An administrator is tasked to upgrade an existing VMware Cloud Foundation (VCF) 5.

Upgrading from VCF 5.2 to VCF 9.0 involves a significant architectural transition. The VCF 9.0 Upgrade Guide outlines the sequence for environments previously using Aria components.

Deploy VCF Installer (E):VCF 9.0 introduces the VCF Installer appliance to orchestrate deployment and lifecycle operations. This must be deployed first.

Deploy NSX Manager 9.0 (A):NSX must align with the new VCF 9.0 architecture before further component integration.

Manually upgrade Aria Operations to VCF Operations 9.0 (D):Aria Operations transitions to the integrated VCF Operations platform. This is not automatic in major version transitions and requires administrator-driven upgrade.

Options B and F are incorrect because automatic upgrade paths are not supported for this major version shift. Option C is not part of the initial mandatory sequence before platform alignment.

Therefore, the correct three are:

Deploy NSX Manager 9.0, Manually upgrade Aria Operations to VCF Operations 9.0, and Deploy VCF Installer appliance.
