You’ve got a laptop that’s been assigned a DHCP address and no other privileges. Explain the steps you would take to discover network topology from there.

1- Go to controlpanel

2- Then click on network and sharing center

3- Then click on seefull Map

Its show map of network toplogy

have a look at the IP laptop receives, you will get the gateway.

From there do a IP scan or use the network map feature in windows.

What can you tell me about your working knowledge of Multicast Protocols?

In DHCP we have a step\concept called DORA

DHCP (D)iscover - Client "LAPTOP" Discover the DHCP Server

DHCP (O)ffer  - The DHCP server now Offer a set of IP's to the LAPTOP

DHCP (R)equest - Now the LAPTOP will Request the said IP to the DHCP server 

DHCP (A)ck - After that, the DHCP server will now Acknowledge the request of the laptop to get that specific ip address.

Please reply for any comment about my answer. Thank you Sir Fuadul.
