C D E tbh, but if I'm missing something shout it out.
Mock exams and Oracle docs cover this. Anyone else see C, D, E always listed as required?
C. D, E imo. The key here is that both primary and the FSFO target standby need Flashback Database enabled, not just the primary (so A's out). Also, synchronous redo applies in Maximum Availability mode, so D is needed. For B, async redo is fine in Max Performance but is not a hard prerequisite for FSFO itself. Pretty sure that's what Oracle docs say-let me know if you see it differently.
C/D/E makes sense, but not totally sure since sometimes Oracle throws curveballs with these. The requirement for Flashback on both sides plus synchronous redo in Max Availability matches docs, I think. If someone has different experience with FSFO prereqs, curious to hear it.
C/D/E? Pretty sure, but since B relates to Max Performance, might be missing something.
C D, E. B looks tempting but that's a trap for Maximum Performance mode only. Seen similar on past exams, so pretty sure this is the right pick but open if someone has Oracle docs saying otherwise.
C D E tbh, but notice if the config was set to Max Performance instead of Max Availability, option B could sneak in. Oracle gets picky about sync vs async redo depending on mode.
B, not A. C D E all the way for real FSFO prereqs.
Ugh, Oracle always making you memorize which exact modes trigger which prereqs for FSFO. Why is it always the Flashback and sync redo ones?
I don’t think it’s A. C, D, E are the ones you need-static service isn’t a core prerequisite for FSFO, that’s a common mix-up. Flashback has to be on for both primary and standby, and sync redo's a must for Max Availability mode. B sounds tempting, but async redo is just an option in Max Performance, not a requirement. Pretty sure about this but open to corrections if I missed some edge case.
Be respectful. No spam.
