Explanation
The question states "The database must not be accessible from the Internet, but the cluster must be able to retrieve software updates from the Internet."
Therefore, the database must be located in a private subnet. However, since an Internet connection is required to receive software updates, a separate public subnet should be created. Then, to connect to the Internet from the private subnet, it is common to connect to the Internet via a NAT gateway located in the public subnet.
