B. Longer passwords
C. Force use of all four types of characters (uppercase, lowercase, numbers, symbols)
D. Computer generated passwords
Answer:
B. Longer passwords
Explanation:
If the password is longer, it requires more incorrect attempts to find it, so the system could identify a potential hacker attempt. Smaller but more complex passwords could be identified by mistype or forgotten passwords.
An office manager must choose a five-digit lock code for the office door. The first and last digits of the code must be odd, and no repetition of digits is allowed. How many different lock codes are possible?
Answer:
6720 lock codes
Explanation:
The numbers to be chosen from are:
0 1 2 3 4 5 6 7 8 9
The odd numbers are five in number which are: 1 3 5 7 9
The even numbers are five in number which are: 0 2 4 6 8
If the first number is odd, therefore, it can be chosen in five ways
After the first number is chosen, there are 4 left odd numbers so the last number can be chosen in four ways.
There are 8 left numbers after they are chosen, so the second number can be chosen in eight ways
Third number can be chosen similarly, in seven ways
Fourth number can be chosen in six ways
Hence, the number of different combinations are:
5*4*8*7*6 = 6720 combinations

Assume you are a network consultant for a company that is designing a private WAN to communicate between five locations spread throughout a city. You want to tell the company president that this WAN will use a design for maximum uptime to all locations. Which of the designs should you use
Answer:
A mesh network design
Explanation:
In designing local area networks, we can follow one of several network topologies, some of these are; bus, star, ring, star-ring hybrid, mesh, etc. In a mesh topology, all the PCs are inter-connected to each other such that the computers do not send signals, they also act as signal relay to others within the network, considering that in this question scenario the goal is to acheive maximum uptime at all locations, a mesh design will be the best.
Final answer:
For a private WAN with maximum uptime, a mesh topology should be used due to its redundancy, with a full mesh offering the highest resilience. However, due to potential high costs, a partial mesh might be deployed, prioritizing critical connections and possibly using Quality of Service features for additional reliability.
Explanation:
If you are consulting for a company that needs a private Wide Area Network (WAN) with maximum uptime between its five locations spread throughout a city, the most robust design you should recommend is a mesh topology. A mesh topology provides each location with a direct connection to every other location. This redundancy means that if any single connection fails, the network communication can still proceed uninterrupted via alternative routes. For even greater resilience, you could consider a full mesh design, where each node has a direct connection to each other node, ensuring the highest level of redundancy and uptimes.
However, full mesh networks can be costly due to the high number of links and networking equipment required. An alternative with a balance of cost and resilience would be a partial mesh network, where not all systems are directly connected, but there are still enough interconnections to maintain communication in case one or a few links go down. It is essential to evaluate the criticality of each site to determine which connections are most necessary. Additionally, implementing Quality of Service (QoS) features and having backup links for the most critical connections will further enhance the network's robustness.

b. require more processing by each computer in the network than in star or ring networks
c. do not use decentralized routing
d. do not have much capacity wasted by network status information
e. do not have many possible routes through the network to prevent one circuit from becoming overloaded
Answer:
B) Require more processing by each computer in the network than in star and ring networks
Explanation:
Meshnet which refers to mesh networks is one of the topologies of computer networks. In this topology, the nodes are all connected directly to each other and to as many many other nodes that cooperate with each other (nodes here refers to PCs, bridges routers etc), this kind of connection prevents dependence on a single node for communication as all nodes participates in the passing of information, as a result each computer in a mesh requires more processing work than in star and ring networks.
An organization has had problems keeping track of new devices being placed on the network. Which of the following tools should be used to identify where devices reside on the network?
A) Tcpdump
B) Nslookup
C) Nmap

Explanation:In the 1950s, the three major networks (ABC, NBC, and CBS) developed prime-time shows that would appeal to a general family audience, including the domestic sitcom, a generic family comedy that was identified by its character-based humor and usually set within the home. Shows like Leave It to Beaver and Father Knows Best became iconic examples of this genre, embodying the era's idealized vision of the nuclear family. These series portrayed a wholesome, predictable domestic life that contrasted sharply with the uncertainties of the Cold War era, offering viewers a comforting escape into an idealized American domesticity.
The domestic sitcoms of the 1950s played a critical role in shaping viewer perceptions of the ideal American family life. By focusing on lighthearted, relatable family situations and presenting noncontroversial content intended for all ages, these shows catered to the broadest possible audience. This programming strategy helped the major networks secure a dominant share of prime-time viewership, with families across the country tuning in to enjoy shared viewing experiences that reinforced traditional values and norms.

You can create an absolute cell reference by placing a ____ in front of both the column letter and the row number of the cell address.
Answer:
Dollar sign ($)
Explanation:
When working with formulas in microsoft excel, we may find ourselves copying formulas accross different cells, this is done by cell referencing and there two types of cell references, the absolute and relative. An absolute reference to a cell simply means that the cell is "locked" and its rows and columns are not going to change when they are copied. So when an absolute referenced formula is copied to another cell, it remains constant. This is unlike the relative reference where the formula changes relative to the new location where it is copied to. To accomplish an absolute reference, the dollar sign ($) is placed in the front of both the letter and number representing the column and row respectively like this $A$5.
An absolute cell reference in Excel can be created by placing a $ symbol before both the column letter and the row number of the cell address, such as $A$1.
Explanation:In Excel, you can create an absolute cell reference by placing a $ symbol in front of both the column letter and the row number of the cell address. For example, if you would like to make cell A1 an absolute reference, you would write it as $A$1. This means that no matter where you copy and paste this formula, it will always refer to cell A1. The use of $ keeps the reference constant, or 'absolute).
