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

The correct mitigation for askills-based riskis tobridge the gapthroughtraining and upskilling. Providingtime and budgetfor training ensures that existing staff can competently support the solution and aligns with long-term sustainability of the environment.

Option A does not address the skills gap, just adds capacity. Option C is arisk identification tool, not amitigation step. Option D outsources the issue, which contradicts the goal of internal capability development.

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.

In aVCF Fleet with Disaster Recovery (AZ model):

vCenteris replicated to ensure management of vSphere workloads continues after a site failure.

NSXis replicated for networking continuity (segments, TEPs, Edge services).

Other components:

SDDC Manageris fleet-level and not replicated per AZ.

VCF AutomationandVCF Operationsareoptional add-onsand not replicated automatically by the DR model.

Thus,vCenter and NSXare replicated across AZs for resiliency.

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.

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.

TheVCF Identity Broker (VIDB)enables integration with enterprise identity systems and supports MFA. To reduce operational overhead:

Deploy VIDB oncein the first VCF instance atDC01.

Point all additional VCF instancesin the same private cloud to this VIDB.

This avoids deploying and managing multiple VIDB instances, reducing lifecycle overhead while still enabling 2FA.

Options A/B introduce unnecessary duplication. Option C centralizes in DC02, but requirement specifies DC01 is primary.

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.

The overall private cloud SLA is99.9%, butPlatinum applications require 99.99%, which exceeds the infrastructure SLA. VMware design methodology states:

If an application’s SLA ishigher than the infrastructure SLA, thenthe application itself must provide the additional resilience(e.g., clustering, active-active deployment, or application-level HA).

Options A and B reduce flexibility or impose unnecessary complexity.

Option D (Proactive HA) improves resiliency but cannot guarantee99.99%, since Proactive HA still depends on underlying infrastructure SLA.

Therefore, the only valid recommendation is thatPlatinum workloads must implement resilience at the application layer.

To support MFA and integration with third-party authentication,the external VCF Identity Broker model(VIDB) is required. Theexternal modelis designed to interface with advanced identity providers supporting MFA, which the embedded model cannot accommodate.

Furthermore, toavoid shared componentsacross multiple VCF instances and to reduce the impact of operational errors (e.g., configuration or certificate issues),a dedicated Identity Broker per VCF instanceensures complete separation and fault isolation.

This approach aligns with VMware’s recommended high availability and security practices for VCF 9.0. It ensures the MFA requirement is met and operational risks are minimized.

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.

Validating aBCDR strategy in VCF with vSAN DPrequires bothimpact analysisandactive testing:

B. Assess the impact of failover scenarios– Ensures application dependencies, such as inter-site routing, DNS, and external services, are validated against failover scenarios. This prevents unexpected downtime due to overlooked dependencies.

D. Planned and unplanned failover tests– VMware best practices emphasize testingboth scheduled and unexpected recovery workflowsto validate RTOs and confirm operational procedures.

Why not the others?

A(annual testing only) contradicts VMware guidance, which recommendsfrequent and scenario-based validation.

C(generic plans) reduces workload alignment; VMware requiresapplication-aware recovery plans.

E(vSphere HA/DRS) does not replace site-level recovery orchestration and validation — HA/DRS only handles local host failures, not site disasters.

To achieve99.95% availabilityin themanagement domain, the architecture must protectcritical management components (like vCenter)and ensure rapid recovery:

A. vCenter HA– Protects the vCenter Server by providing anactive-passive-failure detection architecture, ensuring no single vCenter outage impacts operations.

D. Restart priority policy = High– Ensures vCenter recoversfirst and fastestduring a host failure, minimizing downtime.

Why not the others?

B/E (EtherChannel Enable/Disable)– Link aggregation is networking config, not directly tied to SLA.

C (das.iostatsinterval = 0)– This disables HA datastore heartbeating,reducing resiliencyrather than improving it.

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.

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.

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.
