In order to ensure constant redundancy and fault-tolerance, which of the following type of spare is recommended?
A.
Cold spare
B.
Warm spare
C.
Hot spare
D.
Archives
Explanation:
C: A cold spare is a spare component that is not powered up but is a duplicate of the primary component that can be inserted into the system if needed. Warm spares are those that are already inserted in the system but do not receive power unless they are required. Hot spares stay powered on and waiting to be called upon as needed. Archives are data backups stored for historical purposes. To ensure constant redundancy and fault-tolerance, hot spare is the best option. Page 545.
