Correct Answer: D

Question 2

You are working as a data scientist for a healthcare company. They decide to analyze the data to find patterns in a large volume of electronic medical records. You are asked to build a PySpark solution to analyze these records in a JupyterLab notebook. What is the order of recommended steps to develop a PySpark application in Oracle Cloud Infrastructure (OCI) Data Science?

A. Configure core-site.xml. Install a PySPark conda environment. Create a Data Flow application with the Accelerated Data Science (ADS) SDK Develop your PySpark ap-plication. Launch a notebook session.

B. Develop your PySpark application Create a Data Flow application with the Ac-celerated Data Science (ADS) SOK

C. Develop your PySpark application. Create a Data Flow application with the Ac-celerated Data science (ADS) SDK.

D. Install a spark conda environment. Configure core-site.xml. Launch a notebook session: Create a Data Flow application with the Accelerated Data Science (ADS) SOK. Develop your PySpark application

E. Launch a notebook session. Configure core-site.xml. Install a PySPark conda environ-ment.

F. Launch a notebook session. Install a PySpark conda environment. Configure coresite. xml.

Correct Answer: C

Question 3

Which TWO statements are true about published conda environments?

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

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

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

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

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

Correct Answer: A,B

Question 4

You are attempting to save a model from a notebook session to the model catalog by using the Accelerated Data Science (ADS) SDK, with resource principal as the authentication signer, and you get a 404 authentication error. Which TWO should you look for to ensure permissions are set up correctly?

A. The dynamic group's matching rule exists for notebook sessions in this compartment.

B. The model artifact is saved to the block volume of the notebook session.

C. The policy for the dynamic group grants manages permissions for the model catalog in this compartment.

D. The networking configuration allows access to the Oracle Cloud Infrastructure (OCI) services through a Service Gateway.

E. The policy for your user group grants manage permissions for the model catalog in this compartment.

Correct Answer: C,E

Question 5

You want to ensure that all stdout and stderr from your code are automatically collected and logged, without implementing additional logging in your code. How would you achieve this with Data Science Jobs?

A. Make sure that your code is using the standard logging library and then store all the logs to Check Storage at the end of the job.

B. Data Science Jots does not support automatic fog collection and storing.

C. You can implement custom logging in your code by using the Data Science Jobs logging.

D. On job creation, enable logging and select a log group. Then, select either log or the op-tion to enable automatic log creation.

Correct Answer: C

Question 6

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.?

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

B. Key rotation reduces risk if a key is ever compromised.

C. Periodically rotating keys make it easier to reuse key.

D. Key rotation improves encryption efficiency.

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

Correct Answer: B,C
