Explanation:
The V$SHARED_POOL_RESERVED dynamic performance view is designed to assist in tuning shared-pool reserved-list configuration. An important column is REQUEST_FAILURES, indicating the number of shared pool space requests that weren't granted. If value for this column is always increasing, you should increase SHARED_POOL_SIZE and SHARED_POOL_RESERVED_SIZE.
Incorrect Answers:

1: The LARGE_POOL_SIZE parameter is not related with V$SHARED_POOL_RESERVED view.
2: The LARGE_POOL_SIZE parameter is not related with V$SHARED_POOL_RESERVED view.
4: You should increase, not decrease the SHARED_POOL_SIZE parameter.
6: You should increase, not decrease the SHARED_POOL_RESERVED_SIZE parameter.
