Question 1single_choice
Single-mode fiber, multimode fiber, copper
During a routine operations review, a NOC Engineer analyzes a high error rate on an interface connecting two switches in the 10.16.0.0/17 data center. The switches are 200 meters apart. The engineer issues a diagnostic command on the switch:
Switch# show interfaces status
Port Name Status Vlan Duplex Speed Type
Gi1/0/1 Link-to-Dist connected trunk a-full a-1000 1000BaseSX
Switch# show interfaces GigabitEthernet1/0/1
GigabitEthernet1/0/1 is up, line protocol is up (connected)
...
12400 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
The CRC counter alone does not identify the cause. During inspection of this connected optical link, which candidate installed fiber choice would conflict with the normal multimode-fiber specification of the shown SX optic and require verification?
