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 .msudenver.edu domain | primary.dns.msudenver.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 .msudenver.edu domain | localPri.dns.msudenver.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 .msudenver.edu domain | www.msudenver.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
Write all the RRs possibly stored in the DNS database on the authoritative DNS server for the .msudenver.edu domain
Write all the RRs possibly cached on the local DNS server for the .msudenver.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).
