Networking II Challenge Submission File
In a Network Far, Far Away!
Make a copy of this document to work in, and then for each mission, add the solution
below the prompt. Save and submit this completed file as your Challenge deliverable.
Mission 1
1.
Mail servers for starwars.com:
asltx.1.google.com
asltx.2.google.com
2.
Explain why the Resistance isn’t receiving any emails:
Both servers lead to a “Non-existent domain”
3.
Suggested DNS corrections:
We need to add the PTR records for the server. nslookup can’t map the IP to
its domain name.
Mission 2
1.
Sender Policy Framework (SPF) of
theforce.net
:
"v=spf1 a mx a:mail.wise-advice.com mx:smtp.secureserver.net
include:aspmx.googlemail.com ip4:45.63.15.159 ip4:45.63.4.215
~all"
2.
Explain why the Force’s emails are going to spam:
Emails are going to spam because the new IP address has not been updated in
the SPF record.
3.
Suggested DNS corrections:
Update the SPF and DNS records to match so that SPF checks pass and allow
emails from the domain to send normally.
Mission 3
1.
Document the CNAME records:
There are no CNAMEs for theforce.net
2.
Explain why the subpage
resistance.theforce.net
isn’t redirecting to
theforce.net
:
resistance.theforce.net is a non-existent domain and has not been added to
the list of CNAMEs for theforce.net
3.
Suggested DNS corrections:
Update the DNS records for theforce.net to include resistance.theforce.net
as a CNAME to redirect traffic to theforce.net.
Sign into the domain host, add the CNAME resistance.theforce.net and update
the DNS records.
Mission 4
1.
Confirm the DNS records for
princessleia.site
:
Server:
2603-8081-49f0-2a60-0000-0000-0000-0001.res6.spectrum.com
Address:
2603:8081:49f0:2a60::1
Non-authoritative answer:
Name:
princessleia.site
Addresses:
15.197.148.33
3.33.130.190
20.40.202.19
2.
Suggested DNS record corrections to prevent the issue from occurring again:
The Resistance should have a completely separate backup server in the event
that the primary server gets attacked, the backup can take over and keep the
website online.
Mission 5
1.
Document the shortest
OSPF
path from Batuu to Jedha:
a.
OSPF
path:
Batuu > D > C > E > F > J > I > L > Q > T > V > Jedha
b.
OSPF
path cost:
23
Mission 6

Wireless key:

2.
Host IP addresses and MAC addresses:
