Answer to Question 1

Shared locks allow other transactions to read but not update a record or other resource. This is most useful when preventing another user from placing a lock on a record. An exclusive lock prevents another transaction from reading and writing a record until an update is done by the transaction that locked the record.

Answer to Question 2

TRUE
