2V0-13.25 VMware Cloud Foundation 9.0 Architect Question and Answers

Asingle workload domain in VCFmaps to a single vCenter instance. When the host limit for that vCenter is reached (typically ~1000 hosts per vCenter), thecorrect and supported scale-out designis to deploy asecond VI workload domain, which comes with its own dedicated vCenter instance, allowing continued expansion without affecting the existing domain.

Requirementsdefine what the solutionmust deliver.

B (block-based storage in WLD)is atechnical requirementthat specifies a mandatory design need.

Other options:

A(must use existing storage) is aconstraint.

C(sufficient storage) is anassumption.

D(network team not trained) is arisk.

Hence, the validrequirementis thatblock-based storage must be used in the workload domain.

DuringVCF bring-up, SDDC Manager requirescontrol of a clean vCenter deployment. Since the existing environment already has a vCenter managing the clusters, thevCenter VM must be migrated to a standalone hostso that VCF bring-up can properly deploy its own vCenter instance.

A: NSX deployment happens later during WLD creation, not at fleet bring-up.

C: vSAN isn’t auto-configured — it requires explicit design.

D: VCF usesvLCM images, not baselines, post-deployment.

TheConceptual Modelidentifies high-level requirements, constraints, assumptions, and risks. TheLogical Designtranslates those intohow solution components (clusters, networks, storage, security zones, etc.) are structuredto meet dependencies and requirements.

Physical Designcomes after Logical Design and defines specific hardware, IP addresses, VLANs, etc.

High Availability Designis a subset of the logical/physical design focusing only on resiliency.

Configuration Guideis implementation-level documentation, not design.

Thus, theLogical Designdefines how the infrastructure’s capabilities are arranged to satisfy conceptual dependencies.

This is aconstraint, as it defines a non-negotiable time limit imposed by the customer’s budgeting timeline. It restricts the design phase’s schedule and deliverables. In VMware conceptual modeling, timing constraints are explicitly captured as constraints rather than requirements or assumptions.

Deployingtwo VCF Instancesallows isolation between environments. One instance can serve asdevelopment/testand the other asproduction.

This separation enables patch/upgrade validation without impacting production. VCF architecture supports managing multiple VCF instances in aFleetfor centralized visibility and policy enforcement.

VMware explicitly recommends separating environments for lifecycle testing in environments with strict change control policies.

The requirement specifying "yearly workload growth of up to 10%" relates directly to thesystem's ability to handle increased demand over time, which falls under the design quality ofPerformance. Performance in VMware Cloud Foundation design includes considerations for scalability and the ability to sustain projected growth. This requirement addresses the system’s capacity to manage future workload expansion without degradation in service levels.

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.

RTO (Recovery Time Objective)measures themaximum downtime toleratedbefore a service must be restored.

RPO (Recovery Point Objective)measures themaximum tolerable data loss.

In this scenario:

Business-critical workloads tolerate2 hours of data loss(RPO).

Infrastructure must be operational again within8 hours(RTO).

Thus, RTO =maximum allowable recovery time for service restoration.

VMware Cloud Foundation scales usingworkload domains (WLDs). Each WLD provides its own vCenter Server, NSX Manager, and lifecycle independence through SDDC Manager.

Byusing multiple WLDsfor each department, the architecture supportsindependent scaling, policy separation, and lifecycle management.

Option A or Crestricts flexibility as all tenants would share a single WLD, leading to lifecycle constraints and “noisy neighbor” issues.

Option Dcontradicts best practices: multiple departments should not share a single cluster inside a WLD when separation and lifecycle flexibility are required.

This design ensures seamless addition of new workload domains as departments and applications grow.

AProvider-managed Content Libraryis curated and controlled centrally by the VCF administrator or provider. It enables vetting and version control over VM templates and OVFs, ensuring compliance with organizational policies, including security reviews. This directly supports the requirement that all images must be reviewed and approved before being used in deployments.

To ensurezero RPO and high availability for the management domain, the best-fit design is to use avSAN Stretched Cluster. With a2ms latencyand shared witness site, this design enables synchronous replication and automatic failover, ensuringno data loss (RPO 0)andminimal downtime.

For the workload domains where24-hour RTO is acceptable,Live Recovery(leveraging replication and automation like Site Recovery Manager or Aria Automation Orchestrator) can be used to minimize operational effort and still meet recovery timelines. This strategy also aligns with minimizing hardware overhead by using the standby test infrastructure as failover capacity.

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.

TheNSX VPC Full Services Modelallows tenant isolation usingVRF-lite, enablingindependent routing tableswithin the same Tier-0 gateway.

This ensures dedicated external access without requiring a separate NSX Edge cluster per tenant, therebyminimizing the number of Edge clusters.

VMware VCF 9.0 recommendsVRF Litefor multi-tenant environments with centralized Edge clusters and segmented routing needs.

Constraints aredesign limitationsthat cannot be changed and must be worked around.

B(no funding for new storage, so existing must be used) is aclear constraint, as it restricts the architect from proposing new storage hardware.

A(out of maintenance) represents arisk(unsupported hardware may fail).

CandDarerequirements, not constraints, because they describe desired functionality of the solution.

Thus, the correct constraint is thatexisting storage must be used due to funding limitations.
