Free Router Simulators (copy from 9tut)

f you are going to take a networking exam like CCNA, CCNP... it is better to practice with real routers. But when the budget is not big enough or you can only access to hardware in your school then router simulator softwares are the best things you can get for free. The followings are a number of free and popular router simulators you can download and practice with:

Packet Tracer - Packet Tracer 5.0 is the latest version of Cisco Networking Academy’s comprehensive networking technology teaching and learning software. Innovative features of Packet Tracer 5.0, including powerful simulation, visualization, authoring, assessment, and collaboration capabilities, will help students and teachers collaborate, solve problems, and learn concepts in an engaging and dynamic social environment. Moreover, it's totally free! You can download this software but you need to register first or you can find a mirror download with google (with keyword "download packet tracer")

CCNA VTP SIM Question

(Updated from lastest CCNA exam on 09-10-2008)

Question:

This task requires you to use the CLI of Sw-AC3 to answer five multiple-choice questions. This does not require any configuration.
To answer the multiple-choice questions, click on the numbered boxes in the right panel.
There are five multiple-choice questions with this task. Be sure to answer all five questions before leaving this item.

Notice: All the images in this VTP LAB are used for demonstration only, 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.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, use the show mac-address-table command. It shows the learned MAC addresses and their associated interfaces. After entering this command, you will see a MAC address table like this:

From this table we can figure out that the MAC address 0010.5a0c.ffba is associated with interface Fa0/8

Question 2:

What ports on Sw-AC3 are operating has trunks (choose two)?

a) Fa0/1
b) Fa0/3
c) Fa0/4
d) Fa0/6
e) Fa0/9
f) Fa0/12

Answer: Fa0/9 and Fa0/12

Explanation: Use the show interface trunk command to determine the trunking status of a link and VLAN status. This command lists port, its mode, encapsulation and whether it is trunking. 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: 2611

Explanation: VLAN-R1 is the router directly connected to Sw-Ac3 switch, so we can use the show cdp neighbors command to see:

1. Neighbor Device ID : The name of the neighbor device;
2. Local Interface : The interface to which this neighbor is heard
3. Capability: Capability of this neighboring device - R for router, S for switch, H for Host etc.
4. Platform: Which type of device the neighbor is
5. Port ID: The interface of the remote neighbor you receive CDP information
6. Holdtime: Decremental hold time in seconds

Sample output of show cdp neighbors command:

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

Notice that if you see all of the interface roles are Desg (designated) then you can confirm Sw-Ac3 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, we notice that the root port on Sw-Ac3 switch is FastEthernet0/12, so we have to figure out which switch is associated with this port -> it is the root bridge. 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. 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?

Answer: 192.168.44.254

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 Fa0/0.44 with IP address 192.168.44.254/24

Therefore the default gateway of the host should be 192.168.44.254

Question 6: From which switch did Sw-Ac3 receive VLAN information ?

Answer: Sw-AC2

Explanation: to view the VTP configuration information, use the show vtp status command

So we knew Sw-Ac3 received VLAN information from 163.5.8.3 (notice:the IP address may be different). Finally we use the show cdp neighbors detail to find out who 163.5.8.3 is:

There are still some questions for the VTP SIM, I will update them soon!
