HPE Aruba Certified Central Associate (ACCA) — Question 27

You are planning a 40Gbps link between two sites 35km apart.
What type of cable will be required?

Answer options

• A. ZTP
• B. Single-mode fiber
• C. UTP
• D. Multi-mode fiber

Correct answer: B

Explanation

The correct answer is B, Single-mode fiber, as it is designed for long-distance communication and can support high bandwidths like 40Gbps over distances greater than 35km. Options A (ZTP) and C (UTP) are not suitable for this purpose, as ZTP is a protocol and UTP cannot handle such high speeds over long distances. Multi-mode fiber (D) is typically used for shorter distances and would not be ideal for a 40Gbps link over 35km.
