Asingle VCF instance with dedicated Workload Domains per tenantstrikes the balance between operational efficiency and isolation. It reduces lifecycle tasks since only one management domain must be maintained, while each tenant having adedicated workload domainensures isolation of compute resources. This meets all three stated requirements effectively: lifecycle simplicity, minimal overhead, and tenant-specific compute separation.

The constraint forces the use of the existing array. However, there’s ariskthat performance/capacity may be insufficient. VMware’s best practice for risk mitigation in RACR is toplan for contingency.

Ais correct because securingbudget allocation for additional hardwareaddresses the risk if the array cannot meet requirements.

B(RAID mirroring) improves redundancy, not performance or capacity.

Ccontradicts theconstraint(cannot ignore existing array).

D(extra Fibre Channel switches) doesn’t address storage array performance/capacity.

Thus, the best mitigation isbudget planning for new hardwareif the array fails to meet requirements.

In VMware Cloud Foundation, eachVI workload domainis backed bya single vCenter Server instance. By deploying multiple clusters within the same VI workload domain, the architect can supportmultiple use cases(e.g., separating prod/dev),without provisioning new vCenters. This design reducesmanagement overhead and operational complexity.

However, if stricter separation is needed (e.g., multi-tenancy or lifecycle independence), separate workload domains may be more suitable. While vSAN is the default, it's not mandatory unless vSAN Ready Nodes are used for bring-up.

BGP loop prevention relies onunique AS numbers. If the same AS is reused, routes may be dropped. In NSX VPC designs,assigning a unique private AS per Tier-0 gatewayensures clean routing without triggering loop detection.

A: Timer adjustment affects convergence, not loop detection.

C: iBGP with physical routers is non-standard and doesn’t solve the loop issue.

D: TEP traffic is unrelated to BGP routing loops.

D: Setting UserVars.SuppressShellWarning = 0 ensureswarnings are shown when shell access is used, improving auditability and compliance.

E: Usingcertificates signed by a trusted military Root CAaligns with security compliance standards for certificate trust and chain of custody.

Options A and C are operational best practices, but notmilitary hardening. B is about operations automation, not compliance-level hardening.

Due to theexplicit constraint that no internet accessis permitted, the VCF Installer cannot connect to an online depot. Instead, the architect must use theoffline depot model, where binaries are downloaded externally and made accessiblelocally within the VCF environment(e.g., using a local web server).

This setup aligns with VMware's"air-gapped" deployment guidancefor VCF environments with strict security postures.

This is arequirementbecause it specifieswhat the solution must deliver. VMware encryption requires enablingVM Encryption with vSphere VM Encryption policies or vSAN encryption.

Constraintsare design limitations (e.g., budget, existing hardware).

Risksare potential negative outcomes (e.g., encryption introduces CPU overhead).

Assumptionsare unverified statements taken as true (e.g., "all VMs can support encryption").

Thus, “All VMs must be encrypted” is asecurity requirement.
