Amazon Exam BDS-C00 Topic 6 Question 98 Discussion

Actual exam question for Amazon's BDS-C00 exam

Question #: 98
Topic #: 6

A social media customer has data from different data sources including RDS running MySQL, RedShift, and Hive on EMR. To support better analysis, the customer needs to be able to analyze data from different data sources and to combine the results.

What is the most cost-effective solution to meet these requirements?

ALoad all data from a different database/warehouse to S3. Use Redshift COPY command to copy data to Redshift for analysis.

BInstall Presto on the EMR cluster where Hive sits. Configure MySQL and PostgreSQL connector to select from different data sources in a single query.

CSpin up an Elasticsearch cluster. Load data from all three data sources and use Kibana to analyze.

DWrite a program running on a separate EC2 instance to run queries to three different systems. Aggregate the results after getting the responses from all three systems.

I'm leaning towards option D. Sure, it might require a bit more work, but having a dedicated program to query the different systems and aggregate the results could give us more control and flexibility. Plus, it's always fun to write your own code, am I right?

Hmm, I think option B is the way to go. Presto can query across different data sources without the need for data movement. Plus, it's probably the most cost-effective solution since we don't have to spin up any additional resources like EC2 or Elasticsearch.

I personally think option C could be a good solution. Setting up an Elasticsearch cluster and using Kibana for analysis might provide a more flexible approach.

I disagree, I believe option A is more cost-effective. Loading data to S3 and using Redshift COPY command for analysis seems simpler and efficient.

I think option B is the best solution. Installing Presto on the EMR cluster seems like a cost-effective way to analyze data from different sources.
