CCNAv7 ITN Skills Assessment – ITN Final Skills Exam (Equipment) Exam Answers

Topology

Assessment Objectives

• Part 1: Develop an IP Addressing Scheme (20 points, 25 minutes)
• Part 2: Initialize and Reload Devices (10 points, 20 minutes)
• Part 3: Configure Device IP address and Security Settings (45 points, 35 minutes)
• Part 4: Test and Verify IPv4 and IPv6 End-to-End Connectivity (15 points, 20 minutes)
• Part 5: Use the IOS CLI to Gather Device Information (10 points, 10 minutes)

Scenario

In this Skills Assessment (SA) you will configure the devices in a small network. You must configure a router, switch and PCs to support both IPv4 and IPv6 connectivity. You will configure security, including SSH, on the router. In addition, you will test and document the network using common CLI commands.

Required Resources

• 1 Router (Cisco 4221 with Cisco IOS XE Release 16.9.4 universal image or comparable)
• 1 Switch (Cisco 2960 with Cisco IOS Release 15.2(2) lanbasek9 image or comparable)
• 2 PCs (Windows with a terminal emulation program, such as Tera Term)
• Console cables to configure the Cisco IOS devices via the console ports
• Ethernet cables as shown in the topology

Instructions

Part 1: Develop an IP Addressing Scheme

• Total points: 20
• Time: 25 minutes

a. Your instructor will assign one of the IPv4 networks from the table below. You will subnet it to provide IP addresses to two subnets that will support the required number of hosts. No subnet calculators may be used. All work must be shown using the IP Addressing worksheet below.

IP Addressing Worksheet

• 1) Assign the first IPv4 address of each subnet to a router interface
  • (i) subnet A is hosted on R1 G0/0/1
  • (ii) subnet B is hosted on R1 G0/0/0
• 2) Assign the last IPv4 address of each subnet to the PC NIC
• 3) Assign the second IPv4 address of subnet A to S1
• 4) List the maximum number of useable hosts per subnet

c. Record the IP address information for each device:

d. Use the IPv6 address 2001:db8:acad::/48 and create two subnets for use in this network. Record the IPv6 addresses in the table.

e. Record the IPv6 address information for each device.
Note: Use FE80::1 as the link-local address on both router interfaces.

Before proceeding, verify your IP addressing scheme with the instructor.

Part 2: Initialize and Reload Devices

• Total points: 10
• Time: 20 minutes

• Erase the startup configurations and VLANs from the router and switch and reload the devices.
  On Switch

  Switch>enable
  Switch#erase startup-config
  Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]
  [OK]
  Erase of nvram: complete
  %SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram
  Switch#delete vlan.dat
  Switch#reload
  Proceed with reload? [confirm]

  On Router

  Router>enable
  Router#erase startup-config
  Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]
  [OK]
  Erase of nvram: complete
  %SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram
  Router#reload
  Proceed with reload? [confirm]
  Initializing Hardware ...
  
  Would you like to enter the initial configuration dialog? [yes/no]: no

• After the switch is reloaded, change the SDM template to one that supports IPv6 as necessary, and reload the switch again.
  On Switch:

  Switch>
  Switch>enable
  Switch#configure terminal 
  
  Switch(config)#sdm prefer dual-ipv4-and-ipv6 default
  Changes to the running SDM preferences have been stored, but cannot take effect until the next reload.
  Use 'show sdm prefer' to see what SDM preference is currently active.
  Switch(config)#exit
  
  Switch#reload

Before proceeding, ask your instructor verify device initializations.

Part 4: Test and Verify End-to-End Connectivity

• Total points: 15
• Time: 10 minutes

Use the ping command to test IPv4 and IPv6 connectivity between all network devices.
Note: If pings to host computers fail, temporarily disable the computer firewall and retest.
Use the following table to methodically verify connectivity with each network device. Take corrective action to establish connectivity if a test fails:

In addition to the ping command, what other command is useful in displaying network delay and breaks in the path to the destination? (1 point)
tracert or traceroute

Part 6: Cleanup

NOTE: DO NOT PROCEED WITH CLEANUP UNTIL YOUR INSTRUCTOR HAS GRADED YOUR SKILLS EXAM AND HAS INFORMED YOU THAT YOU MAY BEGIN CLEANUP.

Unless directed otherwise by the instructor, restore host computer network connectivity, and then turn off power to the host computers.

Before turning off power to the router and switch, remove the NVRAM configuration files (if saved) from both devices.

Disconnect and neatly put away all LAN cables that were used in the Final.

Router Interface Summary Table

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many interfaces the router has. There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device.

The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface.
