Explain why an organization's firewall should block outgoing packets the source addresses of which are not in the organization's address space.
Answers
Answer:
A firewall is used to monitor and control incoming and outgoing (or in better terms, inbound and outbound) traffic in a network based on some pre-defined security rules set by either an individual or a business.
Now, using firewall to block outgoing packets that have source addresses which are not in an organization's address space means rejecting requests that, though originate from the organization's address space, are not in the organization's allowable address.
This is necessary and of utmost importance because even though an hacker (or simply an attacker) gains access into the organization's network, there is a limit to what harm they can do. If for example, they manage to get some malicious programs into the system's via network processes such as using infected e-mails or using a browser, they might also want to make some requests to the Internet to get some additional programs downloaded which altogether is harmful to the system. Disabling or blocking outgoing packets or traffic will stop this combined hazard from happening.

Answer:
126=01111110
Explanation:
To solve this you simply have to get the sum of all your numbers to be equal to the number on the left using the biggest numbers possible
For 126,
First you look at 128, since 128>126 we can't use this and leave it as 0
126>64 so we put that as 1
We then subtract this 64 from 126 and get 62
Since 62>32 we put 32 as 1 and subtract 32 from 62
Then we see that 30>16 and put 16 as 1 and subtract 16 from 30
Now we have 14, since 14>8 we put 8 as 1 and subtract 8 from 14
Now we have 6, since 6>4 we put 4 as 1 and subtract 4 from 6
Lastly we have 2==2, since 2 can go into 2 we would put 2 as 1 and then subtract 2 from 2
Now we have 0 left and don't have to do anything with 1, so we leave it as 0
When you put it all together, you get 01111110

Answers
Creation of Truth Table Based on the logical statement, we can create a truth table as shown below:
A B (not A) (not A) and B (not A) and B or A A or (not A) and B 0 0 1 0 1 0 0 1 0 0 1 0 1 1 0 1 1 0 1 1 1 0 1 1 0 1 1 0 1 1 1
The first two columns show the input values, the next column shows the output of the NOT gate, then the output of the AND gate, then the output of the OR gate and finally the output of the logical statement.
We can observe that the output of the logical statement is the same as the output of the OR gate.
Given the logical circuit, we are required to perform two actions on it. Firstly, convert the circuit into a logical statement. Secondly, create a truth table based on the circuit/statement. Let's understand how to do these actions one by one:Conversion of Circuit into Logical Statement.
The given circuit contains three components: NOT gate, AND gate and OR gate. Let's analyze the working of this circuit. The two input variables A and B are first passed through the NOT gate, which gives the opposite of the input signal.
Then the NOT gate output is passed through the AND gate along with the input variable B. The output of the AND gate is then passed through the OR gate along with the input variable A.We can create a logical statement based on this working as: (not A) and B or A. This can also be represented as A or (not A) and B. Either of these statements is correct and can be used to construct the truth table.
Creation of Truth Table Based on the logical statement, we can create a truth table as shown below:
A B (not A) (not A) and B (not A) and B or A A or (not A) and B 0 0 1 0 1 0 0 1 0 0 1 0 1 1 0 1 1 0 1 1 1 0 1 1 0 1 1 0 1 1 1
In the truth table, we have all possible combinations of input variables A and B and their corresponding outputs for each component of the circuit.
The first two columns show the input values, the next column shows the output of the NOT gate, then the output of the AND gate, then the output of the OR gate and finally the output of the logical statement.
We can observe that the output of the logical statement is the same as the output of the OR gate.

Your company has been assigned the 194.10.0.0/24 network for use at one of its sites. You need to calculate a subnet mask that will accommodate 60 hosts per subnet while maximizing the number of available subnets. What subnet mask will you use in CIDR notation?
Answers
To accommodate 60 hosts per subnet while maximizing the number of available subnets, we need to use a subnet mask that provides enough host bits and subnet bits.
How to calculateTo calculate the subnet mask, we determine the number of host bits required to accommodate 60 hosts: 2^6 = 64. Therefore, we need 6 host bits.
Subsequently, we determine the optimal quantity of subnet bits needed to increase the quantity of accessible subnets: the formula 2^n >= the amount of subnets is used. To account for multiple subnets, the value of n is set to 2, resulting in a total of 4 subnets.
Therefore, we need 2 subnet bits.
Combining the host bits (6) and subnet bits (2), we get a subnet mask of /28 in CIDR notation.

What kind of variable is measured using 2 different values
Answers
A variable that is measured using two different values can be classified as a categorical variable or a binary variable.
Depending on the nature of the values, a variable can be classified as:
1)Categorical Variable: If the two different values represent distinct categories or groups, the variable is considered categorical. In this case, the variable can take on only one of two possible values.
Examples include gender (male/female), presence/absence of a certain trait, yes/no responses, or any other classification with mutually exclusive categories.
2)Binary Variable: If the two different values represent two distinct outcomes or states, the variable can be classified as a binary variable. Binary variables are often used in statistics, machine learning, and hypothesis testing.
Examples include success/failure, true/false, 1/0, or positive/negative results.
It's important to note that the distinction between categorical and binary variables lies in the nature of the values and the underlying meaning they convey.
Categorical variables can have more than two categories, while binary variables specifically refer to variables with only two possible values.

Compare and contrast predictive analytics with prescriptive and descriptive analytics. Use examples.
Answers
Explanation:
Predictive, prescriptive, and descriptive analytics are three key approaches to data analysis that help organizations make data-driven decisions. Each serves a different purpose in transforming raw data into actionable insights.
1. Descriptive Analytics:
Descriptive analytics aims to summarize and interpret historical data to understand past events, trends, or behaviors. It involves the use of basic data aggregation and mining techniques like mean, median, mode, frequency distribution, and data visualization tools such as pie charts, bar graphs, and heatmaps. The primary goal is to condense large datasets into comprehensible information.
Example: A retail company analyzing its sales data from the previous year to identify seasonal trends, top-selling products, and customer preferences. This analysis helps them understand the past performance of the business and guide future planning.
2. Predictive Analytics:
Predictive analytics focuses on using historical data to forecast future events, trends, or outcomes. It leverages machine learning algorithms, statistical modeling, and data mining techniques to identify patterns and correlations that might not be evident to humans. The objective is to estimate the probability of future occurrences based on past data.
Example: A bank using predictive analytics to assess the creditworthiness of customers applying for loans. It evaluates the applicants' past financial data, such as credit history, income, and debt-to-income ratio, to predict the likelihood of loan repayment or default.
3. Prescriptive Analytics:
Prescriptive analytics goes a step further by suggesting optimal actions or decisions to address the potential future events identified by predictive analytics. It integrates optimization techniques, simulation models, and decision theory to help organizations make better decisions in complex situations.
Example: A logistics company using prescriptive analytics to optimize route planning for its delivery truck fleet. Based on factors such as traffic patterns, weather conditions, and delivery deadlines, the algorithm recommends the best routes to minimize fuel consumption, time, and cost.
In summary, descriptive analytics helps organizations understand past events, predictive analytics forecasts the likelihood of future events, and prescriptive analytics suggests optimal actions to take based on these predictions. While descriptive analytics forms the foundation for understanding data, predictive and prescriptive analytics enable organizations to make proactive, data-driven decisions to optimize their operations and reach their goals.
