正解:A
While the question as shown appears slightly misformatted, this closely resembles the Windows command:
ping -t 192.168.0.101
Here:
-t means to ping continuously until manually stopped.
In the question: ping -* 6 192.168.0.101, the * is most likely a placeholder or typographical error. Based on CEH format questions and how command-line flags work in ping, -t is the correct flag.
Option A. t - Correct (ping continuously)
Why Others Are Incorrect:
B). s: Not a valid option in Windows ping.
C). a: Used to resolve the hostname from an IP (not related to this).
D). n: Specifies the number of echo requests to send.
