Key constraints: Limited resources for DB admin and cost. 3rd party db features with privileged access. A: Won't work due to 3rd party features C: AMI with Oracle may work but again overhead of backed, maintenance etc D: Too much overhead in rewrite B: Actually supports Oracle 3rd party features Caution: If this is only about APEX as suggested in option D, then A is also a possible answer: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Appendix.Oracle.Options.APEX.html

"Amazon RDS Custom is a managed database service for applications that require customization of the underlying operating system and database environment. Benefits of RDS automation with the access needed for legacy, packaged, and custom applications." That should allow the "privileged access".

Migrate the database to Amazon RDS Custom for Oracle. Customize the database settings to support third-party features.

Custom database features = Amazon RDS Custom for Oracle

Most likely B.

RDS Custom since it's related to 3rd vendor RDS Custom since it's related to 3rd vendor RDS Custom since it's related to 3rd vendor

Option C is also a valid solution, but it is not as cost-effective as option B. Option C requires the company to manage its own database infrastructure, which can be expensive and time-consuming. Additionally, the company will need to purchase and maintain Oracle licenses.

RDS Custom enables the capability to access the underlying database and OS so as to configure additional settings to support 3rd party. This feature is applicable only for Oracle and Postgresql

I will say C cos of this "application uses third-party "

Should not it be since for Ec2, the company will have full control over the database and this is the reason that they are moving to AWS in the first place "The company plans to quickly migrate to AWS because of limited resources for the database, backup administration, and data center maintenance?"

RDS Custom when is something related to 3rd vendor, for me

not sure, but b probably
