GAQM Exam CPEH-001 Topic 7 Question 64 Discussion

Actual exam question for GAQM's CPEH-001 exam

Question #: 64
Topic #: 7

One of the ways to map a targeted network for live hosts is by sending an ICMP ECHO request to the broadcast or the network address. The request would be broadcasted to all hosts on the targeted network. The live hosts will send an ICMP ECHO Reply to the attacker's source IP address. You send a ping request to the broadcast address 192.168.5.255.

There are 40 computers up and running on the target network. Only 13 hosts send a reply while others do not. Why?

AWindows machines will not generate an answer (ICMP ECHO Reply) to an ICMP ECHO request aimed at the broadcast address or at the network address.

BLinux machines will not generate an answer (ICMP ECHO Reply) to an ICMP ECHO request aimed at the broadcast address or at the network address.

CYou should send a ping request with this command ping ? 192.168.5.0-255

DYou cannot ping a broadcast address. The above scenario is wrong.

The Windows machines not replying to the broadcast ping makes sense, it's a security feature to prevent potential attacks.
