Question 1

Multiple choice

You are preparing a configuration object necessary to create a Data Flow application.

Which THREE parameter values should you provide?

The path to the arhive.zip file.

The local path to your pySpark script.

The compartment of the Data Flow application.

The bucket used to read/write the pySpark script in Object Storage.

The display name of the application.

Question 2

Multiple choice

You are a data scientist leveraging Oracle Cloud Infrastructure (OCI) Data Science to create a model and need some additional python libraries for processing genome sequencing data.

Which of the following THREE statements are correct with respect to installing additional Python libraries to process the data?

You cannot install a library that's not preinstalled in the provided image

You can only install libraries using yum and pip as a normal user

OCI Data Science allows privileges in notebook sessions.

You can install any open source package available in a publicly accessible Python Package Index (PyPI) repository

You can install private or custom libraries from your own internal repositories

Question 3

Single choice

You have trained three different models on your data set using Oracle AutoML. You want to visualize the behavior of each of the models, including the baseline model, on the test set.

Which class should be used from the Accelerated Data Science (ADS) SDK to visually compare the models?

ADS Explainer

ADS Evaluator

ADSTuner

EvaluationMetrics

Question 4

Single choice

While reviewing your data, you discover that your data set has a class imbalance. You are aware that the Accelerated Data Science (ADS) SDK provides multiple built-in automatic transformation tools for data set transformation.

Which would be the right tool to correct any imbalance between the classes?

sample()

suggeste_recoomendations()

auto_transform()

visualize_transforms()

Question 5

Single choice

Which feature of the Oracle Cloud Infrastructure (OCI) Vision service helps you generate in-dexing tags for a collection of marketing photographs?

Document classification

Image classification

Text recognition

Key Value extraction

Question 6

Single choice

During a job run, you receive an error message that no space is left on your disk device. To solve the problem, you must increase the size of the job storage.

What would be the most effi-cient way to do this with Data Science Jobs?

On the job run, set the environment variable that helps increase the size of the storage.

Your code using too much disk space. Refactor the code to identify the problem.

Edit the job, change the size of the storage of your job, and start a new job run.

Create a new job with increased storage size and then run the job.

Question 7

Multiple choice

You are a data scientist using Oracle AutoML to produce a model and you are evaluating the score metric for the model.

Which of the following TWO prevailing metrics would you use for evaluating multiclass classification model?

Recall

Mean squared error

F1 Score

R-Squared

Explained variance score

Question 8

Multiple choice

Select two reasons why it is important to rotate encryption keys when using Oracle Cloud In-frastructure (OCI) Vault to store credentials or other secrets.
?

Key rotation allows you to encrypt no more than five keys at a time.

Key rotation reduces risk if a key is ever compromised.

Key rotation improves encryption efficiency.

Periodically rotating keys make it easier to reuse key.

Periodically rotating keys limits the amount of data encrypted by one key version.

Question 9

Single choice

Using Oracle AutoML, you are tuning hyperparameters on a supported model class and have specified a time budget. AutoML terminates computation once the time budget is exhausted.

What would you expect AutoML to return in case the time budget is exhausted before hy-perparameter tuning is completed?

A hyperparameter configuration with a minimum learning rate is returned.

The current best-known hyperparameter configuration is returned.

A random hyperparameter configuration is returned.

The last generated hyperparameter configuration is returned.

Question 10

Single choice

You have developed a model training code that regularly checks for new data in Object Storage and retrains the model.

Which statement best describes the Oracle Cloud Infrastructure (OCI) services that can be accessed from Data Science Jobs?

Data Science Jobs can access OCI resources only via the resource principal.

Some OCI services require authorizations not supported by Data Science Jobs.

Data Science Jobs cannot access all OCI services.

Data Science Jobs can access all OCI services.
