Which of the following cable types is the most suitable for delivering 10Gb speeds for distances over 328ft (100m) but under 1,312ft (400m)?
The correct answer is A. Multimode fiber. Cat 6a supports 10Gb but only up to 100m (328ft), and Cat 6 supports 10Gb only up to about 55m - both fall short of the 400m requirement. Single-mode fiber can support 10Gb at distances far exceeding 400m (up to tens of kilometers), making it more than capable but also overkill a

Explanation
Cat 6a supports 10Gb but only up to 100m (328ft), and Cat 6 supports 10Gb only up to about 55m - both fall short of the 400m requirement. Single-mode fiber can support 10Gb at distances far exceeding 400m (up to tens of kilometers), making it more than capable but also overkill and more expensive for this range. Multimode fiber (specifically OM3 or OM4) is designed to support 10Gb at distances between 100m and 400m, making it the most cost-appropriate and technically suitable choice for this specific distance range.
