|
a. DNS |
|
|
b. DHT |
|
|
c. DHCP |
|
|
d. DDOS |
Solution:
DHT stands for Distributed Hash Table (DHT)
The P2P connection is created by maintaining a Distributed Hash Table (DHT)
DHT act as the server between the distributed index of the resources on the network.
Hence the correct answer is (b) DHT

please give me clear picture Section 1: DNS nslookup The Domain Name System (DNS) translates hostnames to IP addresses, fulfilling a critical role in the Internet infrastructure. In this lab, we’ll take a closer look at the client side of DNS. Recall that the client’s role in the DNS is relatively simple – a client sends a query to its local DNS server, and receives a response back. Much can go on “under the covers,” invisible to the DNS clients,...
