Which statement best describes the role of the Serving GPRS Support Node (SGSN)?
It converts GPRS packets into PDP format.
It authenticates users and stores location information.
It provides IP addresses for mobile devices.
It controls the power of the mobile station.
What is the main difference between the Class A and Class C modes of GPRS operation?
Class A mode supports both packet-switched and circuit-switched services simultaneously, while Class C only supports circuit-switched.
Class A mode supports packet-switched services only, while Class C supports both packet-switched and circuit-switched services.
Class A mode allows simultaneous operation of GPRS and GSM services, while Class C supports packet-switched data only.
Class A mode supports multiple data flows, while Class C supports a single data flow.
Which GPRS interface is responsible for connecting the Gateway GPRS Support Node (GGSN) to external packet data networks?
Gb interface
Gi interface
Gc interface
Gr interface
What happens when a mobile station initiates the GPRS Attach procedure?
The SGSN assigns an IMSI to the mobile station.
The mobile station requests an IP address for data services.
The HLR authenticates the mobile station and registers it in the SGSN.
The GGSN converts the subscriber’s profile to a GSM format.
Which of the following components of GPRS architecture is responsible for routing and mobility management?
GGSN
SGSN
MSC
BSS
What is the primary function of the Gateway GPRS Support Node (GGSN) in the GPRS network?
It forwards packet-switched data to the SGSN.
It performs user authentication and stores profiles.
It converts GPRS packets into a packet data protocol (PDP) format.
It manages radio channel allocation for mobile stations.
Which component is responsible for packet segmentation and reassembly in the GPRS architecture?
Base Transceiver Station (BTS)
Base Station Controller (BSC)
Packet Control Unit (PCU)
Home Location Register (HLR)
In the GPRS architecture, which node is responsible for detecting and registering a new mobile station (MS) in its area?
GGSN
SGSN
HLR
VLR
Which of the following statements best explains the difference between circuit-switched and packet-switched technologies in GSM and GPRS, respectively?
Circuit-switched is billed based on data transferred, while packet-switched is based on connection duration.
Circuit-switched technology establishes a dedicated connection, while packet-switched technology uses bandwidth more efficiently by sending data in packets.
Circuit-switched technology is used for internet access, while packet-switched technology is used only for voice communication.
Circuit-switched technology allows for simultaneous data and voice transfer, while packet-switched does not.
Which GPRS interface is used to query the IMEI information from the Equipment Identity Register (EIR)?
Gp interface
Gf interface
Gn interface
Gi interface
Which operation mode in GPRS allows the mobile station to use both GSM and GPRS services simultaneously?
Class A
Class B
Class C
Class D
What happens when a mobile station enters the GPRS Detach procedure?
The SGSN assigns a new IMSI key to the mobile station.
The mobile station is disconnected from the GPRS network.
The HLR deletes the subscriber profile from its database.
The GGSN updates the mobile station’s IP address.
Which GPRS node stores the fixed IP address and updates the status of the mobile station?
SGSN
GGSN
HLR
VLR
What is the purpose of the Gb interface in the GPRS network?
It connects the Base Station Controller (BSC) to the Serving GPRS Support Node (SGSN).
It connects the Mobile Station (MS) to the Base Transceiver Station (BTS).
It connects the Gateway GPRS Support Node (GGSN) to external packet data networks.
It connects the SGSN to the Home Location Register (HLR).
In which mode does the GPRS terminal suspend packet data transfer to allow a circuit-switched call and then resume after the call is finished?
Class A
Class B
Class C
Class D
