Huawei HCIA-Transmission(Huawei Certified ICT Associate-Transmission) Sample Questions:
1. OTM nr.m consists of a maximum of "n" optical multiplexing channels and does not support non-channel-associated overheads. The letter "r" indicates function reduction.
A) FALSE
B) TRUE
2. Which of the following statements about the MST functional module are correct? (Multiple Choice)
A) The MST implements the BIP-8 statistics calculation of the B2 byte.
B) The MST is both the source and sink of the MS.
C) The MST returns bit error information, but not the specific number of bit errors.
D) The MST provides the E2 orderwire channel.
3. An Ethernet private line service is set up between HI (HQ) and H2 (branch) of enterprise H, and five VC-12s are bound in the corresponding VCTRUNK. When one VC-12 fails, the Ethernet private line between HI and H2 is not interrupted.
