VMware 5V0-31.22 - VMware Cloud Foundation Specialist (v2)

This is because according to VMware documentation1, vSphere Native Key Provider (NKP) is a simple key management solution that does not support key replication across sites or clusters. It also does not support vSphere Virtual Machine encryption which requires a third-party KMS solution2. Therefore, to enable both vSAN data at rest encryption and vSphere Virtual Machine encryption in a multi-site VCF solution, you need to use a third-party KMS solution that allows for key replication across sites.

The SDDC Manager UI provides a single point of control for managing and monitoring your VMware Cloud Foundation instance and for provisioning workload domains. You use the navigation bar to move between the main areas of the user interface 1. The SDDC Manager UI provides an integrated view of the physical and virtual infrastructure and centralized access to manage the physical and logical resources 2.

The REST API can also be used to create a new VI workload domain using VMware Cloud Foundation. The VMware Cloud Foundation API Reference Guide provides information on available operations 3.

This is because according to VMware documentation, these are some of the storage options that can be used for a new VI Workload Domain:

vSAN principal storage with VMFS on FC supplemental storage: You can use vSAN as your primary storage platform and add VMFS on FC as an additional storage option.

vSAN principal storage with NFS supplemental storage: You can use vSAN as your primary storage platform and add NFS as an additional storage option.

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 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.

The three NSX components that are automated during the deployment of an edge cluster in a VMware Cloud Foundation environment are:

Edge VM deployment: SDDC Manager deploys the NSX Edge node virtual appliances on the vSphere cluster that backs the workload domain1.

Edge Uplink Profile configuration: SDDC Manager configures the edge uplink profile with the MTU, teaming policy, and transport VLAN settings for the edge nodes1.

Tier-0 and Tier-1 gateway configuration: SDDC Manager creates a tier-0 gateway and a tier-1 gateway for the edge cluster, and configures the routing, NAT, and firewall rules for them1.

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.
