Uninstalling and reinstalling the application can resolve the issue of it crashing immediately on an Android tablet, as it can fix any corrupted or missing files or settings. Clearing the application storage can also resolve the issue, as it can free up space and remove any conflicting data. Gaining root access to the tablet, resetting the web browser cache, deleting the application cache and disabling mobile device management are not likely to resolve the issue, as they do not affect how the application runs.

Power Plans are Windows settings that allow a user to configure how a laptop’s screen behaves when plugged in or running on battery power. They can adjust the screen brightness and the time before the screen turns off due to inactivity.

The correct answer is A. Verify the DNS server settings. This is because the DNS server is responsible for resolving domain names to IP addresses, which is necessary for accessing the internet or named network resources. If the DNS server settings are incorrect or the DNS server is down, the technician will not be able to access these resources even if they have a valid IP address and can ping the default gateway1.

Preserving chain of custody is a concept that refers to the documentation and tracking of who handled, accessed, modified, or transferred a piece of evidence, when, where, why, and how. Preserving chain of custody can help establish the authenticity, integrity, and reliability of the evidence, as well as prevent tampering, alteration, or loss of the evidence. An administrator who documented the movement of the evidence demonstrated the concept of preserving chain of custody. Implementing data protection policies, informing law enforcement, and creating a summary of the incident are not concepts that describe the action of documenting the movement of the evidence.
