Which memory structures are shared? Choose two.

Answer 3 and 4 - The sort area is allocated to the server process as part of the PGA. The PGA is allocated when the server process starts and is deallocated when the server process completes. The library cache and the large pool are part of the SGA and are shared. The SGA is created when the instance starts.
