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.

If I have an Animal superclass with a Mammal subclass, both concrete and both having a method called eat() with identical signat
Katarina [22]

Answer:

(c) the dynamic type of reference will determine which of the methods to call.

Explanation:

Polymorphism in Object Oriented Programming typically means the same method name can cause different actions depending on which object it is invoked on. Polymorphism allows for dynamic binding in that method invocation is not bound to the method definition until the program executes.

So in the case of Animal superclass and Mammal subclass, both having a method called eat() with identical signatures and return types, depending on which reference, the correct method eat() will be called dynamically upon execution.

For example, if we have the following;

================================

<em>Mammal mammal = new Animal();</em>

<em>mammal.eat()</em>

================================

The eat() method that will be called is the one in the Mammal subclass.

However, if we have;

================================

<em>Animal animal = new Animal();</em>

<em>animal.eat()</em>

================================

The eat() method of the Animal superclass will be called.

kherson [118]

Answer:

Step by step code along with explanation and output is given below

Explanation:

We can solve this problem using if elif else approach

def main():

# prompts the user to enter an integer from 1 to 10

 num = int (input('Enter a number in the range of 1 to 10:\n'))

# using the if elif print out the roman numeral from 1 to 10

 if num == 1:

   print ('Roman Numeral for 1 is I')

 elif num == 2:

   print ('Roman Numeral for 2 is II')

 elif num == 3:

   print ('Roman Numeral for 3 is III')

 elif num == 4:

   print ('Roman Numeral for 4 is IV')

 elif num == 5:

   print ('Roman Numeral for 5 is V')

 elif num == 6:

   print ('Roman Numeral for 6 is VI')

 elif num == 7:

   print ('Roman Numeral for 7 is VII')

 elif num == 8:

   print ('Roman Numeral for 8 is VIII')

 elif num == 9:

   print ('Roman Numeral for 9 is IX')

 elif num == 10:

   print ('Roman Numeral for 10 is X')

# using the else print out error message whenever user enters any other number not listed above

 else:

   print ('Error! Wrong Input')

# call the main function

main()

Output:

Enter a number in the range of 1 to 10:

6

Roman Numeral for 6 is VI

Enter a number in the range of 1 to 10:

15

Error! Wrong Input
