| A. | 100 |
| B. | 250 |

| D. | 1000 |
Answer : B Explanation : A crossbar switch connects n inputs to m outputs in a grid, using electronic micro switches at each cross point, totally n x m cross points are required for crossbar switch. In general 25 percent of the cross points are used at a given time. The rest are idle so, totally 1000 cross points, so 25% = 250 crosspoint points are in use. |
