Question 2

A machine learning specialist is developing a proof of concept for government users whose primary concern is security.The specialist is using Amazon SageMaker to train a convolutional neural network (CNN) model for a photo classifier application. The specialist wants to protect the data so that it cannot be accessed and transferred to a remote host by malicious code accidentally installed on the training container.Which action will provide the MOST secure protection?

Options :

A : Encrypt the weights of the CNN model.

B : Enable network isolation for training jobs.

C : Remove Amazon S3 access permissions from the SageMaker execution role.

D : Encrypt the training and validation dataset.

Answer: B

B : The problem involves complex and dynamic data.

C : The problem does not require scalability.

D : The problem requires simple logic.

Answer: B

Question 4

What makes delivering personalized recommendations challenging with traditional programming techniques?

Options :

A : It requires simple logic.

B : It does not require scalability.

C : It requires complex logic and responsiveness at scale.

D : It is easy to handle millions of requests per second.

Answer: C

Question 5

A company is deploying a new machine learning (ML) model in a production environment. The company is concerned that the ML model will drift over time, so the company creates a script to aggregate all inputs and predictions into a single file at the end of each day. The company stores the file as an object in an Amazon S3 bucket. The total size of the daily file is 100 GB. The daily file size will increase over time. Four times a year, the company samples the data from the previous 90 days to check the ML model for drift. After the 90-day period, the company must keep the files for compliance reasons. The company needs to use S3 storage classes to minimize costs. The company wants to maintain the same storage durability of the data. Which solution will meet these requirements?

Options :

A : Store the daily objects in the S3 One Zone-Infrequent Access (S3 One Zone-IA) storage class. Configure an S3 Lifecycle rule to move the objects to S3 Glacier Deep Archive after 90 days.

B : Store the daily objects in the S3 Standard-InfrequentAccess (S3 Standard-IA) storage class. Configure an S3 Lifecycle rule to move the objects to S3 Glacier Flexible Retrieval after 90 days.

C : Store the daily objects in the S3 Standard-InfrequentAccess (S3 Standard-IA) storage class. Configure an S3 Lifecycle rule to move the objects to S3 Glacier Deep Archive after 90 days.

D : Store the daily objects in the S3 One Zone-Infrequent Access (S3 One Zone-IA) storage class. Configure an S3 Lifecycle rule to move the objects to S3 Glacier Flexible Retrieval after 90 days.
