In-Depth Information
24. You have just finished setting up your DNS infrastructure, and the DNS process seems to be
working well. You want to be able to create a baseline of performance data so that if slow-
downs occur later, you have information for comparison purposes. Which tool should you use?
a. Dnscmd.exe
b. Debug logging
c. Performance Monitor
d. Event logging
25. You're trying to track down a DNS name resolution problem. So far, you haven't been able
to get the data you need to see exactly what's happening when DNS queries fail. You need to
see the actual data packets being sent to and from DNS servers. Which tool should you use?
a.
Dnslint
b.
Debug logging
c.
Performance Monitor
d.
Nslookup
Case Projects
Case Project 9-1: Providing Zone Fault Tolerance
In this project, you work in groups of at least three people. You want to have at least two
other servers that are authoritative for your domain. Work with others in your group so
that the zone for each user's domain is supported by two other servers that are authorita-
tive for the zone. Write down the details of how you will accomplish this task. Have your
instructor review your solution before you implement it. After implementing your solution,
test its effectiveness from your server (without looking at your partner's servers). Write
down what you did to perform your test.
Case Project 9-2: Expanding Your Reach
Now that you can communicate by using DNS lookups with the servers and workstations
in your partner's domains, you want to be able to use DNS to contact resources in the rest
of the domains in your class. You don't want your server to be authoritative for any more
domains. If the NS records of the other domains change, you don't want to have to make
manual changes on your server. Write down the solution you plan to use, submit it to your
instructor for approval, and then implement your solution. Test the solution and write
down how you tested it.
Case Project 9-3: Stress-Testing Your DNS Server
You can work in groups on this project. You have just finished DNS installation and want
to stress-test your DNS server to see how well it handles a lot of queries, both to local zones
as well as zones requiring your server to do recursive lookups. You want to monitor the
server's performance while it's being stressed. Devise a plan to stress-test the server and mon-
itor its performance. Be specific. If feasible, implement your solution after your instructor
has approved it.
