Troubleshooting a Network Issue

Q: Hypethetical:Your local network works but you are not able to connect to Google or any other outside website. You administrator has manually configured your network connection, but it is incomplete ie DHCP was not used. What is missing?Give me your theory--document. Use the problem solving model.

A: Using the Six-Step CompTIA A+ Troubleshooting Theory:

1. Identify the problem: Internet is inaccessible.
2. Establish a theory of probable cause:  DHCP was not used. The network protocol could not configure devices that are connected to the network. 
3. Test the theory to determine the cause: Turning on DHCP should configure the device and assigne an IP address (hypothetical). 
4. Establish a plan of action to resolve the problem and implement the solution: Turn on DHCP so that the devices can be configured and IP address assigned. 
5. Verify full system functionality and, if applicable, implement preventative measures: Verified that DHCP was turned on and that machines on the network could connect to the internet. 
6. Document findings, actions, and outcomes: The work order was logged on my daily work log.
