(single) Regarding the difference between GPON and EPON, which of the following statements is correct?

  1. Both GPON and EPON adopt single-fiber bidirectional data transmission mode, in which EPON uses 1490nm downlink wavelength to transmit data, and GPON uses 1550nm downlink wavelength to transmit data.
  2. GPON protocol standard proposed by IEEE, EPON protocol standard proposed by ITU-T
  3. GPON manages ONUs using the extended OAM protocol
  4. GPON provides higher downstream bandwidth

Answer(s): D



(single) In the H.248 protocol, the terminal can be set to detect events by programming. Once these events are detected, the MG sends a message to the MGC for reporting or the MG takes corresponding action.

  1. Modify
  2. ServiceChange
  3. Notify
  4. AuditCapabilities

Answer(s): C



(single) Regarding EPON, which of the following descriptions is incorrect?

  1. The EPON standard is one of the many TDM-PON standards. It has the basic characteristics of the TDM-PON network: the tree topology network consists of three parts: the OLT, the ONU, and the ODN (Optical Distribution Network).
  2. On the logical topology, the EPON protocol establishes a logical link for the OLT to each ONU. The leading byte of the Ethernet data frame carries the logical link identifier, that is, LLID (Logical Link Identity).
  3. The downstream data stream from the OLT to the ONU is encapsulated into an Ethernet message, and the corresponding LLID is appended and transmitted in the tree PON network. The optical splitter in the ODN broadcasts the data stream to each branch, and all ONUs can receive the downlink Ethernet data frame and selectively receive its own data according to the LLID.
  4. From the ONU to the OLT in the uplink direction, each ONU uses the broadcast mode to share the uplink bandwidth.

Answer(s): D



(Single) For multicast and IPTV, which of the following statements is incorrect?

  1. Multicast refers to the point-to-multipoint communication form in the network.
  2. The core of the multicast technology is to put the message copying work as close as possible to the receiver, and reduce the data traffic on the network.
  3. Through the introduction of controlled multicast, the management and control of multicast users are completed on the DSLAM device.
  4. IPTV is a way of video on demand

Answer(s): D



(single) Which of the following statements is correct?

  1. LAN Switch mainly searches for the corresponding IP address based on the MAC address of the data packet to implement data packet forwarding.
  2. LAN Switch may not recognize the MAC address, but must identify the IP address.
  3. Compared with the shared Hub, a port of the LAN Switch can be said to be a separate collision domain.
    When the D. LAN Switch receives a packet containing an unrecognized MAC address, it forwards the packet directly from the received port.

Answer(s): C
