2. Fraser Coast;
3. Springfield
4. Ipswich.
And each campus has more than 20 buildings, 200 subnets, and
over 1,000 users.
The routers used in USQ College are not supplied by Cisco.
RIP, EIGRP, OSPF are some of the common routing protocols
used in Cisco routers. Which one would
you use if you are the network administrator for USQ College?
Present your arguments:
s.
(e.g.

15. “Which one is better: Banana or Orange?”
Banana is better:
Banana has a cheaper price, around $2 per kg [Peter, 2001].
It is easy to peel [Paul, 2012] and would not make a mess
during consumption [Pearson, 2010].
…
Orange is better:
Orange is available all year round [Mary, 1918].
It stay fresh much longer than Banana [Alice, 2015].
…
My conclusion is that Banana is better than orange because … //
