Free Juniper JN0-105 Actual Exam Questions - Question 2 Discussion

C/D? UDP is known for being connectionless, so D fits well. It also doesn’t do handshakes or retransmissions, which means it’s best effort — no guarantees packets arrive or in order, so C works too. A and B are pretty clearly wrong since UDP isn’t more reliable or slower than TCP, it usually has less overhead and can be faster.

It’s definitely D and C. UDP skips the handshake and just sends packets out, so it’s connectionless, and there’s no guarantee they arrive, which matches best effort. A and B are clearly off.

D imo, because UDP doesn’t set up connections, plus C since it doesn’t guarantee delivery.

It’s C and D for sure. UDP doesn’t establish a connection before sending data, which matches “connectionless” in D. Also, it doesn’t guarantee delivery or order, so it’s considered “best effort,” which is C. A and B are off since UDP isn’t more reliable or slower than TCP—it’s actually faster but less reliable.

Options C and D seem correct, UDP is connectionless and best effort.
