AWS Certified Database – Specialty — Question 44

A Database Specialist is creating a new Amazon Neptune DB cluster, and is attempting to load data from Amazon S3 into the Neptune DB cluster using the
Neptune bulk loader API. The Database Specialist receives the following error:
`Unable to connect to s3 endpoint. Provided source = s3://mybucket/graphdata/ and region = us-east-1. Please verify your
S3 configuration.`
Which combination of actions should the Database Specialist take to troubleshoot the problem? (Choose two.)

Answer options

• A. Check that Amazon S3 has an IAM role granting read access to Neptune
• B. Check that an Amazon S3 VPC endpoint exists
• C. Check that a Neptune VPC endpoint exists
• D. Check that Amazon EC2 has an IAM role granting read access to Amazon S3
• E. Check that Neptune has an IAM role granting read access to Amazon S3

Correct answer: B, E

Explanation

The correct actions are to ensure that an Amazon S3 VPC endpoint exists (B) and that Neptune has an IAM role granting read access to Amazon S3 (E). The absence of a VPC endpoint could prevent communication between Neptune and S3, while the IAM role is necessary for Neptune to access the S3 bucket. The other options do not directly address the connection issue indicated in the error message.
