Which technology enables the examination of various aspects of a VM without an agent?

Virtual Machine Introspection (VMI) is the correct answer because it allows for the examination and analysis of a virtual machine’s state, including its memory and execution processes, without the need to install software agents within the VM itself. VMI operates at a lower level than the virtual machine, typically through hypervisor or virtualization layer access, enabling security professionals to monitor and assess the virtual machine environment from the outside. This method is particularly beneficial for detecting malicious activity, as it can gather information without altering the state of the VM or relying on potentially compromised software.

The other options do not provide the same level of capability for examining a VM without an agent. System Monitoring Tools generally require installation within the VM to collect data, Remote Management Software typically facilitates management tasks rather than direct examination or analysis, and Cloud Management Platforms focus on broader cloud resources management rather than specific VM introspection. Thus, Virtual Machine Introspection is uniquely positioned to fulfill the requirement of non-intrusive examination of VMs.
