At the Permissions setting, add the DevOps group and assign the “Editor” permission. This is the recommended way to grant the DevOps team permissions to a vSphere Namespace in a VMware Cloud Foundation (VCF) developer-ready workload domain while following the principle of least privilege access. According to the VMware Cloud Foundation documentation1, the Editor permission allows users to create, modify, and delete objects within a vSphere Namespace, such as vSphere Pods, Tanzu Kubernetes clusters, and stand-alone VMs. The Editor permission also allows users to view and manage storage policies, VM classes, and content libraries for the namespace1

B. At the Global Permissions setting, add the DevOps group and assign the vSphere Kubernetes Manager role is not a correct option, because it will grant more privileges than necessary to the DevOps team. The vSphere Kubernetes Manager role is a global role that allows users to manage all aspects of vSphere with Tanzu, such as enabling Workload Management on clusters, creating and configuring vSphere Namespaces, and managing storage policies and VM classes. This role should be assigned only to vSphere administrators who are responsible for configuring and maintaining the VCF developer-ready workload domain1

C. At the Global Permissions setting, add the DevOps group and assign the SupervisorService Cluster Operator role is not a correct option, because it will also grant more privileges than necessary to the DevOps team. The SupervisorService Cluster Operator role is a global role that allows users to manage all aspects of Supervisor Services on clusters, such as creating and configuring Supervisor Service namespaces, managing service accounts and roles, and deploying service instances. This role should be assigned only to vSphere administrators who are responsible for enabling and managing Supervisor Services on VCF developer-ready workload domains1

D. At the Permissions setting, add the DevOps group and assign the “Can edit” permission is not a correct option, because there is no such permission in vSphere with Tanzu. The available permissions for vSphere Namespaces are Viewer, Editor, and Admin. The Viewer permission allows users to view objects within a vSphere Namespace, but not create or modify them. The Admin permission allows users to perform all actions within a vSphere Namespace, as well as manage permissions for other users or groups1

These are valid use cases for multiple clusters in a workload domain according to VMware documentation. A workload domain with multiple availability zones each containing clusters can provide high availability and disaster recovery by distributing workloads across different physical locations within a region. A workload domain with multiple clusters in one rack can provide scalability and flexibility by allowing different configurations and policies for different clusters within a single logical unit. Two clusters forming one stretched workload domain can provide resiliency and fault tolerance by synchronizing data across two sites within a region.

A NSX Tier-1 Gateway provides the functionality of a downlink connection to segments in a vSphere with Tanzu deployment. According to the VMware documentation1, a segment is a virtual layer-2 domain that can be either overlay-backed or VLAN-backed. A NSX Tier-1 Gateway connects to one or more segments and provides routing and security services for the workloads attached to those segments. A NSX Tier-1 Gateway also connects to a NSX Tier-0 Gateway, which provides uplink connectivity to external networks2

The minimum number of hosts required for a new vSAN cluster is three, according to the VMware Cloud Foundation documentation1. This is because a vSAN cluster needs at least three hosts that contribute capacity to the cluster to form a quorum and tolerate failures. However, for best results and availability, VMware recommends adding at least four hosts to the cluster2

According to the VMware documentation, each NSX-T Local Manager is associated with a vCenter Server, and each NSX-T Local Manager can manage up to three vCenters. In a VCF deployment with two environments (PROD and DEV) and two different hardware server types in PROD, there would be a total of three vCenter Servers. Therefore, a total of three NSX-T Local Managers would be provisioned to manage the three vCenter Servers.

This is because according to VMware documentation2, these are some of the prerequisites for enabling workload management for a VMware Cloud Foundation Management Workload Domain:

You must have a vSphere cluster with NSX-T networking configured.

You must have vSAN File Services enabled on your cluster.

You must have vSphere HA and DRS enabled in fully automated mode on your cluster.

The other options are incorrect because they are not required or supported for this deployment.

According to the VMware KB article Understand vMotion networking requirements (59232), a successful Long Distance vMotion requires a RTT (round-trip time) latency of 150 milliseconds or less, between hosts. This is the maximum accepted latency supported by vMotion across long distances1

An architect is decommissioning a host from a VI Workload Domain and wants to reuse it in a VMware Cloud Foundation environment.

Which statement accurately describes this process?

A. Use the decommission host workflow against a host with an unassigned state, and then run the commission host workflow.

B. Use the decommission host workflow against a host with an unassigned state, re-image the host, and then run the commission host workflow.

C. Use the decommission host workflow against a host with an assigned state, re-image the host, and then run the commission host workflow.

D. Use the decommission host workflow against a host with an assigned state, and then run the commission host workflow.

Answer: B

If you want to re-use a host in a different workload domain, you must decommission, re-image, and commission the host before adding it to the workload domain. The hosts that you want to decommission must not be assigned to a workload domain. If a host is assigned to a workload domain, you must remove it before you can decommission it. See Remove a Host from a vSphere Cluster in a Workload Domain.

According to Networking Requirements for vSAN1, the maximum network latency between the two main sites for stretched clusters is 5 ms RTT (round-trip time). This means that the latency between any two nodes in different availability zones should not exceed 5 ms.

"When more capacity is needed, scaling the consolidated design is an option but a much better design option for a larger scale is to use workload domains. After you reach 8 or 10 nodes in the consolidated design, consider migrating to a standard design. If you migrate to a standard design, the default small vCenter Server Appliance size should be enough for most designs."

 According to the VMware Cloud Foundation documentation1, a consolidated architecture is suitable for smaller deployments that have 6 or fewer nodes, while a standard architecture is recommended for larger deployments that have more than 6 nodes. A consolidated architecture has some limitations and trade-offs compared to a standard architecture, such as less scalability, flexibility, and isolation. Therefore, if the customer’s workload demand increases and requires more capacity, migrating to a standard architecture should be considered.
