Welcome to the Virtual Local Area Network Trivia Quiz. A virtual area network is essentially a LAN that is on top of a physical LAN. This quiz will test out just how much you know when it comes to positioning a VLAN and how effective it will be. Do give it a try and get to learn some new things too. All the best!
Questions and Answers
- 1.
How many untagged VLAN's can a switch port be a member of
- A.
1
- B.
Unlimited
- C.
4096
- D.
Dependent on the capacity of the switch
Correct Answer
A. 1Explanation
A switch port can only be a member of one untagged VLAN at a time. This means that the port will forward traffic for that VLAN without any VLAN tagging. If the port needs to be a member of multiple VLANs, it can be configured as a tagged port, where VLAN tagging is used to differentiate between the different VLANs. However, for untagged VLANs, the switch port can only be a member of one VLAN.Rate this question:

On a switch , port 1 and port 2 are configured as members of vlan 2 and vlan 3 respectively. Which of the following is true
- A.
Broadcast traffic initiated on port 1 will not be available on port 2
- B.
Unicast traffic initiated on port 1 will be available on port 2
- C.
Broadcast traffic initiated on port 1 will be available on port 2 if a router is configured.
- D.
All of the above
Correct Answer
A. Broadcast traffic initiated on port 1 will not be available on port 2Explanation
When port 1 and port 2 are configured as members of different VLANs (VLAN 2 and VLAN 3 respectively), they are isolated from each other. Broadcast traffic initiated on port 1 will only be available to other members of VLAN 2 and will not be forwarded to port 2. Therefore, the statement "Broadcast traffic initiated on port 1 will not be available on port 2" is true.Rate this question:

What additional device is required for communication between two PC's on same VLAN
- A.
Router
- B.
Layer 3 switch
- C.
Default gateway
- D.
No additional device is required
Correct Answer
D. No additional device is requiredExplanation
No additional device is required because VLANs are virtual LANs that can be created within a switch. PCs within the same VLAN can communicate with each other without the need for any additional device. VLANs separate the network into smaller broadcast domains, allowing for better network performance and security.Rate this question:

An IP address is required for TCP communication between two computers residing on the same VLAN.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In TCP communication, an IP address is required for two computers to establish a connection and exchange data. The IP address is used to uniquely identify each computer on the network, allowing them to locate and communicate with each other. In the given scenario, since the two computers are residing on the same VLAN (Virtual Local Area Network), they still require an IP address to establish TCP communication. Therefore, the statement is true.Rate this question:

How many VLAN's can be configured on a switch
- A.
4096
- B.
2048
- C.
Number of ports on the switch = Number of VLAN's
- D.
Based on the switch design
Correct Answer
D. Based on the switch designExplanation
The number of VLAN's that can be configured on a switch is based on the switch design. Different switches have different limitations and capabilities when it comes to VLAN configuration. Some switches may support a maximum of 4096 VLAN's, while others may support fewer. Therefore, the number of VLAN's that can be configured on a switch depends on how the switch is designed and its specific capabilities.Rate this question:

Which feature can be used to carry all VLAN traffic on one link from a switch to a router
- A.
Trunking
- B.
Pruning
- C.
LACP
- D.
None of the above
Correct Answer
A. TrunkingExplanation
Trunking is a feature that allows for the transmission of multiple VLANs over a single link between a switch and a router. By using trunking, the switch can tag each VLAN traffic with a specific identifier, allowing the router to differentiate and process the traffic accordingly. This helps to optimize network efficiency and reduce the number of physical connections needed between the switch and the router.Rate this question:

Which of the following would be unavailable in a 802.1q tagged frame
- A.
Source mac-address
- B.
Destination mac-address
- C.
802.1q tag
- D.
None of the above
Correct Answer
D. None of the aboveExplanation
In a 802.1q tagged frame, all of the mentioned elements would be available. The source mac-address and destination mac-address are essential components of a frame, and the 802.1q tag is used to identify the VLAN to which the frame belongs. Therefore, none of the above options would be unavailable in a 802.1q tagged frame.Rate this question:

PC1 and PC2 are connected to port 1 and port 2 of a switch. Port 1 and Port 2 are members of VLAN 1 and VLAN 2 respectively. A router is also configured, with VLAN 1 IP address as 192.168.1.1/24 and VLAN 2 IP address as 192.168.2.1/24 and connected to the switch with trunking enabled. What should be the default gateway on PC1 for it to access PC2.
- A.
192.168.2.1
- B.
192.168.1.1
- C.
A default gateway need not be explicitly configured since a router is available
- D.
Management IP address of vlan 1
Correct Answer
B. 192.168.1.1Explanation
The default gateway on PC1 should be set to 192.168.1.1 in order to access PC2. This is because PC1 and PC2 are on different VLANs, and the router is connected to the switch with trunking enabled. The router has separate IP addresses configured for each VLAN, with 192.168.1.1 for VLAN 1 and 192.168.2.1 for VLAN 2. Setting the default gateway on PC1 to 192.168.1.1 will allow it to reach the router and access PC2 on VLAN 2.Rate this question:

Which of the following are true
- A.
VLAN's needs to be configured with IP addresses
- B.
VLANs need not have an IP address
- C.
VLAN's does not allow broadcast traffic from one VLAN to another
- D.
VLAN's can be configure on Hubs
Correct Answer(s)
B. VLANs need not have an IP address
C. VLAN's does not allow broadcast traffic from one VLAN to anotherExplanation
VLANs need not have an IP address because VLANs are primarily used for segmenting a network into smaller, isolated virtual networks. They operate at the data link layer (Layer 2) of the OSI model and do not require IP addresses to function.
VLANs do not allow broadcast traffic from one VLAN to another because they create separate broadcast domains. Broadcast traffic is contained within each VLAN, preventing it from crossing over to other VLANs. This helps to improve network performance and security by reducing unnecessary broadcast traffic.Rate this question:

- 10.
Which of the following features can be used to restrict communication between VLAN's
- A.
Access list
- B.
Mac-based authentication
- C.
Web-based authentication
- D.
Port-security
Correct Answer
A. Access listExplanation
Access lists can be used to restrict communication between VLANs. Access lists are a set of rules or filters that can be applied to a router or switch interface. They allow or deny traffic based on various criteria such as source or destination IP address, protocol, or port number. By configuring access lists, network administrators can control which VLANs can communicate with each other and restrict unwanted traffic between them.Rate this question:
