After a network outage, a PC technician is unable to ping various network devices. The network administrator
verifies that those devices are working properly and can be accessed securely.
Which of the following is the MOST likely reason the PC technician is unable to ping those devices?
ICMP is being blocked
SSH is not enabled

ICMP is a protocol that is commonly used by tools such as ping, traceroute, and pathping. ICMP offers no
information If ICMP request queries go unanswered, or ICMP replies are lost or blocked.
