Question 1
Which of the following is the data that needs to be collected and saved in the event of a failure? (Multiple Choice)
Question 2
The following description of the signal flow of the OTM site (OSN 8800 device), which is wrong?
Question 3
When the standard Ethernet frame whose length is 64 Bytes is accessed to the Ethernet board, if the QinQ function is enabled, what is the actual frame length of the signal in the board? ( )
Question 4
When you configure the Layer 2 attribute of the Ethernet, you need to set the Default VLAN ID and VLAN Priority of the untagged frame when the TAC ID is set to Access or Hybrid.
Question 5
The NG WDM two-dimensional ROADM site can use the WSMD9 single board, and its signal flow is an optical signal that is connected to the main optical channel from the "IN" optical port. The RDU (ROADM Demix Unit) optical module broadcasts 9 identical optical signals, which are output from the "DM1~DM8" and "ECPO" optical ports respectively. One of the signals is localized by the splitter board, and the other eight signals are dispatched to the other eight directions. Each wave of the main optical channel is connected from the "EXPI" optical port. The multiplexed or single-wave optical signal that needs to be inserted locally is input through the "AM1"~"AM8" optical port.
