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 VMware documentation1, SDDC Manager is responsible for checking and downloading the online bundles for VCF upgrades from depot.vmware.com. The administrator can access SDDC Manager and download the bundles from Inventory > Workload Domains > MGMT > Update/Patches.

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.

The two configuration steps that a VMware Cloud Foundation administrator must apply to achieve north/south connectivity while setting up an edge VM node for a workload domain from the SDDC Manager user interface are:

NSX VDS Uplinks

BGP Configuration

According to the web search results, the NSX VDS uplinks are required to connect the edge VM node to the physical network and provide north/south traffic for the overlay and public networks. The NSX VDS uplinks must be configured with named teaming policies that pin the traffic to specific VLANs and uplink ports1. The BGP configuration is required to enable dynamic routing between the NSX Tier-0 gateway and the physical routers. The BGP configuration must be done on both the NSX-T Data Center and the ToR switches2.

when upgrading ESXi software on Dell EMC PowerEdge servers using SDDC Manager Lifecycle Management (LCM), you must use a Dell EMC customized image that contains drivers for specific hardware components such as storage adapters.

This is because according to VMware documentation45, VCF supports two architecture models - standard and consolidated. The standard architecture model separates management workloads and user workloads into different domains, while the consolidated architecture model combines them into one domain. For a hybrid model that coexists with VMware on AWS cloud DR solution, the standard architecture model is recommended as it provides workload isolation and mobility across VCF instances6. The minimum requirement for creating a management domain or a VI workload domain is three hosts45.

According to the VMware Cloud Foundation documentation on network requirements, vSAN requires only the vMotion and NFS networks to be configured in the network pool. This is because vSAN traffic can be carried over the vMotion network, and the NFS network is needed to support the use of NFS datastores [1].

NFS is a file-based storage protocol that can be accessed over IP networks. It does not require any special hardware or software, and can be accessed by any device that supports the NFS protocol [2]. As such, it only requires the NFS network to be configured in the network pool.

Therefore, the correct answers are B. NFS and E. vSAN.
