2V0-13.25 Practice Exam Questions with Answers VMware Cloud Foundation 9.0 Architect Certification

Physical Switch MTU set to 9000ensures optimal performance and reduced packet fragmentation for vSAN and NSX-T overlay networks—critical in HA scenarios.

vSAN Cache Tier Sizingat 800GB provides the necessary performance buffer to support high I/O operations and ensures continued service availability under failure or maintenance events.

Other options like DHCP lease time or NIC load-based routing do not directly influenceavailability SLAadherence.

In a multi-tenant environment,isolation, predictable performance, and scalabilityare critical.vSAN with tiered storage policiesenables the architect to defineperformance tiers(e.g., RAID-1 for critical workloads, RAID-5/6 for capacity-efficient workloads). This aligns with the need forlow latency and high IOPSfor tenant workloads, without oversubscribing or compromising performance.

Options A and D disregard tenant performance and isolation, potentially leading tonoisy neighborissues. Option B reduces availability and scalability and is contrary to best practices.

VCF Operations offers different deployment models based on scale and availability requirements:

Simple Model? Recommended forminimal footprintand greenfield deployments, where the organization wants to start small and expand later.

High Availability Model? Larger environments requiring immediate redundancy and scale.

Advanced / Standard Models? Targeted for more complex architectures with multi-site or advanced collection needs.

Since the customer’s goal isminimal footprint with future scalability, theSimple Modelis the correct choice.

The requirements specify:

Large-scale migration (800 workloads).

No downtime.

Strict change window (4 weeks).

HCX Replication Assisted vMotion (RAV)is the only method that combineslarge-scale migration efficiencywithzero downtime:

Workloads are replicated in advance.

During the cutover, avMotion-like switchovercompletes with no outage.

Other methods:

Cross vCenter vMotionworks for live moves but is not efficient forhundreds of VMswithin a short timeline.

HCX OS Assisted Migrationis for physical-to-virtual or non-vSphere workloads (not applicable).

HCX Bulk Migrationis efficient but introduces downtime during cutover.

Thus,HCX RAVbest meets the no-downtime, large-scale requirement.

Thefirst workshopfocuses onunderstanding business drivers, objectives, and outcomesbefore diving into design specifics. VMware design methodology stresses that architects shouldstart with business requirementsand then move toward conceptual, logical, and physical designs.

A and Care premature — topology and design decisions should not be presented before business outcomes are captured.

Bfocuses on product features, which is technical and should come later.

Dis correct because identifyingbusiness objectivesensures the architecture aligns with customer goals.

Business requirementsdescribe the high-level goals of the organization, typically related touser experience, cost reduction, compliance, or agility.

A(best end-user experience) aligns directly with business objectives.

B, C, and Daretechnical requirements: they specify infrastructure design behaviors (migration, security, SLA).

Therefore, thebusiness requirementis ensuring the bestend-user experience.

Since the constraint isexisting stretched cluster model, the design assumes a single cluster across two sites.

To meet theminimize downtime requirement, theSingle Management Zone Supervisor with HA control planeensures control plane resiliency within that stretched cluster.

Options with “Simple Availability” do not meet the high availability requirement. Options with three zones are not applicable because the constraint specifies a stretched cluster model.

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.

VCF Automation (Aria Automation) supportsmulti-tenancywith separate AD integration:

B: Each tenant must use theirown AD instance, aligning with independence across business units.

C: Create atenant per business unit, ensuring isolation and dedicated resource allocation.

D(projects per business unit) could work in a single-tenant scenario but doesn’t address multi-AD separation.

A/Eforce consolidation into corporate AD or single projects, violating independence requirements.

RTO (Recovery Time Objective) defineshow quickly a system/service must be restoredafter a disruption. In this scenario, the infrastructure components should be fully functional within 4 hours.

This contrasts with RPO, which measuresdata loss tolerance. RTO focuses ondowntime tolerance.

VMware Cloud Foundation documentation on BCDR (Business Continuity and Disaster Recovery) explicitly defines these metrics during availability planning.

In VMware Cloud Foundation 9.0,vSphere Lifecycle Manager (vLCM)withcomposite imagesis the recommended method for managing host lifecycle. However, when using hardware ofdifferent generations, it's not advisable to use asingle composite imageacross clusters with hardware inconsistencies due to potential compatibility mismatches with firmware and drivers.

By usingseparate vLCM composite imagesfor each cluster (i.e., management and workload), the architect ensures thateach cluster's image is optimized for its specific hardware generation, reducing the risk of driver/firmware issues during updates or drift remediation.

This design aligns with the principle ofcluster-level lifecycle independence, especially important when working with a mix of hardware generations.

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.

Dedicated NSX instances per workload domainprovide the highest level oflogical isolationand allowindependent upgrade cycles, fulfilling the requirement oftenant-specific customization. Each workload domain with its own NSX instance can be managed separately, updated independently, and configured with its own security policies, BGP/VRF, segments, and gateways.

NSX Federationcould achieve some level of centralization but does not support independent upgrade cycles per domain. Ashared NSX instancebreaks isolation and would tightly couple upgrade cycles, violating two of the key stated requirements.
