The de facto standard Application Program Interface (API) for TCP/IP applications is the “sockets” interface. Although this API was developed for （71） in the early 1960s it has also been implemented on a wide variety of no-Unix systems. TCP/IP （72） Written using the sockets API have in the past enjoyed a high degree of portability and we would like the same （73） with IPv6 applications. But changes are required to the sockets API to support IPv6 and this memo describes these changes. These include a new socket address structure to carry IPv6 （74） ,new address conversion functions, and some new socket options. These extensions are designed to provide access to the basic IPv6 features requited by TCP and UDP applications, including multicasting, while introducing a minimums of change into the system and providing complete （75） for existing IPv4 applications.A.WindowsB.LinuxC.UnixD.DOS

Company.com has a resource group that contains a database that is accessed by a web client based on another system. The communication to the database is TCP/IP. Occasionally after a failure， the end users get unusual error messages that indicate the database server is not available. It has been determined that the web server is trying to access the database server’s information before it has completed file system recovery after a failure. How can HACMP affect this problem？（） A、 HACMP can resequence the order to the starting of the various resource group elements by utilizing Dynamic Node Priority.B、 The order of dependency can be controlled though the HACMP resource group configuration if the web server was made to be part of the HACMP cluster.C、 HACMP can delay making the network label available until after the filesystem checks have completed with the "filesystem mounted before IP is configured".D、 The IP service label can be in a second resource group allowing the sequential processing of resource groups to control when the IP service label is made available.
