Q. Are the current 4G (LTE) networks Standalone (SA) or Non-Standalone (NSA)?
a) Standalone (SA)
b) Non-Standalone (NSA)
c) Both SA and NSA possible
d) Neither SA nor NSA

Correct answer: Letter a.
4G LTE networks are designed as Standalone (SA) systems. LTE was deployed with its own core network (EPC - Evolved Packet Core) and does not require another generation’s core network for operation, unlike 5G NSA, which depends on LTE’s core.
Q. Are the current 4G (LTE) networks Standalone (SA) or Non-Standalone (NSA)?
a) 
Standalone (SA)
→ Correct. 4G LTE networks are Standalone (SA) by design, operating with the LTE core network (EPC).
b) 
Non-Standalone (NSA)
→ Incorrect. NSA architecture refers to 5G leveraging 4G LTE cores — not applicable to LTE itself.
c) Both SA and NSA possible
→ Incorrect. LTE is fundamentally SA. NSA applies to 5G deployments that anchor on 4G LTE.
d) Neither SA nor NSA
→ Incorrect. LTE fits into the Standalone category.
