ping utility的正确叙述?

Q.579的题目是这样的:
which two statements correctly describe the ping utility?(choose two)
A. it uses ICMP
B. it can identify source of an ICMP "time exceeded" message
C. it can identify the path that a packet takes to a remote device
D.it can verify connectivity to a remote device without identifying the path
E. it use UDP

题库上的答案说是AE
可是我觉得正确答案应该是A和D因为ping似乎不是使用udp

不知道各位的想法觉得答案是什么呢?

ADE是錯誤的，ping是只是icmp協定。

ICMP is not UDP
