A network technician must utilize multimode fiber to uplink a new networking device. Which of the
following Ethernet standards could the technician utilize? (Select TWO).
A.
1000Base-LR
B.
1000Base-SR
C.
1000Base-T
D.
10GBase-LR
E.
10GBase-SR
F.
10GBase-T
Explanation:
B should be 1000Base-SX
Correct 1000BaseSX not SR
Correct me if i am wrong, but an SR type of cables are multimode cables tho. LR/LW, ER/EW are single mode. So B is still valid
There isn’t a 1000Base-SR, however.

LR/LW are single mode, ER/EW either single or multi-mode
