2V0-13.25 Reviews Questions

VMware Cloud Foundation architecture uses the RACR framework (Requirements, Assumptions, Constraints, Risks) to classify inputs:

Business requirements describe high-level outcomes the business wants to achieve, often focusing on cost, efficiency, or customer satisfaction.

Technical requirements define how infrastructure should behave to meet performance, resiliency, or security needs.

Among the given options:

A (growth by 30%) and C (no SPOF) are technical requirements.

B (security and resiliency) is also a technical requirement.

D (reduce operational costs) directly aligns with business goals, making it the correct business requirement.

Comprehensive and Detailed Explanation from VMware Cloud Foundation 9.0 Documentation:

According to VMware Cloud Foundation 9.0 Design Guide (Table 59, “Certificate Management Design Recommendations”), VMware explicitly mandates that “Use a SHA-2 algorithm or higher for signed certificates. The SHA-1 algorithm is considered less secure and has been deprecated.” This recommendation (VCF-SEC-RCMD-CERT-002) is a foundational part of securing communication between management components and workload domains across the VCF environment.

The use of SHA-2 or higher ensures that all certificates used for SSL/TLS communication within the SDDC ecosystem (including vCenter, NSX Manager, and SDDC Manager) meet modern cryptographic standards to prevent vulnerabilities such as collision attacks. VMware Cloud Foundation enforces certificate management policies that require replacement of default VMCA-signed certificates with CA-signed certificates, and the SHA-2 algorithm ensures cryptographic integrity, authenticity, and resistance to tampering or impersonation.

This configuration directly satisfies the customer’s requirement for secure communication in the logical design of the workload domain. It ensures data in transit between components—such as management clusters, workload domains, and external systems—remains encrypted and trustworthy, aligning with VMware’s zero-trust and compliance-focused architectural principles.

The Conceptual Model identifies high-level requirements, constraints, assumptions, and risks. The Logical Design translates those into how solution components (clusters, networks, storage, security zones, etc.) are structured to meet dependencies and requirements.

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

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

Configuration Guide is implementation-level documentation, not design.

Thus, the Logical Design defines how the infrastructure’s capabilities are arranged to satisfy conceptual dependencies.

According to VMware Cloud Foundation 9.0 documentation, when a stretched cluster is deployed across sites with sub-5ms latency and high-speed interconnects, vSAN can be configured for zero RPO (Recovery Point Objective), ensuring 100% data consistency and availability in the event of a site failure. vSAN supports co-locating management and application workloads and provides the shared storage functionality with automatic failover capabilities.

Additionally, vSphere Virtual Volumes (vVols) provide granular control of virtual machine storage, and when backed by a storage system that supports replication and failover across sites (with support for VASA 3.0 or later), vVols can meet the same requirements for data availability and disaster recovery.
