2V0-13.25 Exam Dumps - VMware Cloud Foundation 9.0 Architect

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.

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.

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.

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.

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.

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.

BGP loop prevention relies onunique AS numbers. If the same AS is reused, routes may be dropped. In NSX VPC designs,assigning a unique private AS per Tier-0 gatewayensures clean routing without triggering loop detection.

A: Timer adjustment affects convergence, not loop detection.

C: iBGP with physical routers is non-standard and doesn’t solve the loop issue.

D: TEP traffic is unrelated to BGP routing loops.
