I found this certification to be quite difficult .[More than Solution Architect Professional]

As of now there are 18 questions I am adding more questions daily.

 

This is a  sectional test for Data Analytics

  • The questions are with similar difficulty levels with the Speciality  exam.
  • Please try to find the answer on your own
  • There some really updated service related questions
  • I have not kept any question questions from professional level but this can really help for that level
  • If you want a time-bound quiz with exact difficulty check for the practice test sets

For any help, you can reach out to me at [email protected]

1. Your company has newly acquired a company that has an in-house PostgreSQL with several tables all having an indexed Timestamp column. As a data architect, you need to make sure you integrate this with your existing Datawarehousing Solution which runs on Redshift as a staging layer. The business has given a  requirement of having a data lag of a maximum of 3 hours. What is the most optimal way to achieve this?

2. There is an AWS Batch application that drops a file in excess of 50 GB into an S3 bucket and another batch application picks this file up and stores in Redshift. The size of the data is increasing daily and you can see the data loading is getting slow day by day. Which is the optimization technique that you should take to remove this slowness?

3. You are responding to a business requirement that has been floated by your client. Your client is having data in various data sources CSVs stored in S3, Logfiles files stored in S3, some structured data stored in Redshift. What business solution you should propose to your client which can give him an analytical Dashboard in the most cost-optimal way and in minimal time?

4. Choose the best option to create a real-time replica for a Redshift cluster.

5. A large eCommerce company is using historical search data to create a recommendation engine. The data is fairly consistent apart from some predictable surge during sales. What is the best possible cost-effective solution to come up with the solution?

6. You need to analyze AWS cloud trial logs data which are stored in the S3 bucket, which is the best and most cost-effective way to analyze these logs using Athena.

7. Due to some regulatory requirements, one of the health care clients of yours needs to make sure they back up their encrypted Dataware housing solution which is built in Redshift to a different region. What is the easiest way to implement this making sure the solution preserves the encryption at rest and in transit?

8. Your client installed an elastic search node into their VPC. You have been employed as a cloud security consultant and your job is to secure the connection between any third-party service and elastic search node. What is the possible solution you can implement? CHOOSE TWO.

9. You have got a ticketing application that puts the tickets dumps in the S3 bucket on a daily basis but in irregular time. The volume of the ticket dump is also not constant. The data dropped in S3 needs some transformation before being sent to the Elasticsearch cluster. What is the solution you will implement so that you can put these data in an Elastic Search cluster with minimum maintenance and maximum scalability?

10. You are creating a sensor monitoring system that reads the sensor (which is installed in power plants ) data and logs them in Amazon S3. What the system you will build which will read this data in a continuous manner and report any anomaly or unpredictable behavior is detected in the data that will be most easily implementable.

11. You have created a real-time IoT monitoring system. The sensors send the data in a Kenesis stream and then Lambda function reads the data from the streams and persist them into Dynamo DB table. You are using chard.js to create the dashboard for the system. It is observed that in peak time you are losing some data, which can be a possible cause. You are sure that you have allocated enough shards and read and write capacities. What can be possible causes for this situation? CHOOSE ALL THAT APPLY

12. Because of GDPR compliance, you need to make sure the data your Redshift cluster is analyzing is residing in an S3 bucket that belongs to another AWS account and in a different Region. How can you configure your system to achieve this solution?

13. Being a  data analysis manager of an e-commerce company you are looking at the shipment related data. These data are of multidimensional deals with day to shipment, cost of the product, shipment cost, category, destination, season e.t.c. You need to see how the cost of shipping is varying with the destination. What kind of Quicksight chart will be the best suite for this analysis?

14. Being a  data analysis manager of an e-commerce company you are looking at the shipment related data. These data are of multidimensional deals with day to shipment, cost of the product, shipment cost, category, destination, season e.t.c. You need to find out different trends and outliers from the data, what Quicksight visualization chart you will be using?

15. You are working as a solution architect in an online streaming music app company. The present architecture is using apache spark to make some digital filters on top of audio streams that are consumed using on-prem Apache Kafka and then they are stored in S3. You want to migrate the entire echo system to Amazon web service, which will be the best approach for this?

18. You have multiple sensors sending the data from a medical device that monitors some human vitals as part of some specific medical condition investigation. The data coming from the sensors takes approximately two minutes to get analyzed and then sent to some analysis dashboard. The number of sensors sending the data and the data packet load is not constant and there is no predictable load of the data to be analyzed. What will be the best solution for this kind of situation?
