• Question 648:

  Lab Simulation - MLS and EIGRP

  You have been tasked with configuring multilayer SwitchC, which has a partial configuration and has been attached to RouterC as shown in the topology diagram. You need to configure SwitchC so that Hosts H1 and H2 can successfully ping

  the server S1. Also SwitchC needs to be able to ping server S1. Due to administrative restrictions and requirements you should not add/delete vlans or create trunk links.

  Company policies forbid the use of static or default routing. All routes must be learned via EIGRP 65010 routing protocol.

  You do not have access to RouteC. RouterC is correctly configured. No trunking has been configured on RouterC. Routed interfaces should use the lowest host on a subnet when possible. The following subnets are available to implement this

  solution:

  -10.10.10.0/24

  -190.200.250.32/27

  -190.200.250.64/27 Hosts H1 and H2 are configured with the correct IP address and default gateway. SwitchC uses Cisco as the enable password. Routing must only be enabled for the specific subnets shown in the diagram. Note: Due to administrative restrictions and requirements you should not add or delete VLANs, changes VLAN port assignments or create trunks. Company policies forbid the use of static or default routing. All routes must be learned via the EIGRP routing protocol.

  A. Check the answer below

  In real life, 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. Trunking must be established between RouterC and SwitchC. + Only use SwitchC for interVLAN routing without using RouterC, SwitchC should be configured as a Layer 3 switch (which supports ip routing function as a router). No trunking requires.

  The question clearly states "No trunking has been configured on RouterC" so RouterC does not contribute to interVLAN routing of hosts H1 and H2 -> SwitchC must be configured as a Layer 3 switch with SVIs for interVLAN routing.

  We should check the default gateways on H1 and H2. Click on H1 and H2 and type the "ipconfig" command to get their default gateways.

  C:\>ipconfig

  We will get the default gateways as follows: Host1:

  +

  Default gateway: 190.200.250.33 Host2:

  +

  Default gateway: 190.200.250.65

  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.

  SwitchC# configure terminal

  SwitchC(config)# int gi0/1

  -> without using this command, the simulator does not let you assign IP address on Gi0/1 interface.

  SwitchC(config-if)#no switchport

  ->RouterC has used IP 10.10.10.1 so this is the lowest usable IP address.

  SwitchC(config-if)# ip address 10.10.10.2 255.255.255.0

  SwitchC(config-if)# no shutdown

  SwitchC(config-if)# exit

  SwitchC(config)# int vlan 2

  SwitchC(config-if)# ip address 190.200.250.33 255.255.255.224

  SwitchC(config-if)# no shutdown

  SwitchC(config-if)# int vlan 3

  SwitchC(config-if)# ip address 190.200.250.65 255.255.255.224

  SwitchC(config-if)# no shutdown

  SwitchC(config-if)#exit

  (Notice: MLS will not work without this command)

  SwitchC(config)# ip routing

  SwitchC(config)# router eigrp 650

  SwitchC(config-router)# network 10.10.10.0 0.0.0.255

  SwitchC(config-router)# network 190.200.250.32 0.0.0.31

  SwitchC(config-router)# network 190.200.250.64 0.0.0.31

  NOTE: THE ROUTER IS CORRECTLY CONFIGURED, so you will not miss within it in the exam , also don't modify/delete any port just do the above configuration. Also some reports said the "no auto-summary" command can't be used in the

  simulator, in fact it is not necessary because the network 190.200.0.0/16 is not used anywhere else in this topology.

  In order to complete the lab , you should expect the ping to SERVER to succeed from the MLS , and from the PCs as well.

  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. If you use wrong AS number, no neighbor relationship is formed between RouterC and SwitchC.

  In fact, we are pretty sure instead of using two commands "network 190.200.250.32 0.0.0.31" and "network 190.200.250.64 0.0.0.31" we can use one simple command "network 190.200.0.0" because it is the nature of distance vector routing

  protocol like EIGRP: only major networks need to be advertised; 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, just

  for sure. But after finishing the configuration, we can use "show run" command to verify, only the summarized network 190.200.0.0 is shown.

• Question 650:

  Which statement about LLDP-MED is true?

  A. LLDP-MED is an extension to LLDP that operates between endpoint devices and network devices.
  B. LLDP-MED is an extension to LLDP that operates only between network devices.
  C. LLDP-MED is an extension to LLDP that operates only between endpoint devices.
  D. LLDP-MED is an extension to LLDP that operates between routers that run BGP.
  A. LLDP-MED is an extension to LLDP that operates between endpoint devices and network devices.

  LLDP for Media Endpoint Devices (LLDP-MED) is an extension to LLDP that operates between endpoint devices such as IP phones and network devices such as switches. It specifically provides support for voice over IP (VoIP) applications

  and provides additional TLVs for capabilities discovery, network policy, Power over Ethernet, and inventory management.
