問題 #1

Which of the following description of the principle of automatic protection switching of the standard SSM protocol is correct? (Multiple Choice)

A. The network element broadcasts the clock quality information and the clock source ID of the synchronization source to the downlink site through the S1 byte, and reverse notices the uplink site that the clock quality from the local network element is "not available for synchronization" by the S1 byte in the direction of the synchronization source.
B. The network element broadcasts the clock quality information of the synchronization source to the downlink site through the s1 byte. And reverse notice the uplink site by the S1 byte in the direction of the synchronization source that the clock quality from the local network element is "not available for synchronization".
C. According to the clock source priority table, the network element first selects the clock with the highest quality level from the available clock sources as the synchronization source.
D. If there are multiple clock sources with the highest quality level, the network element selects the clock with the highest clock priority as the synchronization source.

問題 #2

The following limitations of alarm and performance analysis methods are: (Multiple Choice)

A. Field maintenance personnel cannot understand the current health of the equipment.
B. In the case of complex networking, service, and fault information, many alarms and performance events may occur along with the occurrence of faults. Due to too many reports and performance events, maintenance personnel are unable to analyze.
C. The network administrator cannot obtain any alarms, time, and historical alarms of the device.
D. When some faults occur, there may be no obvious alarms or performance events reported, and sometimes no alarms or performance events are found.

問題 #3

Which of the following description of the principle of automatic protection switching of the standard SSM protocol are correct? (Multiple choice)

A. According to the clock source priority table, the network element first selects the clock with the highest quality level from the available clock sources as the homologous source.
B. The network element broadcasts the clock quality information and the clock source ID of the synchronization source through the downstream station between the S1 bytes, and notifies the upstream station that the clock quality from the local network element is "not available for synchronization" by the S1 byte in the direction of the synchronization source.
C. The network element broadcasts the clock quality information of the synchronization source to the downstream site through the S1 byte, and notifies the upstream station that the clock quality from the local network element is "not available for synchronization" by the S1 byte in the direction of the synchronization source.
D. If there are multiple clock sources with the highest quality level, the network element selects the clock with the highest clock priority as the synchronization source.

問題 #4

Which of the following description of the extended ECC is correct? (Multiple Choice)

A. In the automatic extended ECC mode, you need to connect the Ethernet ports of the two NEs with a direct-connected network cable (or a standard network cable through B), extend the ECC, and specify the server and client.
B. The scale of the extended ECC network (the sum of the server and the client) must not exceed 8.
C. Extended ECC is divided into automatic extended ECC and manual extended ECC. One network element can only support one mode at the same time. These two methods cannot be directly docked.
D. Extended ECC recommends to use manual basis, which reduces mutual negotiation between network elements.

問題 #5

TEM28 is the Ethernet convergence tributary board. Which of the following descriptions about the TEM28 board are correct? (Multiple Choice)

A. The TEM28 board supports the L2 switch module and needs to configure the port to VCTRUNK service.
B. The electrical signal can be output ODU0, ODU1flex, 00U1 or ODU2 signals to the backplane for cross scheduling through operations such as encapsulation mapping and OTN framing.
C. TEM28 can simultaneously access FE, GE, 10GE LAN and 10GE WAN services through different ports.
D. RX1/TX1~RX4/TX4 ports are 10GE optical ports, which can handle 10GE LAN/10GE WAN services. Other interfaces are GE optical ports, GE electrical interfaces or FE electrical ports which can handle GE or FE services.
