Objective 2.2
PMLEModel prototyping using notebooks
Objective 2.2 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 finance lead asks why managed notebook instances stop on their own overnight with nobody acting on them. What is the default behaviour?
Correct.
Concept
An interactive workspace bills for the machine rather than for the work, so idle time is pure cost. Making the shutdown a default rather than an option is how a platform stops that cost accruing by accident.
Why C
To help manage costs, notebook instances shut down after being idle for a specific time period by default. The amount of time can be changed, and the feature can also be turned off.

Now you: objective 2.2 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
A team needs an older TensorFlow release and an R kernel on a notebook instance that ships with neither of them. What supplies both?
Sample question 2 of 3
An engineer plans to build a notebook instance image starting from an unrelated public Python base image. What does the guidance say about that?
Sample question 3 of 3
A team runs notebook instances inside a service perimeter and plans to schedule notebook runs from them. Which limitation applies there?

These are the official pages the questions above cite. Reading them is studying the objective from the primary source, which is what the explanations point you toward anyway.
