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.

Show Suggested Answer

Suggested Answer: C

The order should be Passive information gathering, Network level discovery, Host scanning and Analysis of host scanning.

Why can't I ping the broadcast address? I thought that was a classic network mapping technique. This exam is really testing my fundamentals!

Yikes, looks like I shouldn't have been counting on that broadcast ping to map the network. Guess I'll have to try a different approach.

Haha, pinging the entire range from 192.168.5.0 to 192.168.5.255? That's like using a sledgehammer to crack a nut!

I thought Linux machines were more open to these kinds of requests, interesting that they don't respond either.

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

Hmm, that makes sense too. Maybe we should review the question again.
