An administrator is deploying a VCF fleet with two VCF instances and wants a full-stack...

According to the VCF 9.0 Operations and Monitoring Guide:

Fleet Management: “VCF Operations Fleet Management enables cross-instance monitoring, unifying health and metrics across multiple VCF instances.”

Operations for Networks: “Provides application and network visibility, dependency mapping, and traffic analytics. Required to complete full-stack monitoring.”

Core VCF Operations is already deployed as part of the management stack and does not need to be added separately. Operations for Logs is optional for log aggregation, not mandatory for full-stack observability. The Management Pack Builder (C) is an add-on tool for custom packs, not a required component. Therefore, the correct two to add for full-stack monitoring are VCF Operations Fleet Management (A) and VCF Operations for Networks (E).
