It was mentioned earlier that you should expect the majority of questions you asked during an interview as an ICT Administrator to be either operational or technical.

Anticipate follow-up questions from the interviewer.

"Clustering is connecting two or more computers in a manner that enables them to behave as a single data processor. The purpose of this is to create a parallel processing environment, perform a load balancing and establish fault tolerance."
