220-1101 Question #349: Real Exam Question with Answer & Explanation

Question

A web developer needs to test the compatibility of web functions across multiple different browsers and versions of those browsers. The web developer only has one machine and cannot install multiple browser versions. Which of the following should the developer do to BEST resolve the issue?

Options

• APurchase more machines.
• BDeploy application virtualization.
• CTest using a virtual desktop.
• DSet up a multiboot configuration.

Explanation

Application virtualization is the best solution for testing multiple browser versions on a single machine without conflicts, as it packages applications to run in isolated environments.

Common mistakes.

• A. Purchasing more machines would resolve the issue but is a costly and inefficient solution compared to software-based virtualization methods.
• C. Testing using a virtual desktop (which implies Virtual Machine-based desktop environments) would require creating and maintaining multiple full operating system instances, which is more resource-intensive and less efficient than application virtualization for just running different browser versions.
• D. Setting up a multiboot configuration would involve installing multiple operating systems on the same machine, requiring reboots to switch between them and not allowing simultaneous testing, making it impractical for this scenario.
