A technician is working at a client’s office after hours and needs two cables to finish the work but does not have immediate access to prebuilt cables. One cable needed is for a dial-up connection from the dial-up modem to the existing analog POTS jack on the wall. The other cable is for an Ethernet connection from the computer to the existing keystone jack on the wall. The technician has the necessary wire and connectors to make the cables.

After hrs, a technician works at a customer's workplace and requires two wires to meet the deadline but he doesn't have complete access to pre-constructed cables. One wire offered is for a dial-up connection to the current physical jack on the ceiling from those in the dial-up modem.

Another wire is for a computer-based Ethernet connection to the current pipeline socket at the wall. The technician has the cable and connectors required for making the cables.

So, these are the devices the technician requires to connect the wires, and then check that these work properly.
