In a VMware Cloud Foundation (VCF) environment, the correct sequence for deploying a new Workload Domain is as follows:

1. Install the ESXi hypervisor on the physical hosts to prepare them for integration into the VCF environment.

2. Commission hosts in SDDC Manager, which makes the hosts available for assignment to a workload domain.

3. Create a network pool for the Workload Domain, ensuring proper network segmentation and configuration for the domain.

4. Assign permissions on the newly deployed vCenter Server to provide necessary access and roles for administrators.

5. Deploy Workload Domain using SDDC Manager to set up the Workload Domain with the appropriate resources and configurations.

This order ensures that each step is completed in the necessary sequence for a successful Workload Domain deployment.

In VMware Cloud Foundation (VCF),vSphere Lifecycle Manager (vLCM)can manage clusters using eitherBaselinesorImages. However,NSX Manager instancesare tied to lifecycle management requirements across workload domains (WLDs) within VCF.

When deploying an additional VI Workload Domain (such as WLD03) and choosing to share an existingNSX Manager instance(from WLD02), there are specific requirements:

Consistency in Lifecycle Management: If a new workload domain (WLD03) is to share an NSX Manager with an existing domain (WLD02), it must use thesame vLCM modelas the domain it is sharing with. Since WLD02 is configured to usevLCM Images, WLD03 must also usevLCM Imagesfor consistency and compatibility.

Impact of NSX Manager Sharing: Sharing NSX Managers between workload domains can help reduce the footprint of management resources, as it avoids deploying additional NSX Manager instances. However, the domains sharing NSX must conform to the same lifecycle management approach to maintain a stable environment and streamline operations.

Rationale for Excluding Other Options:

Option B: Requiring WLD02 to switch to vLCM Baselines is incorrect because VCF does not support downgrading a domain from using Images to Baselines.

Option C: This would require modifying WLD01’s lifecycle configuration to use Images, which is unnecessary and unrelated to WLD03’s setup.

Option D: This option suggests that WLD01 must also share the same NSX Manager, which is not required. WLD01 can continue using its own NSX configuration independently of WLD02 and WLD03.

For Workload Management in VMware Cloud Foundation, VMware best practices recommend a minimum subnet mask of /24 for the ingress network. This provides sufficient IP addresses (256 addresses) to handle the requirements of Kubernetes services, load balancing, and potential future scaling within the workload domain. A smaller subnet, such as /27, would offer too few addresses and could restrict scalability, while larger subnets, like /22 or /18, are generally unnecessary and may be inefficient.

In VMware Cloud Foundation (VCF), licenses for vSphere and vSAN are managed through SDDC Manager. When adding a new cluster to an existing VI Workload Domain, the administrator should specify the required licenses in SDDC Manager, which centrally manages and applies the licenses to ensure compliance and compatibility across the environment.
