Answer:

Whether a traffic light is green, yellow or red

Explanation:

Boolean variables are variables that can either take one out of two options at any given instance.

Analyzing the given options

1. Elevator:

Possible Directions = Up or Down; That's two possible values

But it can only move in one direction at a given instance.

<em>This can be represented using Boolean</em>

2. Traffic Light:

Possible Lights = Green, Yellow or Red

That's three options.

<em>This can be represented using Boolean</em>

<em />

The last two options can be represented using Boolean because they have just two possible values

<em>Hence, option (B) answers the question</em>

sergeinik [125]

Answer:

offline backup solution

Explanation:

In such a scenario, the best option would be an offline backup solution. This is basically a local and offline server that holds all of the flight record data that the cloud platform has. This offline backup server would be updated frequently so that the data is always up to date. These servers would be owned by the aviation company and would be a secondary solution for the company in case that the cloud platform fails or the company cannot connect to the cloud service for whatever reason. Being offline allows the company to access the database regardless of internet connectivity.
