What is the storage capability for the site support subsystem (SSS) digital audio tapes (DAT)?

Explanation:
The question tests how to read storage specifications for the site support subsystem’s DAT tapes by distinguishing native capacity from compressed capacity. For these SSS DAT tapes, the native capacity is 36 GB per tape. If the data can be effectively compressed, you can store about 72 GB on the same tape, which is roughly a 2:1 compression factor. Understanding native versus compressed capacity helps you plan backups: native means the raw amount of data the tape can hold without any compression, while compressed assumes data becomes smaller when encoded, so the usable capacity increases accordingly. Not all data compresses well, so the actual usable capacity can vary, but the spec used here reflects an expected 2x compression for typical backup data. The other numbers don’t fit the established SSS DAT specification: 12 GB is far below the nominal native capacity, 100 GB exceeds the typical maximum for these tapes, and 8 or 16 GB represents too small a native capacity.
