2V0-13.25 Questions and Answers

These are classicRecoverabilitymetrics. The Recovery Time Objective (RTO) and Recovery Point Objective (RPO) directly relate to how fast and how much data can be recovered after a failure or disaster event. The architect must ensure the VCF deployment includes recovery mechanisms, such as stretched clusters or backup/replication technology, that meet these defined RTO/RPO targets.

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.

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.

To trackconfiguration driftin VMware Cloud Foundation, the solution usesConfiguration Templatesand drift checks:

A: Template for the Management Cluster ensures cluster-level baseline is tracked.

B: Schedulingdrift checksevery 30 days ensures changes are detected.

D: Template forNSX Managerensures network and security components are included in drift detection.

C(Management vCenter) is not separately templated, it’s part of cluster drift.

E(remediation every 30 days) is not required — detection is enough.

F(Host Profiles) is vSphere-specific, not aligned with VCF’s drift management framework.

Upgrading avSphere + vSAN environmentto a fullVMware Cloud Foundation deploymentrequires introducing the components that make up theintegrated software-defined data center (SDDC):

A. NSX– Provides network virtualization, overlay segments, distributed firewalling, and routing required in VCF.

B. SDDC Manager– Thecore management and lifecycle automation toolof VCF, responsible for bring-up, patching, and upgrades.

E. vSphere Supervisor– Required to enableVMware Tanzu Kubernetes Grid (TKG)and modern application deployment in VCF environments.

Why not the others?

C. VCF Identity Broker– Provides federated authentication but isnot mandatory for initial upgrade. It is optional depending on identity requirements.

D. VCF Operations– This is VMware Aria Operations (for monitoring/analytics). While strongly recommended, it isnot requiredto upgrade from vSphere/vSAN to VCF.

TheManaged Telegraf Agentprovides full observability and is centrally managed through VMware Aria Operations (formerly vRealize Operations). It is ideal for scenarios where both OS and infrastructure application metrics are needed, such as in theFully ManagedandOS Managedservices. This meets the requirement for monitoring while minimizing manual overhead. The Self-Managed service does not require agent deployment, as only VM-level metrics are needed.

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.

Asingle VCF instance with dedicated Workload Domains per tenantstrikes the balance between operational efficiency and isolation. It reduces lifecycle tasks since only one management domain must be maintained, while each tenant having adedicated workload domainensures isolation of compute resources. This meets all three stated requirements effectively: lifecycle simplicity, minimal overhead, and tenant-specific compute separation.

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.

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.

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.
