Which Is a Benefit of Application Virtualization?
Which of the following is a benefit of application virtualization?
Community Insight
The question tests a core virtualization concept benefit, and the trap is picking a cloud or networking trait—metered utilization belongs to cloud service models, not application virtualization.
Application virtualization runs apps in isolated virtual environments separate from the host OS, and its chief benefit is better compatibility, letting legacy or conflicting software run on modern systems. This page explains why 'Better compatibility' (A) is correct and why the other choices describe unrelated technologies.
The most tempting wrong choice is D, metered utilization, because it sounds like a modern IT benefit—but pay-per-use metering is a characteristic of cloud computing (such as IaaS/PaaS subscriptions), not of application virtualization.

Why the Answer Is Correct
Application virtualization packages an application so it runs inside an isolated container rather than being installed directly into the host operating system. Because the app depends on its own virtualized runtime and dependencies instead of the machine's exact configuration, it can execute on hosts where it would otherwise fail—giving better compatibility with newer or differently configured operating systems. This is precisely how administrators keep legacy or conflicting applications working alongside modern software. The community comment echoes this directly, noting that virtualized apps run "without being tightly tied to the local machine's setup."Why the Other Options Are Wrong
Reduced network latency (B) is a routing, bandwidth, or proximity concern and is not created by isolating an application's execution environment; virtualization can even add overhead. Secure telnet access (C) is nonsensical here because telnet transmits credentials and data in cleartext, and application virtualization does nothing to encrypt or secure a legacy remote-shell protocol. Metered utilization (D) describes the pay-as-you-go billing model of cloud service offerings, which is a cloud computing concept rather than a functional benefit of virtualizing an application.Community Comment Notes
Only one comment appears, and it supports option A: acf9805 selected "A — Better compatibility" and explained that application virtualization lets apps "run without being tightly tied to the local machine's setup." That reasoning matches the standard CompTIA framing of application virtualization as a compatibility and isolation tool.Exam Strategy
When a question asks for a 'benefit' of a specific technology, eliminate answers that belong to a different domain—latency is networking, telnet security is protocols, and metered utilization is cloud billing. The remaining choice that directly describes how that technology works is almost always correct.
Frequently Asked Questions
Why is metered utilization not a benefit of application virtualization?
Metered utilization refers to pay-as-you-go billing for consumed resources, which is a cloud computing characteristic (IaaS/PaaS/SaaS), not a functional outcome of virtualizing an application.
Does application virtualization reduce network latency?
No. Latency depends on routing, distance, and bandwidth; isolating an application on the host has no effect on how fast packets travel across the network.
