What are some likely causes of network interruption or failure?
What will be an ideal response?
In addition to the security issues discussed in the last chapter, a number of innocuous causes can lead to failure of a network link or network device.These can include software bugs, traffic overload, factory defects, components wearing out, electrical surges, line breaks, traffic issues such as broadcast storms, and human error such as misconfiguration.Fixing these issues is nontrivial and will likely vary by cause.One of the issues you should raise in discussing this list is the time involved in identifying the root cause of the failure or even the location of the failure.Issues such as a line break will likely be more physically demanding than a misconfiguration, although identifying the failure may be as time consuming for both issues.
