Question

Lab Simulation 65 Please use the "Tasks" and "Topology" tabs to complete this lablet. Topology Tasks Task 1 Complete the configuration of NAT/PAT on the R1 router using the predefined configuration. R1 Predefined Configuration interface Ethernet0/0 ip nat outside interfaceEthernet0/1 ip nat inside access-list 192 permit ip 192.168.0.0 0.0.3.255 any Task Configure NTP on R1 and Sw1 using the following information: - NTP server = R1 - Source = Loopback 0 - Client = Sw1 Task 3 R1 is preconfigured with a DHCP pool and associated information. PC1 is configured to obtain an IP address automatically. - Configure a relay agent on Sw1. Task 4 Sw1 is preconfigured with a local user account and a domain name. Complete the SSH configuration on Sw1. - RSA Key = 2048 bits - SSH Version = 2 Answer: Task 1 - Complete NAT/PAT on R1 Predefined config already contains: ip nat inside ip nat outside access-list 192 permit ip 192.168.0.0 0.0.3.255 any Add the missing PAT rule: R1# conf t ip nat inside source list 192 interface e0/0 overload PAT requires mapping ACL 192 to the outside interface with overload. Task 2 - Configure NTP (R1 = server, Sw1 = client, source = Loopback0) R1 (NTP Server) R1# conf t interface Loopback0 ip address 10.1.1.1 255.255.255.255 ! example; use lab IP if different ntp master ntp source Loopback0 Sw1 (NTP Client) Sw1# conf t ntp server 10.1.1.1 ntp source vlan 1 ! or relevant SVI used for management NTP server sets its time source to Loopback0; Sw1 points to R1 as the server. Task 3 - Configure DHCP Relay on Sw1 R1 is the DHCP server. Sw1 must forward DHCP broadcasts. On Sw1, enable the helper on the VLAN interface used by PC1/PC2 (likely VLAN 1 unless otherwise specified): Sw1# conf t interface vlan 1 ip helper-address 172.16.0.9 ! R1 E0/1 IP from topology forwards DHCP requests toward R1. ip helper-address Task 4 - Complete SSH Configuration on Sw1 (RSA 2048, SSHv2) Sw1 already has username + domain name; generate key and enable SSH: Sw1# conf t crypto key generate rsa modulus 2048 ip ssh version 2 line vty 0 4 transport input ssh login local SSH requires an RSA key and SSH version 2. VTY lines must accept SSH and use local authentication.

Explanation

The correct answer systematically addresses all four tasks in sequence: Task 1 completes PAT by adding 'ip nat inside source list 192 interface e0/0 overload' which ties the ACL to the outside interface with overload (PAT); Task 2 configures R1 as NTP master with a Loopback0 source and Sw1 as the NTP client pointing to R1's loopback; Task 3 adds 'ip helper-address' on Sw1's SVI to relay DHCP broadcasts to R1's DHCP server; Task 4 generates a 2048-bit RSA key and sets SSH version 2 on Sw1, completing the SSH configuration that leverages the pre-existing local user account and domain name.
