Fragment 4: size (781), offset value (492), flag (1)

the datagram contains a header of 20 bytes and a payload of 8 bits( that is 1 byte)

The data allowed = 1333 - 20 - 1 = 1312 B

The program to the given question can be given as:

program:

var1 = "Happy" #defining variable var1

var2= "Birthday" #defining variable var2

var3 = (var1+var2) *2 #defining variable var3 and calculate value

print (var3) #print value.

In the above python program, three variable is defined, that is var1, var2, and var3, in which variable var1 and var2 we assign a value, that is "Happy" and "Birthday".

In variable var3 we add the value of var1 and var2 variable and multiply by 2. It will print the variable value two times. and other options are not correct that can be defined as:

  • In option B and C, Both variable var1 and var2 print there values two times but in option B var1 value print two time and var2 value print one time only and option C var1 variable value is print only one time and var2 variable value is print two times that's why it is not correct.
  • In option C, Both variable var1 and var2 print there values two times that's why it is not correct.
