VMware 2V0-13.25 Dumps Questions Answers

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.

VCF networking guidance emphasizes independent uplinks and notes that while LACP is supported, it is not recommended and introduces additional operational considerations. Specifically: “Link aggregation to the host is supported but not recommended—the default switch-independent load-based teaming (LBT) provides benefits similar to those of LACP without added configuration complexity.” It further states: “Use of LACP… requires specific LACP configuration and switch setup… Not all vSphere features are supported with LACP… [and is] API only.” The design recommendation is: “Ensure each connection between the fabric switch and host operates as an independent uplink.”

Given the customer constraint that the VMware Administration team cannot re-configure the physical network, the prerequisite physical switch port-channel configuration for LACP cannot be performed. During bring-up and life-cycle operations, the Management Domain must follow VCF’s standardized, automated patterns and therefore cannot rely on fabric changes the team cannot make. As a result, LAG cannot be used in the Management Domain, and the design must adopt independent uplinks (LBT) for management, vMotion, and VM traffic while using NFS as principal storage per the NFS Storage Model.

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

Furthermore, to avoid shared components across multiple VCF instances and to reduce the impact of operational errors (e.g., configuration or certificate issues), a dedicated Identity Broker per VCF instance ensures 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.
