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.

== 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.
=== Create Test Cases for Your VM1 Machine ===
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'''
= 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'''.
