Introduction


As far as network administration goes, nothing is more important than fault tolerance and disaster recovery. First and foremost, it is the responsibility of the network administrator to safeguard the data held on the servers and to ensure that when requested, this data is ready to go.

Because both fault tolerance and disaster recovery are such an important part of network administration, they are well represented in the CompTIA Network+ exam. In that light, this chapter is important both in terms of real-world application as well as the exam itself.

Before diving into the fault tolerant and disaster recovery objectives, we will start this chapter by reviewing the function of virtual LANs (VLANS).
