What is the key difference between 5G SA and 5G NSA?

• SA uses 4G core, while NSA uses 5G core

• SA relies on LTE for control, signaling, while NSA does not

• SA uses a pure 5G core network, while NSA depends on 4G EPC

• SA is for Service Affecting, while NSA is Non-Service Affecting

In LTE, which component is responsible for assigning PRBs to users?

• HSS (Home Subscriber Server)

• MME (Mobility Management Entity)

• eNodeB (Evolved Node B)

• PCRF (Policy and Charging Rules Function)

Which 3GPP release first introduced 5G SA?

• Release 15

• Release 16

• Release 14

• Release 17

Why do operators prefer migration to 5G SA in the long run?

• To fully utilize 5G capabilities

• Because it's cheaper than NSA

• It works only with older 4G device

• It doesn't require new spectrum

Which feature is ONLY possible with 5G SA and not NSA?

• URLLC

• eMBB

• DSS

• LTE anchor connectivity

Which Release introduced RedCap (Reduced Capability) for 5G SA?

• Release 15

• Release 17

• Release 18

• Release 19

Which core network component in 4G/LTE is responsible for managing user authentication, mobility, and session establishment?

• eNodeB

• MME

• SGW

• PGW

An operator wants to dedicate a "slice" of its 4G network for emergency services. Can traditional 4G/LTE support network slicing?

• Yes, via QCI prioritization

• No, slicing requires a 5G SA core

• Only with VoLTE

• Only in unlicensed spectrum

Which of the following best describes the role of PRBs in LTE scheduling?

• They define the encryption level for user data

• They determine the physical location of the user

• They are the basic units used by the scheduler to allocate resources

• They store configuration settings for the base station

What is the primary function of the Location Area Code (LAC) in mobile networks?

• To identify the subscriber's phone number

• To determine the encryption method used for calls

• To group cells for efficient mobility and paging management

• To measure signal strength between base stations
