1. ARP poisoning is a technique used to:

b. Install malware on victim machines transforming them into zombie agents.
c. Overwhelm a target server with ACK packers exploiting the nature of the 3 way handshake.

1. When implementing ______________________, a stripe set breaks data into units and stores the units across a series of disks by reading and writing to all disks simultaneously. This provides an increase in performance but it does not provide fault tolerance. A failure of one disk in the set means all data is lost.
