An employee at a graphics-design firm needs the photos taken on a company-issued smartphone to be backed up automatically and appear on the office computer. The employee has complained about unexpected LTE overage charges that appear each time a photo shoot is done on location. Which action should the technician take to resolve the data-usage problem while still ensuring automatic backups?
Enable "Sync over Wi-Fi only" (or the equivalent Wi-Fi-only backup setting) in the photo-backup application.
Disable photo backup entirely until the project is complete.
Turn on the phone's mobile-hotspot feature while syncing the project photos.
Upgrade the smartphone's cellular data plan to a higher monthly allowance.
Selecting the "Sync (or Back up) over Wi-Fi only" option in the photo-backup settings allows the images to upload automatically whenever the handset is on a Wi-Fi network and prevents any uploads while it is on cellular data. This preserves the LTE data cap yet keeps the sync process fully automatic. Increasing the cellular plan would not control usage, disabling backup would eliminate the required functionality, and enabling cellular or hotspot features would raise data usage rather than reduce it.
