Quiz on OpenAirInterface (OAI)

1. What is the main purpose of the Access and Mobility Management Function (AMF) in OpenAirInterface (OAI)?

a. It facilitates the transmission of user data packets between gNodeB and the network.
b. It maintains the NAS (Non Access stratum) signaling connection with the User Equipment (UE) and manages the registration process.
c. It maintains an updated repository of all the Network Functions (NFs) available in the operator’s network.
d. It manages data for access authorization, user registration, and data network profiles.

2. What does the Unified Data Repository (UDR) in OAI do?

a. It facilitates the transmission of user data packets between gNodeB and the network.
b. It maintains the NAS (Non Access stratum) signaling connection with the User Equipment (UE) and manages the registration process.
c. It maintains an updated repository of all the Network Functions (NFs) available in the operator’s network.
d. It offers a unified database for storing application, subscription, authentication, service authorization, policy data, session binding, and Application state information.

3. What is the role of the Session Management Function (SMF) in OAI?

a. It facilitates the transmission of user data packets between gNodeB and the network.
b. It maintains the NAS (Non Access stratum) signaling connection with the User Equipment (UE) and manages the registration process.
c. It plays a central role in establishing, modifying, and terminating user sessions in the 5G network.
d. It offers a unified database for storing application, subscription, authentication, service authorization, policy data, session binding, and Application state information.

4. What is the purpose of the build_oai script in the OpenAirInterface (OAI) project?

a. It is used to build different components of OAI, such as the eNodeB and User Equipment (UE) components.
b. It is used to create the directory structure of the OAI project.
c. It is used to manage the licensing of the OAI project.
d. It is used to handle the communication between the Radio Access Network (RAN) and the Core Network (CN).

5. What does the configmodule_interface_t structure do in the OpenAirInterface (OAI) project?

a. It stores all the necessary information for the configuration of the OAI system.
b. It is used to implement the physical layer of the radio access network (RAN).
c. It is used to manage the build process of the OAI project.
d. It is used to handle the communication between the Radio Access Network (RAN) and the Core Network (CN).

6. What is the role of Software Defined Radios (SDRs) in the context of OpenAirInterface (OAI)?

a. SDRs are used to implement the physical layer of the Radio Access Network (RAN).
b. SDRs are used to create an IP route between gNB and NRUE.
c. SDRs are used to test the connectivity between gNB and NRUE.
d. SDRs are used to set up the Core Network (CN).

7. What is the purpose of creating an IP route in the process of setting up a 5G network with OAI?

a. To implement different wireless standards and protocols.
b. To ensure that the gNB can communicate with the CN through the specified network interface.
c. To configure the software parameters such as the frequency band, transmission power, and other radio parameters.
d. To verify that the gNB and NRUE are correctly set up and can communicate with each other over the IP network.
