CompTIA PenTest+ PT0-002 Practice Question

The correct answer is to remove all reverse shells and backdoors that were installed during the testing process. This action ensures that no unauthorized entry points remain, which could be exploited by an attacker. Simply uninstalling tools doesn't guarantee that access methods created by those tools are also removed. Changing all passwords could be a prudent post-engagement action but it may not remove any shells that were installed. Checking for updates is important, but it focuses on patch management rather than the removal of intentionally installed access methods.
