Answers to Chapter 7 "Do I Know This Already?" Quiz
1
Define the acronyms SOHO and RO.
They stand for small office/home office and remote office. The difference between them
is slight: the 700 is positioned for a SOHO and not generally positioned for a RO. This
should be remembered when selecting equipment during the test.
2
What are the three permanent profiles for the 700 series router?
The profiles are LAN, standard, and internal.
3
For what is the internal profile used?
The internal profile is used when routing is enabled and provides the configuration
parameters to pass data between the bridge engine and the IP/IPX route engine.
4
How many user profiles can be created?
Sixteen user profiles can be created. A total of 20 profiles is allowed on the device;
however, the LAN, standard, internal, and system profiles also count toward the 20.
5
Can an ISP support dial-on-demand (DDR) routing and bandwidth-on-demand (BoD)
with a 700 series router? If not, why?
Both DDR routing and BoD are supported on the device, not the ISP. DDR is controlled
by the 700, and BoD is supported with the Multilink PPP option, if negotiated during the
LCP setup. This question is tricky.
6
What is the mechanism that points the 700 to the ISP?
The static route that is in the profile that dials the ISP is the mechanism that enables the
700 series router to route packets to the ISP. In general, the route to the ISP would be the
default, or all 0s, route.
7
What routing protocols can be configured on the 700 series router?
The RIP-1 and RIP-2 routing protocols can be configured on the 700 series router.
