The MA5800 supports upstream transmission through the control board or upstream board, and supports 10...

Upstream Transmission Overview :

The MA5800 is a next-generation OLT platform that supports multiple upstream transmission options, including 10 GE (Gigabit Ethernet) and GE (Gigabit Ethernet).

Default Configuration :

By default, the upstream ports on the MA5800 are configured for 10 GE transmission. However, administrators can adjust the speed using the speed command to match the requirements of the interconnected device.

Matching Port Rates :

For successful communication, the upstream port rate on the MA5800 must match the rate of the port on the upper-layer device (e.g., switch or router). Mismatched rates can lead to communication failures.

Why TRUE?

The statement accurately describes the default configuration and the importance of matching port rates to ensure proper communication.

Thus, the correct answer is A .
