  1. In MySQL, the default size of the key buffer in MB is _________________.
    1. 32
    2. 16
    3. 8
    4. 4
    5. None of these
Correct Option: C

The larger values allow MySQL to hold more index blocks in memory at once. This increases the chances of finding key values in memory without having to read a new block from disk.
