Objective 5.2
PMLEAutomating model retraining
Objective 5.2 sits in Automating and orchestrating ML pipelines, which carries 18% of the ML Engineer exam. The questions below are original, written from the official objective title above, and each explanation cites the Google Cloud page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A team pauses a nightly retraining schedule for a week and then resumes it. What decides whether the missed runs are submitted?
Correct.
Concept
A paused schedule leaves a hole, and there are two defensible things to do with it: pretend the time never passed, or make it up. Neither is always right, so the choice goes to whoever resumes.
Why B
A paused schedule does not create pipeline runs and can be resumed to become active again. On resuming, the catch_up parameter specifies whether skipped runs, the ones that would have been scheduled had the schedule been active, are rescheduled and submitted at the earliest possible schedule.
Source
Schedule a pipeline run with scheduler API, Agent Platform documentation, checked August 2026PAUSED : A paused schedule doesn't create pipeline runs. You can resume a paused schedule to make it active again. When you resume a paused schedule, you can use the catch_up parameter to specify whether skipped runs (runs that would have been scheduled if the schedule had been active) need to be rescheduled and submitted at the earliest possible schedule.
Now you: objective 5.2 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
An engineer creates a retraining schedule and leaves the end time unset. What happens once that schedule is running?
Sample question 2 of 3
A team reaches the end time configured on a pipeline schedule and checks the schedule state afterwards. Which state does it hold?
Sample question 3 of 3
A team copies a pipeline job request into a schedule template and includes an explicit job identifier in it. What does the scheduler do?
