Answers

1. Correct answer: B

Beginning with SAP NetWeaver 6.10, new technologies based on highly a scalable infrastructure were implemented to process HTTP requests directly from the Internet or to send them as HTTP client requests to the Internet. The SAP kernel was enhanced to include a process known as the Internet Communication Manager (ICM) to achieve this functionality.

2. Correct answer: B

Different SAP NetWeaver components require the SAP NetWeaver Application Server to be run with certain stacks configured. It is possible to install both the ABAP and Java stacks, but depending on the use of the server, it is possible to use just ABAP or just Java.

3. Correct answers: B, D, F

You can use the system administration functions to switch a work process while the system is running. Because each work process has the same structure, they are interchangeable. All work processes must communicate with the dispatcher (which assigns the user to a work process), but enqueue work processes and spool work processes do not communicate with the database. All communication for a work process occurs with either the dispatcher or the database.

Whereas it is normal to only have one enqueue work process (a single enqueue work process is normally sufficient to perform the required tasks), it is possible to have multiple enqueue work processes running. In SAP NetWeaver Application Server you can have only one lock table, but multiple enqueue work processes, running. Each ABAP application server can contain multiple spool work processes.

4. Correct answer: C

The difference between SAP Basis and SAP NetWeaver is that the platform had become a web server. This included the capabilities to handle HTTP requests and includes a Java stack in addition to the existing ABAP stack. 

5. Correct answer: B

The dispatcher does handle communication between the work process and the user but does not handle communication with external systems. External systems use the gateway for communications.

6. Correct answer: B

This is true for ABAP Push Channels (APC)—not ABAP Message Channels. ABAP Message Channels communicate between ABAP programs.
