Question 600
During an architecture review, a platform engineer must recover a broken shared app installation by replacing the host with a tested image rather than modifying dozens of VMs ad hoc. Which option meets that requirement most directly?
Explanation
Correct Answer
Image-based rebuilds preserve shared app consistency. This addresses the stated need to recover a broken shared app installation by replacing the host with a tested image rather than modifying dozens of VMs ad hoc without substituting a different control.
Incorrect Answers
App virtualization separates packaged application contents from guest image. This is relevant when the task is to evaluate whether a supported virtualized application package can be delivered without installing its binaries into the base Windows image; it does not directly meet the requirement to recover a broken shared app installation by replacing the host with a tested image rather than modifying dozens of VMs ad hoc.
App compatibility needs real multiuser testing. This is relevant when the task is to stop a problematic app update from spreading to all multi-session users without a tested rollback option; it does not directly meet the requirement to recover a broken shared app installation by replacing the host with a tested image rather than modifying dozens of VMs ad hoc.
RemoteApp publishes installed Windows executable applications. This is relevant when the task is to expose an existing tested desktop application from a Windows session host without rebuilding the infrastructure; it does not directly meet the requirement to recover a broken shared app installation by replacing the host with a tested image rather than modifying dozens of VMs ad hoc.
