Episode 10. Mocks. Day 10 of your 10 day sprint.

Welcome to Power Day rehearsal. Three rounds, timed, no pauses. Say every answer with pick, first data, and trap ruled out.

Round one, DBA scenario. RAC node eviction during batch plus DataGuard lag on the same night. Understand: impact order, payments first. Prepare: CRS logs plus lag stats. Identify: the eviction cause before touching DataGuard; one incident at a time. Support: stabilize, catch up apply, write the combined runbook. Trap to name aloud: RAC equals HA without quorum detail.

Round two, job-fit case. The business wants four nines on payments with a fifteen minute RTO and zero RPO. Understand: what four nines excludes, usually planned maintenance. Prepare: cost of SYNC plus FSFO versus async plus wider RPO. Identify: recommend SYNC with standby redo and rehearsed failover, stating the latency cost honestly. Support: publish the RTO evidence from drills and the stay-fixed monitors.

Round three, behavioral STAR. Tell me about a time you did the right thing under pressure. Situation in two sentences. Task with I owned. Action longest. Result with a number plus the stay-fixed follow-through. Map it to Excellence or Do the Right Thing by name.

Say this bridge once in round two. Say: As integration lead I would deliver this incrementally with the product owner, each sprint adding one HA control with evidence.

Your Day 10 lab: run all three rounds timed, record yourself, then write a gap list of at most five items with owners.
Teaser: There is no next episode. Power Day is the next episode. Sleep, recite the spine, trust the reps.

Final drill. Say the one-sentence rule: state the pick, the first data, and the trap ruled out, in that order. Three times.

Close with the full intro spine and gap line, ninety seconds, no notes. Then repeat your weakest round answer three times aloud.

You did ten days of reps. Power Day is just one more rep. You are ready. Done.
