Carefully examine the topology and its description below before answering any of the questions. Note that all switches are Cisco Catalyst model 2960 switches. 1. All identified ports are up/up and all configurations are at factory defaults except as noted below: $1: int f0/3 & f0/5 access mode in VL10 int f0/6 access mode in VL20 int f0/1 trunking all vlans allowed 52: int f0/7 access mode in VL10 int f0/8 access mode in VL20 int f0/10 trunking all vlans allowed Link from $2 int f0/20 to R1 int f0/0 is not configured Host IP Addressing: H1: 192.168.3.10/24, GW: 192.168.3.1 0 H2: 192.168.2.20/24, GW: 192.168.2.1 H3: 192.168.3.30/24, GW: 192.168.3.1 H4: 192.168.2.40/24, GW: 192.168.2.1 H5: 192.168.3.50/24, GW: 192.168.3.1 H6: 192.168.10.50/24, GW: 192.168.10.1 -66 H6 All MAC addresses shown, are: 00-00-0c-11-11-nn 10/21 -22 H2 -44 HA S3 f0/6 f0/8 f0/22 10/3 10/2 -CC $1 10/1 10/10 S2 10/20 f0/0 -aa R1 f0/5 f0/7 -33 H3 -55 H5 Questions: 1. Consider H1 sending an ARP request for its default gateway. Explain the movement of the ARP request identifying the device(s)/port(s) through which it propagates. YOU DO NOT NEED TO DESCRIBE HOW THE CONTENT OF THE MAC ADDRESS TABLE IS AFFECTED BY H1's ARP REQUEST. 2. Will H1 receive a reply to its ARP request for its default gateway (Y or N and explain why)? 3. Identify/describe the additional configuration actions that MAY be needed at the various devices to achieve full L3 reachability between hosts H1 and H2. o additional configuration actions at S1 additional configuration actions at S2 additional configuration actions at R1 for router-on-a-stick interVlan routing Question 15 (3 points) Saved You have been asked to assist in troubleshooting a network problem. Specifically, you have a user with a device connected to switch port f0/10 complaining that they are not able to connect to the network. As a good administrator, you consult the network documentation which reveals that a desktop computer should be connected to port f0/10 (therefore it should be an access port) that should be assigned an IP address associated with vlan 40, the human resources vlan. You are working remotely from home, and your reaction is to login to the switch to verify the Layer 1 and layer 2 status of the port by issuing the following command: show interface f0/10 switchport Your task is to analyze the output of the show interface f0/10 switchport command to verify and confirm that all the applicable values are what you expect them to be based on the network documentation and that a device has layer 1 connectivity to the port f0/10. Please note that your company implements "Vlan best practices". Identify the show interface f0/10 switchport parameter values you would expect to observe for each parameters listed below if the port was properly configured/working. Paragraph Answer: BI Uv Parameter Name Switchport: Administrative Mode: Operational Mode: 44 Expected Parameter Value 0 + v 11. Question 10 (8 points) Saved Consider a network consisting of a group of interconnected switches configured as follows: Vlans 10, 20, 30 and 99 Vlan 10 - HR Vlan 20 - FIN Vlan 30 - Guest Vlan 99 - Management Inter-vlan routing has NOT been configured PCA and PCB are on Vlan 10, PCC is on Vlan 20, PCD is on Vlan 30 and PCE is on Vlan 99 The links between the switches are properly operating as 802.1q trunk links carrying traffic for vlans 10, 20, 30 and 99. Questions: 1. Which modern day switch feature allows a network to be segmented into different broadcast domains? 2. How many broadcast domains exist in this network? 3. PCA sends a frame to destination MAC FFFFFFFFFFFF. Will PCD receive the frame? (Yes or No) and why? 4. What are three configuration best practices for unused switch ports? 5. Which inter-vlan method do you recommend for your network? Provide a brief justification. Assume your switches are capable of only providing layer 2 functions. Paragraph 1. Answers: 2. 3.
