VCDX-VCF sample questions

Question 1

During a requirements gathering workshop for a VCF deployment, the client's CISO states: 'All management traffic must be strictly isolated from workload traffic, and we require the ability to patch the management stack independently of the workload infrastructure to maintain compliance.'

How should you translate this requirement into a VCF design constraint?

Accepted Answer

This requires a Standard Architecture model with a dedicated Management Domain and separate VI Workload Domains, enabling independent lifecycle management (LCM) for each domain.

Answer

This requires deploying SDDC Manager in an external vCenter Server outside the VCF boundary to isolate traffic.

Answer

This requires a Consolidated Architecture model where management and workloads share the same vSphere cluster but use different Resource Pools.

Answer

This requires the use of vSphere Lifecycle Manager (vLCM) images on a Consolidated Architecture to apply different ESXi versions to specific VMs.

Question 2

A healthcare provider requires a VCF architecture that supports 5,000 concurrent VDI users. The VDI workloads are highly ephemeral and memory-intensive. The design must minimize the blast radius of a cluster failure while maximizing resource utilization.

Which architectural approach for the VI Workload Domain best addresses these requirements?

Accepted Answer

Design a VI Workload Domain containing multiple smaller clusters (e.g., 8-12 hosts), managed by a single vCenter Server instance to balance failure impact with management overhead.

Answer

Design a single large VI Workload Domain with one 64-host cluster to maximize deduplication and compression efficiency.

Answer

Create a separate VI Workload Domain for every 500 users to ensure strict isolation.

Answer

Deploy the VDI workloads in the Management Domain resource pool to leverage existing infrastructure.

Question 3

You are designing a VCF environment where the customer demands that the management components (vCenter, NSX Manager, SDDC Manager) must be recoverable in a secondary region with a different IP schema.

Which VCF design construct is required to support the portability of these management components during a site failover?

Accepted Answer

Application Virtual Networks (AVNs) using BGP

Answer

Standard VLAN-backed Port Groups

Answer

vCenter Server High Availability (VCHA)

Answer

vSphere Distributed Switch (VDS) Port Mirroring

Question 4

A multinational enterprise requires a VCF design connecting three regional data centers.
- **Requirement 1**: Centralized security policy management across all sites.
- **Requirement 2**: Workload mobility (vMotion) between sites without IP changes.
- **Requirement 3**: Local egress for internet traffic at each site.

Based on the diagram below, which NSX architecture should be proposed?

subgraph "Management Plane Requirement"
Central[Single Pane of Glass Policy]
end
```

Accepted Answer

Three VCF instances configured with NSX Federation, using a Global Manager for centralized policy and Stretched Tier-0/Tier-1 Gateways.

Answer

A single VCF instance with a stretched management domain across all three sites.

Answer

Three independent VCF instances with NSX Multisite connected via L2 VPN.

Answer

Three VCF instances with HCX Network Extension for all workload mobility.

Question 5

You are designing the storage architecture for a VCF Management Domain. The customer wants to use vSAN ESA (Express Storage Architecture) to maximize performance on their NVMe-based hardware.

Which constraint must you verify before confirming this design decision?

Accepted Answer

The ReadyNodes must be certified specifically for vSAN ESA, not just general vSAN ReadyNodes.

Answer

The physical network switches must support Data Center Bridging (DCB).

Answer

vSAN ESA is only supported on VI Workload Domains, not the Management Domain.

Answer

Deduplication and Compression must be disabled for the Management Domain.

Question 6

Your client requires a VCF solution that supports mixed workloads including Virtual Machines and Kubernetes containers. They specifically need to provision Tanzu Kubernetes Grid (TKG) clusters directly via the vSphere Client.

Which TWO architectural components must be included in the design for the VI Workload Domain? (Select TWO)

Accepted Answer

vSphere with Tanzu enabled on the vSphere Cluster

Accepted Answer

NSX Edge Cluster deployed within or accessible to the Workload Domain

Answer

A dedicated vCenter Server for the Kubernetes control plane

Answer

Shared NFS storage only

Answer

VMware Aria Automation for cluster provisioning
