Question 1 of 24
1. Question
3 pointsA company is contemplating whether to use a client/server or a peer-to-peer network. What are three characteristics of a peer-to-peer network? (Choose three.)Correct
Incorrect
Because network devices and dedicated servers are not required, peer-to-peer networks are easy to create, less complex, and have lower costs. Peer-to-peer networks also have no centralized administration. They are less secure, not scalable, and those devices acting as both client and server may perform slower.Hint

Question 6 of 24
6. Question
1 pointsWhich area of the network would a college IT staff most likely have to redesign as a direct result of many students bringing their own tablets and smartphones to school to access school resources?Correct
Incorrect
An extranet is a network area where people or corporate partners external to the company access data. An intranet simply describes the network area that is normally accessed only by internal personnel. The wired LAN is affected by BYODs (bring your own devices) when the devices attach to the wired network. A college wireless LAN is most likely used by the tablet and smartphone. A wireless WAN would more likely be used by college students to access their cell provider network.Hint

Question 19 of 24
19. Question
2 pointsA user is implementing security on a small office network. Which two actions would provide the minimum security requirements for this network? (Choose two.)Correct
Incorrect
Technically complex security measures such as intrusion prevention and intrusion prevention systems are usually associated with business networks rather than home networks. Installing antivirus software, antimalware software, and implementing a firewall will usually be the minimum requirements for home networks. Installing a home wireless network will not improve network security, and will require further security actions to be taken.Hint

Question 23 of 24
23. Question
4 pointsMatch each characteristic to its corresponding Internet connectivity type. (Not all options are used.)
Sort elements
- high bandwidth connection that runs over telephone line
- typically has very low bandwidth
- not suited for heavily wooded areas
- uses coaxial cable as a medium
- typically uses a T1/E1 or T3/E3 circuit
-
DSL
-
dialup telephone
-
satellite
-
cable
Correct
Incorrect
DSL is an always-on, high bandwidth connection that runs over telephone lines. Cable uses the same coaxial cable that carries television signals into the home to provide Internet access. Dialup telephone is much slower than either DSL or cable, but is the least expensive option for home users because it can use any telephone line and a simple modem. Satellite requires a clear line of sight and is affected by trees and other obstructions. None of these typical home options use dedicated leased lines such as T1/E1 and T3/E3.Hint

Question 24 of 24
24. Question
3 pointsMatch the definition to the security goal. (Not all options are used.)
Sort elements
- only the intended recipients can access and read the data
- the assurance that the information has not been altered during transmission
- the assurance of timely and reliable access to data
- only made possible by requiring validation of the receiver
- only encrypted connections (VPNs) are allowed to transfer data
-
ensuring confidentiality
-
maintaining integrity
-
ensuring availability
Correct
Incorrect
Data integrity verifies that the data has not been altered on the trip between the sender and the receiver. A field calculated by the sender is recalculated and verified to be the same by the receiver. Passwords and authorization maintain control over who has access to personal data. Redundant devices and links attempt to provide 99.999% availability to users. Integrity is made possible by requiring validation of the sender, not the destination. VPNs are not the only secure method by which data can be transferred confidentially.Hint
