Question: In a 3GPP SIM-ME interface, when executing a SEEK command on a linear fixed EF with an undefined record pointer, where does the search begin for modes 'from the next location forwards' and 'from the previous location backwards', respectively?
Option 1: First record / Second record
Option 2: Last record / First record
Option 3: Middle record / Middle record (for both)
Option 4: First record / Last record
Explanation: According to the SEEK command's behavior for linear fixed EFs, if the record pointer has not been previously set, the search begins with the first record when seeking 'from the next location forwards' and with the last record when seeking 'from the previous location backwards'. This ensures a logical starting point for each mode in the absence of a predefined record pointer position.
