Welcome to your interview.
The question is on your right: TCP Connection Establishment and Troubleshooting. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Explain the step-by-step process of how a computer establishes a TCP connection and how you would troubleshoot a connection failure at the transport layer.
