This time you can test your understanding of networking questions discussed in this chapter by answering the following questions:
- If, in the UDP protocol, there is no guarantee that the packet will arrive at the destination, why do we bother with it at all?
- How can we enable a network cache in Qt? What will get cached there?
- What is the IP protocol?
- Is there a Qt cache for DNS? How can we use it?
- Why would you consider using HTTP/2?
- What HTTP-like protocols are supported by Qt? Is REST supported?
- What are some examples of well-known ports? What are they, anyway?
- Ever heard of OSI's 7-layers protocol stack model?
- What are the performance gains from reusing a TCP connection?
- What is the TLS protocol? Isn't it the same as SSL?
