With regards to the attached question, I disagree with the suggested answer and it’s mainly due to the use of the word “quickly” in the question itself. 😃 It’s not possible to quickly provision a Direct Connect connection (external dependenices on telco etc) and the question doesn’t mention that a DX connection already exists. We can’t assume one does. The question says “predictable data transfer” which does of course suggest a DX connection is the most suitable solution but, again, this goes against the “quickly” requirement.
Is there another way to interpret this (aside from assuming all the cables are already provisioned for a DX connection)?

Thank you for your feedback.
Looking at the other options,
“Utilize AWS Direct Connect Gateway for inter-region VPC access. Create a virtual private gateway in each VPC, then create a private virtual interface for each AWS Direct Connect connection to the Direct Connect gateway.”
Is the only option that fulfills the requirements on the question. A fast, dedicated private network link for each region VPC, with a predictable transfer performance. Direct Connect ticks all these boxes.
A VPN can’t satisfy the requirements because it traverses a normal internet connection, it is not a dedicated network link, and the network performance may not be consistent.
When you request for an AWS Direct Connect link, it can take up to 72 hours for AWS to review your request and provision a port for your connection. I believe this is still a quick turnaround given for data center scenarios.
I agree that the word “quickly” may add to the confusion for choosing the answer here. However, this is a professional-level exam question and AWS there is a certain level of difficulty from actual AWS exams that we try to mimic. AWS may throw some words in the question in order to add contradictions to your answers. Some questions do not explicitly show the obvious keywords and you have to assume some given best practices.
Anyway, our team will review this question for possible revision to properly get the point across.
Thank you again.
