Point-in-time restore sounds useful, but does it really prevent data loss?

High concurrency optimization doesn’t really fit this scenario.

I'm a bit confused on this one. I know the SSJS Core library is used for certain Salesforce features, but I'm not sure which specific ones. I'll have to review my notes to make sure I get this right.

Hmm, I'm a bit confused about the difference between the trail files and the configuration files. I'll need to think this through carefully before selecting an answer.

I remember a practice question similar to this where we discussed the importance of aligning the divested entity with the overall strategy. Maybe option A is where we start?
