Answer: (B) Allow the firewall to accept inbound traffic to ports 80, 110, 143, and 443

Explanation:

Port 80 is used by HTTP, 110 by pop3 to retrieve emails from web servers, 143 by imap for internet messaging and 443 is used for TCP for websites using SSL. So if the firewall is allowed to accept inbound traffic to these ports 80,110,143 and 443 then it would be possible to retrieve emails.

Answer:

Option (C) FAT32 File System Type

Explanation:

  • FAT32 File System Type cannot be encrypted by the accounting users.
  • FAT stands for File Allocation Table. It is a file system architecture.
  • The File Allocation Table is an index table which contains the details about each cluster ( disk storage space ).
  • By traversing the File Allocation Table, the operating system gets the details the file ( where it is located ) and the size of the file.
  • The FAT32 file system contains more number of possible clusters.
  • In this system, 32 bits are used to store the total number of possible clusters.
  • In FAT32 file system, the transparent encryption is not supported.
  • So, option (C) is correct.
  • All other options are wrong options.

Write a program that asks the user for several days' temperatures and computes the average temperature for that period and how m
elena-14-01-66 [18.8K]

Answer:

#section 1

<em>no_of_days= int(input('How many days are we geting the average for: ')) </em>

<em>tem=[] </em>

<em>for i in range(no_of_days): </em>

<em>    a= int(input('Enter temperaure: input ' + str(i+1)+'  :')) </em>

<em>    tem.append(a) </em>

<em />

#section 2<em>     </em>

<em>average = round(sum(tem)/len(tem),2) </em>

<em>print('The Average is ',average) </em>

<em>gdays=[] </em>

<em>for i in tem: </em>

<em>    if i > average: </em>

<em>        gdays.append(i) </em>

<em> </em>

<em>print('The following days are greater than the average: ',gdays)</em>

Explanation:

The above code is written in python 3

#section 1:

An input is gotten for number of days that is to be used in the calculation, and an array is created to hold the temperature that will be inputted into the program.

A range of values from [0 - (no_of_days - 1)] is created from the number of days entered, this is done so that the FOR loop can iterate through every number and call for inputs.

The FOR loop prompts the user for an input based on the range and passes that input to an integer data type before appending it to the tem array.

#section 2:

The sum of the new list and the length is used to calculate the average and the it is rounded up to 2 DP, The average is then printed to the screen.

Another FOR loop is used to check which of the days are greater than the average and passes it to another array (<em>gdays)</em>, this array is also printed to the screen.

check the attachment to see how the code works.
