220-1101 Question #217: Real Exam Question with Answer & Explanation

Question

Which of the following would be the BEST reason to use a virtual machine as a sandbox?

Options

• ATo test new software in a safe environment
• BTo increase the efficient use of computing resources
• CTo run multiple machines on the same hardware
• DTo have dedicated hardware for a single system

Explanation

A virtual machine provides an isolated testing environment, making it the best choice as a sandbox to safely evaluate new software without impacting the host system.

Common mistakes.

• B. While VMs can contribute to efficient resource use by consolidating workloads, this is a general benefit of virtualization, not the primary reason for using a VM specifically as a sandbox.
• C. Running multiple machines on the same hardware is a core feature of virtualization, but it describes the underlying technology rather than the specific purpose of using a VM as a sandbox for testing.
• D. A VM by definition shares hardware resources, so using it to have dedicated hardware for a single system is incorrect and contradicts the nature of virtualization.
