1. The SIP factory includes a method to generate new Application Sessions.

Explanation

The statement is true because the SIP factory, which stands for Session Initiation Protocol factory, is responsible for creating and managing application sessions. These sessions are essential for establishing and maintaining communication between different devices or applications using the SIP protocol. Therefore, the SIP factory must have a method to generate new application sessions in order to facilitate this communication process.

2. The body of a SIP message can contain a different protocol message embedded.

Explanation

The body of a SIP message can contain a different protocol message embedded, which means that it can include messages from other protocols such as HTTP or XML. This allows for flexibility and interoperability between different communication protocols, making it easier for SIP to work with other systems and applications.

Submit
3. A request will be processed within a servlet in the most spcific handling method (doInvite, for instance, instead of doRequest).

Explanation

The statement is true because within a servlet, there are specific handling methods such as doInvite, doRequest, etc. These methods are responsible for processing different types of requests. In this case, the request will be processed in the most specific handling method, which is doInvite. This means that the servlet will prioritize processing the request using the doInvite method rather than a more general method like doRequest.

Submit
4.
Logical entity that generates a response to a SIP request.

Explanation

A UAS (User Agent Server) is a logical entity that generates a response to a SIP (Session Initiation Protocol) request. It is responsible for accepting incoming requests, processing them, and generating appropriate responses. In SIP communication, the UAS acts as the endpoint that receives and responds to requests from User Agent Clients (UACs). The UAS plays a crucial role in establishing and managing communication sessions between SIP devices.

Submit
5. A SIP request must contain an error or success code.

Explanation

A SIP request does not necessarily have to contain an error or success code. While it is common for SIP responses to include these codes, a request is simply a message sent by a client to a server to initiate a session or perform a specific action. The response to the request may contain an error or success code, but the request itself does not require one.

Submit
6. These are IMS network components.

Explanation

The correct answer includes the IMS network components CSCF, HSS, and Application Server. CSCF stands for Call Session Control Function, which is responsible for controlling and managing the signaling and session setup in the IMS network. HSS stands for Home Subscriber Server, which stores subscriber data and authentication information. The Application Server is responsible for providing various services and applications in the IMS network. These components work together to ensure efficient and secure communication within the IMS network.

Submit
7. Is an "umbrella" object which can store application-specific data and correlate protocol sessions.

Explanation

A SIP Application session is an "umbrella" object that can store application-specific data and correlate protocol sessions. This means that it can store information related to a specific application running on the SIP protocol, allowing for the correlation of different sessions within that application. This is different from a SIP session, which refers to a specific communication session using the SIP protocol, and an HTTP session, which refers to a session using the HTTP protocol. The Session Description Protocol is a protocol used for describing multimedia sessions, and is not directly related to storing application-specific data. Therefore, the correct answer is SIP Application session.

Submit
8.
Logical entity that creates a new request, and sends it.  The role of this entity 
lasts only for the duration of that transaction.

Explanation

A UAC (User Agent Client) is a logical entity that creates a new request and sends it. It is responsible for initiating communication and making requests to a server. The role of the UAC only lasts for the duration of that transaction, meaning it is only active during the specific request it creates and sends.

Submit
9. Receives a request, forwards it and waits for a response, it keeps the state of the dialog.

Explanation

A B2BUA (Back-to-Back User Agent) is a device or software application that receives a request, forwards it to the appropriate destination, and then waits for a response. It also keeps track of the state of the dialog, allowing it to handle complex call scenarios. Unlike other options listed (UA, UAC, UAS), a B2BUA is specifically designed to act as an intermediary in SIP (Session Initiation Protocol) communications, providing advanced call control and manipulation capabilities. Therefore, the correct answer is B2BUA.

Submit
10. One of the SIP container responsibilities is the mapping  of requests to responses.

Explanation

SIP (Session Initiation Protocol) containers are responsible for managing and controlling sessions in a VoIP (Voice over Internet Protocol) network. While SIP containers handle various tasks such as session setup, teardown, and signaling, the mapping of requests to responses is not one of their specific responsibilities. This task is typically handled by the SIP server or proxy, which analyzes the incoming requests and determines the appropriate response to send back. Therefore, the statement that one of the SIP container responsibilities is the mapping of requests to responses is false.
