Hi Stresco,
Thank you for your posting here. After reviewing the options, I can confirm that all of them are correct and distinct from each other. However, please take note that the first option specifies to configure the “DB_Host” environment variable with the hostname of the Aurora database instance endpoint, while the other option instructs to configure it with the hostname of the Aurora database cluster endpoint.
Therefore, one of the correct answers is the option “Ensure that the “DB_HOST” environment variable is configured with the hostname of the Aurora database cluster endpoint.” since this is the main endpoint that accepts read/write connections.
Hope this clarifies any confusion.
