A network engineer is designing a system that sends both real-time sensor data and configuration updates to remote devices. The sensor data is time-sensitive and can tolerate loss, while configuration updates must be delivered reliably and in order. The engineer is considering using a single transport protocol for both types of traffic. Which approach should the engineer take?

Use UDP for configuration updates and TCP for sensor data.

Use TCP for configuration updates and UDP for sensor data.

Use TCP for both, because it provides reliable delivery and ordering for all traffic.

Use UDP for both, because it is low-overhead and fast for all traffic.

What does 'best-effort delivery' mean in the context of UDP?

UDP delivers datagrams only if the network has sufficient bandwidth.

UDP makes an attempt to deliver datagrams but provides no guarantees.

The network prioritizes UDP traffic over TCP traffic.

UDP retransmits any datagram that is lost during transmission.

A VoIP service provider is designing a new softphone application that must minimize latency and jitter during voice calls. The application does not require retransmission of lost packets because real-time voice can tolerate minor packet loss. Which transport protocol should the application use?

TCP, because it uses a three-way handshake to establish a reliable connection before voice transmission.

UDP, because it guarantees packet ordering and delivery, ensuring voice quality.

UDP, because it is connectionless and low-overhead, allowing voice packets to be sent with minimal delay.

TCP, because it provides error recovery and ensures all voice packets are delivered in order.

In TCP, what is the purpose of the three-way handshake?

To synchronize sequence numbers and establish a connection

To authenticate the identities of the communicating hosts

To determine the maximum segment size for the entire session

To encrypt the data exchanged between the two hosts
