When configuring an ADSL connection, which components are necessary for the installation?

1. Ethernet cables and switches

2. Filters or splitters and RJ-11 connectors

3. Modems and routers

4. Cable ties and surge protectors

The correct answer is: Filters or splitters and RJ-11 connectors

When configuring an ADSL (Asymmetric Digital Subscriber Line) connection, having filters or splitters and RJ-11 connectors is crucial for ensuring that the DSL signal works effectively over the existing telephone lines. Filters or splitters are essential because they separate the DSL frequencies from the voice frequencies on a telephone line. This separation allows for simultaneous use of both the internet and traditional phone service, preventing interference that could degrade the quality of the internet connection or phone calls. RJ-11 connectors are necessary as they are the standard connectors used for telephone lines in most residential and commercial settings, enabling the physical connection of the DSL modem to the phone line. Other components, while beneficial for a complete networking setup — such as modems and routers for connectivity and broader wireless access — are not specific to the ADSL setup itself in terms of installation. Ethernet cables and switches relate more to local area networking rather than the initial ADSL connection phase. Finally, cable ties and surge protectors, while helpful for organizing and protecting network infrastructure, are not required specifically for the ADSL connection process.
