CCNA Access List Sim 2
Question A network associate is adding security to the configuration of the Corp1 router. The user on host C should be able to use a web browser to access financial information from the Finance Web Server. No other hosts from the LAN nor the Core should be able to use a web browser to access this server. Since there are multiple resources for the corporation at this location including other resources on the Finance Web Server, all other traffic should be allowed. The task is to create and apply an access-list with no more than three statements that will allow ONLY host C web access to the Finance Web Server. No other hosts will have web access to the Finance Web Server. All other traffic is permitted. Access to the router CLI can be gained by clicking on the appropriate host. All passwords have been temporarily set to “cisco”. The Core connection uses an IP address of 198.18.196.65 The computers in the Hosts LAN have been assigned addresses of 192.168.33.1 – 192.168.33.254 Host A 192.168.33.1 Host B 192.168.33.2 Host C 192.168.33.3 Host D 192.168.33.4 The servers in the Server LAN have been assigned addresses of 172.22.242.17 – 172.22.242.30 The Finance Web Server is assigned an IP address of 172.22.242.23.

168.30 (.22.17 – 172.22.22.242. Use the “show running-config” command to check which interface has the IP address of 172.30 so we can guess the interface connected to them has an IP address of 172.23 via web (port 80) Corp1(config)#access-list 100 permit tcp host 192.168.242. The Server LAN network has been assigned addresses of 172. Corp1#configure terminal Our access-list needs to allow host C – 192.22.33.23 eq 80 All other traffic is permitted Corp1(config)#access-list 100 permit ip any any Apply this access-list to Fa0/1 interface (outbound direction) . Corp1#show running-config We learn that interface FastEthernet0/1 is the interface connected to Server LAN network.242.Answer and Explanation Corp1>enable (you may enter “cisco” as it passwords here) We should create an access-list and apply it to the interface which is connected to the Server LAN because it can filter out traffic from both Sw-2 and Core networks.22.33.242.30 is the number shown in the figure).30.22.23 eq 80 Deny other hosts access to the Finance Web Server via web Corp1(config)#access-list 100 deny tcp any host 172.3 to the Finance Web Server 172.242.242. It is the interface we will apply our access-list (for outbound direction).3 host 172.242.22.

In the address box type http://172. If your configuration is correct then you can access it. SMTP… then other hosts can access it. To answer the multiple-choice questions. In the real exam.242.Corp1(config)#interface fa0/1 Corp1(config-if)#ip access-group 100 out Notice: We have to apply the access-list to Fa0/1 interface (not Fa0/0 interface) so that the access-list can filter traffic coming from the Core network.22. .23 to check if you are allowed to access Finance Web Server or not. just click on host C and open its web browser. too. save the configuration Corp1(config-if)#end Corp1#copy running-config startup-config (This configuration only prevents hosts from accessing Finance Web Server via web but if this server supports other traffic – like FTP. Click on other hosts (A.) Notice: In the real exam. you might be asked to allow other host (A. Finally. CCNA VTP SIM Question Question This task requires you to use the CLI of Sw-AC3 to answer five multiple-choice questions. B or D) to access the Finance Web Server so please read the requirement carefully. B and D) and check to make sure you can’t access Finance Web Server from these hosts. This does not require any configuration. click on the numbered boxes in the right panel.

use the show mac-address-table command. After entering this command. It shows the learned MAC addresses and their associated interfaces. Be sure to answer all five questions before leaving this item. you will see a MAC address table like this: From this table we can figure out that the MAC address 0010. you will see slightly different images in the real CCNA exam Question 1 What interface did Sw-AC3 associate with source MAC address 0010.5a0c.There are five multiple-choice questions with this task. Notice: All the images in this VTP LAB are used for demonstration only.5a0c.ffba is associated with interface Fa0/8 Question 2 What ports on Sw-AC3 are operating has trunks (choose three)? a) Fa0/1 b) Fa0/3 c) Fa0/4 d) Fa0/6 e) Fa0/9 f) Fa0/12 .ffba ? a) Fa0/1 b) Fa0/3 c) Fa0/6 d) Fa0/8 e) Fa0/9 f) Fa0/12 Answer: Fa 0/8 Explanation: to find out which interface associated with a given MAC address.

Fa0/9 and Fa0/12 Explanation: Use the show interface trunk command to determine the trunking status of a link and VLAN status. H for Host etc. so we can use the show cdp neighbors command to see: 1.Answer: Fa0/3. The image below shows how it works: (This image is used for demonstration only) Question 3 What kind of router is VLAN-R1? a) 1720 b) 1841 c) 2611 d) 2620 Answer: 2620 Explanation: VLAN-R1 is the router directly connected to Sw-Ac3 switch. its mode. 4. S for switch. Platform: Which type of device the neighbor is 5. Holdtime: Decremental hold time in seconds Sample output of show cdp neighbors command: . Capability: Capability of this neighboring device – R for router. Neighbor Device ID : The name of the neighbor device. This command lists port. Local Interface : The interface to which this neighbor is heard 3. encapsulation and whether it is trunking. 2. Port ID: The interface of the remote neighbor you receive CDP information 6.

One thing I want to notice you is “Local Intrfce” in the image above refers to the local interface on the device you are running the “show cdp neighbors” command Question 4 Which switch is the root bridge for VLAN 1? Answer: Sw-DS1 Explanation: First we use the show spanning-tree vlan 1 to view the spanning-tree information of VLAN 1 From the “Cost 19″. You can verify it with the show cdp neighbors command: The “Local Intrfce” column refers to the interface on the switch running “show cdp neighbors” command. we learn that the root switch is directly connected to the Sw-Ac3 switch over a 100Mbps Ethernet link Notice that if you see all of the interface roles are Desg (designated) then you can confirm SwAc3 switch is the root bridge for this VLAN (VLAN 1). If you see there is at least one Root port in the interface roles then you can confirm Sw-Ac3 is not the root bridge because root bridge does not have root port. In this case. Sw-DS1 is associated with interface FastEthernet0/12 -> Sw-DS1 is the root bridge Question 5 What address should be configured as the default-gateway for the host connected to interface fa 0/4 of SW-Ac3? . we notice that the root port on Sw-Ac3 switch is FastEthernet0/12. In this case. so we have to figure out which switch is associated with this port -> it is the root bridge.

254/24 Therefore the default gateway of the host should be 192. use the show vtp status command .44 with IP address 192.254 Question 6 From which switch did Sw-Ac3 receive VLAN information ? Answer: Sw-AC2 Explanation: to view the VTP configuration information.168.44.254 Explanation: First we have to identify which VLAN interface Fa0/4 belongs to by the show vlan command From the exhibit we know that VLAN 44 is configured on router using sub-interface Fa0/0.168.168.44.44.Answer: 192.

5. Production and no-where will be removed from existing switches Answer and Explanation: First we should view the VTP configuration of switch Sw-Ac3 by using the show vtp status command on Sw-Ac3 . Servers. Management. Production and no-where will replace the VLANs on SwX D – The VLANs Servers.8. admin.So we knew Sw-Ac3 received VLAN information from 163.3 (notice:the IP address may be different). Management. Management. and no-where VLANs C – The VLANs Servers. SwX was taken out of the production network for maintenance.5.3 is: Question 7 Refer to the exibit. Production. It will be reconnected to the Fa 0/16 port of Sw-Ac3. What happens to the network when it is reconnected and a trunk exists between the two switches? A – All VLANs except the default VLAN win be removed from all switches B – All existing switches will have the students. faculty. Finally we use the show cdp neighbors detail to find out who 163.8.

Therefore SwX will replace vlan information on other switches with its own information. Also. the answer should be “C – The VLANs Servers. Management.In particular. Production and no-where will be removed from existing switches Please notice that in the real CCNA exam you may see a different configuration revision of SwAc3 or of SwX. which is greater than that of Sw-Ac3 switch. In general. . Management. some recent comments have said that the new switch’s VTP Operating Mode is Server but the answer is still the same. Production and no-where will replace the VLANs on SwX”. and both of them have same VTP Domain Name called “home-office”.Notice that its configuration revision number is 5 and VTP Domain Name is home-office Next. if the revision number of SwX is lower than that of Sw-Ac3. which switch has a higher revision number it will become the updater and other switches will overwrite their current databases with the new information received from the updater (provided that they are on the same domain and that switch is not in transparent mode). from the exhibit we know that SwX has a revision number of 6. We should check vlan information of Sw-Ac3 switch with show vlan command So the correct answer is D – The VLANs Servers.

it means that there can be other ports besides Fa0/1. Fa0/3 and Fa0/12.8a47. we can figure out it will flood this frame to Fa0/1. except the port it received this frame (port Fa0/6). Please notice that the “show mac-address-table” command just lists information that was learned by the switch.e612 in this table. In this case.fd86 and destination mac-address 000a. You can use the show vlan command to see which ports belong to vlan 33 . Therefore from the output above.Question 8 Out of which ports will a frame be forwarded that has source mac-address 0010.5a0c.e612? (Choose three) A – Fa0/8 B – Fa0/3 C – Fa0/1 D – Fa0/12 Answer: B C D Explanation: First we check to see which ports the source mac-address and the destination mac-address belong to by using show mac-address-table command We notice that the source mac-address 0010. Fa0/3 and Fa0/12 belong to Vlan 33. the switch will flood to all ports of Vlan 33 and flood to all the trunk links.5a0c.fd86 is listed in the table and it belongs to Vlan 33 but we can’t find the destination mac-address 000a.8a47.

And we found other ports which belong to vlan 33.1. we can confirm the switch’s default gateway is VLAN-R1 router (with the IP address of 192. and in this case. So we have to find out who is the default gateway of this switch by using the show running-config command From the output. too. And “the interface: FastEthernet0/3″ tells us that the switch is connected to VLAN-R1 router through Fa0/3 port (Fa0/3 is the port on the switch).168. To verify our theory.1.0.2. it will forward the packet to its default gateway.168.5 (or any ip that is not on the same subnet) what will be the destination MAC address? Answer and Explanation: Because the destination address is not on the same subnet with the switch. Our switch will flood the frame to these ports. the VLAN-R1 router. . we can easily guess that its default gateway should be a layer 3 device like a router. we notice that its default-gateway is 192. And we can check which trunk ports will receive this frame by the show interface trunk command -> Port Fa0/9 will also receive this frame! Question 9 If one of the host connected to Sw-AC3 wants to send something for the ip 190. they are Fa0/2.254. In fact.254). Fa0/5 and Fa0/7. use the show cdp neighbor detail command and focus on the description of VLAN-R1 router From this output.

Access to the router CLI can be gained by clicking on the appropriate host. All passwords on all routers are cisco. IP addresses are listed in the chart below. The task is to identify the fault(s) and correct the router configuration to provide full connectivity between the routers.8360. no routing updates are being exchanged between R3 and the new location. All other inter connectivity and Internet access for the existing locations of the company are working properly.b7e9.Finally we just need to use the show mac-address-table command to find out which MAC address is associated with this interface (Notice that in the real CCNA exam the MAC address or port may be different) And we find out the corresponding MAC address is 000a. . Although there are some entries of port Fa0/3 with different Vlans but they have the same MAC address CCNA EIGRP LAB Question Question After adding R3 router.

18.168.33 Fa0/0: 192.60.168.60.129 Fa0/1: 192.26 Answer and explanation We should check the configuration of the new added router first because it does not function properly while others work well.168.168.6 Fa0/1: 192.168.65 Fa0/1: 192.81 S0/1: 192.60. enter the show running-config command .168.60.60.36.113 S0/1: 192.145 Fa1/0: 192.77.25 S0/0: 192.168.R1 R2 Fa0/0: 192.168.60.34 Fa0/0: 192.60.168.60.77.97 S1/0: 198.0.168. From the command line interface of R3 router.168.14 R3 R4 Fa0/0: 192.

168. You should check again with ping command from router R3 to other routers! . (You should check the AS numbers on other routers for sure) To solve this problem.77.0 R3(config-router)#network 192.168.0 R3(config-router)#no auto-summary R3(config-router)#end R3#copy running-config startup-config Check R1 router with the show running-config command: Notice that it is missing a definition to the network R3. Therefore we have to add it so that it can recognize R3 router R1>enable (you have to enter cisco as its password here) R1#configure terminal R1(config)#router eigrp 212 R1(config-router)#network 192. we know that this router was wrongly configured with an autonomous number (AS) of 22. we simply re-configure router R3 with the following commands: R3>enable (you have to enter cisco as its password here) R3#configure terminal R3(config)#no router eigrp 22 R3(config)#router eigrp 212 R3(config-router)#network 192.168.60.77. When the AS numbers among routers are mismatched.0 R1(config-router)#end R1#copy running-config startup-config Now the whole network will work well.From the output above. no adjacency is formed.
