Q:

If one of the host connected to Sw-AC3 wants to send message to ip 190.0.2.5 (or any ip on a different subnet) what will be the destination MAC address ?

Answer

Answer and Explanation:


Because the destination address is on a different subnet from the switch, the packet will be forwarded to its default gateway. To verify the default gateway of this switch, use the show running-config command



From the output above, we can see that its default-gateway is 192.168.1.254. Which can be said to be a layer 3 device (router); in this case, the VLAN-R1 router. You can use the show cdp neighbor detail command verify further.



From the output above, you can confirm that the switch's default gateway is VLAN-R1 router (with the IP address of 192.168.1.254).The interface FastEthernet0/3 shows that the switch is directly connected to VLAN-R1 router through the switchport Fa0/3. To verify the MAC address associated this interface is interface, you use the show mac-address-table command:



Looking closely at the table above, you will discorver that the corresponding MAC address is 000a.b7e9.8360. Although there are some entries on port Fa0/3 with different Vlans ,but they have the same MAC address.

Q:

A router has learned three possible routes that could be used to reach a destination network. One route is from EIGRP and has a composite metric of 20684570. Another route is from OSPF with a metric of 852. The last is from RIPv2 and has a metric of 4. Which route or routes will the router install in the routing table?

A. the OSPF route
B. the EIGRP route
C. the RIPv2 route
D. all three routes
E. the OSPF and RIPv2 routes

Answer

Answer : B


Explanation :


This is one of those tricky questions just to test your knowledge of routing protocols and their administrative distance. Let’s look at the AD of popular routing protocols below:
 Routing Protocol (Source)                           AdministrativeDistance(AD)                                                             


  Directly connected                                        0


  Static Route                                                  1


  EIGRP                                                           90


  Summary Route(EIGRP)                              5


  OSPF                                                           110


  RIP                                                              120


Fom the above table, you can see that EIGRP has the lowest AD from all of the above mentioned routing protocols. So, the router will choose to use the routing protocol which has lowest Administrative Distance which in this case is B. EIGRP
