This is because according to VMware documentation1, the VMware Imaging Appliance (VIA) is a tool that automates ESXi host imaging and configuration for VCF deployments. It supports custom ESXi images that include additional drivers or VIBs that are not part of the base ESXi image2. You can download ESXi software and VIBs from VMware or third-party sources and upload them to VIA for creating custom images3.

12-29 vSphere Lifecycle Manager Baselines and Images

You use vSphere Lifecycle Manager baselines and baseline groups to perform the following tasks:

• Upgrade and patch ESXi hosts. •

Install and update third-party software on ESXi hosts.

You use vSphere Lifecycle Manager images to perform the following tasks: •

Install the desired ESXi version. • Install and update third-party software on ESXi hosts in a cluster.

• Update and upgrade the ESXi version in a cluster. • Update ESXi host firmware in a cluster. • Generate and use a recommended image for your cluster. • Check the hardware compatibility of hosts and clusters.

A supported function of the vSphere Lifecycle Manager (LCM) in VMware Cloud Foundation (VCF) is to check hardware compatibility of hosts and clusters. This function allows you to verify that the hosts and clusters in your VCF environment meet the requirements for the desired state image that you want to apply. You can also view the compatibility status and details of each host and cluster in the SDDC Manager dashboard1.

erasure coding vSAN storage policy with the ability to tolerate two host failures requires at least six fault domains (hosts) in a cluster. Therefore, an 8-hosts cluster can meet this requirement for DEV/UAT workloads. Additionally, creating separate workload domains for DEV/UAT and DMZ can provide full management and network isolation between these two zones.

This is because according to VMware documentation, this is one of the supported design options for deploying NSX-T Bare Metal Edge nodes for VMware Cloud Foundation VI workload domains. Sharing an NSX-T Manager cluster between both workload domains can reduce costs by minimizing the number of NSX-T licenses required. Adding the NSX-T Bare Metal Edge cluster to the shared NSX-T Manager cluster can satisfy a requirement for extremely low latency by providing direct access to physical network interfaces.

This is because a network pool is a collection of subnets within an layer-2 network domain that includes information about subnets reserved for the vMotion and NFS networks that are required for adding a host to the SDDC Manager inventory2. The other options are not correct because they either include vSAN network, which is not needed for external NFS or VMFS on FC storage2, or they do not include NFS network, which is needed for external NFS storage1.

You create VI workload domains to run customer workloads. For each VI workload domain, you can choose the storage option - vSAN, NFS, vVols, or VMFS on FC.

VMware Cloud Foundation supports several storage types as principal and supplemental storage for VI workload domains. Principal storage is the initial shared storage type that is selected during the creation of a workload domain or cluster in SDDC Manager. Supplemental storage is the additional shared storage type that can be added after a cluster has been created using the vSphere Client.

The supported principal storage types for VI workload domains are:

vSAN

NFS v3

vVols (FC, iSCSI, or NFS)

The supported supplemental storage types for VI workload domains are:

vSAN

NFS v3 or v4.1

vVols (FC, iSCSI, or NFS)

VMFS on FC

iSCSI

NVMeoF/TCP

Therefore, the only option that contains only supported storage types for VI workload domains is B. NFS v3, NFS v4.1, vSAN.

After creating storage policies, a vSphere administrator can perform the following tasks: Assign the storage policies to the Supervisor. The storage policies configured on the Supervisor ensure that the control plane VMs, pod ephemeral disks, and container images are placed on the datastores that the policies represent. Assign the storage policies to the vSphere Namespace. Storage policies visible to the namespace determine which datastores the namespace can access and use for persistent volumes. The storage policies appear as matching Kubernetes storage classes in the namespace. They are also propagated to the Tanzu Kubernetes cluster on this namespace. DevOps engineers can use the storage classes in their persistent volume claim specifications.

According to the VMware Cloud Foundation documentation1, an external SFTP server is recommended for storing backups of SDDC Manager and NSX-T Manager for the following reasons:

It provides better protection against failures because it decouples NSX-T backups from SDDC Manager.

It is a prerequisite for restoring SDDC Manager file-based backups.

Therefore, statements B and D are correct and should be shared with the customer.

By default, NSX Manager file-based backups are taken and stored on an SFTP server that is built into the SDDC Manager appliance. It is recommended that you configure an external SFTP server as a backup location for the following reasons: An external SFTP server is a prerequisite for restoring SDDC Manager file-based backups. Using an external SFTP server provides better protection against failures because it decouples NSX backups from SDDC Manager.

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.

To provide identity and access management services to the cross-instance SDDC components, you create a global environment in vRealize Suite Lifecycle Manager in which you deploy a 3-node clustered Workspace ONE Access instance.

Workspace ONE Access is a service that provides identity and access management for the VMware Cloud Foundation environment. It enables single sign-on, multi-factor authentication, conditional access policies, and user lifecycle management for the SDDC components and workloads12

vRealize Suite Lifecycle Manager is a service that provides lifecycle management for the vRealize Suite products, such as vRealize Automation, vRealize Operations Manager, vRealize Log Insight, and Workspace ONE Access. It automates the deployment, configuration, patching, upgrading, and scaling of these products34

When you deploy a 3-node clustered Workspace ONE Access instance using vRealize Suite Lifecycle Manager, you are creating a highly available identity and access management service for your VMware Cloud Foundation environment.
