free VLAN routing and switching practice exam for Cisco CCNA certification

The Cisco CCNA certification requires that you are completely familiar with VLANs. CCNA certification practice exams are a great way to prepare for the Cisco CCNA certification and for jobs that will require you to install, maintain, and configure VLAN routing and switching on Cisco routers and switches. This free practice exam will help you to know the Cisco VLAN routing and switching well enough that you can productively apply your Cisco VLAN routing and switching knowledge to any network. The Cisco CCNA certification is an entry level certification which will equip you for the type of work that requires extensive use of VLAN routing and switching.

What is the chief benefit of using VLANs.

1. The ethernet distance constraints are lifted because of switches.
2. You are no longer confined to defining workgroups by physical location or geography.
3. Trunking can used to link VLANs together.
4. You can create multiple smaller broadcast domains.

Very large networks created because of switching means that server centric security leaves client PC's openly available and visible to all users. This leads to excessive broadcast traffic and the resulting replies. These are all symptoms of:

1. A large flat layer two network design.
2. A large hierarchical network design.
3. Not enough routers.
4. Poor network design.

Which of the following is not an issue that is addressed by using switched VLANs?

1. Security.
2. Broadcast control.
3. Flexibility and scalability.
4. Ease of administration.

Devices connected to a switch configured for VLANs will:
 

1. not receive broadcasts from devices outside of their VLAN
2. receive broadcasts from devices outside of their VLAN

Using VLANs on a network means that:

1. Any user can capture any data packet traversing the internetwork.
2. Any user can join any workgroup on the domain by plugging into any port.
3. Any user cannot join any workgroup on the domain by plugging into any port.

The ability to add more switches to the internetwork is an example of:

1. security.
2. flexibility and scalability.
3. broadcast control.
4. ease of administration.

True or false? The use of VLANs on switches eliminates the need for routers.
 

1. True.
2. False.

Which is the most secure type of VLAN?

1. Dynamic.
2. Static.

Which VLAN type is more work to maintain?

1. Static.
2. Dynamic.

Communication between devices on different VLANs must pass thru a router on which type of link?

1. Access Link.
2. Trunk Link.

Communication between devices on different VLANs do not need to pass thru a router on which type of link?
 

1. Access Link.
2. Trunk Link.

Which defines frame tagging?
 

1. A "type of service" flag that marks a piece of data telling the switches where to send it.
2. The process of assigning an identification given to a Layer two piece of data that is not removed until it reaches a device that terminates at the destination point.
3. The process of assigning a user defined identification given to a Layer two piece of data that is not removed until it reaches a device that terminates at the destination point.
4. A "quality of service" flag that marks a piece of data telling the switches where to send it.

Which VLAN identification method is proprietary to Cisco devices.

1. ISL.
2. 802.1q.
3. LANE.
4. 802.10.

Which defines how inter switch link places vlan ids on ethernet frames?

 
1. It inserts a field in the ethernet frame that is used to identify or "carry" the vlan id. 
2. It sets the vlan id in the ethernet frame header with a two byte value for ethernet frames and it uses the frame trailer in token ring frames.
3. It encapsulates the frame within a frame of its own that carries the vlan id.
4. It uses the SAID field in the frame header to identify the vlan.

Why would you be required to use 802.1q on a Cisco device?
 

1. Your network uses devices that cannot manage "giant" frames or frames over 1518 bytes in length.
2. A network server is required to be a member of multiple vlans at the same time.
3. Traffic destined for a server would otherwise need to go through a router in order for different vlans to communicate.
4. The Cisco device is required to communicate with equipment from other vendors.

Which port speed does not work with trunking lines?

1. 10mbps.
2. 100mbps.
3. 1000mbps.

If trunking is not configured between two switches, what information will traverse the links between the two switches?

1. Only vlan 1 information.
2. Only vlan 1005 information.
3. Any similar vlan information common to the two switches.
4. Frame forwarding to any layer three hosts.

Trunk link information is carried between switches using what protocol?
 

1. VTP Virtual Trunking Protocol.
2. DTP Dynamic Trunking Protocol.
3. ISL Inter-Switch Link.

To enable communication between only 2 or 3 VLANs, it is possible to put each ethernet interface on a router on a different VLAN. What is the alternative method of communicating between VLANs using a router?

1. You can't do that on a router, you need an rsm on the core switch.
2. install more ethernet interfaces on the router.
3. Using ISL routing on a router with ethernet interfaces.
4. Using ISL routing on a router with fastethernet interfaces.

Which is the least expensive router that supports ISL routing?

 
1. 2500 series.
2. 2600 series.
3. 3600 series.
4. 1700 series.

Which statement accurately defines the role or purpose of the VTP (Virtual Trunking Protocol)?

1. To allow network administrators to add, delete, or modify VLANS.
2. The VTP will permit trunking of VLANs across disparate networks.
3. The VTP can manage and maintain consistency of VLANS across a switched internetwork.

True or False? A VTP server is required to manage switches belonging to multiple VLANs.

1. False.
2. True.

Which statement correctly describes transparent mode operation?

1. The switch does not participate in VTP domains but will passively accept VTP updates from a VTP server. It can still keep its own locally significant VLAN database.
2. The switch receives info from the VTP servers and sends and receives updates, but does not make any changes. It only accepts new VLAN info propogated from the VTP servers
3. The switch receives info from the VTP servers and sends and receives updates. It only makes changes for VLANs on its own ports. It accepts new VLAN info from the VTP server.
4. The switch does not participate in VTP domains but will pass along VTP advertisments through connected trunk lines. It can still keep its own locally significant VLAN database.

Which statement accurately describes a switch in VTP client mode of operation?

1. The switch does not participate in VTP domains but will passively accept VTP updates from a VTP server. It can still keep its own locally significant VLAN database.
2. The switch receives info from the VTP servers and sends and receives updates, but does not make any changes. It only accepts new VLAN info propogated  from the VTP servers
3. The switch receives info from the VTP servers and sends and receives updates. It only makes changes for VLANs on its own ports. It accepts new VLAN info from the VTP server.
4. The switch does not participate in VTP domains but will pass along VTP advertisments through connected trunk lines. It can still keep its own locally significant VLAN database.

VLAN trunking protocol advertisements are only accepted by a client switch when:

1. The revision number is higher than the revision number last accepted.
2. The revision number is lower than the revision number last accepted.
3. The switch holds VLAN information in NVRAM matching that being advertised by the server.
4. The switch and the server have matching VTP domain passwords.
