Which of the following is NOT scanned by VUM in virtual machines?

The correct answer is that network configurations are not scanned by VMware Update Manager (VUM) in virtual machines. VUM primarily focuses on maintaining and updating the compliance of virtual machine hosts, their underlying hypervisors, and VMware-related components.

When using VUM, the focus is on ensuring that the software components within the virtual environment are up to date, such as OS-level patches—critical for security and stability. VUM also manages the compatibility of virtual hardware, meaning it checks whether the virtual machines are running on hardware versions that adhere to current requirements and standards. Furthermore, it handles the configurations of virtual appliances to ensure they meet certain compliance and update criteria.

Network configurations, however, are generally not subject to such checks by VUM. Networking settings tend to be specific to the architecture and requirements of the applications running within the virtual machines, and changes in this area may often require direct administrative intervention or separate management tools rather than being part of the automated patching and compliance process overseen by VUM. Therefore, VUM's scope does not encompass the scanning of network configurations, since these are typically handled outside of its primary functions.
