which has a partial configuration and has been attached to RouterC as shown in the topology diagram. You do not have access to RouteC.250. RouterC is correctly configured.200. 13 .200.64/27 Hosts H1 and H2 are configured with the correct IP address and default gateway.10. Note: Due to administrative restrictions and requirements you should not add or delete VLANs.0/24 – 190.10. All routes must be learned via the EIGRP routing protocol. changes VLAN port assignments or create trunks. No trunking has been configured on RouterC. Company policies forbid the use of static or default routing.250. Routing must only be enabled for the specific subnets shown in the diagram. You need to configure SwitchC so that Hosts H1 and H2 can successfully ping the server S1. Company policies forbid the use of static or default routing.Answer: D Question No : 15 CORRECT TEXT You have been tasked with configuring multilayer SwitchC. The following subnets are available to implement this solution: – 10. Also SwitchC needs to be able to ping server S1. Routed interfaces should use the lowest host on a subnet when possible. Due to administrative restrictions and requirements you should not add/delete vlans or create trunk links.32/27 – 190. SwitchC uses Cisco as the enable password. All routes must be learned via EIGRP 65010 routing protocol.

15 . No trunking requires.Answer: There are two ways to configure interVLAN routing in this case: + Use RouterC as a “router on a stick” and SwitchC as a pure Layer2 switch. + Only use SwitchC for interVLAN routing without using RouterC. Trunking must be established between RouterC and SwitchC. SwitchC should be configured as a Layer 3 switch (which supports ip routing function as a router).

0.10.255 SwitchC(config-router)# network 190.10.200.200. also don’t modify/delete any port just do the above configuration. Answer: \>ipconfig We will get the default gateways as follows: Host1: + Default gateway: 190.32 0.255.255.200.31 NOTE: THE ROUTER IS CORRECTLY CONFIGURED. In order to complete the lab. Click on H1 and H2 and type the “ipconfig” command to get their default gateways. the simulator does not let you assign IP address on Gi0/1 interface.10.10.255.0.200.0.255.255.0.255.0 ->RouterC has used IP 10.1 so this is the lowest usable IP address.65 255.31 SwitchC(config-router)# network 190.10.33 Host2: + Default gateway: 190.2 255. We should check the default gateways on H1 & H2.64 0. so you will not miss within it in the exam.0/16 is not used anywhere else in this topology.The question clearly states “No trunking has been configured on RouterC” so RouterC does not contribute to interVLAN routing of hosts H1 & H2 -> SwitchC must be configured as a Layer 3 switch with SVIs for interVLAN routing.250. SwitchC(config-if)# ip address 10.65 Now we have enough information to configure SwitchC (notice the EIGRP AS in this case is 650) Note: VLAN2 and VLAN3 were created and gi0/10. gi0/11 interfaces were configured as access ports so we don’t need to configure them in this sim.0.250. SwitchC# configure terminal SwitchC(config)# int gi0/1 SwitchC(config-if)#no switchport -> without using this command.200. Also some reports said the “no auto-summary” command can’t be used in the simulator.200.0.224 SwitchC(config-if)# no shutdown SwitchC(config-if)# int vlan 3 SwitchC(config-if)# ip address 190.250.250.0. you should expect the ping to SERVER to succeed from the 16 . in fact it is not necessary because the network 190.224 SwitchC(config-if)# no shutdown SwitchC(config-if)#exit SwitchC(config)# ip routing (Notice: MLS will not work without this command) SwitchC(config)# router eigrp 65010 SwitchC(config-router)# network 10.250.33 255.0 0.250.

The command effectively removed all other working VLANs and replaced them with the new VLANs. authorization B. If you use wrong AS number.32 0.200.200.31 we can use one simple command “network 190. accounting D. Question No : 16 Which portion of AAA looks at what a user has access to? A. VTP pruning removed all unused VLANs. C. Allowing additional VLANs across the trunk introduced a loop in the network. Also make sure you use the correct EIGRP AS number (in the configuration above it is 650 but it will change when you take the exam) but we are not allowed to access RouterC so the only way to find out the EIGRP AS is to look at the exhibit above. and from the PCs as well. After the command switchport trunk allowed vlan 10. D.0.0.0 is shown. authentication C. just for sure. But after finishing the configuration.250. In fact. no neighbor relationship is formed between RouterC and SwitchC. 20.MLS. ISL was unable to encapsulate more than the already permitted VLANs across the trunk. even without “no auto-summary” command the network still works correctly. But in the exam the sim is just a flash based simulator so we should use two above commands. we are pretty sure instead of using two commands “network 190. What is the root cause of the problem? A.200. only the summarized network 190.0. Answer: A 17 .30 is issued.0.0 because it is the nature of distance vector routing protocol like EIGRP: only major networks need to be advertised.0.200. B. we can use “show run” command to verify.20. all other existing VLANs no longer pass traffic over the trunk.
