Introduction

In this assessment, you will configure devices in an IPv4/IPv6 network. For the sake of time, you will not be asked to perform all configurations on all network devices as you may be required to do in a real network or other assessment. Instead, you will use the skills and knowledge that you have learned in the labs in this course to configure the Town Hall router . In addition, you will address the hosts on two LANs with IPv4 and IPv6 addresses, activate and address the management interface of the Administration Switch , and back up a device configuration to a TFTP server.

You will receive one of several topologies.

You are not required to configure the IT Department Switch, and you will not be able to access it in this practice skills assessment activity.

All IOS device configurations should be completed from a direct terminal connection to the device console. In addition, many values that are required to complete the configurations have not been given to you. In those cases, create the values that you need to complete the requirements. For values that have been supplied to you, they must be entered exactly as they appear in order for you to get full credit for your configuration.

You will practice and be assessed on the following skills: 
• Configuration of initial IOS device settings
• Design and calculation of IPv4 addressing
• Configuration of IOS device interfaces including IPv4 and IPv6 addressing when appropriate
• Addressing of network hosts with IPv4 and IPv6 addresses
• Enhancing device security, including configuration of the secure transport protocol for remote device configuration
• Configuration of a switch management interface

Requirements by device:

Town Hall router :

• Configuration of initial router settings
• Interface configuration and IPv4 and IPv6 addressing
• Device security enhancement or device hardening
• Secure transport for remote configuration connections as covered in the labs
• Backup of the configuration file to a TFTP server

Administration Switch :

• Enabling basic remote management by Telnet

PC and Server hosts:

• IPv4 full addressing
• IPv6 addressing

Addressing Table

Instructions

Step 1: Determine the IP Addressing Scheme.

Design an IPv4 addressing scheme and complete the Addressing Table based on the following requirements. Use the table to help you organize your work.

a. Subnet the 192.168.1.0/24 network to provide 30 host addresses per subnet while wasting the fewest addresses.
b. Assign the fourth subnet to the IT Department LAN.
c. Assign the last network host address (the highest) in this subnet to the G0/0 interface on Town Hall/CS Department . (192.168.1.126)
d. Starting with the fifth subnet, subnet the network again so that the new subnets will provide 14 host addresses per subnet while wasting the fewest addresses.
e. Assign the second of these new 14-host subnets to the Administration LAN.
f. Assign the last network host address (the highest) in the Administration LAN subnet to the G0/1interface of the Town Hall router. (192.168.1.158)
g. Assign the second to the last address (the second highest) in this subnet to the VLAN 1 interface of the Administration Switch . (192.168.1.157)
h. Configure addresses on the hosts using any of the remaining addresses in their respective subnets.

Step 2: Configure the Town Hall router .

a. Configure the Town Hall router  with all initial configurations that you have learned in the course so far:
• Configure the router hostname: Middle
• Protect device configurations from unauthorized access with the encrypted privileged exec password.
• Secure all access lines into the router using methods covered in the course and labs.
• Require newly-entered passwords must have a minimum length of 10 characters.
• Prevent all passwords from being viewed in clear text in device configuration files.
• Configure the router to only accept in-band management connections over the protocol that is more secure than Telnet, as was done in the labs. Use the value 1024 for encryption key strength.
• Configure local user authentication for in-band management connections. Create a user with the name netadmin and a secret password of Cisco_CCNA5 Give the user the highest administrative privileges. Your answer must match these values exactly.
b. Configure the two Gigabit Ethernet interfaces using the IPv4 addressing values you calculated and the IPv6 values provided in the addressing table.
• Reconfigure the link local addresses to the value shown in the table.
• Document the interfaces in the configuration file.

Step 3: Configure the Administration Switch .

Configure Administration Switch  for remote management over Telnet.

Step 4: Configure and Verify Host Addressing.

a. Use the IPv4 addressing from Step 1 and the IPv6 addressing values provided in the addressing table to configure all host PCs with the correct addressing.
b. Use the router interface link-local address as the IPv6 default gateways on the hosts.

Step 5: Backup the Configuration of the Town Hall router  to TFTP.

a. Complete the configuration of the TFTP server using the IPv4 addressing values from Step 1 and the values in the addressing table.
b. Backup the running configuration of Town Hall  to the TFTP Server. Use the default file name.

12. Which factor determines TCP window size?

the amount of data to be transmitted

the number of services included in the TCP segment

the amount of data the destination can process at one time*

the amount of data the source is capable of sending at one time

 

13. During a TCP session, a destination device sends an acknowledgment number to the source device. What does the acknowledgment number represent?

the total number of bytes that have been received

one number more than the sequence number

the next byte that the destination expects to receive*

the last sequence number that was sent by the source

 

14. What information is used by TCP to reassemble and reorder received segments?

port numbers

sequence numbers*

acknowledgment numbers

fragment numbers

 

15. What does TCP do if the sending source detects network congestion on the path to the destination?

The source host will send a request for more frequent acknowledgments to the destination.

The source will decrease the amount of data that it sends before it must receive acknowledgements from the destination.*

The destination will request retransmission of the entire message.

The source will acknowledge the last segment that is sent and include a request for a smaller window size in the message.

 

16. What is a characteristic of UDP?

UDP datagrams take the same path and arrive in the correct order at the destination.

Applications that use UDP are always considered unreliable.

UDP reassembles the received datagrams in the order they were received.*

UDP only passes data to the network when the destination is ready to receive the data.

 

17. What does a client do when it has UDP datagrams to send?

It just sends the datagrams.*

It queries the server to see if it is ready to receive data.

It sends a simplified three-way handshake to the server.

It sends to the server a segment with the SYN flag set to synchronize the conversation.

 

18. What happens if the first packet of a TFTP transfer is lost?

The client will wait indefinitely for the reply.

The TFTP application will retry the request if a reply is not received.*

The next-hop router or the default gateway will provide a reply with an error code.

The transport layer will retry the query if a reply is not received.

 

19. A host device is receiving live streaming video. How does the device account for video data that is lost during transmission?

The device will immediately request a retransmission of the missing data.

The device will use sequence numbers to pause the video stream until the correct data arrives.

The device will delay the streaming video until the entire video stream is received.

The device will continue receiving the streaming video, but there may be a momentary disruption.*

 

20. Why does HTTP use TCP as the transport layer protocol?

to ensure the fastest possible download speed

because HTTP is a best-effort protocol

because transmission errors can be tolerated easily

because HTTP requires reliable delivery*

 

21. When is UDP preferred to TCP?

when a client sends a segment to a server

when all the data must be fully received before any part of it is considered useful

when an application can tolerate some loss of data during transmission*

when segments must arrive in a very specific sequence to be processed successfully

 

22. Which three application layer protocols use TCP? (Choose three.)

SMTP*

FTP*

SNMP

HTTP*

TFTP

DHCP

23. Refer to the exhibit. Consider a datagram that originates on the PC and that is destined for the web server. Match the IP addresses and port numbers that are in that datagram to the description. (Not all options are used.)
