    BGP runs over a reliable transport （ ）. This eliminates the need to implement explicit update fragmentation, retransmission, acknowledgement, and （请作答此空）. Any authentication scheme used by the transport protocol may be used in addition to BGP's own （ ）mechanisms. The error notification mechanism used in BGP （ ）that the transport protocol supports a “graceful” close, i.e., that all outstanding data will be delivered （ ）the connection is closed.

    A.synchronization
    B.conflict
    C.transport
    D.sequencing

    答案：D
    解析：
    bgp通过可靠的传输协议运行。这样就不需要实现显式的更新分段、重新传输，确认和排序。使用的任何身份验证方案除了bgp自己的身份验证机制之外，还可以使用传输协议的验证方案。bgp中采用的错误通知机制，假定传输协议支持“正常”关闭，也就是说，所有未完成的数据将在连接关闭之前交付。

    BGP协议基于TCP协议，端口（ ）。BGP协议中，路由器通过（请作答此空）报文报告检测的错误信息。

    A.Update
    B.Keepalive
    C.Open
    D.NOTIFICATION

    答案：D
    解析：
    BGP常见四种报文，分别是OPEN报文、KEEPLIVE报文、UPDATE报文、NOTIFICATION报文。OPEN报文：建立邻居关系；KEEPALIVE报文：保持活动状态，周期性确认邻居关系，对OPEN报文回应；UPDATE报文：发送新的路由信息；NOTIFICATION报文：报告检测到的错误。

    All three types of cryptography schemes have unique function mapping to specific.For example,the synunetric key（71）approach is typically used for theencryption of data providmg（72）,whereas asymmetric key cryptography is maidy used in key（73）and noruepudiation,thereby providing confidentiality and authentication.The hash（74）（noncryptic）,on the other hand,does not provide confidentiality but provides messageintegrity,and cryptographic hash algorithms provide message（75）and identity of peers during transport over insecure channels.
