SRWE PT Practice Skills Assessment (PTSA) Part 1

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

  1. Do not use the browser Back button or close or reload any exam windows during the exam.
  2. Do not close Packet Tracer when you are done. It will close automatically.
  3. 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 R-1 with required settings.

a. Open a command window on router R-1 and move to privileged EXEC mode.

b. Copy and paste the following configuration into the R-1 router CLI.

ip route 172.31.10.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.20.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.30.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.99.0 255.255.255.240 GigabitEthernet0/0/0

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

c. 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.
Router(config)#no ip domain lookup
Router(config)#enable secret class

Router(config)#line console 0
Router(config-line)#password cisco

Router(config-line)#login
Router(config-line)#exit

Router(config)#banner motd #Authorized Access Only!#

Router(config)#hostname R-1

R-1(config)#service password-encryption

R-1(config)#interface g0/0/0
R-1(config-if)#ip address 172.31.0.1 255.255.255.0
R-1(config-if)#no shutdown
R-1(config-if)#description Link to Revenue LAN
R-1(config-if)#exit

R-1(config)#interface s0/1/0
R-1(config-if)#ip address 209.165.201.2 255.255.255.252
R-1(config-if)#no shutdown
R-1(config-if)#description Link to Internet
R-1(config-if)#exit

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

Part 2: Basic Switch Configuration

Step 1: Configure Remote Management Addressing

a. Configure SVI 99 on switch S-3 with IP addressing according to the Addressing Table.
b. The S-3 switch SVI should be reachable from other networks.

S-3(config)#interface vlan 99
S-3(config-if)#ip address 172.31.99.18 255.255.255.240
S-3(config-if)#no shutdown
S-3(config-if)#exit
S-3(config)#
S-3(config)#ip default-gateway 172.31.99.17
Step 2: Configure Secure Remote Access

On switch S-3, configure SSH as follows:

  • Username: admin 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
S-3(config)#ip domain-name acad.pt
S-3(config)#crypto key generate rsa
How many bits in the modulus [512]: 1024

S-3(config)#username admin privilege 15 secret C1sco123!
S-3(config)#enable secret C1sco123!
S-3(config)#line vty 0 15
S-3(config-line)#transport input ssh
S-3(config-line)#login local
S-3(config-line)#exit
S-3(config)#ip ssh version 2

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.

S-2(config)#interface range f0/5-6
S-2(config-if-range)#channel-group 3 mode active
S-2(config-if-range)#exit
Step 2: Configure Trunking on the EtherChannels

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

MULTI-1
MULTI-1(config)#interface port-channel 1
MULTI-1(config-if)#switchport mode trunk
MULTI-1(config-if)#switchport trunk allowed vlan 10,20,30
MULTI-1(config-if)#exit
MULTI-1(config)#
MULTI-1(config)#interface port-channel 2
MULTI-1(config-if)#switchport mode trunk
MULTI-1(config-if)#switchport trunk allowed vlan 10,20,30
MULTI-1(config-if)#exit
S-1
S-1(config)#interface port-channel 1
S-1(config-if)#switchport mode trunk
S-1(config-if)#switchport nonegotiate
S-1(config-if)#exit
S-1(config)#
S-1(config)#interface port-channel 3
S-1(config-if)#switchport mode trunk

S-1(config-if)#switchport nonegotiate
S-1(config-if)#exit
S-2
S-2(config)#interface port-channel 2
S-2(config-if)#switchport mode trunk
S-2(config-if)#switchport nonegotiate
S-2(config-if)#exit
S-2(config)#
S-2(config)#interface port-channel 3
S-2(config-if)#switchport mode trunk

S-2(config-if)#switchport nonegotiate
S-2(config-if)#exit

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

a. On the S-3 switch, configure the port that is connected to R-1 G0/0/0 as a static trunk.
b. Configure the NetAdmin VLAN as the native VLAN.
c. Disable DTP on the port.

S-3
S-3(config)#interface g0/1
S-3(config-if)#switchport mode trunk
S-3(config-if)#switchport nonegotiate
S-3(config-if)#switchport trunk native vlan 99
S-3(config-if)#switchport trunk allowed vlan 40,50,60,99
S-3(config-if)#exit

Part 5: Configure Inter-VLAN Routing

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

a. Configure Inter-VLAN routing on the MULTI-1 Layer 3 switch for all VLANs in the VLAN Table that are configured on MULTI-1.
b. Configure the switchport on MULTI-1 that is connected to R-1 with an IP address as shown in the Addressing Table.

MULTI-1
MULTI-1(config)#ip routing
MULTI-1(config)#interface g1/1/1
MULTI-1(config-if)#no switchport
MULTI-1(config-if)#ip address 172.31.0.2 255.255.255.0
Step 2: Configure router-on-a-stick inter-VLAN routing on a router.

a. Configure inter-VLAN routing on R-1 for all the VLANs that are configured on the S-3 switch. Use the information in the Addressing Table.
b. Be sure to configure descriptions of all interfaces.

R-1
R-1(config)#interface g0/0/1

R-1(config)#interface g0/0/1.60
R-1(config-subif)#description "Gateway for VLAN60"
R-1(config-subif)#encapsulation dot1q 60
R-1(config-subif)#ip address 172.31.60.1 255.255.255.0
R-1(config-subif)#exit
R-1(config)#interface g0/0/1.99
R-1(config-subif)#description "Gateway for VLAN99"
R-1(config-subif)#encapsulation dot1q 99 native
R-1(config-subif)#ip address 172.31.99.17 255.255.255.240
R-1(config-subif)#exit
Step 3: Configure default gateways on hosts.

a. Configure default gateway addresses on all hosts on the LANs.

Default gateway on Host 1 and Host 4172.31.10.1
Default gateway on Host 2 and Host 5172.31.20.1
Default gateway on Host 3 and Host 6172.31.30.1

Default gateway on Host 7172.31.40.1
Default gateway on Host 8172.31.50.1
Default gateway on Host 9172.31.60.1
Default gateway on Admin Host172.31.99.17


b. Verify connectivity between all hosts on both LANs with each other and the Web Server server.
c. Verify that a host can connect to the SVI of switch S-3 over SSH.
