QUESTION 142

clip_image004

 

Each of these vlans has one host each on its ports

SVI on vlan 1 – ip 192.168.1.11

 

Switch B

Ports 3, 4 connected to ports 3 and 4 on Switch A Port 15 connected to Port on Router.

Tasks to do:

 

1.         Use non proprietary mode of aggregation with Switch B being the initiator

Use LACP with B being in Active mode

 

2.         Use non proprietary trunking and no negotiation

Use switchport mode trunk and switchport trunk encapsulation dot1q

 

3.         Restrict only to the VLANs needed

Use either VTP pruning or allowed VLAN list. The preferred method is using allowed VLAN list

 

4.         SVI on VLAN 1 with some ip and subnet given

 

5.         Configure switch A so that nodes other side of Router C are accessible

On switch A the default gateway has to be configured.

 

6.         Make switch B the root

 

Correct answer:

SW-A: verify with show run if you need to create vlans 21-23 and verify trunk’s native vlan

QUESTION 143

Scenario:

You work for SWITCH.com. They have just added a new switch (SwitchB) to the existing network as shown in the topology diagram.

 

clip_image006

 

RouterA is currently configured correctly and is providing the routing function for devices on SwitchA and SwitchB. SwitchA is currently configured correctly, but will need to be modified to support the addition of SwitchB. SwitchB has a minimal configuration. You have been tasked with competing the configuration of SwitchA and SwitchB. SwitchA and SwitchB use Cisco as the enable password.

 

Configuration Requirements for SwitchA

The VTP and STP configuration modes on SwitchA should not be modified.

Ÿ   SwitchA needs to be the root switch for vlans 11, 12, 13, 21, 22 and 23. All other vlans should be left are their default values.

 

Configuration Requirements for SwitchB

Ÿ   Vlan 21, Name: Marketing, will support two servers attached to fa0/9 and fa0/10

Ÿ   Vlan 22, Name: Sales, will support two servers attached to fa0/13 and fa0/14

Ÿ   Vlan 23, Name: Engineering, will support two servers attached to fa0/15 and fa0/16

Ÿ   Access ports that connect to server should transition immediately transition to forwarding state upon detecting the connection of a device.

Ÿ   SwitchB VTP mode needs to be the same as SwitchA.

Ÿ   SwitchB must operate in the same spanning tree mode as SwitchA

Ÿ   No routing is to be configured on SwitchB

Ÿ   Only the SVI vlan 1 is to be configured and it is to use address 192.168.1.11/24

 

Inter-switch Connectivity Configuration Requirements:

 

Ÿ  For operational and security reasons trunking should be unconditional and Vlans 1, 21, 22 and 23 should tagged when traversing the trunk link.

Ÿ  The two trunks between SwitchA and SwitchB need to be configured in a mode that allows for the maximum use of their bandwidth for all vlans. This mode should be done with a non- proprietary protocol, with SwitchA controlling activation.

Ÿ  Propagation of unnecessary broadcasts should be limited using manual pruning on this trunk link.

 

Correct answer:

SwitchB

SwitchB# conf t

 

Create vlan:

SwitchB(config)# vlan 21

SwitchB(config-vlan)# name Marketing

SwitchB(config-vlan)# vlan 22

SwitchB(config-vlan)# name Sales

SwitchB(config-vlan)# vlan 23

SwitchB(config-vlan)# name Engineering

QUESTION 144

You have been tasked with configuring multilayer SwitchC, which has a partial configuration and has been attached to RouterC as shown in the topology diagram.

 

clip_image008

 

HOST 1:

clip_image010

 

HOST 2:

clip_image012

 

You need to configure SwitchC so that Hosts H1 and H2 can successful ping the server S1. Also SwitchC needs to be able to ping server S1.

 

Due to administrative restrictions and requirements you should not add/delete vlans, changes VLAN port assignments or create trunk links Company policies forbid the use of static or default routing All routes must be learned via EIGRP 65010 routing protocol.

 

You do not have access to RouteC, RouterC is correctly configured. No trunking has been configured on RouterC.

 

Routed interfaces should use the lowest host on a subnet when possible. The following subnets are available to implement this solution:

 

Ÿ   172.16.1.0/24

Ÿ   192.168.3.32/27

Ÿ   192.168.3.64/27

 

Hosts H1 and H2 are configured with the correct IP address and default gateway. SwitchC uses Cisco as the enable password.

 

Routing must only be enabled for the specific subnets shown in the diagram.

 

Correct Answer:

On switch C:

SwitchC> enable

SwitchC# conf t

 

SwitchC(config)# int gi 0/1

SwitchC(config-if)# no switchport

SwitchC(config-if)# ip address 172.16.1.1 255.255.255.0

SwitchC(config-if)# no shutdown

SwitchC(config-if)# exit

 

SwitchC(config)# int vlan 2

SwitchC(config-if)# ip address 192.168.3.33 255.255.255.224

SwitchC(config-if)# no shutdown

SwitchC(config-if)# exit

 

SwitchC(config-if)# int vlan 3

SwitchC(config-if)# ip address 192.168.3.65 255.255.255.224

SwitchC(config-if)# no shutdown

SwitchC(config-if)# exit

 

SwitchC(config)# ip routing

SwitchC(config-router)# router eigrp 65010

SwitchC(config-router)# network 172.16.1.0 0.0.0.255

SwitchC(config-router)# network 192.168.3.32 0.0.0.31

SwitchC(config-router)# network 192.168.3.64 0.0.0.31

SwitchC(config-router)# no auto-summary

SwitchC(config-router)# end

SwitchC# copy running-config startup-config
