Question 8 of 42 Question 8 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. Why is a switch able to utilize bandwidth more efficiently than a hub? Because it is able to discern which messages can be ignored as spam and which are actually important to pass on. Because messages sent by a switch are compressed into a form that requires fewer bits. Because it recognizes the intended recipient for a particular message and is able to direct that message only towards that single device. all of the above Correct.Question 9 of 42 Question 9 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. Which of the following is a common trait of both routing and switching? Individual device addresses are used to direct messages. Routing and switching both involve the evaluation of which message to send first when there are multiple incoming messages. Used to move traffic from one network to another network.

Question 17 of 42 Question 17This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. How does a DNS relate to how a user interacts with IP addresses? A DNS provides individual computer devices and webpages with unique IP addresses so that users can locate those devices and pages and communicate with them. A DNS breaks down an IP address into manageable packets of data that can be processed individually. A DNS converts an English-like name provided by a user to its corresponding numerical IP address so that the user does not have to remember the numerical form. A DNS examines the IP address provided by the user and then identifies the location of the device associated with that IP address so that an information packet can be forwarded to that location. Correct. Question 18 of 42 Question 18 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. What part of an incoming packet does a router examine in order to determine the next location to send it to? destination IP address routing table the DNS alias any of the above, depending on where the packet originated Correct.

Question 21 of 42 Question 21 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully.What kind of tables does a DNS have? tables that list the MAC addresses of all individual devices connected to the Internet tables that help the server identify the location of each device based on its IP address tables that map out the location of major nodes and links in their region of the Internet so that important pathway decisions can be made tables that contain host IP addresses and their corresponding aliases Correct. Question 22 of 42 Question 22 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. Which of the following steps comes first in the process of communicating a message over the Internet? The local router decides the best first location to send the message. The message is placed into packets. The destination IP address is translated from an “external public” address to an “internal private” address. The message information is sent from the source computer to the Internet point of presence for that local network. Correct. Question 23 of 42 Question 23 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. What is the major advantage for communications provided by DNS services?DNS services provide a platform for communications between computers running different network protocols. Users are able to reach websites that they otherwise would not be granted access to. Users are far more likely to remember names for websites rather than the lengthy numerical addresses that would be needed without DNS services. DNS services do not provide any additional functionality, but they do speed all Internet communications up significantly. Correct. Question 24 of 42 Question 24 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully.

Question 26 of 42 Question 26 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. What are the two categories of concern in IAS? security and assurance access and stability integrity and security availability and confidentiality Correct. Question 27 of 42 Question 27 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. Which of the following is not a concern related to data integrity? Data should not be altered without a record of when, how, and by whom it was altered. Data must be collected in a manner that ensures its accuracy.Data must be entered into the system for storage correctly. Data must be stored in such a way that access is denied to those who should not see it, but is available to those who need to use it. Correct. Question 28 of 42 Question 28 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. Lisa is in charge of employee payroll for her company. Sensitive personal employee information must be collected for payroll purposes, including such things as addresses, social security numbers, and retirement account information. Lisa is one of only two employees in the company who have access to the password protected files where the information is stored. She is able to access that information either from a secure workstation at the office or through secure remote access from her personal computer at home. She is able to make changes to the information in those files, but those changes are always recorded and documented. If she opens one of the sensitive files, the other employee who has access to it cannot alter it in any way while she is using it. What is the violation of IAS principles in this scenario? Personal information should only be recorded if necessary, but if it is necessary to record it, it should be available publicly. Availability is compromised because the files are password protected, which might prevent access to the files by those who need to use the information. The fact that Lisa can access this private information remotely from home grants availability at the expense of integrity and security. There are no obvious violations of IAS principles in this scenario. Correct.

Question 41 of 42 Question 41 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. Which of the following statements accurately describes the benefits of computer networks in business settings? Computer networks provide many advantages for work processes today (cost savings, increased efficiency and productivity, etc.) without any significant drawbacks. Computer networks do provide small to moderate advantages to businesses who install, use, and maintain them properly, but most businesses find that that the costs, trouble, and increased risks involved make computer networks a bad choice. Computer networks provide many advantages to businesses, but one significant drawback is the tendency of employees to take advantage of their flexibility by working from home or other informal settings rather than coming into the central office. In most business settings, computer networks provide many significant benefits, but there is always a need to be aware of the increased risk associated with them. Correct.Question 42 of 42 Question 42 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. Why might a company’s software expenses decrease if they implement a computer network for their office? They can potentially share software over the network rather than purchasing copies of the software for each user. Networks run primarily using hardware, not software. A network allows users to communicate instantly with one another rather than using software for numerous steps of back and forth communication. The capabilities of networks automate many tasks that would otherwise have required human users.
