Actual exam question for Amazon's BDS-C00 exam

Question #: 96
Topic #: 9

A company has several teams of analytics. Each team of analysts has their own cluster. The teams need to run SQL queries using Hive, Spark-SQL and Presto with Amazon EMR. The company needs to enable a centralized metadata layer to expose the Amazon S3 objects as tables to the analysts.

Which approach meets the requirement for a centralized metadata layer?

AEMRFS consistent view with a common Amazon DynamoDB table

BBootstrap action to change the Hive Metastore to an Amazon RDS database

Cs3distcp with the outputManifest option to generate RDS DDL

Dnaming scheme support with automatic partition discovery from Amazon S3

D seems interesting, but not sure if it meets all requirements.

Wait, can we really use DynamoDB for this? Sounds odd.

I thought B could work too, but maybe not as well as A.

I vaguely remember something about naming schemes and partition discovery in S3, but I’m not confident if that’s the right approach for a centralized metadata layer.

I feel like s3distcp was mentioned in our study sessions, but I’m uncertain about how the outputManifest option fits into this scenario.

I think option B sounds familiar; changing the Hive Metastore to RDS was something we practiced, but I can't recall if it was the best choice for centralization.

I remember we discussed using EMRFS for consistent views, but I'm not entirely sure how it integrates with DynamoDB for metadata.

I'm leaning towards Option D with the automatic partition discovery from S3. That seems like it would be the most scalable and flexible approach for exposing the S3 objects as tables.

Option A with the EMRFS consistent view and a common DynamoDB table sounds like a good fit. That would provide a consistent way for the different teams to access the metadata across their clusters.

Hmm, I'm a bit confused by the different options here. I'll need to think through the pros and cons of each approach to determine which one is the most suitable for a centralized metadata layer.

This seems like a straightforward question about setting up a centralized metadata layer. I think the key is to find the approach that best meets the requirement of exposing the Amazon S3 objects as tables to the analysts.

Okay, I remember learning about this in class. I believe the key is that ISO 26000 is a guidance standard, not a certification standard like ISO 9001 or 14001. So the answer is C.

I'm leaning towards unit testing as the most effective option. Thorough unit testing can catch a lot of defects early in the development process before they propagate further. The other testing approaches are important too, but unit testing is really the foundation.

Ah, the age-old battle of centralized metadata versus distributed metadata. It's like trying to herd cats - you just never know which way they're going to go.

You know, if they really want to get creative, they could try creating a centralized metadata layer using interpretive dance and semaphore flags. That would definitely be a unique approach!

The naming scheme support with automatic partition discovery from Amazon S3 sounds like a convenient solution, but I'm not sure if it would offer the same level of control and consistency as the EMRFS approach.

Bootstrapping the Hive Metastore to an Amazon RDS database could also work, but it might add more complexity to the setup and maintenance.

The use of EMRFS consistent view with a common Amazon DynamoDB table seems like a straightforward approach to meet the requirement for a centralized metadata layer. It should provide a consistent view of the Amazon S3 objects across the different teams.
