Which two options best describe the purpose of session ID and cookie field in a L2TPv3 packet？（）A、The session ID is a 32-bit locally significant field used to identify the call on the destination or egresstunnel endport. The session ID will be negotiated by the control connection or statically defined if usingthe L2TP v3 data plane onlyB、The cookie is a variable length（with a maximum of eight bytes），word-aligned optional field. The controlconnection can negotiate this as an additional level of guarantee beyond the regular session ID lookupto make sure that a data message has been directed to the correct session or that any recently reusedsession ID will not be misdirectedC、The cookie is a 32-bit locally significant field used to identify the call on the destination or egress tunnelendpoint. The cookie will be negotiated by the control connection or statically defined if using theL2TPv3 data plane onlyD、The session ID is a variable length（with a maximum of eight bytes），word-aligned optional field the control connection can negotiate this as an additional level of guarantee beyond the regular cookielookup to make sure that a data message has been directed to the correct session or that any recentlyreused cookie will not be misdirected.

Your web application uses a simple architecture in which servlets handle requests and then forward to aJSP using a request dispatcher. You need to pass information calculated by the servlet to the JSP；furthermore， that JSP uses a custom tag and must also process this information. This information mustNOT be accessible to any other servlet， JSP or session in the webapp. How can you accomplish this goal？（）A、Store the data in a public instance variable in the servlet.B、Add an attribute to the request object before using the request dispatcher.C、Add an attribute to the context object before using the request dispatcher.D、This CANNOT be done as the tag handler has no means to extract this data.
