The technology that many businesses use to monitor key performance indicators is B. Dashboards.

Here's why:

A. Firewalls: These are security systems for networks. They monitor and control incoming and outgoing network traffic based on predetermined security rules, but they do not monitor performance indicators.

B. Dashboards: These are management tools that track and analyze KPIs, metrics, and other key data points relevant to a business, department, or specific process. They provide a central location for businesses to monitor and analyze performance in real time, so they are used to monitor key performance indicators.

C. Extranets: These are controlled private networks that allow access to partners, vendors and suppliers, or an authorized set of customers. They are not typically used to monitor KPIs.

D. Terabytes: This is a unit of information or computer storage equal to one trillion bytes. It's not a technology used to monitor KPIs.
