Out of the two courses for SAA-C02, which one is most recent and updated?

This looks like the the newer one to me: https://acloud.guru/overview/certified-solutions-architect-associate

Although it’s really hard to tell. They should put dates on these things. I’m basing my guess on Alex Galvin having been at Cloud Guru more recently than the instructor in the other course–I looked them up on LinkedIn.

I used the previous course and passed the exam a couple of months ago.

Good luck!
