Reveal correct answer
Correct answer: A
A. The CRON expression "5 * * * *" specifies that the function should execute at 5 minutes past every hour, every day of the week. The "*" wildcard character in the second and subsequent fields ensures that the function runs every hour, every day of the week, while the "5" in the first field specifies the 5th minute of each hour for execution.
B. The CRON expression "0/5 * * * *" specifies that the function should run every 5 minutes. This does not meet the requirement of executing the function at 5 minutes past every hour, every day of the week.
C.
The CRON expression "0 5 * * *" specifies that the function should execute at 5 hours past midnight (i.e. 5:00AM) every day. This expression does not meet the requirement of running the function at 5 minutes past every hour, every day of the week.
D. The CRON expression "5 * * * 1-5" specifies that the function should execute at 5 minutes past every hour, only on Monday to Friday. This expression does not meet the requirement of running the function every day of the week.
