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?

I thought all hosts would reply, this is interesting.

Wait, are you sure Linux doesn't respond to broadcasts?

Option D seems off to me; I feel like you can ping a broadcast address, but not all devices will respond.

I thought you could ping a broadcast address, but maybe it depends on the configuration of the devices on the network.

I'm not entirely sure, but I think Linux machines can respond to broadcast pings. I feel like I saw a question like this in practice.

I remember reading that Windows machines often block ICMP replies to broadcast addresses, so option A might be correct.

I'm a little confused by this one. I know it's related to load balancing, but I'm not sure which attribute controls the time interval for switching indexers. I'll have to review my notes and see if I can figure this out.

Okay, I think I've got this. The first blank is asking about contracts for specialized services provided by professionals, while the second blank is about indefinite delivery contracts for transportation. I'll select the option that matches those descriptions.

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.
