Which of the following logic function modules involve processing clock signals? (Multiple choice)
- A . SPI
- B . RST
- C . MCF
- D . SETS
Which of the following statements about latency testing is wrong?
- A . Delay is divided into the delay of the storage and forwarding device and the delay of the forwarding device. Huawei devices are all storage and forwarding devices.
- B . The timing starts from the first bit of the data frame entering and ends when the first bit of the data frame appears at the output terminal P. The time difference between the two is the delay of the bit forwarding device.
- C . The time starts from the first bit of the data frame entering and ends when the first bit of the data frame appears at the output terminal P. The time difference between the two is the delay of the bit forwarding device.
- D . During latency testing, the frame rate can be greater than the throughput
If OSN6800 equipment wants to achieve 1588V2 time synchronization, it must be configured with an electrical layer cross-connect board
- A . True
- B . False
Which of the following steps adds a pointer?
- A . C-12 to VC-12 process
- B . VC-3 to TU-3 process
- C . TUG2 to TUG3 process
- D . TUG3 to VC4 process
When configuring 1+1 optical line protection, you can select RI1/TI2/TO2 as the working channel according to actual conditions.
- A . True
- B . False
To which step does GetEventChannel belong in the working principle of CORBA?
- A . Session maintenance
- B . Session Warning
- C . Information Query
- D . Session initialization
MPLS technology introduces the concept of connection-oriented label switching on the connectionless IP network and integrates IP technology with ATM label switching technology.
- A . True
- B . False
A network has 2250 equivalent network elements of the SDH series, 1000 equivalent network elements of the WDM series, and 1000 equivalent network elements of the router series. The customer purchased value-added functions such as SDH end-to-end, WDM end-to-end, and Corba northbound.
Which of the following is wrong about this network management deployment plan?
- A . Since there are SDH, OTN and router series network elements, it is necessary to install the SDH network element manager, OTN network element manager and router network element manager subsystems
- B . The maximum management capability of the SDH network element manager subsystem is 2500 equivalent network elements: therefore, one SDH network element manager instance is required: the router network has no manager, and the maximum management capability of the system is 500 equivalent network elements, so you need to deploy 1 router Ayuan Manager instance
- C . Since you have purchased SDH end-to-end and WDM end-to-end value-added features, you need to install the SDH network management subsystem and OTN network management subsystem; because you have purchased the Corba northbound interface, you need to install the Corba northbound subsystem.
- D . The OTN series network elements are OSN 6800+OSN 80032 (without ASON, the ratio of the two numbers is 1:1), of which OSN 6800 is the master subrack and OSN8800 is the slave subrack. And each master subrack only carries one slave subrack: the actual number of OSN 8800 physical subracks is 125.
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."
When 61.2M PDH signal is mapped into VC12, the mapping mode used is (). (Byte synchronous mapping/asynchronous mapping/bit synchronous mapping).
