== LAB OBJECTIVES DOMAIN NAME SYSTEM RESOURCES== Online References: *[https://en.wikipedia.org/wiki/Test_case Test Case Definition] (Wikipedia definition of a Test Case)  ==OBJECTIVE ==
Last week you were introduced to administering a simple authoritative DNS server. This week we will review that topic, but focus on learning a few more resource record types. This lab will also provide the background and tools (such as a test case) that will be used in your assignment #1.
:To Demonstrate the point in the statement above:
:Find the MX record for senecacollege.ca using the '''dig''' command:<br><source lang="bash">dig senecacollege.ca MX</source>:Notice that the email servers aren't even a subdomain of senecacollege.ca but a completely different company (Microsoft in this case).<br>In other cases (for example , check the records for ''google.com'') the email servers are within the company's domain.
In rare cases, there may be no MX records associated with a domain (For example: try '''dig littlesvr.ca'''). In this latter case, the server called littlesvr.ca, which is supporting a web-server, is also supporting the email server for the same IPADDR.
A '''TXT''' record is used to store any type of data or information. It is generally considered to be a "user-defined" section in order to provide additional information that the DNS system was not designed to handle or accommodate. For example, a common use of the TXT record is to support '''SPF''': which is a special type of record used to help receiving email servers determine the likelihood that a message is spam.
=== Update Additional Resource Records for Your Domain for VM1 Name Server ===
Configure your '''VM1''' machine (Bind server) to incorporate each of the records discussed above and verify that your records work by DNS query.
'''Record steps, commands, and your observations in INVESTIGATION 1 in your OPS335 lab log-book'''
=== Create Test Cases for Your VM1 Machine ===
When I check Provide query results for your lab - I normally ask you to run some commands, and I'll ask you some questions, and that is a sort ''vm1''' name server for each of made-up-on-the-fly test suite for your resource records discussed in this lab. Let's formalize that for one  Pick any section of one lab any of the labs that wish to generate 3 separate test cases. Write the test cases in a set test plan template, then save another copy of the test casesplan, making sure to include:your current testing criteria, and the results from you running that current testing criteria. You will be required to show this test plan upon sign-off of this lab'''Record steps, commands, and your observations in INVESTIGATION 2 in your OPS335 lab log-book'''  = COMPLETING THE LAB =
Pick any section of any To submit the lab you like that would justify having at least three test cases. Write , show the test cases in a template'''newly-created DNS records''' (via nslookup, host, save a copy of that for the current test runor dig command), and execute the tests, recording the resultsshow your '''completed test plan'''.
