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. Key rotation improves encryption efficiency.

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

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

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?

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

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

C. Data Science Jobs cannot access all OCI services.

D. Data Science Jobs can access all OCI services.

Which Oracle Accelerated Data Science (ADS) classes can be used for easy access to data sets from reference libraries and index websites, such as scikit-learn?

A. ADSTurner

B. DatasetFactory

C. SecretKeeper

D. Dataset Browser

You are asked to prepare data for a custom-built model that requires transcribing Spanish video recordings into a readable text format with profane words identified. Which Oracle Cloud service would you use?

A. OCI Translation

B. OCI Language

C. OCI Anomaly Detection

D. OCI Speech

You are given the task of writing a program that sorts document images by language. Which Oracle AI service would you use?

A. Oracle Digital Assistant

B. OCI Speech

C. OCI Vision

D. OCI Language

You have an embarrassingly parallel or distributed batch job on a large amount of data running using Data Science Jobs

What would be the best approach to run the workload?

A. Create the job in Data Science Jobs and then start the number of simultaneous job runs required for your workload.

B. Create the job in Data Science Jobs and start a job run. When it is done, start a new job run until you achieve the number of runs required.

C. Reconfigure the job run because Data science jobs does not support embarrassingly parallel.

D. Create a new job for every job run that you have to run in parallel, because the Date Science Jobs service can have only one job run per job.

You are using Oracle Cloud Infrastructure Anomaly Detection to train a model to detect anomalies in pump sensor data. How does the required False Alarm Probability settings affect an anomaly detection model?

A. It changes the sensitivity of the model to detect anomalies.

B. It is used to disable the reporting of false alarm.

C. It Adds a score to each signal indicating the probability that it is false alarm.

D. It determines how many false alarms occur before an error message is generated.
