Answer: D.) LEFT
Explanation: LEFT is an excel function allows users to extract a specified number of characters starting from the left. The syntax goes thus :
=LEFT(text, [num_chars])
text: the original string in which characters are to be extracted.
num_chars : takes an integer, stating the number of characters to extract.
The proper function is also an excel function which sets the first character in each word to uppercase. The mid function is also used in text extraction starting from any position in the original string based on what is specified.
The LEN function is used to get the number or length of characters in a string.
Create a program that will find and display the largest of a list of positive numbers entered by the user. The user should indicate that he/she has finished entering numbers by entering a 0.
Answer:
This program is written using Python Programming language,
The program doesn't make use of comments (See explanation section for line by line explanation)
Program starts here
print("Enter elements into the list. Enter 0 to stop")
newlist = []
b = float(input("User Input: "))
while not b==0:
newlist.append(b)
b = float(input("User Input: "))
newlist.sort()
print("Largest element is:", newlist[-1])
Explanation:
This line gives the user instruction on how to populate the list and how to stop
print("Enter elements into the list. Enter 0 to stop")
This line creates an empty list
newlist = []
This line enables the user to input numbers; float datatype was used to accommodate decimal numbers
b = float(input("User Input: "))
The italicized gets input from the user until s/he enters 0
while not b==0:
newlist.append(b)
b = int(input("User Input: "))
This line sorts the list in ascending order
newlist.sort()
The last element of the sorted list which is the largest element is printed using the next line
print("Largest element is:", newlist[-1])
php Exercise 3: Function Write a function named word_count that accepts a string as its parameter and returns the number of words in the string. A word is a sequence of one or more non-space characters (any character other than ' '). For example, the call of word_count("hello, how are you?") should return 4. Constraints: • Do not use any data structures such as arrays to help you solve this problem. • Do not use the String function explode on this problem. • But you can declare as many simple variables like Integer, String, etc. as you like. Keep it simple.
Answer:
<?php
function word_count($string){ // function that takes a string a parameter and returns the number of words in that string
$space = 0; // this variable is used in order to detect space, new line and tab spaces in a string
$words = 1; // this variable is used to identify word presence in string
$include = $space; //used to maintain the state of $words and $space
$counter = 0; // this counts the number of words in the string
$i = 0; //this moves through each character of the string
while ($i < strlen($string)){ // iterates through every character of string until the last character of string is reached
if ($string[$i] == " "||$string[$i] == "\n" || $string[$i] == "\t") //if the space or new line or tab space is identified in the string
$include = $space; //set the state of include as space if the next character is a space newline or a tab space
else if ($include == $space) { //if next character is a word and current state i.e. $include holds $space
$include = $words; // then set the state i.e. $include as $words
++$counter; } //increments i to move to next character at each iteration
++$i; } //returns the number of words in a string
return $counter; }
$str = "Hello, how are you "; //sample string
echo "Words: " . word_count($str); // calls word_count function to return number of words in str.
?>
Explanation:
The program has a function word_count that accepts a string as its parameter and returns the number of words in the string. In the function there are three variables $space and $words and $include used as state variables. For instance $space identifies space, new line and tab spaces in the $string so it specifies that a space has occurred. $words identifies words in the $string so it specifies that a word has occurred. $include holds this state information. $i moves through every character of the $string and when a space occurs in the $string then the state $include is set to $space. When a word occurs then state $include is set to $words. $counter variable, which is used to count the number of words is incremented to 1 when previous state is $space and next character is a word character. Every time a word is seen in the string, this variable is incremented to 1 to keep track of number of words in the string. When $i reaches the end of the string then this loop stops and counter returns the number of words in the $string.

// This line initializes the expected string to empty string
string result = "";
//The for iteration loops through the number of terms the function is expected to return
for(int i = 1; i<= size_tn;i++)
{
//This line checks if the loop is less than the number of terms
if(i < size_tn)
{
//This string gets the current term of the progression
result+=to_string(a)+ ", ";
//This line calculates the next term
a+=d;
}
else
{
//This line calculates the last term
result+=to_string(a);
}
}
//This line returns the string containing the first n terms of the arithmetic progression
return result;
}
//The main function starts here
int main()
{
//This line declares the first term (a), the common difference (d) and the number of terms (size_tn)
int a,d,size_tn;
//This line prompts the user for the first term
cout<<"First Term: ";
//This line gets the first term
cin>>a;
//This line prompts the user for the common difference
cout<<"Common Difference: ";
//This line gets the common difference
cin>>d;
//This line prompts the user for number of terms
cout<<"Number of Terms: ";
//This line gets the number of terms
cin>>size_tn;
//This line calls the function to print the string containing the first n terms
cout<<get_ap_terms(a, d, size_tn);
return 0;
}
//Program ends here
In the Programming Process which of the following is not involved in defining what the program is to do:_____________ Group of answer choices
a. Compile code
b. Purpose
c. Output
d. Input
e. Process
Answer:
a. Compile code
Explanation:
In programming process, the following are important in defining what a program is to do;
i. Purpose: The first step in writing a program is describing the purpose of the program. This includes the aim, objective and the scope of the program. The purpose of a program should be defined in the program.
ii. Input: It is also important to specify inputs for your program. Inputs are basically data supplied to the program in order to perform a task. Valid inputs are defined in the program.
iii. Output: Many times, when inputs are supplied to a program the resulting effects are shown in the outputs. The way the output will be is defined in the program.
iv. Process: This involves the method by which inputs are being mapped into outputs. The process implements the functionality of the program by converting inputs into their corresponding outputs. The process is defined in the program.
Compile code is not a requirement in defining what a program is to do. It just allows the source code of the program to be converted into a language that the machine understands.
A Solutions Architect needs to build a resilient data warehouse using Amazon Redshift. The Architect needs to rebuild the Redshift cluster in another region. Which approach can the Architect take to address this requirement
Answer:
Explanation:
An Amazon Redshift data warehouse refers to a collection of computing resources that are known as nodes. These nodes are organized into a group called a cluster. In order to correctly replicate/rebuild this cluster in another region, the Architect needs to modify the Redshift cluster to take snapshots of the Amazon EBS volumes each day, sharing those snapshots with the other region. These snapshots will provide accurate and up-to-date information allowing for a correct rebuild of the Redshift cluster.
All the protocol layers of the internet (Application, Transport. Network) were originally without any security. TLS is one of the security architectures added later. In the Internet protocol stack. TLS is located:________. 1. right above the application layer 2. right below the application layer 3. right below the transport layer 4. right above the IP layer
Answer:
2. right below the application layer
Explanation:
TLS (Transport Layer Security) is an improved and more secured version of the SSL (Secure Socket Layer) used as cryptographic protocol for providing authentication and encryption over a network. It is initialized at the transport layer of the IP stack and finalized at the application layer. In other words, it is located between the transport and application layer of the Internet protocol stack. And this is necessary so that data received in the application layer from the transport layer are protected from start to end between these two layers.
Therefore, it is safe to say that the TLS is located right below the application layer.

Write a program that asks the user to input a positive integer and then calculates and displays the factorial of the number. The program should call a function named getN
Answer:
The program is written in python and it doesn't make use of any comment;
(See explanation section for line by line explanation)
def getN(num):
fact = 1
for i in range(1, 1 + num):
fact = fact * i
print("Factorial: ",fact)
num = int(input("Number: "))
if num < 0:
print("Invalid")
else:
getN(num)
Explanation:
The function getNum is defined here
def getN(num):
Initialize the result of the factorial to 1
fact = 1
Get an iteration from 1 to the user input number
for i in range(1, 1 + num):
Multiply each number that makes the iteration
fact = fact * i
Print result
print("Factorial: ",fact)
Ths line prompts user to input number
num = int(input("Number: "))
This line checks if user input is less than 0; If yes, the program prints "Invalid"
if num < 0:
print("Invalid")
If otherwise, the program calls the getN function
else:
getN(num)
Rijndael, AES, CCMP are same as well as different. They are same in terms of how encryption is done and different in terms of whether each one is a protocol, algorithm or a standard.CCMP is both, a protocol and a standard, Rijndael is:_________ a) standard only b) an algorithm c) a communications protocol. d) patented by US Government
Answer:
Option (b) is the correct answer to this question.
Explanation:
AES is based on Rijndael Algorithm.
The Rijndael algorithm enables a choice of block sizes and key sizes. The choices are for each of 128, 192, or 256 bits. Once NIST implemented Rijndael for AES, it only specified one block size,128 bits, but maintained three major lengths of selection. IEEE 802.11I go a step and further limits when both the main size and length of the block for 128 bits. It simplifies deployment and relieves users during development from having to make yet again another decision.
Other options are incorrect because they are not related to the given scenario.
If no other row matches, the router will select the ________ row as its best match. First Last either First or Last, depending on the circumstances neither First nor Last
Answer:
Last
Explanation:
Routing is a term in engineering which involves the process of selecting a path for traffic in a network or across multiple networks. It is applicable in circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. It is mostly used as a term for IP Routing.
Hence, in IP Routing, the first step is comparing the packet's destination IP address to all rows, followed by selecting the nest-match row. However, If no other row matches, the router will select the LAST row as its best match.

The is_positive function should return True if the number received is positive, otherwise it returns None. Can you fill in the gaps to make that happen?
The is_positive function should return True if the number received is positive, otherwise it returns None. Can you fill in the gaps to make that happen?
def is_positive(number):
if _____ :
return _____
Answer:
def is_positive(number):
if (number > 0):
return True
else:
return "None"
---------------------------------------------------------------------------------
Code Test and Sample Output:print(is_positive(6))
>> True
print(is_positive(-7))
>> None
----------------------------------------------------------------------------------
Explanation:The code above has been written in Python.
Now, let's explain each of the lines of the code;
Line 1: defines a function called is_positive which takes in a parameter number. i.e
def is_positive(number):
Line 2: checks if the number, supplied as parameter to the function, is positive. A number is positive if it is greater than zero. i.e
if (number > 0):
Line 3: returns a boolean value True if the number is positive. i.e
return True
Line 4: defines the beginning of the else block that is executed if the number is not positive. i.e
else:
Line 5: returns a string value "None" if the number is not positive. i.e
return "None"
All of these put together gives;
===============================
def is_positive(number):
if (number > 0):
return True
else:
return "None"
================================
An example test of the code has also been given where the function was been called with an argument value of 6 and -7. The results were True and None respectively. i.e
print(is_positive(6)) = True
print(is_positive(-7)) = None
Following are the python program to check input number is positive or negative:
Program:def is_positive(n):#defining the method is_positive that takes one variable in parameter
if (n > 0):#defining if block that check input number is positive
return True#return boolean value that is True
else:#else block
return "None"#return string value
n=int(input("Enter number: "))#defining n variable that input a number
print(is_positive(n))#using print method that calls and prints method return value
Output:
please find the attached file.
Program Explanation:
Defining the method "is_positive" that takes one variable "n" in the parameter.Inside the method, if conditional block is defined that checks the input number is positive, if it's true, it will return a boolean value that is "True". Otherwise, it will go to the else block, where it will return a string value that is "None".Outside the method, the "n" variable is declared to be an input number.After the input value, a print method is used that calls the "is_positive" method and prints its return value.Find out more about the method here:

James has a USB flash drive that he has used at work. The drive needs to be thrown away, but James wants to make sure that the data is no longer on the drive before he throws it away. What can James use to wipe the data clean?
a. Zero-fill utility
b. Format the drive
c. ATA Secure Erase
d. Smash the USB drive
Answer:
C. ATA Secure Erase
D. Smash the USB drive
Explanation:
Zero fill utility is a specialized way of formatting a storage device particularly secondary storage such as hard disk, flash drive e.t.c. In this process, the disk contents are overwritten with zeros. Once this has been done, undoing is essentially hard but possible. In most cases, this might just mean that the data content is corrupt and as such might still be recovered, maybe not in its pure entirety.
Formatting the drive on another hand does not essentially mean cleaning the drive and wiping off data. It just means that operating systems cannot see those data contents anymore. They are still present in the drive and can be recovered.
ATA Secure Erase is actually a way of completely and permanently erasing the content in a drive. Once the function has been done, undoing is not possible. Both the data content and even the data management table will be completely gone.
Smashing the USB drive is the surest way of cleaning data as that will permanently destroy the working components of the drive such as the memory chip. And once that happens then there's no drive let alone its contents.
