CCNA $1$Name $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$Skills Based AssessmentPass $/$ FailVer $3.$ Fall, $2023$IntroductionThere is nothing here you have not done, read carefully. In this skills assessment, you will build a small LAN. You will configure a router, a switch, and enable secure remote access and management of the router and switch. Finally, you will configure hosts to communicate on the LAN.Make sure to verify that there is no configuration present on the equipment and erase as necessary $.$ Addressing Table $(36$ points$)$Create a new IPv$4$ VLSM addressing scheme using the $192\mathrm{.}168\mathrm{.}1\mathrm{.}0/24$ network. $*$ Note: You will not configure all these networks LAN $1$ needs $100$ hosts use subnet $0192\mathrm{.}168\mathrm{.}1\mathrm{.}0255\mathrm{.}255\mathrm{.}255\mathrm{.}128$o Assign the G$0/0/1$ interface the first usable host address in the rangeo Assign the S$1$ VLAN $1$ interface the second usable host address in the rangeo Assign PC$-$A the fifth usable host address in the range LAN $2$ needs $10$ hosts $($not configured$)192\mathrm{.}168\mathrm{.}1\mathrm{.}128255\mathrm{.}255\mathrm{.}255\mathrm{.}240$ LAN $3$ needs $10$ hosts $($not configured$)192\mathrm{.}168\mathrm{.}1\mathrm{.}144255\mathrm{.}255\mathrm{.}255\mathrm{.}240$ LAN $4$ needs $5$ hosts $192\mathrm{.}168\mathrm{.}1\mathrm{.}160255\mathrm{.}255\mathrm{.}255\mathrm{.}248$ o Assign the G$0/0/0$ interface on R$1$ the first usable host address in this rangeo assign PC$-$B the fifth usable host address in this rangeDeviceInterfaceAddressMaskGatewayR$1$G$0/0/1192\mathrm{.}168\mathrm{.}1\mathrm{.}1255\mathrm{.}255\mathrm{.}255\mathrm{.}1282001$:db$8$:$1$:$1$::$1/64$ fe$80$::$1$ G$0/0/0192\mathrm{.}168\mathrm{.}1\mathrm{.}161255\mathrm{.}255\mathrm{.}255\mathrm{.}2482001$:db$8$:$1$:$2$::$2/64$ S$1$VLAN $1192\mathrm{.}168\mathrm{.}1\mathrm{.}2255\mathrm{.}255\mathrm{.}255\mathrm{.}128192\mathrm{.}168\mathrm{.}1\mathrm{.}1$PC$-$ANIC$192\mathrm{.}168\mathrm{.}1\mathrm{.}5255\mathrm{.}255\mathrm{.}255\mathrm{.}128192\mathrm{.}168\mathrm{.}1\mathrm{.}12001$:db$8$:$1$:$1$::$10/64$fe$80$::$1$ fe$80$::$1$ PC$-$BNIC$192\mathrm{.}168\mathrm{.}1\mathrm{.}165255\mathrm{.}255\mathrm{.}255\mathrm{.}248192\mathrm{.}168\mathrm{.}1\mathrm{.}1612001$:db$8$:$1$:$2$::$10/64$fe$80$::$1$ InstructionsStep$1$: Connect the network as shown in Topology: Step$2$: Configure basic settings on the Campus$1$ router. $(9$ points$)$Configure the following: The router name: R$1$ Prevent IOS from attempting to resolve mistyped commands to domain names. Require that newly created passwords be at least $8$ characters in length. Configure an encrypted password to protect the privileged EXEC mode: class$987$ Create a banner message that states $-$ NO UNAUTHORIZED ACCESS The console line should require a password for all logins$.$ Use the password cisco$987$ The VTY lines will use SSH for remote access and will be configured later. All passwords should automatically be encrypted. Block anyone for three minutes who fails to log in after four attempts within a two$-$minute period. Enable IPv$6$ RoutingStep $3$: Configure basic settings on the S$1$ switch. $(5$ points$)$Configure the following: The switch name: S$1$ Prevent IOS from attempting to resolve mistyped commands to domain names. Configure an encrypted password to protect the privileged EXEC mode: class$987$ Create a banner message that states $-$ NO UNAUTHORIZED ACCESS The console line should require a password for all logins$.$ Use the password cisco$987$ The VTY lines will use SSH for remote access and will be configured later. All passwords should automatically be encrypted.Step $4$: Configure the LAN interfaces of the R$1$ router. $(12$ points$)$Configure the interfaces as follows:$1.$ Configure the IPv$4$ addresses according to your addressing scheme$\mathrm{.}2.$ Configure a description for each interface$3.$ Configure the IPv$6$ addresses according to the Addressing Table.Step $5$: Configure remote management on the S$1$ switch. $(2$ points$)$Configure the switch SVI by using the default management interface as follows:$1.$ Address the interface according to the values shown in the addressing table$\mathrm{.}2.$ Enable the interface$\mathrm{.}3.$ Configure the switch so that it is reachable from other networks$($default gateway$).$Step $6$: Configure the R$1$ router and S$1$ switch to use SSH for remote connections. $(14$ points$)$Remote connections to the switch should use SSH to connect. All configured values must match the values provided below exactly. Configure SSH by using the following: Domain name: school.com Generate a $1024-$bit RSA key Create a user named tech The user should be required to use an encrypted password of ciscotech Incoming connections should only use the SSH protocol. Use the local user profiles for authentication. Step $7$: Configure the PCs$.(2$ points$)$Configure hosts as follows. $1.$ Configure the assigned IPv$4$ address, subnet mask, and default gateway settings on PCs using your addressing scheme. $2.$ Assign $10\mathrm{.}0\mathrm{.}0\mathrm{.}10$ as the DNS server for all PCs$.3.$ Assign the IPv$6$ unicast and default gateway on PCs according to the addressing table. Step $8$: Verify Connectivity. $(20$ points$)$The following test should all be successful. If not, you will need to troubleshoot.
