You need a network that provides a centralized authentication for your users. Which of the following logical topologies should you use?
- A.
VLAN's
- B.
Peer to Peer
- C.
Client/Server
- D.
Mesh
Correct Answer
C. Client/ServerExplanation
A client/server topology is the most suitable choice for providing centralized authentication for users. In this topology, there is a central server that manages user authentication and authorization, while the clients connect to the server for authentication purposes. This allows for a centralized and controlled access to resources, ensuring security and efficient management of user accounts. VLANs are used for network segmentation, peer-to-peer topology lacks centralized control, and mesh topology is more suitable for redundancy and fault tolerance, rather than centralized authentication.Rate this question:

You need a topology that is scalable to use in your network. Which of the following will you install?
- A.
Bus
- B.
Ring
- C.
Star
- D.
Mesh
Correct Answer
C. StarExplanation
A star topology is the most scalable option for a network. In a star topology, all devices are connected to a central hub or switch, allowing for easy expansion by simply adding more devices to the central hub. This makes it flexible and scalable, as new devices can be added without disrupting the entire network. Additionally, it provides better performance and reliability compared to other topologies like bus or ring, as any failure in one device does not affect the entire network. Therefore, installing a star topology would be the best choice for a scalable network.Rate this question:

Which of the phyiscal topologies has the least likelihood of having a collision?
- A.
Bus
- B.
Star
- C.
Ring
- D.
Mesh
Correct Answer
D. MeshExplanation
Mesh topology has the least likelihood of having a collision because it provides a dedicated point-to-point connection between each device. In a mesh network, each device is directly connected to every other device, eliminating the need for data to pass through multiple devices before reaching its destination. This reduces the chances of collisions as there is no shared medium for data transmission. In contrast, bus, star, and ring topologies involve shared media or a central hub, which increases the likelihood of collisions.Rate this question:

When the central concertrating device experiences a complete failure, all attached devices lose connectivity to the rest of the network
- C.
In a Star topology, a more exspensive type of host must be used when compared to the host used when implementing a phyiscal bus
- D.
It is more difficult to add stations and troubleshoot than with other topologies
Correct Answer
B. When the central concertrating device experiences a complete failure, all attached devices lose connectivity to the rest of the networkExplanation
In a Star topology, all devices are connected to a central concentrating device, such as a switch or hub. This central device acts as a single point of failure. If this central device experiences a complete failure, all the attached devices lose connectivity to the rest of the network. This is a disadvantage of the Star topology as it can result in a complete network outage if the central device fails.Rate this question:

You have a network with multiple devices and need to have a smaller broadcast domain while working with a tighter budget. Which of the following is the best solution?
- A.
Use a static IP address
- B.
Add more hubs
- C.
Implement more switches
- D.
Create VLAN's
Correct Answer
D. Create VLAN'sExplanation
Creating VLANs is the best solution for having a smaller broadcast domain while working with a tighter budget. VLANs allow for logical segmentation of a network, allowing devices to be grouped together based on their function or department. This reduces the size of the broadcast domain, as broadcasts are only sent to devices within the same VLAN. VLANs can be implemented using existing switches, making it a cost-effective solution compared to adding more hubs or switches. Using a static IP address would not address the issue of broadcast domain size.Rate this question:
