if the search column for a VLOOKUP contains a duplicate value, which value will VLOOKUP return?
a. the value of the last match
b. it will return both values
c. it will return an error (#duplicate), since the research column must be unique
d. the value of the first match
If the search column for a VLOOKUP contains a duplicate value, a value which VLOOKUP will return is: D. the value of the first match.
What is VLOOKUP function?A VLOOKUP function can be defined as a type of function that is typically used to look up a value in a specific column in Microsoft Excel. Generally speaking, a VLOOKUP is represented by this syntax in Microsoft Excel;
VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
Where:
lookup_value represents the value to be searched in the first column of a spreadsheet.table_array represents the range of cells containing data set.col_index_num represents the column number from which a value can be retrieved.range_lookup represents an optional argument i.e (FALSE) or (TRUE).In conclusion, a VLOOKUP function would return the value of the first match when the search column contains a duplicate value.

CHALLENGES
Prior to completing a challenge, insert a COMMENT with the appropriate number.
1) Get an integer from the keyboard, and print all the factors of that number. Example, using the number 24:
Factors of 24 >>> 1 2 3 4 6 8 12 24
2) A "cool number" is a number that has a remainder of 1 when divided by 3, 4, 5, and 6. Get an integer n from the keyboard and write the code to determine how many cool numbers exist from 1 to n. Use concatenation when printing the answer (shown for n of 5000).
There are 84 cool numbers up to 5000
3) Copy your code from the challenge above, then modify it to use a while loop instead of a for loop.
5) A "perfect number" is a number that equals the sum of its divisors (not including the number itself). For example, 6 is a perfect number (its divisors are 1, 2, and 3 >>> 1 + 2 + 3 == 6). Get an integer from the keyboard and write the code to determine if it is a perfect number.

6. Why don't WE need to know exact IP addresses for the devices that we use?
Answer:
We don't need to know the exact IP addresses for the devices that we use because our devices use a network such as the internet to communicate with each other, and the network itself is responsible for routing the data between devices using their IP addresses. When we use our devices to access a network, the network assigns our device a temporary IP address, which is used to identify and communicate with our device within the network. This means that we only need to know the IP address of the network itself, rather than the specific IP addresses of all the devices that we use.
