Which of the following regenerates a signal and broadcasts it to every computer connected to it?
a - Hub b - Switch c - router d - Firewall |
a - hub
|
|
|
Which of the following is not a central connecting device?
a - hub b - switch c - SOHO router d - Windows 7 client |

|
|
|
Send and receive data simultaneously is called
a - half duplex b - full duplex c - simplex d - 100 Mbps |
b - full duplex
|
|
|
Give the maximum length requirements for the following cabling technologies:
1. 100Base-TX 2. 100Base-FX 3. 10Base2 4. 10Base5 |
1. Twisted pair - 100 meters
2. Fiber optic - 200 meters 3. Coaxial (AKA Thinnet) - 185 meters 4. Coaxial (AKA Thicknet) - 500 meters |
|
|
What type of network is based on the star topology?
a - Wireless infrastructure mode networking b - FDDI c - 100BaseT d - Wireless ad hoc mode network |
c - 100BaseT Ethernet, the most common network topology where each computer is individually wired to a central connecting device (hub, switch, or SOHO router) with twisted pair cabling.
|
|
|
Which of the following networks is wired with a ring topology?
a - Wireless ad hoc b - Wireless infrastructure c - Fiber distributed data interface (FDDI) d - 100BaseT Ethernet e - X.25 packet switching |
c - FDDI is based on a ring topology with two counter-rotating rings. If a break occurs at any point, it automatically switches to a single ring that loops back at the point of failure.
This type of network uses fiber optic cable. |
|
|
Which of the following networks is wired with a mesh topology?
a - Wireless ad hoc b - Wireless infrastructure c - Fiber distributed data interface (FDDI) d - 100BaseT Ethernet e - X.25 packet switching |
e - X.25 packet switching is a WAN technology that is effectively based on a mesh topology.
|
|
|
Which of the following networks is wired with a star topology (select 2)?
a - Wireless ad hoc b - Wireless infrastructure c - Fiber distributed data interface (FDDI) d - 100BaseT Ethernet e - X.25 packet switching |
b - Wireless infrastructure mode networking acts like a start topology, but without wires. Wireless computers connect through a WAP which in turn is connected to a wired network.
d - Ethernet is based on a start topology with multiple devices connecting to a central hub or switch. |
|
|
What are two names for the ethernet plug?
a - RJ44 b - RJ45 c - 8P8C d - RJ8C |
b and c are the correct answers.
8P8C stands for "8 pin 8 conductors." pg 6 |
|
|
T/F
Broadcast data is sent to every host on a network while unicast data is sent to one host only. |
True. The ethernet switch made it possible for data to be sent to specific hosts.
Pg 10 |
|
|
What is the quickest and best way to check whether or not TCP/IP is installed correctly to a network adapter, even if not physically connected?
|
Ping the loopback address, 127.0.0.1
Pg 13-14 |
|
|
Define 2 types of perimeter networks
|
1. Back-to-back config - the DMZ exists between two firewalls
2. 3-leg perimeter config - Internet -> firewall -> DMZ and LAN (both connect to the non-public side of the firewall) Pg 17 |
|
|
Which network topologies utilize a token passing system?
a - star b - bus c - ring d - FDDI (fiber distributed data interface) e - token ring |
d and e. Token ring and FDDI networks do not broadcast data, but use a token circulated through the network (there can be 1 or 2) to distribute data and avoid collisions.
While FDDI networks utilize ring topology completely, token ring networks are only such logically. Physically they are star-configured. pg 20 |

|
You want to connect your PC to a group of hosts that were segmented from the regular network. What kind of network is this?
a - LAN b - WLAN c - WAN d - VLAN |
d - This is a virtual LAN or VLAN
Pg 27 |
|
|
What kind of topology can be defined by connecting several hubs to a switch?
|
A star topology.
|
|
|
At what speed (in Mbps) does an 802.3u Ethernet network operate?
a - 10 Mbps b - 100 Mbps c - 1000 Mbps |
b
|
|
|
Which network architecture is physically a star and logically a ring?
|
Token Ring
|
|
|
At what speed (in Mbps) does an 802.3ab Ethernet network operate?
a - 10 Mbps b - 100 Mbps c - 1000 Mbps |
c
|
|
|
What type of network topology can be defined as connecting several computers together in a circle without the use of a hub or switch?
a - Mesh b - Star c - Bus d - Ring |
d - Ring
|
|
|
You are tasked with creating a network that can support 50 users. Which networking model should you choose?
a - client server b - peer-to-peer |
a - client server
|
|
|
You need to install 5 new computers, each of which must communicate in full duplex at 1 Gbps over twisted pair cabling already installed. Which Ethernet standard should you utilize?
|
Ethernet 802.3ab
|
|
|
A computer on your network is not connecting to certain network devices correctly. The IP address information is as follows:
192.168.1.210 255.254.0.0 Fix the subnet mask to solve this problem. |
Since the IP address is a class C private address, change the subnet mask to 255.255.255.0.
