Which of the following scenarios would necessitate the use of UDP's optional checksum field for data integrity, even if the underlying network layer (e.g., IPv4) also provides a checksum?
Question 2
A custom streaming protocol is being designed for a live event broadcast where minimal delay is paramount, and occasional frame drops are acceptable. The developers choose UDP as the transport layer protocol. What is the most significant challenge they must address at the application layer due to this choice?
Question 3
Consider a network application that uses UDP for communication. If the application sends a datagram larger than the network's Maximum Transmission Unit (MTU), what is the likely consequence, and how is it typically handled?
Question 4
A network device is configured to perform Network Address Translation (NAT). An internal host initiates a UDP communication to an external server. Which of the following is crucial for the NAT device to correctly forward the response datagram from the external server back to the internal host?
Question 5
In a scenario where a client application needs to discover available services on a local network using broadcast messages, why is UDP inherently more suitable than TCP for this task?
