Creating PDF/A with linked attachments

[LostinHelsinki]

Please help!

I have a word document where I have attached linked PDFs and they work perfectly fine when you click them open - in Word. When I create PDF/A (required from school) from the Word file, the links disappear. My understanding is that it is possible to create links to PDF afterwards, but the PDF/A form will not stay in the original format. And only the Adobe Pro version will be able to create these in edit mode - right?

In the linked instructions the advice isn't quite up to date, does anyone have some updated guide on how to add linked PDFs? And will they be visible to whomever the document (created from Word) is sent to?

One last question:

And will only other Adobe Pro programs be able to click on the links or will it work on all Adobe programs?

Can you confirm why you export your Word doc as a PDF/A ? 

Is that a requirement from your school?

[LostinHelsinki]

Yes, the Thesis must be returned in PDF/A - unfortunately.

What version of PDF/A ?

 This is Finnish, but the selections are here that apply according to our instructions.

PDF/A-1, PDF/A-2, or PDF/A-3 ?

[LostinHelsinki]

I have no clue. What is the difference between those?

There are no more specified requirements for the PDF/A type. Only to use the instructions as shown in the picture I attached earlier. But actually these are the questions that need answering the most:

1. In the linked instructions the advice isn't quite up to date, does anyone have some updated guide on how to add linked PDFs? And will they be visible to whomever the document (created from Word) is sent to?

2. Will only other Adobe Pro programs be able to click on the links or will it work on all Adobe programs?

I don't know what the picture show.

This is the only instructions from school, to export as PDF/A and choose the following options:
