== 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 of made-up-on-the-fly test suite for your lab. Let's formalize that 'vm1''' name server for one section each of one the resource records discussed in this lab in a set of test cases.
Pick any section of any lab you like of the labs that would justify having at least three wish to generate 3 separate test cases. Write the test cases in a test plan template, then save a another copy of that for the test plan, making sure to include:your current test runtesting criteria, and execute the tests, recording the resultsfrom 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'''
'''Record steps, commands, and your observations in INVESTIGATION 2 in your OPS335 lab log-book'''
= COMPLETING THE LAB =
To submit the lab - , show that the new '''newly-created DNS records you created are served correctly ''' (via nslookup, host, or dig command), and show your '''completed test plan'''.
