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. 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.
C. Based on security considerations, the recommended communication bandwidth for medium-scale remote dual-system hot backup communication is 2M.
D. The security management of the network management mainly includes object management, password management, access control management, and power and domain management.
正解：A,B,D

正解：C
質問 6：
The interface board N1SF64 of OSN 7500 and the A1SF64 of OptiX 10G (Metro 5000) support different protocols, so they cannot be connected.
A. TRUE
B. FALSE
正解：A
質問 7：
Which of the following statements about the ALC function and configuration principles of the OTN system is correct? () (multiple choice)
A. It is recommended that the number of network elements in the ALC link is less than 20, otherwise the ALC adjustment may time out and cause failure
B. Each ALC link has a unique ID, and ALC nodes can belong to different DCN subnets
C. The ALC function can automatically adjust the output optical power of the amplifier in which the line attenuation changes. Except for the first site, other sites must be equipped with power detection units
D. The detection and reference unit of the first node cannot use the same optical port of the same board
E. The "working mode" of the OA board and RAU1/RAU2 board must be configured as "gain lock", if it is configured in other modes and ALC is configured, the ALC will not be adjusted
F. If there are two cascaded OA boards in the node, the first node only configures the second OA board as the reference unit, and do not deploy the power detection unit
