Which command is used to query DNS?
Nslookup (stands for “Name Server Lookup”) is a useful command for getting information from the DNS server.

What is nslookup command in CMD?

Which is the type of DNS scope Mcq?
The correct answer is “option 3”. CONCEPT: DNS, which stands for Domain Name System, maps domain name into Internet Protocol (IP) address. Hence, the DNS maps the IP addresses to a hierarchy of domain names.
Which two commands would be used to check if DNS?
Explanation: The ping command tests the connection between two hosts. When ping uses a host domain name to test the connection, the resolver on the PC will first perform the name resolution to query the DNS server for the IP address of the host.

The nslookup command queries internet domain name servers in two modes. Interactive mode allows you to query name servers for information about various hosts and domains, or to print a list of the hosts in a domain.
What is DNS recursive query?
What is recursive DNS? A recursive DNS lookup is where one DNS server communicates with several other DNS servers to hunt down an IP address and return it to the client. This is in contrast to an iterative DNS query, where the client communicates directly with each DNS server involved in the lookup.

What type of query is nslookup?
In simple terms, Nslookup queries a local or the remote DNS servers to dig out information about the requested domain. You can also use many variants of this command on CMD to find out more and learn more such as knowing about the mail servers, FQDN, IP address etc.
