If stuck in bootloop:
The device this build targets—the Galaxy Tab E 9.6—was released around 2015. It was a mid-to-low-range tablet characterized by a 9.6-inch TFT display with a humble 1280x800 resolution and a Quad-core Spreadtrum processor.
By 2018, Samsung had long stopped updating this device. The official software was stuck on Android 5.1 Lollipop (or possibly Marshmallow in some regions). For owners of this tablet, a custom ROM was the only way to get a modern interface, better permissions management, and security patches.
If you were to flash this ZIP back in April 2018, you would be greeted with the clean, minimal interface of LineageOS 14.1 (Nougat).
