My opinion is the answers A and D. I would choose A if you can only choose one, though.
Answer:
We can periodically take a snapshot of the Domain Name System (DNS) caches in the local Domain Name System (DNS) servers.
Explanation:
We can periodically take a snapshot of the Domain Name System (DNS) caches in the local Domain Name System (DNS) servers. The Web server that appears most frequently in the Domain Name System (DNS) caches is the most popular server. This is because if more users are interested in a Web server, then Domain Name System (DNS) requests for that server are more frequently sent by users. Thus, that Web server will appear in the Domain Name System (DNS) caches more frequently.
Answer:
Initially if x = a = 2437 and y = 875, condition (1) that is x>y is true and output would be x = 1562 with y = 87
Explanation:
According to pseudo code the code will run until x becomes equal to y. Initially if x = a = 2437 and y = 875, condition (1) that is x>y is true. So next step would be x=x-y and output would be x = 1562 with y = 875. With initial values x = a = 2437 and y = 875, x becomes equal to y after 21 iterations and output is x=y=1

A tool which might be used by an attacker during the reconnaissance phase of an attack to glean information about domain registrations is: Whois.
<h3>What is a DNS server?</h3>
A DNS server can be defined as a type of server that is designed and developed to translate domain names into IP addresses, so as to allow end users access websites and other internet resources through a web browser.
This ultimately implies that, a DNS server refers to a type of server that translate requests for domain names into IP addresses.
In this context, we can infer and logically deduce that Whois is a tool which might be used by an attacker during the reconnaissance phase of an attack to glean information about domain registrations.
