I would say yes for your first question but keep in mind, even for issuers, if there is a better answer than understanding internal control, you should choose it. That's why I asked you if you have all four answers. Again, if you compare understanding of internal control to inquire the entity’s attorney, it's seems the former would need less work than a confirmation besides it's within the entity itself, so I think that's why you got it wrong.
About examination, you can use it for services including prospective FS, Pro forma FS, Internal control, Compliance, and MD&A. Review(in SSAE) can be only for pro forma and MD&A. Agreed upon procedures can be for prospective FS, internal control and compliance. Compilation (using SSAE) only for prospective FS.
To differ examination from audit, review, and compilation, think of it this way (more work to less work to do)
1-Audit (issue opinion)
2- Examination (positive assurance)
3- Review (negative assurance) –
4- Compilation and Agreed upon procedures – Do not express opinion (and indicate that in your report)
I hope that helps
