問題 #1

In the network management planning, which of the following descriptions is correct (multiple choice)

A. In the deployment planning of the network management subsystem, it is necessary to determine the network element manager subsystem to be installed according to the network element series. For example, if you need to use the Corba northbound interface, you need to install the Corba northbound subsystem.
B. Among other requirements, if the client is running on the server side at the same time, the management ability will be reduced by 60%, so it is recommended that the client and server be run separately.
C. Equivalence factor = resources occupied by physical network elements or ports / system resources occupied by equivalent network elements; virtual network elements do not calculate management capabilities; pre-configured network elements are equivalent to virtual network elements.
D. Centralized deployment scheme is recommended for network management deployment planning. Only consider the use of a distributed deployment solution when the customer strongly requires it.

問題 #2

Regarding system security planning and reliability planning, which of the following is correct (multiple choice)

A. Operational safety and reliability design includes: access control, ACL control, time control, limit on the number of logins, user monitoring and operation confirmation.
B. The security management of the network management mainly includes object management, password management, access control management, and power and domain management.
C. In the process of data output, to ensure the security of data transmission, U2000 needs to support data encryption protocol, in which SSLv3 protocol can be used for data transmission encryption between U2000 and network element equipment, and it can also be used for U2000 and upper OSS system Data transmission between is encrypted.
D. Based on security considerations, the recommended communication bandwidth for medium-scale remote dual-system hot backup communication is 2M.

問題 #3

Network elements A, B, and C are OSN 3500 forming a chain network. The two stations A and C are connected to routers. The IP routers are connected to the OptiX SDH equipment through the POS port of STM-1. The PAS port connects J1 and C2 bytes. It is also used as a payload to transfer bytes (used to carry services). The network element A to the network element C creates a VC4 service, and the network element B uses VC4 to pass through.
In this case, is there an alarm report inside the SDH network?

A. There is a C2 mismatch alarm
B. No warning
C. There is a J1 mismatch alarm
D. There is a C2 not loaded alarm

問題 #4

Which of the following is the error about the optical power commissioning?

A. The actual gain upper threshold of an OAU is smaller than the nominal gain upper threshold, indicating that the performance of the OAU board is degraded and it is recommended to replace it.
B. For 10G and 2.5G systems, adjust the received optical power of the wavelength conversion board to "high 3 low 5", which is 3dB higher than the receiving sensitivity and 5dB lower than the overload point.
C. Adjust the OAU gain of the optical amplifier board to make the output optical power reach the standard.
D. Adjust the VOA (adjustable optical attenuation) in front of the optical amplifier board so that the input optical power of the board = the input single-wave nominal optical power + 10lgN, where N is the actual wave number. If it is not adjusted to the nominal value, adjust the VOA attenuation to the minimum.

問題 #5

If the low-level crossover of SDH equipment is exhausted, there are several common optimization schemes (multiple choice)

A. Replace the high-capacity cross board
B. Routing time slot optimization
C. Change channel protection to multiplex section protection
D. Replace the circuit board
E. Upgrade host software
