Amazon Web Services Data-Engineer-Associate Exam With Confidence Using Practice Dumps

According to the guide:

“For integrating streaming data from Amazon MSK into Amazon Redshift efficiently and cost-effectively, AWS Glue streaming jobs can process and transform the data, storing it in Amazon S3. Amazon Redshift Spectrum can then directly query the data from S3, minimizing operational overhead and reducing storage costs.”

This setup offers:

Low latency via Glue streaming.

Low storage cost by using Parquet/ORC on S3.

Minimal operational overhead by avoiding complex pipelines or constantly updated materialized views.

Problem Analysis:

The company needs cross-account access to allow QuickSight in BI-Account to interact with an S3 bucket in Hub-Account.

The bucket is encrypted with an AWS KMS key.

Appropriate permissions must be set for both S3 access and KMS decryption.

Key Considerations:

QuickSight requires IAM permissions to access S3 data and decrypt files using the KMS key.

Both S3 and KMS permissions need to be properly configured across accounts.

Solution Analysis:

Option A: Use Existing KMS Key for Encryption

While the existing KMS key is used for encryption, it must also grant decryption permissions to QuickSight.

Option B: Add S3 Bucket to QuickSight Role

Granting S3 bucket access to the QuickSight service role is necessary for cross-account access.

Option C: AWS RAM for Bucket Sharing

AWS RAM is not required; bucket policies and IAM roles suffice for granting cross-account access.

Option D: IAM Policy for KMS Access

QuickSight’s service role in BI-Account needs explicit permissions to use the KMS key for decryption.

Option E: Add KMS Key as Resource for Role

The KMS key must explicitly list the QuickSight role as an entity that can access it.

Implementation Steps:

S3 Bucket Policy in Hub-Account:Add a policy to the S3 bucket granting the QuickSight service role access:

json

{

" Version " : " 2012-10-17 " ,

" Statement " : [

{

" Effect " : " Allow " ,

" Principal " : { " AWS " : " arn:aws:iam:: < BI-Account-ID > :role/service-role/QuickSightRole " },

" Action " : " s3:GetObject " ,

" Resource " : " arn:aws:s3::: < Bucket-Name > /* "

}

]

}

KMS Key Policy in Hub-Account:Add permissions for the QuickSight role:

{

" Version " : " 2012-10-17 " ,

" Statement " : [

{

" Effect " : " Allow " ,

" Principal " : { " AWS " : " arn:aws:iam:: < BI-Account-ID > :role/service-role/QuickSightRole " },

" Action " : [

" kms:Decrypt " ,

" kms:DescribeKey "

],

" Resource " : " * "

}

]

}

IAM Policy for QuickSight Role in BI-Account:Attach the following policy to the QuickSight service role:

{

" Version " : " 2012-10-17 " ,

" Statement " : [

{

" Effect " : " Allow " ,

" Action " : [

" s3:GetObject " ,

" kms:Decrypt "

],

" Resource " : [

" arn:aws:s3::: < Bucket-Name > /* " ,

" arn:aws:kms: < region > : < Hub-Account-ID > :key/ < KMS-Key-ID > "

]

}

]

}

Setting Up Cross-Account S3 Access

AWS KMS Key Policy Examples

Amazon QuickSight Cross-Account Access

To create a new table named cities_usa in Amazon Athena based on a subset of data from the existing cities_world table, you should use an INSERT INTO statement combined with a SELECT statement to filter only the records where the country is ' usa ' . The correct SQL syntax would be:

Option A: INSERT INTO cities_usa (city, state) SELECT city, state FROM cities_world WHERE country= ' usa ' ;This statement inserts only the cities and states where the country column has a value of ' usa ' from the cities_world table into the cities_usa table. This is a correct approach to create a new table with data filtered from an existing table in Athena.

Options B, C, and D are incorrect due to syntax errors or incorrect SQL usage (e.g., the MOVE command or the use of UPDATE in a non-relevant context).
