Connection-oriented protocols in the TCP/IP suite are
implemented in the:
A. transport layer.
B. application layer.
C. physical layer.
D. network layer.
Answer / guest
Answer: A
Connection-oriented protocols provide reliability of the
service provided to the higher layer. It is the
responsibility of such protocols in the transport layer to
enhance the quality of service provided by the network
layer. The application layer is concerned with applications
that are closer to the user. Reliable transport of packets
by connection-oriented protocols is transparent to this
layer. The physical layer transmits only raw bits of data.
The network layer routes packets based on information
provided by the transport layer protocol.

An IS auditor discovers that an organization?s business continuity plan provides for an alternate processing site that will accommodate fifty percent of the primary processing capability. Based on this, which of the following actions should the IS auditor take? A.

Identify applications that could be processed at the alternate site and develop manual procedures to backup other processing. C. Ensure that critical applications have been identified and that the alternate site could process all such applications. D. Recommend that the information processing facility arrange for an alternate processing site with the capacity to handle at least seventy-five percent of normal processing.
