Can you show me from zero how to solve this question?

I do not undestand anything

Use ONLY the Domain Names and IPs in the following table to answer the questions. You may always use TTL to represent the value to be included in a RR (Resource Record).

Domain Name IP

root DNS server root.dns.net A1.B1.C1.D1

TLD DNS server for the .edu domain tldX.dns.edu A2.B2.C2.D2

TLD DNS server for the .com domain tldA.dns.com A3.B3.C3.D3

Authoritative DNS server in the .lamar.edu domain primary.dns.lamar.edu A4.B4.C4.D4

Authoritative DNS server in the .google.com domain primary.dns.google.com A5.B5.C5.D5

Local DNS server in the .lamar.edu domain localPri.dns.lamar.edu A6.B6.C6.D6

Local DNS server in the .google.com domain localPri.dns.google.com A7.B7.C7.D7

Web server in the .lamar.edu domain www.lamar.edu A8.B8.C8.D8

Web server in the .google.com domain www.google.com A9.B9.C9.D9

(a) Write all the RRs (Resource Records) possibly stored in the DNS database on the root DNS server.

(b) Write all the RRs possibly stored in the DNS database on the TLD DNS server for the .edu domain

(d) Write all the RRs possibly cached in the DNS database on the local DNS server for the .lamar.edu domain assuming that it does NOT cache any TLD or authoritative DNS servers information. (hint: the information on the root DNS server is in the system configuration instead of in the cache).
