The correct answer is A. Better compatibility .

According to CompTIA A+ Core 1 220-1201 objectives under Software Troubleshooting and Virtualization:

Application virtualization allows applications to run in an isolated environment on a client device without being installed directly on the operating system.

This improves compatibility , as applications can operate regardless of OS differences, avoiding conflicts with other installed applications or system configurations.

Why the other options are incorrect:

B. Reduced network latency: Application virtualization does not inherently reduce network latency; network performance depends on connectivity.

C. Secure telnet access: Telnet is unrelated to application virtualization.

D. Metered utilization: Metering refers to cloud service usage or billing, not a benefit of application virtualization itself.
