Multiple Jetpack versions in Jetson Nano

The following command is showing me multiple versions of Jetpack:
sudo apt-cache show nvidia-jetpack | grep “Version”
Version: 4.6.3-b17
Version: 4.6.2-b5
Version: 4.6.1-b110
What is meant by multiple versions ? and which to follow ?

You can check which BSP is installed on your board first to know which jetpack should be in use.

Check /etc/nv_tegra_release.

I got the following output:
R32 (release), REVISION: 7.1, GCID: 29818004, BOARD: t210ref, EABI: aarch64, DATE: Sat Feb 19 17:05:08 UTC 2022
But how to check that which jetpack should I use ?

r32.7.1 is jetpack4.6.1
32.7.2 is jp4.6.2
32.7.3 is jp4.6.3
32.6.1 is jp4.6
32.5.x is jp 4.5.x.

This means that my jetpack is 4.6.1 ?
