This sequence is based on the project's README.md's sequence.
Data durability and recovery
1. SUBMIT screenshots of both VPCs after they are created
Highly durable RDS Database
1. SUBMIT screenshot of the configuration of the primary and read replica database after they are created
Since, it was not clear, which configuration it was asking, so I have taken multiple screenshots
2. SUBMIT screenshot of the configuration of the database subnet groups as well as the route tables associated with those subnets
Subnet Groups
Note: I didn't notice but I have given the same name to subnets in both Primary and Read Replica, it is obviously not creating any issues, but I am just clearing it in case, it creates any confusion.
Route Tables

1. SUBMIT your answers

1. SUBMIT log of connecting to the database and running the above commands
Monitor database
1. SUBMIT screenshot of the DB Connections and the database replication configuration
Simulate recovery in standby region

2. SUBMIT screenshots of the database configuration before and after the database promotion
