A factory must try a risky browser plug-in where it cannot reach the office network. Which virtual-machine use fits?
Select an answer to reveal the explanation.
Short Explanation
You put the risky plug-in in a playpen, not on the factory floor. A sandbox virtual machine is that playpen, kept off the office network. Bridging it into the office, handing every employee a virtual desktop, or simply calling the plug-in old does not give you the isolation.
Full Explanation
A sandbox is an isolated virtual machine used so untrusted code can run without reaching production systems. The factory wants the plug-in off the office network, so a sandbox matches. A test virtual machine that is bridged onto the office network is on the network the stem wants to protect, so it does the opposite. Virtual desktop infrastructure delivers a desktop to users. It can be isolated, and it is a different project from penning in one plug-in. Legacy-app support lets an old program run on a newer system. Age of the program does not block network access. Exam caveat: the virtual switch has to be the isolated one. A sandbox whose adapter is left on the office VLAN is only a sandbox in name. Operational check: start the guest, confirm it cannot ping an office server, and only then open the plug-in. From the guest, ping an office file server and expect no reply before anyone opens the plug-in. Snapshot the clean sandbox so the next test does not inherit a contaminated guest. Keep the guest off the office VLAN.
