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?

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

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

C. OCI Data Science allows privileges in notebook sessions.

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

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

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?

A. sample()

B. suggeste_recoomendations()

C. auto_transform()

D. visualize_transforms()

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

A. Document classification

B. Image classification

C. Text recognition

D. Key Value extraction

You are creating an Oracle Cloud Infrastructure (OCI) Data Science job that will run on a recurring basis in a production environment. This job will pick up sensitive data from an Object Storage bucket, train a model, and save it to the model catalog. How would you design the authentication mechanism for the job?

A. Package your personal OC file and keys in the job artifact.

B. Use the resource principal of the job run as the signer in the job code, ensuring there is a dynamic group for this job run with appropriate access to Object Storage and the model catalog.

C. Store your personal OCI config file and kays in the Vault, and access the Vault through the job nun resource principal

D. Create a pre-authenticated request (PAA) for the Object Storage bucket, and use that in the job code.

You have received machine learning model training code, without clear information about the optimal shape to run the training on. How would you proceed to identify the optimal compute shape for your model training that provides a balanced cost and processing time?

A. Start with the strangest compute shape Jobs support and monitor the Job Run metrics and time required to complete the model training. Tune the model so that it utilizes as much compute resources as possible, even at an increased cost.

B. Start with a random compute shape and monitor the utilization metrics and time required to finish the model training Perform model training optimizations and performance tests in advance to identify the right compute shape before running the model training as a job.

C. Start with a smaller shape and monitor the Job Run metrics and time required to complete the model training: If the compute shape is not fully utilized, tune the model parameters, and rerun the job. Repeat the process until the shape resources are fully utilized.

D. Start with a smaller shape and monitor the utilization metrics and time required to complete the model training. If the compute shape is fully utilized, change to compute that has more resources and re-run the job. Repeat the process until the processing time does not improve.

Six months ago, you created and deployed a model that predicts customer churn for a call center. Initially, it was yielding quality predictions. However, over the last two months, users have been questioning the credibility of the predictions. Which TWO methods customer churn would you employ to verify the accuracy of the model?

A. Redeploy the model

B. Retrain the model

C. Operational monitoring

D. Validate the model using recent data

E. Drift monitoring

You are a data scientist leveraging the Oracle Cloud Infrastructure (OCI) Language AI service for various types of text analyses. Which TWO capabilities can you utilize with this tool?

A. Table extraction

B. Punctuation correction

C. Sentence diagramming

D. Topic classification

E. Sentiment analysis

You are a data scientist with a set of text and image files that need annotation, and you want to use Oracle Cloud Infrastructure (OCI) Data Labeling. Which of the following THREE an-notation classes are supported by the tool.?

A. Object Detection

B. Named Entity Extraction

C. Classification (single/multi label)

D. Key-Point and Landmark

E. Polygonal Segmentation

F. Semantic Segmentation

Which TWO statements are true about published conda environments?

A. The odsc conda init command is used to configure the location of published conda en- vironments.

B. They can be used in Data Science Jobs and model deployments.

C. Your notebook session acts as the source to share published conda environment with team members.

D. You can only create published conda environment by modifying a Data Science conde

E. They are curated by Oracle Cloud Infrastructure (OCI) Data Science.

The feature type TechJob has the following registered validators: Tech- Job.validator.register(name='is_tech_job', handler=is_tech_job_default_handler) Tech- Job.validator.register(name='is_tech_job', handler= is_tech_job_open_handler, condi- tion=(`job_family',)) TechJob.validator.register(name='is_tech_job', handler= is_tech_job_closed_handler, condition=(`job_family': `IT')) When you run is_tech_job(job_family='Engineering'), what does the feature type validator system do?

A. Execute the is_tech_job_default_handler sales handler.

B. Throw an error because the system cannot determine which handler to run.

C. Execute the is_tech_job_closed_handler handler.

D. Execute the is_tech_job_open_handler handler.
