When LOATOA/THA/TOMTOG and other single board services are activated, the client-side interface of this end reports a SYNC alarm. What is the reason?
- A . The client-side interface on this end receives light abnormally, and the client-side interface on the other end receives light abnormally
- B . The client-side interface on this end receives light normally, but the client-side interface on the other end receives light abnormally
- C . The port receives light normally, and the client-side port receives light normally
- D . The client-side interface on this end receives light abnormally, while the client-side interface on the other end receives light normally
The single-fiber bidirectional optical interface of the PTN equipment distinguishes upstream and downstream business flows based on time slots.
- A . TRUE
- B . FALSE
Which of the following descriptions of the networking requirements for configuring SOM is wrong?
- A . OSC board must be configured in the network
- B . The outbound optical amplifier at the OMS segment must be equipped with an MCA board
- C . An OA board must be configured between the FIU board and the ROADM board or the splitter/combiner board at the receiving end of the OMS segment
- D . Optical amplifier boards of the same dimension can be inserted into different network elements
Regarding the differences between Linux and Solaris operating systems, which of the following statements is wrong?
- A . All disks need to be recognized by the operating system, but Solaris needs to be set in the sd.conf file, while Linux does not need
- B . Solaris itself only supports UFS hard disk file system; in Linux, there are many disk file systems to choose from, the default is ext3
- C . In Solaris, hot-plug devices are managed through cfgadm-. In Linux, when a device is connected, the system automatically recognizes and configures the hot-plug device.
- D . Linux comes with the fssnap command for creating and managing file system snapshots. Solaris does not have such a file system snapshot tool
Which of the following is not included in the performance evaluation of WDM network?
- A . Single-wavelength optical power & flatness
- B . OSNR
- C . Combined optical power
- D . Monitoring signal optical power
- E . Dispersion & FEC BER
In the 40-wavelength system of wavelength division equipment, due to the aging of the customer’s optical cable, the optical cable between sites 2# and 3# needs to be replaced, and a 4# optical amplifier site needs to be added between 2# and 3#. Which of the following statements are correct?
- A . The optical power of site 2# does not need to be re-adjusted
- B . The optical power of site 3# does not need to be re-adjusted
- C . It is necessary to consider whether the dispersion budget is sufficient
- D . No need to consider whether the dispersion budget is sufficient
Which of the following statements is wrong when creating an upgrade task?
- A . The upgrade operator must use the "admin" level user to perform the health check, otherwise some check items will fail and reduce the check efficiency.
- B . For gateway NEs, if you check the "If the NE to be loaded is a gateway NE, force FTP/SFTP protocol to load" configuration item, you need to configure an FTP/SFTP server on the network management server. Improve loading speed
- C . “Force and activate.” In this mode, all groups are activated in parallel, which may cause service interruption.
- D . Check "Use package customization. The software added by the user is a partial package. That is, it is matched according to the single board on the network element. It can improve the efficiency of adding."
Which of the following descriptions of ODUk SNCP protection type is wrong?
- A . When the protection subtype is "SNC/I, there is no need to set the OTN overhead. However, when configuring this type of protection, both ends of the service must be within the range of SM overhead monitoring;
- B . The protection subtype is "SNC/S": monitors the PM layer and needs to set the OTN overhead;
- C . For boards that require ODUk SNCP protection and electrical cross-connection, the configuration varies depending on the selected board and customer-side services;
- D . The ODUk SNCP protection configuration of the receiving site needs to be consistent with the ODUk SNCP protection configuration of the sending site;
Which of the following statements about the position of the dispersion module in the signal flow is wrong?
- A . If there is an OAU board, the DCM is placed between the TDC/RDC of the OAU
- B . If there is only one OBU board, the DCM is placed after the OBU
- C . If there are two OBU boards, the DCM is placed between the two OBUs.
- D . OTM station usually pre-fills 20KM DCM before sending OBU
