5V0-31.22 VMware Cloud Foundation Specialist (v2) Questions and Answers

According to VMware Cloud Foundation Planning and Preparation Workbook, a statement that is true regarding NSX Manager configuration in a VMware Cloud Foundation environment is:

• The cluster virtual IP address (VIP) address must be used for API and GUI access to NSX Managers

vSphere Single Sign-On (SSO) provides secure authentication and authorization services for VMware Cloud Foundation components, including vCenter Server and Platform Services Controller (PSC). In a consolidated architecture deployment of VMware Cloud Foundation, the vSphere SSO configuration is shared across all the workload domains.

To ensure that subsequent workload domains can use the same identity sources as an external identity source registered in a consolidated architecture, the administrator needs to replicate the vSphere SSO configuration. This can be achieved by configuring the same identity sources for vSphere SSO across all the workload domains.

Configuring IWA (Integrated Windows Authentication) or LDAPS (Lightweight Directory Access Protocol over SSL) as an identity source is a part of configuring the vSphere SSO configuration for identity sources.

Keeping the pre-configured defaults does not guarantee that the subsequent workload domains will use the same identity sources as the external identity source registered in a consolidated architecture.

• To ensure that any subsequent workload domains can be accessed using the same identity sources, it is necessary to replicate the vSphere SSO configuration across all the workload domains in a consolidated architecture deployment. This can be achieved by replicating the vSphere SSO configuration between the primary and additional SDDC Manager instances. This ensures that all the workload domains registered with the SDDC Manager will be able to consume resources and services from the same identity sources without any additional configuration in each individual workload domain.

This is because according to Dell documentation1, to enable the Harbor Image Registry, you need to select the VM Storage Policy that will be used to store the images.

As part of enabling the Harbor Image Registry in VMware Cloud Foundation, a storage policy needs to be defined to specify the storage requirements for the registry. The storage policy should define the storage characteristics for the datastores where the registry will be deployed, including the redundancy level, disk type, and disk space. This is documented in the VMware documentation titled "Enabling Harbor Image Registry in Workload Domains."

This is because according to VMware documentation3, developers can only access Kubernetes storage classes that are mapped from VM Storage Policies. They cannot modify or delete them.

The service that is integrated with VMware Cloud Foundation and enables a centralized and simplified lifecycle management of ESXi host is Option B: vSphere Lifecycle Manager (vLCM) 1.

vLCM enables you to create cluster images for centralized and simplified lifecycle management of ESXi hosts including firmware. When a VI workload domain cluster is created with an image, you can update and upgrade the ESXi version on all hosts in the cluster collectively 1.

vSphere Lifecycle Manager (vLCM) is a key component of VMware Cloud Foundation (VCF) that enables centralized and simplified lifecycle management of ESXi hosts. It provides a single interface to manage host baselines, firmware and driver updates, and upgrades. With vLCM, administrators can create custom images for ESXi hosts, define baselines for host compliance, and apply updates to hosts in a coordinated manner. This helps to ensure consistency across the environment and reduce the risk of configuration drift. (source: VMware Cloud Foundation 4.x Architecture and Deployment Guide)

To expand storage capacity in a vSAN cluster with one disk group, you can either add more drives to hosts in the cluster, which is commonly referred to as scaling up, or add capacity drives to existing disk groups 

Option B: Add an additional disk group - According to search result [1], adding additional drives to a host will increase both capacity and performance[1], and each disk group contains one flash cache device and one or multiple capacity devices for persistent storage[2]. Therefore, adding an additional disk group to each host would increase the storage capacity of the vSAN cluster.

Option D: Increase the number of capacity disks in the existing disk group - Search result [1] explains that vSAN clusters require capacity and cache devices to function, and each disk group can contain multiple capacity devices for persistent storage[2]. Thus, an additional way to expand storage capacity in the vSAN cluster would be to increase the number of capacity disks in the existing disk group.

This is because according to VMware documentation, this is the tool that an administrator should use to perform this task of rolling out a new vSAN Witness appliance for a VMware Cloud Foundation stretched vSAN cluster. SDDC Manager provides a user interface and API for deploying and managing VCF components, including vSAN Witness appliances.
