The EDPT and how it will affect me

I was told by my recruiter that I have to take the EDPT in order to proceed forward with the jobs i have listed. I don't have to pass but, I have to at least make an attempt. None of my jobs require it and I was told it won't affect anything. I'm just curious how true this is. I believe that it might not affect it but why do I need to take it in the first place? If I completely bomb it will that be a factor they look at when selecting me a job even though the job doesn't require it? I can see them thinking I might not be qualified if I don't do well on it. For reference I'm dual tracking space and air and most of my jobs are Cyber and Intel though again none of them require the EDPT.
