PURPOSE
Short answer questions to assess and reinforce learning of the concepts of Weeks 9-10 by
exploring dashboard data for NOCs.

TASK(S)

Consider the following three possible events that may be highlighted on NOC dashboards:

a) A significant and unusual drop in the number of IP packets being received on the ingress
link for the public Internet.
b) A significant and unusual increase in the rate of duplicate TCP acknowledgements
observed on a Wi-Fi connection.
c) A significant and unusual increase in the number of ARP requests on the internal LAN.
At the same time, you notice that you are unable to access a network file share on the
LAN.

Select two of the above events and, for each selected event, explain the likely cause of the
event and why the indicated symptoms would be observed.



Note: If you address more than options the third cannot be marked/considered.


1 Approximate length is only an estimate and does not include title page, contents page, references, or
illustrations, i.e., the length is indicative of the text of your answer only. Indicated length is based on sensible
settings, e.g., 2cm margins, 12 point font, reasonable spacing. Whilst there is no penalty for an over-sized answer,
note that excessively large answers are likely to lack clarity and can even demonstrate a lack of understanding.
