Question: What is the cause value for a semantically incorrect message in the Non-Access Stratum (NAS) protocol for Evolved Packet System (EPS)?
Option 1: #94 - Message type not compatible with the current EPS bearer context.
Option 2: #95 - Semantically incorrect message.
Option 3: #96 - Invalid mandatory information element.
Option 4: #111 - Protocol error, unspecified.
Explanation: The correct answer is Option 2 because cause value #95 specifically refers to a semantically incorrect message as per the NAS protocol for EPS. This cause value indicates that the message received by the network or UE contains semantic errors and cannot be processed further.
