In this assignment, you will use the '''335assignvirtual network''' virtual network and the '''seedling''' cloning-source that you created in assignment 1 (part 1) to create two name-servers. One of the cloned VMs (hostname: '''elmbalsam''') will be a master name server, and the other VM (hostname: '''birchspruce''') will be a slave name server. You will install and setup the master and slave servers in order to provide various domain name resolutions for existing servers, and for servers that will be created and used in assignment #2. 

'''Weight''': 57% of the overall grade

=== Clone "ns1" VM Set-up Master Name Server ('''balsam''')=== Perform the following steps for this section: #Create a clone virtual machine called '''balsam''' from the '''seedling''' cloning-source. Refer to the table below for '''address''' and '''hostname'''.#Create a '''regular user''' for this virtual machine using '''your Seneca userID'''.#Setup a DNS server on your '''balsam''' virtual machine with noting the following items below:<ol type="Cloning Sourcea" &amp; Perform Setup Tasks><li>This virtual machine will be the '''Master DNS server'''.</li><li>This machine will provide '''forward''' and '''reverse''' lookups of ALL virtual machines in the '''coniferous.trees.ops''' zone, including resource records for virtual machines that do not currently exist.</li><li> Make certain to include an '''MX record''' for your admin e-mail contact: '''yoursenecaid@coniferous.trees.ops'''</li><li>This machine will allow other machines (outside the '''coniferous.trees.ops.''' zone) to perform DNS lookups among ALL virtual machines within the '''coniferous.trees.ops''' network.</li><li>Any machine in the '''coniferous.trees.ops''' network may use this machine to perform queries of machines outside the network, however it will route all such queries through the DNS server you created in lab #3.</li></ol> === Set-up Slave Name Server ('''spruce''') ===
