Question:
I am still not sure about the question but we need to configure the Multilayer Switch so that PCs from VLAN 2 and VLAN 3 can communicate with the Server.
Answer and Explanation
Question:
Acme is a small export company that has an existing enterprise network comprised of 5 switches;
CORE,DSW1,DSW2,ASW1 and ASW2. The topology diagram indicates their desired pre-VLAN spanning tree mapping.
Previous configuration attempts have resulted in the following issues:
– CORE should be the root bridge for VLAN 20; however, DSW1 is currently the root bridge for VLAN 20.
– Traffic for VLAN 30 should be forwarding over the gig 1/0/6 trunk port between DSW1 and DSW2. However VLAN 30 is currently using gig 1/0/5.
– Traffic for VLAN 40 should be forwarding over the gig 1/0/5 trunk port between DSW1 and DSW2. However VLAN 40 is currently using gig 1/0/6.
You have been tasked with isolating the cause of these issuer and implementing the appropriate solutions. You task is complicated by the fact that you only have full access to DSW1, with isolating the cause of these issues and implementing the appropriate solutions. Your task is complicated by the fact that you only have full access to DSW1, with the enable secret password cisco. Only limited show command access is provided on CORE, and DSW2 using the enable 2 level with a password of acme. No configuration changes will be possible on these routers. No access is provided to ASW1 or ASW2.

Question:
The headquarter offices for a book retailer are enhancing their wiring closets with Layer3 switches. The new distribution-layer switch has been installed and a new access-layer switch cabled to it. Your task is to configure VTP to share VLAN information from the distribution-layer switch to the access-layer devices. Then, it is necessary to configure interVLAN routing on the distribution layer switch to route traffic between the different VLANs that are configured on the access-layer switches; however, it is not necessary for you to make the specific VLAN port assignments on the access-layer switches. Also, because VLAN database mode is being deprecated by Cisco, all VLAN and VTP configurations are to be completed in the global configuration mode. Please reference the following table for the VTP and VLAN information to be configured:
Requirements:
| VTP Domain name | cisco | |
| VLAN Ids | 20 | 21 |
| IP Addresses | 172.16.71.1/24 | 172.16.132.1/24 |
These are your specific tasks:
1. Configure the VTP information with the distribution layer switch as the VTP server
2. Configure the VTP information with the access layer switch as a VTP client
3. Configure VLANs on the distribution layer switch
4. Configure inter-VLAN routing on the distribution layer switch
5. Specific VLAN port assignments will be made as users are added to the access layer switches in the future.
6. All VLANs and VTP configurations are to completed in the global configuration. To configure the switch click on the host icon that is connected to the switch be way of a serial console cable.

Question:
The headquarter office for a cement manufacturer is installing a temporary Catalyst 3550 in an IDF to connect 24 additional users. To prevent network corruption, it is important to have the correct configuration prior to connecting to the production network. It will be necessary to ensure that the switch does not participate in VTP but forwards VTP advertisements that are received on trunk ports.
Because of errors that have been experienced on office computers, all nontrunking interfaces should transition immediately to the forwarding state of Spanning tree. Also, configure the user ports (all FastEthernet ports) so that the ports are permanently nontrunking.
Requirements:
You will configure FastEthernet ports 0/12 through 0/24 for users who belong to VLAN 20. Also, all VLAN and VTP configurations are to be completed in global configuration mode as VLAN database mode is being deprecated by Cisco. You are required to accomplish the following tasks:
1. Ensure the switch does not participate in VTP but forwards VTP advertisements received on trunk ports.
2. Ensure all non-trunking interfaces (Fa0/1 to Fa0/24) transition immediately to the forwarding state of Spanning-Tree.
3. Ensure all FastEthernet interfaces are in a permanent non-trunking mode.
4. Place FastEthernet interfaces 0/12 through 0/24 in VLAN 20.

Question:
Acme is a small shipping company that has an existing enterprise network comprised of 2 switches;DSW1 and ASW1. The topology diagram indicates their layer 2 mapping. VLAN 40 is a new VLAN that will be used to provide the shipping personnel access to the server. For security reasons, it is necessary to restrict access to VLAN 20 in the following manner:
– Users connecting to ASW1’s port must be authenticate before they are given access to the network. Authentication is to be done via a Radius server:
– Radius server host: 172.120.39.46
– Radius key: rad123
– Authentication should be implemented as close to the host device possible.
– Devices on VLAN 20 are restricted to in the address range of 172.120.40.0/24.
– Packets from devices in the address range of 172.120.40.0/24 should be passed on VLAN 20.
– Packets from devices in any other address range should be dropped on VLAN 20.
– Filtering should be implemented as close to the server farm as possible.
The Radius server and application servers will be installed at a future date. You have been tasked with implementing the above access control as a pre-condition to installing the servers. You must use the available IOS switch features.

Question
Online Incorporated is an internet game provide. The game service network had recently added an additional switch block with multiple VLANs configured. Unfortunately, system administrators neglected to document the spanning-tree topology during configuration. For baseline purpose, you will be required to identify the spanning-tree topology for the switch block. Using the output of “show spanning-tree” command on switch SW-C and the provided physical topology, answer the following questions:
The output of “show spanning-tree” command on SW-C:
Question:
- DSW1( Distribute switch 1) is the primary device for Vlan 101, 102, 105
– DSW2 ( Distribute switch 2) is the primary device for Vlan 103 and 104
Here you will find answers to Drap and Drop questions
Question 1:
Place the DTP mode with its correct description:
Answer:
1) Trunk: Set the switch port to trunk mode and negotiate to become a trunk.
2) Nonegotiate: Specify that the DTP packets are not sent out of this interface.
3) Access: Set a switch port to permanent nontrunking mode.
4) Dynamic Auto: Set the switch port to respond, but not actively send DTP frames.
5) Dynamic Desirable: Make the interface actively attempt to convert the link to a trunk link. (This means the interface is ready to autonegotiate trunking encapsulation and form a trunk link (using DTP) with a neighbor port in desirable, auto, or on mode.)
Explanation:
Dynamic Trunking Protocol (DTP) is the Cisco-proprietary that actively attempts to negotiate a trunk link between two switches. Below is the switchport modes (or DTP modes) for easy reference:
| Mode | Function |
| Dynamic Auto | Creates the trunk based on the DTP request from the neighboring switch. |
| Dynamic Desirable | Communicates to the neighboring switch via DTP that the interface would like to become a trunk if the neighboring switch interface is able to become a trunk. |
| Trunk | Automatically enables trunking regardless of the state of the neighboring switch and regardless of any DTP requests sent from the neighboring switch. |
| Access | Trunking is not allowed on this port regardless of the state of the neighboring switch interface and regardless of any DTP requests sent from the neighboring switch. |
| Nonegotiate | Prevents the interface from generating DTP frames. This command can be used only when the interface switchport mode is access or trunk. You must manually configure the neighboring interface as a trunk interface to establish a trunk link. |
Question 2:
This is a drag and drop question which is about the correct sequence of steps that a wireless client takes during the process of association with an access point (AP). Drag the items to the proper locations.
Answer:
Explanation:
Any wireless client attempting to use the wireless network must first arrange a membership with the AP. Membership with the AP is called an association. The client must send an association request message, and the AP grants or denies the request by sending an association reply message. Once associated, all communications to and from the client must pass through the AP. Clients associate with access points as follows:
1) The client sends a probe request.
2) The AP sends a probe response.
3) The client initiates an association to an AP. Authentication and any other security information is sent to the AP.
4) The AP accepts the association.
5) The AP adds the client’s MAC address to its association table.
Question 3:
Drag and drop question. Drag the items to the proper locations.
Answer:
1) Listening: sends and receives BPDUs to determine root, but does not update the MAC address table.
2) Disabled: does not participate in frame forwarding or in STP.
3) Blocking: does not participate in frame forwarding.
4) Fowarding: sends and receives data frames.
5) Learning: populates the MAC address table, but will not forward user data.
Notice: A port begins its life in a Disabled state, moving through several passive states and, finally, into an active state if allowed to forward traffic.
