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.
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
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?
An administrator needs to protect rive websites with SSL certificates Three of the websites have different domain names, and two of the websites share the domain name but have different subdomain prefixes.
Which of the following SSL certificates should the administrator purchase to protect all the websites and be able to administer them easily at a later time?
A . One SAN certificate
B . One Unified Communications Certificate and one wildcard certificate
C . One wildcard certificate and two standard certificates
D . Five standard certificates
Answer:
Option A (One SAN certificate) is the right answer.
Explanation:
A vulnerability management certificate that permits many domain identities to be safeguarded by such a singular or unique certification, is considered a SAN certificate.Though on the verge of replacing common as well as accepted security credentials with either of these de-facto certifications.Other alternatives are not connected to the given scenario. Thus the above option is correct.

Explanation:
If your organization hires a new employee, what would you do to create a user account in the Linux system and add the account to a group? What commands would you use? What configuration files would you check and modify?
Following are the responses to this question:
The user account is "olivia".In the Linux system to see the account go to the "/home directory".For the configuration file we use ".bash_logout , .bash_profile, and .bashrc" files.Creating users:
We will use the useradd command to achieve this. Using that same command, you can create users who would log in or customers who would log in (in the case of creating a user for a software installation).
In its basic form, the command is as follows:
[Options] useradd usernameTake this user olivia, for instance. Assuming that you had been to issue the command prompt:
olivia has become a user.Users are added to the system without the need for a home directory and are unable to log on. It if we were using this rather than running the command without arguments?
sudo using useradd -m oliviaUsing the command above, a new user would be created, including a home directory that corresponded to the username. That means that you might now see the name "olivia" in the directory "/home".
But what about the lockout concern that was raised earlier? Both these methods are possible. After creating the user, you can enter the following command:
Password for olivia is: sudo passwd oliviaYou'll be requested to enter & verify your new password once you've completed the process. This unlocks the user profile, allowing them to log in.
This command might look like if you wanted to accomplish it in one go:
sudo useradd -m olivia -p PASSWORDYou should be using Passcodes as the login for the user olivia.
As soon as the user logs in, he or she can update their account password by using the password command to input their current password, and afterward entering/verifying their new one.
To create a user that has no personal account and cannot log in, execute the following instructions:
sudo use useradd as the-M USERNAME sudo use usermod as the -L USERNAMEThe user to be added is identified by USERNAME.
It establishes a user with really no root folder and prevents them from signing in with a second operation.
To add an existing user to a group on Linux, follow the instructions:
As root, log in to your accountUse the useradd instruction to add a new user (for example, useradd roman)If you'd like to log on as a new customer, type su plus that user's name.Entering the word "exit" will logout you from your account.Another way to add a user to a group under Linux would be to use the following syntax:
Alternatively, you can use the usermod command.The name of the club should be substituted for example group in this sentence.Example username should be replaced with the name of the user you'd like added.The following operations are performed when a new login is added to the system.
The user's home directory (/home/username by default) is now created.To set configuration files for the user's session, the following secret files are copied into another user's home directory..bash_logout
.bash_profile
.bashrc
/var/spool/mail/username includes the user's mail spool.The new user account is arranged in groups with the same name.Learn more:

You are the network administrator for the ABC Company. Your network consists of two DNS servers named DNS1 and DNS2. The users who are configured to use DNS2 complain because they are unable to connect to internet websites. The following shows the configuration of both servers:
Server Configurations:
DNS1: _msdcs.abc.comabc.com
DNS2: .(root)_msdcs.abc.comabc.com
The users connected to DNS2 need to be able to access the internet. What should be done?
Answer:
ABC Company
The action to take is to:
Delete the .(root) zone from the DNS2. Then configure conditional forwarding on the DNS2 server. If this is not done, the users will be unable to access the internet.
Explanation:
DNS forwarding enables DNS queries to be forwarded to a designated server, say DNS2, for resolution according to the DNS domain name. This stops the initial server, DNS1, that was contacted by the client from handling the query, thereby improving the network's performance and resilience and enabling the users to be connected to the DNS2 in order to access the internet.

cloud offers better protection compare to on premise?
Why is cloud better than on-premise? Dubbed better than on-premise due to its flexibility, reliability and security, cloud removes the hassle of maintaining and updating systems, allowing you to invest your time, money and resources into fulfilling your core business strategies.
The security of the cloud vs. on-premises is a key consideration in this debate. Cloud security controls have historically been considered less robust than onprem ones, but cloud computing is no longer a new technology. . A company running its own on-premises servers retains more complete control over security.

Calculate the total time required to transfer a 500KB file in the following cases. Assume an RTT of 50ms, a packet size of 2KB, and an initial 2xRTT of handshaking before data is sent. A. If the bandwidth is 2Mbps, what is the Bandwidth-Delay Product (BDP)
Answer:
i) Total time = 2457.73 secs
ii) BDP = 0.01 Mbyte
Explanation:
Packet size : 2 Kb = ( 2 * 8192 ) bits = 16384 bits
Bandwidth : 2Mbps = 2,000,000 bits/sec
RTT = 50 ms = 0.050 secs
i) Determine total time required to transfer 500 kB
= Initial handshake + Time for transmission of all files + propagation delay
= 2 x RTT + Time for transmission + RTT /2
Total time = ( 2 * 0.05 ) + (1500 * 1.6384 )+ ( 0.050 / 2 ) = 2457.73 secs
ii) Determine the Bandwidth-delay product
= data link capacity * RTT
= 2 Mbps * 50 ms = 100,000 = 0.01 MByte

Write a program that prompts the user to input an integer that represents cents. The program will then calculate the smallest combination of coins that the user has. For example, 27 cents is 1 quarter, 0 nickel, and 2 pennies. That is 27=1*25+0*5+2*1.
Example program run 1:
Enter number of cents: 185
Pennies: 0
Nickels: 0
Dimes: 1
Quarters: 7
Example program run 2:
Enter number of cents: 67
Pennies: 2
Nickels: 1
Dimes: 1
Answer:
The program in Python is as follows:
cents = int(input("Cents: "))
qtr = int(cents/25)
cents = cents - qtr * 25
dms = int(cents/10)
cents = cents - dms * 10
nkl = int(cents/5)
pny = cents - nkl * 5
print("Pennies: ",pny)
print("Nickels: ",nkl)
print("Dimes: ",dms)
print("Quarters: ",qtr)
Explanation:
The program in Python is as follows:
cents = int(input("Cents: "))
This calculate the number of quarters
qtr = int(cents/25)
This gets the remaining cents
cents = cents - qtr * 25
This calculates the number of dimes
dms = int(cents/10)
This gets the remaining cents
cents = cents - dms * 10
This calculates the number of nickels
nkl = int(cents/5)
This calculates the number of pennies
pny = cents - nkl * 5
The next 4 lines print the required output
print("Pennies: ",pny)
print("Nickels: ",nkl)
print("Dimes: ",dms)
print("Quarters: ",qtr)
