Demo Questions

Question 1
According to the IEEE 802JQ standard, where is the VLAN ID field on the Ethernet?
  1. Before source MAC address and destination MAC address
  2. Between the source MAC address and the destination MAC address
  3. After the source MA dog address and the destination MAC address
  4. not fixed
Correct answer: C
Question 2
What are the reasons for the R-Los alarm reported on the 0TU board?
  1. The local optical port is not used
  2. The local laser is turned off, resulting in no optical signal input
  3. Broken fiber or line performance degradation
  4. 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?
  1. Direct modulation light source
  2. Light source of EA modulation method
  3. MZ modulation light source
  4. 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?
  1. 8100
  2. 8847
  3. 8147
  4. 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?
  1. EDFA operating wavelength flat region includes this window
  2. Small nonlinear effects in the 1550nm wavelength region
  3. 1550nm wavelength region is suitable for long distance transmission
  4. 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?
  1. MS-AIS
  2. RS-BBE
  3. MS-REI
  4. 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?
  1. The jitter buffer time represents the size of the buffer
  2. Packet loading time refers to the length of time for PW packets to load TDM frames
  3. Packet loading time, the configuration of NEs at both ends must be the same
  4. 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?
  1. -2
  2. -3
  3. -4
  4. -5
  5. Translated from Chinese (Simplified) to English - www.onlinedoctranslator.com
Correct answer: B
Question 9
The DWDM system has extremely high requirements on the stability of the light source. Which of the following factors will affect the stability of the light source?
  1. Temperature
  2. Drive Current
  3. Packaging
  4. Humidity
Correct answer: ABC
Question 10

Which of the following options are correct for the description of its advantages?
  1. High gain
  2. High output power
  3. The working wavelength is consistent with the minimum attenuation window of single-mode fiber
  4. Low noise figure
  5. Gain Flattening 
Correct answer: ABCD
