200-120 QUESTION 1 Refer to the exhibit. What will Router1 do when it receives the data frame shown? (Choose three.) A. Router1 will strip off the source MAC address and replace it with the MAC address 0000.0c36.6965. B. Router1 will strip off the source IP address and replace it with the IP address 192.168.40.1. C. Router1 will strip off the destination MAC address and replace it with the MAC address 0000.0c07.4320. D. Router1 will strip off the destination IP address and replace it with the IP address of 192.168.40.1. E. Router1 will forward the data packet out interface FastEthernet0/1. F. Router1 will forward the data packet out interface FastEthernet0/2. Correct Answer: ACF Section: Introduction to Cisco IOS Explanation Explanation/Reference: The router will decapsulate the frame, thus removing the source and destination MAC addresses. It will consult its routing table to work out on which interface to send the packet which is going to 192.168.40.5: interface FastEthernet0/2. The router will then encapsulate the packet into a new frame with its own MAC address as the source MAC address and the MAC address of 192.168.40.5 as the destination MAC address. Looking at the ARP table, the MAC address for 192.168.40.5 is 0000.0c07.4320 (the one which has been dynamically learned and has age 9 minutes). So what is the router’s MAC address on this link? The ARP table shows a static entry (no age) for 192.168.40.1 which is 0000.0c36.6965. As it is static, we can conclude that these are the router’s IP and MAC address. QUESTION 2 Refer to the exhibit. Which three statements correctly describe Network Device A? (Choose three.)

Correct Answer: BDE Section: IP Routing Explanation Explanation/Reference: If the device is a Layer 2 transparent device (hub, bridge, switch) then the two PCs must be on the same subnet. The smallest subnet which would contain both of the IP addresses is 10.1.0.0/23 with the range 10.1.0.0 up to 10.1.1.255. The mask for this is 255.255.254.0. On the other hand, if the device is a router, then we would need a netmask smaller than 255.255.254.0 and we would have two subnets.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
