Question 1

You realize that your model deployment is about to reach its utilization limit. What would you do to avoid the issue before requests start to fail?

A. Update the deployment to add more instances. B. Reduce the load balancer bandwidth limit so that fewer requests come in. C. Update the deployment to use a larger virtual machine (mare CPUs/memory). D. Update the deployment to use fewer instances. E. Delete the deployment.

Question 2

As a data scientist, you create models for cancer prediction based on mammographic images.
The correct identification is very crucial in this case. After evaluating two models, you arrive at the following confusion matrix.
Model 1 has Test accuracy is 80% and recall is 70%.
* Model 2 has Test accuracy is 75% and recall is 85%.
Which model would you prefer and why?

A. Model 1, because the test accuracy is high. B. Model 1, because recall has lesser impact on predictions in this use case C. Model 2, because recall is high. D. Model 2, because recall has more impact on predictions in this use se.

Question 3

You have an embarrassingly parallel or distributed batch job on a large amount of data that you consider running using Data Science Jobs. What would be the best approach to run the workload?

A. Create a new job for every job run that you have to run in parallel, because the Data Science Jobs service can have only one job run per job. B. Reconfigure the job run because Data Science Jobs does not support embarrassingly parallel workloads. C. 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. D. Create the job in Data Science Jobs and then start the number of simultaneous jobs runs required for your workload.

Question 4

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

A. It changes the sensitivity of the model to detecting anomalies. B. It adds a score to each signal indicating the probability that its a false alarm. C. It is used to disable the reporting of false alarms. D. It determines how many false alarms occur before an error message is generated.

In addition to service job run environment variables, conda environment variables can be used in Data Science Jobs. D. The odac conda init command is used to configure the location of published conda environments. E. You can only create a published conda environment by modifying a Data Science conda environment.

Question 7

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

A. Key rotation reduces risk if a key is ever compromised. B. Periodically rotating keys limits the amount of data encrypted by one key version. C. Key rotation improves encryption efficiency. D. Periodically rotating keys make it easier to reuse keys. E. Key rotation allows you to encrypt no more than five keys at a time.

Question 8

Youare a data scientist working for a manufacturing company. You have developed a forecasting model to predict the sales demand in the upcoming months. You created a model artifact that contained custom logic requiring third party libraries. When you deployed the model, it failed to run because you did not include all the third party dependencies in the model artifact. What file should be modified to include the missing libraries?

A. model_artifact_validate.py B. runtime.yaml C. requirements.txt D. score.py
