M2Q1: Networking Overview Flashcards
Module 2: Quiz 1
A network technician needs to connect a user’s PC to the wired Ethernet network. What is the BEST device the technician should use to connect the PC into the wired network?
A. Server
B. Hub
C. Switch
D. Wireless Access Point
C. Switch
Explanation: Switches and Hubs are used to connect wired nodes to the network. Switches are intelligent devices that learn MAC addresses and have better performance than hubs. Therefore a switch should always be used as the best option over a hub.
Switches make intelligent switching decisions by learning which devices are connected to them. Which of the following types of addresses does a switch learn about from connected hosts?
A. Layer 3 Address
B. MAC Address
C. Unicast Address
D. IP Address
B. MAC Address
Explanation: Switches learn the MAC address of connected hosts and keep them stored in the MAC address table.
The physical connections between network devices, either wired or wireless, are known as the network ______________.
A. Access
B. Media
C. Hub
D. Cable
B. Media
Explanation: The connections between devices are collectively referred to as network media and individually referred to as a network medium.
This type of device uses IP addresses to determine where to send network traffic.
A. Router
B. Hub
C. WAP
D. Server
A. Router
Explanation: Routers make decisions to send traffic from one network to another network based on the destination IP address in the IP packet. The IP address of a host determines which network it belongs to and using this information the Router can determine which local interface or neighboring router to route the traffic to.
This type of device serves as the gateway (aka default gateway) for IP traffic to leave the LAN.
A. Router
B. Hub
C. WAP
D. Server
A. Router
Explanation: The device that a host must send traffic to for leaving the local LAN and talking to another network is referred to as a gateway or a default gateway. Since routers are the devices that are capable of sending traffic from one network to another network they are also the default gateway for a LAN.
This type of device is a workstation used by an end user which provides the user with access to the network.
A. Switch
B. LAN
C. WAN
D. Client
D. Client
Explanation: The hosts or end-user devices on a network are referred to as Clients.
This Type of device provides a client with network access over wireless media.
A. Wireless Access Point
B. Hub
C. Wired Access Point
D. Switch
A. Wireless Access Point
Explanation: Wireless Access Points, also knowns as WAPs, APs, Access Points, or Wireless APs are the devices that wireless hosts connect to for access to the network.
This type of device can be local to the network or in a remote location and provides services to clients such as sharing of resources and files.
A. Router
B. Client
C. Server
D. Switch
C. Server
Explanation: Servers are the computers on networks that provide services to Clients. Servers can reside on the local network (such as local file servers) or on a remote network (such as web servers that host websites).
Hubs should be used instead of switches because hubs provide for better network performance than switches.
A. True
B. False
B. False
Explanation: Switches provide much better performance than that of hubs and should always be used instead of a hubs. Hubs can still be used, but are rarely seen in larger enterprise networks due to their poor performance in comparison with switches.
