Zones were my weak spot on 1Z0-820. NerdExam fixed that.
SMF and service manifests are a larger chunk of the 1Z0-820 than I expected. The practice sets here drilled that domain well.
ZFS snapshots finally make sense. Cleared 1Z0-820 first try.
I have administered Solaris for years but the 1Z0-820 still caught me on newer features like unified archives and AI-based installation. The question bank here is solid, though a handful of items felt like they were testing edge cases I rarely see in practice. Worth doing regardless - it filled gaps I did not know I had.
