Explanation:
There are two approaches to network maintenance: Interrupt Driven and Structured. Interrupt
Driven is the most basic method of performing network maintenance and is more prevalent in
smaller networks while a structured approach more involved and is more prevalent in larger
networks.
With interrupt driven, everything is reactive. Nothing happens until a problem arises. When
applications start experiencing performance problems, you upgrade links or equipment; when users
have problems, you looking into the problem; when you have a security incident, you review and
improve the security of the network. This approach can have negative effects on long-term health of
the network as things such as upgrades and capacity planning are ignored. Also, the network may
experience more downtime because problems are only resolved after an incident, not prevented.
Using a structured approach, you can potentially reduce the amount of unscheduled downtime by
proactively monitoring and managing your systems. While you can never avoid an interrupt-driven
work entirely (due to unexpected failures), using a structured approach is more efficient and
recommended.
