Question 1

The following description of OLP optical line protection is wrong:

A.When configuring protection, the transceiver of the first port (TO1/RI1) can be configured to work or protection;

B.Switching conditions: MUT_LOS/POWER-DIFF-OVER;

C.APS protocol; no need for the whole network protocol;

D.Protection principle: dual-transmit and selective-receive, single-ended switching, non-recovery by default;

Question 2

During the equipment installation process, the following statement is wrong:

A.When plugging and unplugging a board with a connecting cable or pigtail on the panel, you should first unplug the connecting cable or pigtail before plugging and unplugging

B.Wear anti-static gloves or anti-static wrist straps before touching the equipment, holding boards, veneers, IC chips, etc.

C.Inside the cabinet, the binding interval of optical fiber cable ties/optical fiber ties should not exceed 250mm, and the binding interval of user cable ties should not exceed 200mm

D.In order to dissipate heat, the empty slots on the network element can be used without filler panels

Question 3

Throughput refers to the maximum rate of the network without frame loss. During the test, the test starts from the maximum line rate frame rate Xmax that the device can support. When the device starts to lose frames, reduce the frame rate. When the device does not lose frames Time, increase the frame rate

A.TRUE

B.FALSE

Question 4

In the Ethernet service OAM, the name of the node that can initiate the OAM operation is

A.MEP

B.MA

C.MD

D.MIP

Question 5

If the meter sending data frame rate is X and receiving data frame rate is Y, then the packet loss rate = (XY) /X*100%, usually the packet loss rate + throughput = 1
