Which device should a technician use if he needs to connect multiple PCs in a home office to share files & printers ?
Switch
What is the best choice for connecting multiple PCs in a home office to share files & printers.
Switch
What allows devices to communicate with each other within the same local network, making it easy to share resources like files & printers?
Switch
What device is used to connect different networks & route traffic between them?
Routers
What are used to extend wireless network coverage
Access Points
If a small business wants to segment traffic between departments, which network device would help separate broadcast domains?
Routers
What is a device that separates broadcast domains?
Routers
What device operates at layer 3 of the OSI Model & can break up broadcast domains by routing traffic between different subnets or VLANs?
Routers
What layer do switches operate at ?
Layer 2 data link layer
What device works at layer 1 of the OSI Model & simply repeats incoming signals to all connected devices?
Hubs
What is Inter-VLAN routing?
the ability to route/send traffic between VLANs that are normally blocked by default
What is a VLAN? & What does it do?
-Virtual Local Area Network
-any broadcast domain that is partitioned & isolated in a computer network at the data link layer.
What are the 5 types of VLANs?
Management, Data, Voice, Default, Native
What device is used to connect a network to the internet?
Modem
An administrator needs to implement access control policies for inter-VLAN routing, which type of switch should be used?
Managed Switch
What type of switch should be used for implementing access control policies for inter-VLAN routing?
Managed Switches
What provides layer 3 functionality allowing administrators to configure VLANs & access control policies?
Managed Switches
What type of switches are used in storage area networks (SANs) & are not designed for inter-VLAN routing?
Fibre Channel Switch
What kind of switch allows for the addition or removal of modules?
Modular Switches
A company is installing new PoE security cameras, which device supplies power through the ethernet cable?
Injector
What connects to the network switch & provides both power & data to connected devices?
Injector
What are used to organize & connect ethernet cables in a network but do not supply power?
Patch Panels
What are used to extend the range of a network signal but do not supply power?
Patch Panels
What are used to extend the range of a network signal but do not supply power?
Repeaters
What are used to connect different network segments?
Bridges
What is a patch panel & what’s the point of it?
ports that allow for easy connection of multiple wires, while the labeling helps ensure that everything is connected properly.
The point of a patch panel is to provide an efficient and organized way to manage cables.
