An exclusive lock locks the item from change but not from read.

  • A.True
  • B.False

Answer: B

Correct answer: False

That describes a shared lock, which permits others to read but not to change. An exclusive lock excludes access of every kind, reading included, which is what a writing transaction requires. Several shared locks may be held on one item at once; an exclusive lock may not coexist with any other.
