CCNA: Routing and Switching Essentials SA Exam
Scenario
In this Skills Assessment (SA) you will configure a small network. You will configure routers, switches, and
PCs to support IPv4 connectivity, switch security, and inter VLAN routing. You will then configure the devices
with OSPFv2, DHCP, and dynamic and static NAT. Access control lists (ACLs) will be applied for added
security. You will test and document the network using common CLI commands throughout the assessment.

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many
interfaces the router has. There is no way to effectively list all the combinations of configurations for each router
class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device.
The table does not include any other type of interface, even though a specific router may contain one. An
example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be
used in Cisco IOS commands to represent the interface.
