Demo Questions
Question 1
According to the IEEE 802JQ standard, where is the VLAN ID field on the Ethernet?
- Before source MAC address and destination MAC address
- Between the source MAC address and the destination MAC address
- After the source MA dog address and the destination MAC address
- not fixed
Correct answer: C
Question 2
What are the reasons for the R-Los alarm reported on the 0TU board?
- The local optical port is not used
- The local laser is turned off, resulting in no optical signal input
- Broken fiber or line performance degradation
- The receiving board at the local end is faulty, and the line receiving fails
Correct answer: ACD
Question 3
Which of the following light source technologies does the 100GOTU board use?
- Direct modulation light source
- Light source of EA modulation method
- MZ modulation light source
- Coherent reception modulation mode light source
Correct answer: D
Question 4
The 802.1Q tag header contains a two-byte TPID. Which of the following is its standard value?
- 8100
- 8847
- 8147
- 88A8
Correct answer: A
Question 5
Both the 1310nm and 1550nm transmission windows are low-loss windows. In the DWDM system, only the 1550nm transmission window is used.
Which of the following options is the main reason?
- EDFA operating wavelength flat region includes this window
- Small nonlinear effects in the 1550nm wavelength region
- 1550nm wavelength region is suitable for long distance transmission
- 1550nm window loss is smaller than 1310nm window
Correct answer: A
Question 6
Which of the following alarms will be reported by the peer end when it is detected that the error code exceeds the limit in the B2 byte?
- MS-AIS
- RS-BBE
- MS-REI
- MS-BBE
Correct answer: C
Question 7
In the CES service, which of the descriptions of "packet loading time" and "jitter buffer time" is wrong?
- The jitter buffer time represents the size of the buffer
- Packet loading time refers to the length of time for PW packets to load TDM frames
- Packet loading time, the configuration of NEs at both ends must be the same
- The value of the packet loading time cannot be less than the jitter buffer time
Correct answer: D
Question 8
DCM optical power debugging requires the input of DCM to be no greater than which of the following values?
- -2
- -3
- -4
- -5
- Translated from Chinese (Simplified) to English - www.onlinedoctranslator.com
Correct answer: B

- Temperature
- Drive Current
- Packaging
- Humidity
Correct answer: ABC
Question 10
The EDFA erbium-doped fiber amplifier is a key component of the new generation of optical fiber systems.
Which of the following options are correct for the description of its advantages?
- High gain
- High output power
- The working wavelength is consistent with the minimum attenuation window of single-mode fiber
- Low noise figure
- Gain Flattening
Correct answer: ABCD
