Exam DBDEA Topics: jobs Difficulty: easy

A daily Lakeflow Job must fire at 06:00 in the company's Sao Paulo office (America/Sao_Paulo). The platform team in Paris created the schedule, so its timezone is Europe/Paris and its cron fires at 11:00 — 06:00 in Sao Paulo during the European summer. In late October, Europe ended daylight saving time, and the job began firing at 07:00 local. How does the team make the firing time deterministic?

  1. A. Set the schedule's timezone to America/Sao_Paulo, so the cron is always resolved in Sao Paulo time
  2. B. Keep Europe/Paris and edit the cron hour by hand twice a year, when European clocks change
  3. C. Set spark.sql.session.timeZone to America/Sao_Paulo in the job's tasks, so the scheduler fires in local time
  4. D. Leave the timezone alone, because a job's cron automatically follows the local timezone of the engineer who created it
