Huawei HCS - Transmission Sample Questions:

1. When the scheduling granularity of the N302 board is ODUflex, what are the supported protection types?

A) Tributary SNCP Protection
B) Client side 1+1 protection
C) In-board 1+1 protection
D) ODUk SNCP Protection

2. Which of the following is the destination MAC address of the Layer 2 header of the data received by the PTN960 from the LTE base station?

A) The network port MAC of the PTN device connected to the base station
B) User-side port MAC of the PTN device connected to the base station
C) MAC of the base station gateway L3VE on the L2/L3 node
D) The port MAC of the EPC device connected to the core L3PTN

3. Which of the following statements about 100G coherent PDM-QPSK modulation is incorrect?

A) PDC-QPSK supports DCMfree and DCM system applications, and supports smooth upgrade from existing 10G/40G network to 100G system.
B) PDM polarization multiplexing technology is adopted, which has better nonlinear tolerance than
40GePDM-BPSK.
C) The essence of QPSK modulation is to reduce the baud rate of the optical signal by half without reducing the line rate by selecting 4 possible values in the phase of the optical field.
D) PDM-QPSK technology is the main modulation code technology for 100G transmission, which can reduce the line rate of 112Gb/s to the baud rate of 28Gbaud/s, greatly reducing the loan requirements for (optical) electrical devices.

4. Regarding the operation of deleting the path from the network management, which of the following statements is wrong?

A) After the path is deleted from the network layer and the network element, the service will be interrupted
B) Delete the path from the NE layer. Delete the path on the NE side and the NE layer together.
C) Once the network layer deletes the trail, the service will not be interrupted
D) Deleting a trail from the network layer only deletes the WDM trail at the network layer on the NMS side

5. IP As the core protocol of the network layer in the TCP/IP protocol stack, the fixed part of the packet header has 20 bytes and carries a variety of identification fields to define the transmission of the data packet.
Which of the following statements about the identification field is incorrect?

A) version (4bit), identifies the IP version, the current iP version is 4, and the next generation version is 6
B) TLN Time to live, 8bit), when an IP packet is generated, an initial value will be set, and when an old packet is forwarded from one router to another, the TTL value will decrease by 1. When the TTL is 0, the packet will be discarded
C) Total Length (16bit), indicating the length of the IP header
D) Protocol (8bit), indicating the protocol type to which the IP payload belongs, and a value of 6 indicates that the IP encapsulation is a TCP segment
