For this module, the accessibility concerns are the alternate text for the image and the text used for the button. Normally, these concerns would be address separately, but because we made the entire module a link (hover over any part of the module and click to activate the button link), the accessibility concerns are eased a bit.
If the image was removed, a sighted user would not be missing content, so the alternate text field may be left blank.
Given that the title and blurb are sufficiently descriptive, the button text, which normally would be consider ambiguous (learn more about what?), is fine. Again, we are allowed to use ambiguous text for the button only because the entire module is the link text.
Because the image includes text, you should use that text as the alternative text. If, however, that text or its equivalent is in the title or blurb, then you should leave the alternate text field blank. To decide if you need to include the alternate text or not, ask yourself if a sighted user would be missing any content if the image were not present. If the answer is yes, then include the alternate text.
Note that the button text is this example is quite descriptive. Using descriptive text for buttons and links is always the best practice.
