Huawei Certified Internetwork Expert-Transmission Sample Questions:

1. Reasons why it is impossible to frequently disconnect OTN equipment network elements

A) The electrical monitoring is used, and the line quality is not good
B) The same NE user logs in to the NE at the same time
C) Use optical monitoring, DCC mode setting is wrong
D) Network element ID conflict

2. Which of the following statements about the configuration, testing and maintenance of IPA functions are correct? ()

A) The purpose of testing the IPA function is to verify that if any fiber is broken in the fiber path included in the IPA, the amplifier included in the IPA can be turned off. After the fiber is restored, the amplifier can be automatically turned on, and The power change is within 0.5dB.
B) After the IPA function is successfully activated, when the amplifier board detects LOS, the optical power of its output port becomes safe optical power
C) Select "Configuration/IPA Management" in the function tree of the NE Manager to configure the IPA start delay value
D) When the fiber interruption is repaired and the IPA cannot be terminated, it may be because the IPA protection group is not configured with the "detection board", only the auxiliary detection board is configured, and the auxiliary detection board reports an alarm that triggers IPA
E) IPA function is only applicable to Raman amplifiers, not to ordinary amplifiers

3. Which of the following IP addresses is a class C IP address

A) 127.0.0.1
B) 10011010.01101110.10000000.01101111
C) 10.110.192.111
D) C2.A8.D2.e1

4. When planning AM, you need to consider the priority planning of E1. Which of the following options are the planning principles of E1 priority (multiple choice)

A) The E1 priority function is mainly used in the scenario of Hybrid microwave transmission IMA service. At this time, the guaranteed E1 capacity should be equal to the E1 capacity required by IMA to transmit high-priority services; the full-capacity E1 capacity should be equal to the E1 capacity used by IMA.
B) The priority of the E1 service has nothing to do with the time slot number of the IF board it occupies, but the priority is specified when the cross-connection of the E1 service is configured. There are two types of E1 priority: high and low.
C) When the E1 priority function is enabled, E1 service bandwidth under full capacity ≤ full capacity service bandwidth-guaranteed capacity service bandwidth + E1 service bandwidth under guaranteed capacity.
D) The priority set when an E1 service passes through a multi-hop microwave link can be different.

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