Chapter 1 Questions Flashcards
Which devices can provide connectivity
between two different subnets?
(Choose two)
A) Unmanaged switch
B) Layer 2 switch
C) Layer 3 switch
D) Bridge
E) Router
C) Layer 3 Switch
&
E) Router
Routers have the routing table that keeps track of subnets. Layer 2 switches DO NOT have any awareness of IP addressing at all, and subnets are an IP addressing concept. Layer 3 switches take the routing table and build an expression of the routing table in hardware.
What do we call any computing device
connected to a network?
A) Client
B) Server
C) Station
D) Node
D) Node
In a network, a node is the connection point among network devices such as routers, printers, or switches that can receive and send data from one endpoint to the other. Like networks, nodes can also be used to describe anything that uses a network to communicate. If it has an IP address, it can be a node.
What are capabilities of Layer 3
switches? (Choose two)
A) Can connect and segment two different
departments
B) Can route between networks
C) Operates as a Wi-Fi access point
D) Provide sophisticated firewall services
E) Can operate as an IDS
A) Can connect and segment two different
departments (Switch)
&
B) Can route between networks. (Router)
Using the process of elimination, D and E are off the table because both are security features. Layer 3 Switches do not act as firewalls or operate as an intrusion detection system. Same with C as switches do not have Wi-Fi abilities. Which leaves us with A and B.
Switches are good at segmentation, they have the ability to separate and connect. Departments are very much aligned towards different VLANs. In networking each department should be on a separate VLAN. So Departments = VLANs and Layer 3 switches can absolutely communicate across different VLANs. It’s the main device used to facilitate communications across VLANs. Layer 2 switches can not. Layer 3 switches also have routing tables so they can route packets to different networks or subnets.
