B is correct. Deploying a dedicated NSX instance for each workload domain creates an independent networking and security management boundary for each domain. VCF supports workload domains either sharing an NSX Manager cluster or using their own NSX instance; Broadcom ' s VCF API documentation explicitly states that subsequent workload domains can share the existing NSX Manager cluster or create their own . ( Broadcom Developer )

A dedicated NSX instance best satisfies all three requirements. First, it provides stronger logical and administrative isolation , because NSX objects, policies, transport configuration, gateways, and tenant-specific networking remain associated with that workload domain ' s network stack. Second, separate NSX instances provide distinct lifecycle boundaries, reducing coupling when network components must be maintained or upgraded. Third, tenant-specific customization can be performed without introducing configuration dependencies or policy conflicts in another workload domain.

D reduces infrastructure footprint but creates a shared NSX management and lifecycle dependency between the workload domains. C is designed for consistent multi-site/global networking and policy synchronization, which works against the requirement for independent tenant network stacks. A removes the NSX capabilities needed for tenant-specific software-defined networking and security.

Broadcom ' s current VCF documentation confirms that isolated workload domains may be deployed with either dedicated or shared NSX, making the dedicated model the appropriate choice when stronger tenancy isolation is required . ( VMware )

C is required because BGP uses the AS_PATH attribute for loop prevention . If a Tier-0 gateway uses an autonomous-system number already present in an incoming route ' s AS path, the advertisement can be rejected as a routing loop. Assigning a unique private ASN to each Tier-0 gateway prevents this condition and is the documented VCF physical-network design consideration for the VPC Full Services model.

D addresses the explicit constraint that BFD cannot be used . Without BFD, failure detection falls back to BGP keepalive/hold timers. Broadcom ' s VCF configuration guidance uses 4-second Keep Alive and 12-second Hold Down timers when BFD is disabled, allowing three missed keepalives before declaring the peer unavailable. Therefore, the wording “3 retries and 12 hold down” is expressing this timer behavior.

E is not automatically justified by a 40+ Gbps requirement: UPT requires compatible DPU/SmartNIC-backed Edge interfaces and is not a generic VPC Full Services prerequisite. F does not solve AS-path loop detection. A conflicts with the centralized Full Services forwarding model, while B is unnecessary for a single-tenant design.

Functional requirements describe what the solution must accomplish or how it must behave , whereas non-functional requirements specify measurable qualities or operational characteristics such as performance, recoverability, security, and service levels. Broadcom ' s VCF architecture guidance explicitly distinguishes functional behavior from non-functional characteristics such as performance, scalability, and resilience. ( VMware Blogs )

A is functional because the platform must interact with the corporate password vault to store and retrieve service-account credentials. B specifies required identity functionality: authentication must integrate with an external SAML identity provider. C specifies required application behavior during a site failure—the applications must continue to tolerate loss of one data center. E is a clear user-facing function requiring users to view and track request progress.

By contrast, D specifies a security-assurance/testing target rather than platform functionality. F defines a measurable recoverability characteristic through a 10-minute RTO. G specifies a measurable SLO over a 12-month period and is therefore non-functional.

The VCF Architect exam guide specifically requires architects to distinguish business/technical requirements and relate solution requirements to AMPRS design qualities. ( Broadcom Docs )
