Technical - Situational

1. I have a choice to make a web frontend integrate using a graphQL API or a REST API. Which one is better for long term maintenance of the application?
2. I can integrate 2 different systems: either point-to-point or hub-and-spoke, or I can use a bus. What are the pro's and cons of each?
3. What is a canonical API?
4. I have 2 systems that integrate currently using dropped files. How would fix that? Should I fix it? What does it mean?
5. I have a system that receives all of its input through EDI & I want to transit that system to one that is near real time. What infrastructure should I put in?
6. I want to put an API interface onto my web services that are made available through either Azure or AWS. What is the necessary component that I should aquire from my cloud service provider in order to protect those API's from malware?
7. I want to decide whether I should be using a relational database or a NoSQL database. Give the pro's and con's which one is faster for writing?
