AWS Certified Data Engineer Associate DEA-C01 Practice Question

A data engineer must catalog tables from an Amazon RDS for MySQL database that sits in a private subnet with no NAT or internet gateway. The engineer is creating a new AWS Glue crawler to read the schema. Which configuration will allow the crawler to reach the database without exposing it publicly or adding extra network infrastructure?

  • Create a network connection that uses a public subnet with an internet gateway so the crawler can reach the database over its public endpoint.

  • Do not create any connection; selecting Amazon RDS as the data store is sufficient because Glue can connect to all regional RDS endpoints by default.

  • Create a JDBC AWS Glue connection that specifies the RDS endpoint, references credentials in AWS Secrets Manager, and selects the same VPC, private subnet, and a security group allowing port 3306.

  • Create a JDBC connection with the default Glue security group; the crawler will automatically route through the account's NAT gateway.
