A technician needs to establish a console connection between a new laptop and an older piece of networking hardware, but the interfaces do not match. The networking hardware uses a 9-pin connection for configurations and management. Which type of adapter should the technician select to facilitate the connection using the laptop?
An adapter from the laptop's standard peripheral connection to HDMI
An adapter from the laptop's standard peripheral connection to RS-232 serial port
An adapter from the laptop's standard peripheral connection to Ethernet port
The correct answer is 'An adapter from the laptop's standard peripheral connection to RS-232 serial port'. The DB9 9-pin serial connector was commonly implemented for RS-232 serial ports on older equipment for direct management access. Given that modern laptops typically do not have RS-232 serial ports, an adapter is necessary. Options suggesting an Ethernet or storage interface (e.g., 'An adapter from the laptop's standard peripheral connection to Ethernet port') or an A/V output interface (e.g., 'An adapter from the laptop's standard peripheral connection to HDMI') are incorrect because Ethernet is for networking, HDMI is for audiovisual, and none are used for 9-pin serial communications.
