Net+ 4.3 Device Connection Facts
You are implementing a SOHO network for a local business. The ISP has already installed and connected a cable modem in the business. The business has 4 computers that need to communicate with each other and the Internet. The ISP's cable modem has only one RJ45 port. You need to set up the network with the following in mind; Spend as little money as possible, Do not purchase unnecessary equipment, Computers need to have a gigabit connection to the network, New devices should not require management or configuration. You examine each computer and notice only one of the four computers has a wireless NIC; they all have Ethernet NICs. What should you purchase?
An unmanged switch and CAT5e cabling.
You have two switches you need to connect using their uplink ports. The switches do not support auto-MDI Which type of cable should you use?
Crossover cable
You need to transfer data from one laptop to another and would like to use an Ethernet cable. You do not have a hub or a switch. What cable type should you use?
Crossover cable
You want to connect the LAN port on a router to the uplink port on a switch. The switch does not support auto-MDI. What type of able should you use?
Crossover cable
You are setting up two servers, each with computers to the ends, and they are 2km apart. What types of cables should you use for; Drop Cables Patch Cables Uplink Cables WAN Cable
Drop Cables: Cat6 straight-through UTP Patch Cables: Cat6 straight-through UTP Uplink Cables: Cat6 crossover UTP WAN Cable: Single-mode fiber optic
What is the standard typically used in a rollover cable?
RS-232
You have purchased a new router that you need to configure. You need to connect a workstations to the router's console port to complete the configuration tasks. Which type of cable would you most likely use?
Rollover cable
What type to connector is typically found on one end of a rollover cable?
Serial
You need to connect a workstation to a switch using a regular port on the switch (not an uplink port). The switch does not support auto-MDI. What type of cable should you use?
Straight-through
You want to create a rollover cable that has an RJ-45 connector on both ends. How should you connect the wires within the connectors?
pin 1 to pin 8 pin 2 to pin 7 pin 3 to pin 6 pin 4 to pin 5
What is a Crossover cable?
A crossover cable matches the transmit (Tx) wires on one connector with the receive (Rx) wires on the other connector. A crossover cable is used when crossing is not performed automatically, or when crossover is being performed twice. Use a crossover cable when connecting the following devices: Workstation to a workstation, router to a router, or workstation to a router (in a back-to-back configuration) Uplink port on a hub or a switch to an uplink port on a hub or a switch Workstation or a router to the uplink port on a hub or a switch Hub or switch using a regular port to a hub or a switch using the regular port
What is a Rollover cable?
A rollover cable is a cable with an RJ45 connector on one end and an RS232 (serial) connector on the other end. Use a rollover cable to connect the serial port on a workstation to the console connector on a router or switch. Then run a terminal emulation program on the workstation to connect to the console of the router or switch to perform configuration and management tasks.
What is a Straight-through cable?
A straight-through cable connects each wire to the same pin on each connector (pin 1 to pin 1, pin 2 to pin 2, etc.). A straight-through cable is used when the crossover is performed with a hub or a switch. Use a straight-through cable when connecting the following devices: Workstation to a regular port on a hub or switch Router to a regular port on a hub or a switch Regular port on a hub or switch to an uplink port on a hub or a switch
