Anyone completed the CDE(Defender and Sentry) cert path for CyberArk?

If so, can you list/compare your previous certs and comparative skill level of the CDE path? Were study materials actually helpful or were they worthless (looking at you, CCNA Security Official Guide).

I?ve worked with CyberArk suite before but possible new position wants possession of or ability to get the cert. Want to make sure I?m not about to agree to some ridiculous cert that is niche and prides itself on minutiae without cause.

Thanks!
