Objective 2.3
PMLETracking and running ML experiments
Objective 2.3 sits in Collaborating within and across teams to manage data and models, which carries 16% 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 lead asks what the experiment tracking layer adds to the monthly bill on top of the training jobs themselves. What is charged?
Correct.
Concept
Tracking metadata is bookkeeping over work that is already metered. Charging for it again would penalise recording what happened, so the meter stays on the compute and storage the runs actually touch.
Why D
Experiment runs do not incur additional charges. You are charged only for the resources you use during the experiment, as described in the platform pricing.

Now you: objective 2.3 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
An engineer logs a validation loss at every training step and a final test accuracy once. Which metric kind holds the per step values?
Sample question 2 of 3
A team wants to know where the longitudinal training curves from an experiment run are physically kept. What holds them?
Sample question 3 of 3
A team associates a pipeline job with an experiment rather than with an existing experiment run. Where do that run's parameters and metrics come from?
