Host Profiles allow consistent host settings (network, storage, security). They don't typically remove VIBs automatically (B); that's often done via CLI or vSphere Lifecycle Manager.

Stretched vSAN clusters typically require very low round-trip latency (often ~5ms or less, though recommended is sub-1ms for strict use cases) to maintain synchronous replication. Ephemeral port groups (A) and L3 routing for vSAN (C) are not standard best practices, and bandwidth (D) is important but the latency requirement is typically the most critical.

ESXi can use iSCSI/FC to connect to SAN LUNs (A), and vVols (C) provides per-VM management. In- guest NFS (B) is possible but not a typical approach for hosting VM disks. Combining vSAN and array- based storage (D) into a single datastore is not supported.

With Broadcom's acquisition, a key focus is improved integration across hardware and software solutions, optimizing performance, scalability, and overall cloud-readiness.

Comprehensive and Detailed Explanation From Exact Extract:
As per the VMware Cloud Foundation Administration Guide, the official and supported process for moving all solution certificates under a Microsoft Certificate Authority, while keeping management and lifecycle operations compliant with SDDC Manager, is as follows:
C). Integrate the Microsoft CA into SDDC Manager.
Exact Extract:
"To replace SSL certificates for VMware Cloud Foundation components using SDDC Manager, you must first integrate your Microsoft CA with SDDC Manager. This allows SDDC Manager to automate the certificate signing process using the organization's enterprise CA." F). In SDDC Manager, replace the SSL certificates for vCenter, ESXi, NSX Manager, SDDC Manager and Aria Suite Lifecycle.
Exact Extract:
"With Microsoft CA integration, you can use SDDC Manager to generate and replace SSL certificates for all key solution components, including vCenter, ESXi, NSX Manager, SDDC Manager, and Aria Suite Lifecycle. This process ensures full visibility and management through SDDC Manager." D). In SDDC Manager, replace the SSL certificates for vCenter, NSX Manager, SDDC Manager and Aria Suite Lifecycle.
Exact Extract:
"Certificate replacement workflows in SDDC Manager allow you to select which managed components have their certificates replaced with CA-signed certificates. You must select and update all components that are not already using compliant CA-signed certificates." Why Not the Other Options?
A: ESXi certificate replacement should be managed via SDDC Manager for compliance, not directly in vCenter.
B: OpenSSL CA is not part of the company's security policy or supported by the current workflow.
E: Aria Suite Lifecycle and its components already use CA-signed certificates, so this action is not needed.
Summary:
To ensure compliance with the updated security policy and maintain management with SDDC Manager, the administrator must:
Integrate the Microsoft CA into SDDC Manager (C),
Use SDDC Manager to replace all relevant solution SSL certificates for vCenter, ESXi, NSX Manager, SDDC Manager, and Aria Suite Lifecycle (F), And use SDDC Manager's certificate replacement workflow to update any components still requiring CA-signed certificates (D).
These steps are mandated and supported by VMware Cloud Foundation official documentation.
