An employee at a graphic-design firm takes large numbers of photos on a company-issued smartphone. The pictures must automatically appear on the employee's office workstation, but the employee has just received an unexpectedly high LTE bill because the uploads are happening over cellular data. Which action should a technician take so the photos still back up automatically without using the cellular data plan?
Reduce the camera's image resolution to minimize file size.
Configure the photo-backup app to upload only when the phone is connected to Wi-Fi.
Disable background app refresh for the photo-backup application.
Enable unrestricted mobile-data access for the photo-backup application.
Most photo-backup services (Google Photos, iCloud Photos, OneDrive) include a setting that limits uploads to Wi-Fi. Enabling that Wi-Fi-only option (or turning the service's Cellular Data switch off) ensures the images are still synchronized whenever a trusted wireless LAN is available while preventing any uploads over LTE/5G. Disabling background refresh, lowering camera resolution, or granting unrestricted mobile-data access either stops synchronization altogether or continues to consume cellular data.
