I would select D. See AWS documentation: https://docs.aws.amazon.com/sagemaker/latest/dg/nbi-add-external.html

by excluding wrong options: A you might not have access to the EC2 instance => out B no automation => out C only the default kernel, which limits the DS => out => D

option D

D. https://docs.aws.amazon.com/sagemaker/latest/dg/nbi-add-external.html

Install custom environments and kernels on the notebook instance's Amazon EBS volume. This ensures that they persist when you stop and restart the notebook instance, and that any external libraries you install are not updated by SageMaker. To do that, use a lifecycle configuration that includes both a script that runs when you create the notebook instance (on-create) and a script that runs each time you restart the notebook instance (on-start).

Even the link given suggest Option D

Please ignore my previous comment, the answer is D

Key word here is how can the developer "guarantee"?? He guarantees that by including the install commands as part of the notebook. So, against the grain, I stand with B

D should be the answer

D "automatically" is the key here and using lifecycle configuration https://docs.aws.amazon.com/sagemaker/latest/dg/nbi-add-external.html

It is D, although is not even the best answer in my opinion. Although by default conda packages are installed in ephemeral storage, you can change that default behaviour. I did that in my last project and we created our own conda environment that persisted between shutdowns.

based on the refernce given under the answer its D not B

You can install packages using the following methods: 1-Lifecycle configuration scripts 2-Notebooks – The following commands are supported. %conda install %pip install 3-The Jupyter terminal – You can install packages using pip and conda directly.

NOT B ...>/etc/init contains configuration files used by Upstart. ANS...>D

Its for sure D
