Question 124

The base station is deployed, the Tunnel and PW tests are normal, and the base station management is normal, but the base station cannot access the core network normally. What is the reason for the impossibility?

The IP addresses of the PTN equipment interconnection interfaces are not in the same network segment

User packets carry VLAN, but the port attribute is Access

On the L2L3PTN node, the L3VE termination VLAN segment does not include the base station's VLAN segment

There is no route to the address managed by the SGW on L2L3

Question 125

When the switch is working, the device forwards data according to the MAC address forwarding table. Which of the following statements is correct?

If the destination MAC address of the packet is the broadcast MAC address, it will be flooded to all ports including the source port.

If the destination address of the message is a unicast MAC address, look up the MAC address table, and if found, forward the frame to the corresponding port (excluding the source port)

If the destination address of the packet is a unicast MAC address, but there is no corresponding entry in the MAC address table, the packet is discarded

If the MAC address entry of the device reaches the upper specification limit of the device, the device cannot learn new MAC address entries, and the packet is discarded.

Question 126

The characteristic of the open DWDM system is that there are no special requirements for the optical interface of the multiplexing terminal, and only these interfaces are required to comply with the optical interface standard recommended by ITU-T. The DWDM system adopts wavelength conversion technology to convert the optical signal of the multiplexed terminal into a specific wavelength, and the optical signal of different terminal equipment is converted into different wavelengths that comply with ITU-T recommendations, and then multiplexed.

True

False
