Select the correct statement(s) regarding IP addressing.
a. IPv4 and IPv6 addressing is fully compatible with one another.
b. CIDR address format represents a Class C network only used within an intranet.
c. Subnet masks are used with both class and classless IP addresses.
d. all statements are correct.

Answers

Yeah the answer is b

Subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.

What is an IP address?

A device on the internet or a local network may be identified by its IP address, which is a special address. The rules defining the format of data delivered over the internet or a local network are known as “Internet Protocol,” or IP.

Only C is correct, rest other statements are incorrect because:

a. IPv4 and IPv6 addressing is fully compatible with one another is incorrect. While IPv4 and IPv6 can coexist on the same network, they are not fully compatible with one another.

b. CIDR address format represents a Class C network only used within an intranet is incorrect. Classless Inter-Domain Routing (CIDR) is a technique used to allocate IP addresses more efficiently.

Therefore, subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.

Write a program that uses linear recursion to generate a copy of an original collection in which the copy contains duplicates of every item in the original collection. Using linear recursion, implement a function that takes a list as user-supplied runtime input and returns a copy of it in which every list item has been duplicated. Given an empty list the function returns the base case of an empty list.

Answers

Answer: b

Explanation:

Program using linear recursion to duplicate items in a list:

def duplicate_list(lst):

   if not lst:

       return []

   else:

       return [lst[0], lst[0]] + duplicate_list(lst[1:])

# Example usage

user_input = input("Enter a list of items: ").split()

original_list = [item for item in user_input]

duplicated_list = duplicate_list(original_list)

print("Duplicated list:", duplicated_list)

How can a program use linear recursion to duplicate items in a list?

By implementing a function that utilizes linear recursion, we can create a copy of an original list with duplicated items. The function duplicate_list takes a list lst as input and checks if it is empty. If the list is empty, it returns an empty list as the base case.

Otherwise, it combines the first item of the list with itself and recursively calls the function with the remaining items (lst[1:]). The duplicated items are added to the resulting list. This process continues until all items in the original list have been duplicated and the duplicated list is returned.

You are consulting with another medium sized business regarding a new database they want to create. They currently have multiple normalized source databases that need consolidation for reporting and analytics. What type of database would you recommend and why

Answers

Answer:

The enormous amount of data and information that a company generates and consumes today can become an organizational and logistical nightmare. Storing data, integrating it and protecting it, so that it can be accessed in a fluid, fast and remote way, is one of the fundamental pillars for the successful management of any company, both for productive reasons and for being able to manage and give an effective response to the customers.

Good big data management is key to compete in a globalized market. With employees, suppliers and customers physically spread across different cities and countries, the better the data is handled in an organization, the greater its ability to react to market demand and its competitors.

Databases are nowadays an indispensable pillar to manage all the information handled by an organization that wants to be competitive. However, at a certain point of development in a company, when growth is sustained and the objective is expansion, the doubt faced by many managers and system administrators is whether they should continue to use a database system, or if they should consider the leap to a data warehouse. When is the right time to move from one data storage system to another?

cpp Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Ex: If the input is:

Answers

Answer:

#include <iostream>

int main() {

 // The length of the list

 int l;

 // The array containing the numbers

 int *list;

 // Threshold, last value in array

 int thresh;

 

 // Read in first value and create an array with the size of that value

 scanf("%d", &l);

 list = (int*) malloc(l * sizeof(int));

 

 for(int i = 0; i < l; i++) {

   scanf("%d", &list[i]);

 }

 thresh = list[l - 1];

 // Print the values

 for(int i = 0; i < l - 1; i++) {

   if (list[i] <= thresh) {

     printf("%d ", list[i]);

   }

 }

 

 printf("\n");

 free(list);

}

Explanation:

The program assumes at least two values are provided. The length of the list and the threshold.

We first read in an integer, and find out how many more integers we need to read. We create an array with the appropriate size, and loop through to fill the array with values. We know the last value is the threshold, and so we do one more loop to compare the values in the array with the threshold.

Chassis intrusion detection is an option that can be enabled/disabled in the BIOS setup utility (if a BIOS comes equipped with this feature).Coupled with a hardware sensor mounted insided the computer case, this functionality can be used to check if the case was opened and display a notification alert during next boot.
a. True
b. False

Answers

Answer: True

Explanation:

Chassis intrusion detection is simply a vital security feature which is used typically by large corporate networks. It's simply an intrusion detection method which can be used in alerting a system administrator when there's a situation whereby a person opens a computer case which can then be investigated in order to know if the computer hardware has been tampered with.

It should also be noted that the chassis intrusion detection can then be either enabled or disabled in the BIOS setup utility if a BIOS comes equipped with this feature.

The correct option is True.
