An administrator makes changes to the default configuration of a router and saves them to NVRAM. After testing, it is discovered that the configurations did not have the desired effect and must be removed. What steps must be taken to remove the changes and return the router to the default configuration? - ✔✔Issue the erase startup-config command, and then reboot the router. A network administrator is tasked with connecting two workgroups that are configured to use different subnets. Which device should be selected to allow connectivity between users on the two networks? - ✔✔Router Which two programs can be used to accomplish terminal emulation for configuring a router from the CLI through the console port?
