Refer to the exhibit. Site A was recently connected to site B over a new single-mode fiber path. Users at site A report intermittent connectivity issues with applications hosted at site B. What is the reason for the problem?
A.
Physical network errors are being transmitted between the two sites.
B.
Heavy usage is causing high latency.
C.
The wrong cable type was used to make the connection.
D.
An incorrect type of transceiver has been inserted into a device on the link
D is correct. The -SR stands for a short reach transceiver and is used for short range applications up to 300 meters, while the -LR can achieve up to 10km
SR is 400m (from my source anyway, other sources here have a different range), while LR is 10 km. Anyway, they are 7 km apart.
