AWS Certified Data Analytics - Specialty Questions and Answers

Question 1

A software company hosts an application on AWS, and new features are released weekly. As part of the application testing process, a solution must be developed that analyzes logs from each Amazon EC2 instance to ensure that the application is working as expected after each deployment. The collection and analysis solution should be highly available with the ability to display new information with minimal delays.

Which method should the company use to collect and analyze the logs?

Options:

A.

Enable detailed monitoring on Amazon EC2, use Amazon CloudWatch agent to store logs in Amazon S3, and use Amazon Athena for fast, interactive log analytics.

B.

Use the Amazon Kinesis Producer Library (KPL) agent on Amazon EC2 to collect and send data to Kinesis Data Streams to further push the data to Amazon Elasticsearch Service and visualize using Amazon QuickSight.

C.

Use the Amazon Kinesis Producer Library (KPL) agent on Amazon EC2 to collect and send data to Kinesis Data Firehose to further push the data to Amazon Elasticsearch Service and Kibana.

D.

Use Amazon CloudWatch subscriptions to get access to a real-time feed of logs and have the logs delivered to Amazon Kinesis Data Streams to further push the data to Amazon Elasticsearch Service and Kibana.

Question 2

A company uses Amazon Elasticsearch Service (Amazon ES) to store and analyze its website clickstream data. The company ingests 1 TB of data daily using Amazon Kinesis Data Firehose and stores one day’s worth of data in an Amazon ES cluster.

The company has very slow query performance on the Amazon ES index and occasionally sees errors from Kinesis Data Firehose when attempting to write to the index. The Amazon ES cluster has 10 nodes running a single index and 3 dedicated master nodes. Each data node has 1.5 TB of Amazon EBS storage attached and the cluster is configured with 1,000 shards. Occasionally, JVMMemoryPressure errors are found in the cluster logs.

Which solution will improve the performance of Amazon ES?

Options:

A.

Increase the memory of the Amazon ES master nodes.

B.

Decrease the number of Amazon ES data nodes.

C.

Decrease the number of Amazon ES shards for the index.

D.

Increase the number of Amazon ES shards for the index.

Question 3

A company's data science team is designing a shared dataset repository on a Windows server. The data repository will store a large amount of training data that the data

science team commonly uses in its machine learning models. The data scientists create a random number of new datasets each day.

The company needs a solution that provides persistent, scalable file storage and high levels of throughput and IOPS. The solution also must be highly available and must

integrate with Active Directory for access control.

Which solution will meet these requirements with the LEAST development effort?

Options:

A.

Store datasets as files in an Amazon EMR cluster. Set the Active Directory domain for authentication.

B.

Store datasets as files in Amazon FSx for Windows File Server. Set the Active Directory domain for authentication.

C.

Store datasets as tables in a multi-node Amazon Redshift cluster. Set the Active Directory domain for authentication.

D.

Store datasets as global tables in Amazon DynamoDB. Build an application to integrate authentication with the Active Directory domain.
