For a new VCF fleet in which VCF Operations ultimately needs to operate in Continuous Availability (CA) mode, the initial deployment is performed using the supported VCF Installer workflow with VCF Operations in High Availability (HA) mode. Therefore, F is required as the starting deployment configuration.

After the VCF Operations HA deployment is operational, the cluster is converted from High Availability mode to Continuous Availability mode, making C the second required action. Continuous Availability uses a dual-site architecture and requires a witness node to participate in determining cluster availability and prevent split-brain conditions. Consequently, the administrator must also deploy the required VCF Operations Witness node, making D the third required step.

Option A applies when an existing VCF Operations deployment is available to connect to, which contradicts the scenario of deploying a new VCF fleet. Option B incorrectly suggests deploying a separate CA cluster rather than converting the deployed HA cluster. Option E would omit VCF Operations during initial fleet deployment and does not follow the required deployment sequence.

When using Fibre Channel (FC) as the principal storage type for a workload domain in VMware Cloud Foundation, storage must already be provisioned and visible to all participating ESXi hosts.

The VCF documentation specifies that for VMFS on FC deployments:

Storage LUNs must be created on the SAN.

The LUNs must be zoned and presented to all ESXi hosts.

Hosts must be able to detect the presented LUNs before domain creation.

Incorrect options:

SSD disks (A) are required for vSAN, not Fibre Channel.

Port binding (B) is required for iSCSI, not FC.

A VMkernel interface for storage (D) is required for IP-based storage (NFS/iSCSI), not Fibre Channel.

Therefore, the key prerequisite is ensuring LUNs are presented to all ESXi hosts.

The requirement is to ensure DNS records are created only when a domain name is provided.

Since the blueprint includes a custom property for domainName, the correct conditional logic in the event subscription must validate that this property is not null.

Adding the condition:

event.data.customProperties[ ' domainName ' ] != null

ensures the workflow executes only when the domain name is provided.

Option B validates hostname instead of domain name.

Option A controls workflow blocking, not conditional execution.

Option C relates to cleanup, not creation condition validation.
