Q88. CORRECT TEXT - (Topic 7)
Central Florida Widgets recently installed a new router in their office. Complete the network installation by performing the initial router configurations and configuring R1PV2 routing using the router command line interface (CLI) on the RC.
Configure the router per the following requirements:
Name of the router is R2
Enable. secret password is cisco
The password to access user EXEC mode using the console is cisco2
The password to allow telnet access to the router is cisco3
IPV4 addresses mast be configured as follows:
Ethernet network 126.96.36.199/27 - router has fourth assignable host address in subnet
Serial network is 192.0.2.176/28 - router has last assignable host address in the subnet.
Interfaces should be enabled.
Router protocol is RIPV2
In practical examinations, please note the following, the actual information will prevail.
1. Name or the router is xxx
2. EnablE. secret password is xxx
3. Password In access user EXEC mode using the console is xxx
4. The password to allow telnet access to the router is xxx
5. IP information
