CompTIA A+ 220-1102 Practice Question

The option to check available storage on the device is the most effective step because insufficient storage is a common reason for failed updates. If the device does not have enough space to accommodate the update files, the installation will fail.

Other choices might address the issue, but are not as directly related to the immediate need to resolve the update failure. For example, restarting the device can help, but if there is insufficient storage, the update will still fail. Similarly, verifying network connectivity is relevant, but storage issues are often the more common cause.
