Sample question (from the 65-question bank)
Q. Note that SUCI conceals the subscriber identity using ECIES. From a SOC perspective, why does this still leave SS7/Diameter location-tracking of 5G subscribers possible?
- A.SUCI guards the air interface; SS7 the legacy layer
- B.Because SUCI is reversible by any SS7 node
- C.Because the AMF forwards every UE location update directly onto the SS7 network by design
- D.Because ECIES keys are shared with all roaming partners
