SRWE Practice PT Skills Assessment (PTSA) – Part 1 (Answers Version)

Answers Note: Red font color or gray highlights indicate text that appears in the Answers copy only.

Answers Version

This assessment activity is designed to provide practice in preparation for the final Skills Assessment in this course. This activity uses variables to create variations of this assessment that are presented to the student. The variations consist of changes to the topology layout and labeling and the names of the devices. These device naming variations appear in the instructions as well as the topologies. This means that students will receive different versions of the assessment that combine different names and labels with different topology layouts. There are a number of possible combinations. Each time the student starts the assessment, they will receive a different variation unless they are resuming work on a previously saved assessment.

In the instructions below, values that are contained in double brackets, such as [[Router0Name]], are placeholders for values that will vary for each assessment. Students will not see the double-bracketed terms, instead they will see the device names and labels for their version of the activity.

The variations that students will receive do not affect the difficulty of the assessment activities.

In addition, you will find this assessment activity to be more “open-ended” than some of the activities that the student has experienced in the initial portion of the course. As the course progresses, the instructions become less prescriptive, allowing the student the opportunity to get a better measure of their knowledge and skills. More “open-ended” requirements also allow the Answers the opportunity to target misconceptions or weak areas for students. Students are given the overall requirement to complete or goal to achieve but not the specific details on how to achieve success. This presents a more real-world assessment of their preparedness for the tasks and gives them an opportunity to explore where they may need more study and practice before taking the final Skills Assessment for the course. Depending on the nature of the Skills Assessment you will provide to your students, you may want to provide more or less guidance to optimize the learning experience for your students.

A few things to keep in mind while completing this activity:

Do not use the browser Back button or close or reload any exam windows during the exam.
Do not close Packet Tracer when you are done. It will close automatically.
Click the Submit Assessment button in the browser window to submit your work.

Introduction

In this assessment you are configuring a network that is using EtherChannel and routing between VLANs. 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 router and switches in the topology. In addition to EtherChannel and inter-VLAN routing, this task involves creating VLANs and trunks, and performing basic router and switch configuration.

You are required to configure host default gateways; however host addresses are preconfigured.

You will practice and be assessed on the following skills:

 Configuration of initial settings on a router.

 Configuration of initial settings on a switch, including SVI and SSH.

 Configuration of VLANs.

 Configuration of switchport VLAN membership.

 EtherChannel configuration.

 Troubleshooting VLANs.

 Configuration of static trunking and DTP.

 Configuration of routing between VLANs on a Layer 3 switch.

 Configuration of router-on-a-stick inter- VLAN routing on a router.

 Configure default gateways on hosts.

Background / Scenario

A corporation is planning to implement EtherChannel and a new VLAN design in order to make the network more efficient. You have been asked to work on a design and prototype of the new network. You have created the logical topology and now need to configure the devices in order to evaluate the design. You will configure VLANs and access port VLAN membership on access layer switches. You will also configure EtherChannel and trunking. Finally, you will configure a router and a Layer 3 switch to route between VLANs. Some addressing had already been configured.

Instructions

Part 1: Basic Router Configuration

Step 1: Configure router [[routerVar]] with required settings.

Open a command window on router [[routerVar]] and move to privileged EXEC mode.
Copy and paste the following configuration into the [[routerVar]] router CLI.

ip route [[VLAN10Net]] 255.255.255.0 GigabitEthernet0/0/0

ip route [[VLAN20Net]] 255.255.255.0 GigabitEthernet0/0/0

ip route [[VLAN30Net]] 255.255.255.0 GigabitEthernet0/0/0

ip route [[VLAN99L1Net]] 255.255.255.240 GigabitEthernet0/0/0

Be sure to press the <Enter> key after the last line to return to privileged EXEC mode prompt.

Configure the following settings on the router:

The enable secret password.
A console password
Remote access to the VTY lines.
A banner MOTD message.
The device hostname according to the value in the addressing table.
All clear text passwords should be encrypted.
Interface addressing on G0/0/0 and S0/1/0.
Interface descriptions on G0/0/0 and S0/1/0.

Note: Be sure to make a record of the passwords that you create.

Part 2: Basic Switch Configuration

Step 1: Configure Remote Management Addressing

Configure SVI 99 on switch [[LAN2-SW1Var]] with IP addressing according to the Addressing Table.
The [[LAN2-SW1Var]] switch SVI should be reachable from other networks.

Step 2: Configure Secure Remote Access

On switch [[LAN2-SW1Var]], configure SSH as follows:

Username: admin encrypted password: C1sco123!
Modulus bits 1024
All VTY lines should accept SSH connections only
Connections should require the previously configured username and password.
IP domain name: acad.pt

Part 3: VLAN Configuration

Step 1: Configure VLANs according to the VLAN table.

Use the VLAN Table to create and name the VLANs on the appropriate switches.

VLAN Table

VLAN	Name	IP Network	Subnet Mask	Devices
10	[[VLAN10NameVar]]	[[VLAN10Net]]	255.255.255.0	[[multiswitchVar]], [[LAN1-SW1Var]], [[LAN1-SW2Var]]
20	[[VLAN20NameVar]]	[[VLAN20Net]]	255.255.255.0	[[multiswitchVar]], [[LAN1-SW1Var]], [[LAN1-SW2Var]]
30	[[VLAN30NameVar]]	[[VLAN30Net]]	255.255.255.0	[[multiswitchVar]], [[LAN1-SW1Var]], [[LAN1-SW2Var]]
40	[[VLAN40NameVar]]	[[VLAN40Net]]	255.255.255.0	[[LAN2-SW1Var]]
50	[[VLAN50NameVar]]	[[VLAN50Net]]	255.255.255.0	[[LAN2-SW1Var]]
60	[[VLAN60NameVar]]	[[VLAN60Net]]	255.255.255.0	[[LAN2-SW1Var]]
99	[[VLAN99NameVar]]	[[VLAN99L2Net]]	255.255.255.240	[[LAN2-SW1Var]], [[multiswitchVar]]

Step 1: Assign switch ports to VLANs.

Assign VLAN membership to static access switchports according to the Port to VLAN Assignment table.

Port to VLAN Assignment Table

Device	VLAN	VLAN Name	Port Assignments
[[LAN1-SW1Var]]	10	[[VLAN10NameVar]]	F0/7-10
[[LAN1-SW1Var]]	20	[[VLAN20NameVar]]	F0/11-15
[[LAN1-SW1Var]]	30	[[VLAN30NameVar]]	F0/16-24
[[LAN1-SW2Var]]	10	[[VLAN10NameVar]]	F0/7-10
[[LAN1-SW2Var]]	20	[[VLAN20NameVar]]	F0/11-15
[[LAN1-SW2Var]]	30	[[VLAN30NameVar]]	F0/16-24
[[LAN2-SW1Var]]	40	[[VLAN40NameVar]]	F0/1-5
[[LAN2-SW1Var]]	50	[[VLAN50NameVar]]	F0/6-10
[[LAN2-SW1Var]]	60	[[VLAN60NameVar]]	F0/11-15
[[LAN2-SW1Var]]	99	[[VLAN99NameVar]]	F0/24

Part 4: EtherChannel and Trunking Configuration

EtherChannel Port Assignments Table

Channel Group	Devices in Groups	Ports in Group
1	[[multiswitchVar]]	G1/0/1, G1/0/2
1	[[LAN1-SW1Var]]	G0/1, G0/2
2	[[multiswitchVar]]	G1/0/3, G1/0/4
2	[[LAN1-SW2Var]]	G0/1, G0/2
3	[[LAN1-SW1Var]]	F0/5, F0/6
3	[[LAN1-SW2Var]]	F0/5, F0/6

Step 1: Configure EtherChannels

Create EtherChannels according to the EtherChannel Port Assignments Table. Use the Cisco LACP protocol. Both sides of the channel should attempt to negotiate the link protocol.

Step 2: Configure Trunking on the EtherChannels

Configure the port channel interfaces as static trunks. Disable DTP negotiation on all trunks.
Troubleshoot any issues that prevent the formation of the EtherChannels.

Note: Packet Tracer requires configuration of trunking and DTP mode on both portchannel interfaces and the component physical interfaces.

Step 3: Configure a static trunk uplink

On the [[LAN2-SW1Var]] switch, configure the port that is connected to [[routerVar]] G0/0/0 as a static trunk.
Configure the [[VLAN99NameVar]] VLAN as the native VLAN.
Disable DTP on the port.

Part 5: Configure Inter-VLAN Routing

Step 1: Configure inter-VLAN routing on the Layer 3 switch.

Configure Inter-VLAN routing on the [[multiswitchVar]] Layer 3 switch for all VLANs in the VLAN Table that are configured on [[multiswitchVar]].
Configure the switchport on [[multiswitchVar]] that is connected to [[routerVar]] with an IP address as shown in the Addressing Table.

Step 2: Configure router-on-a-stick inter-VLAN routing on a router.

Configure inter-VLAN routing on [[routerVar]] for all the VLANs that are configured on the [[LAN2-SW1Var]] switch. Use the information in the Addressing Table.
Be sure to configure descriptions of all interfaces.

Step 3: Configure default gateways on hosts.

Configure default gateway addresses on all hosts on the LANs.
Verify connectivity between all hosts on both LANs with each other and the [[serverVar]] server.
Verify that a host can connect to the SVI of switch [[LAN2-SW1Var]] over SSH.
