSON specification file where individual configuration details, including unique root credentials (rootPassword), can be defined for each ESXi host object. This allows the VCF bring-up process to successfully authenticate to each host despite the non-uniform passwords.

A. The standard VCF Installer wizard does not have a feature to override credentials for specific hosts during the staging or validation phase.

B. The deployment wizard is streamlined for bulk operations and does not provide a user interface to enter credentials manually for each host.

C. Setting a password expiration policy is a security configuration on the ESXi hosts and does not resolve the immediate authentication issue during VCF deployment.

1. VMware Cloud Foundation Deployment Guide (Version 5.1): This guide details the two methods for deployment: using the Cloud Builder UI and using the VCF API. The API method is specified for complex or automated deployments. The guide states

"You can deploy the VCF instance by using the VCF API. You provide the deployment specification as a JSON file." The structure of this JSON file allows for per-host definitions.

2. VMware Cloud Foundation API Reference: The official API documentation explicitly shows the JSON structure required for adding hosts. For the API endpoint that validates and adds hosts

the request body includes an array of host specifications. Each element in the array is a host object that contains its own specific credentials block

including username and password. This confirms that the API is designed to handle per-host credentials.

API for POST /v1/hosts/validations and POST /v1/clusters/{id}/hosts. The HostSpec or EsxiSpec object model within the request body contains a credentials object for each host.
