Answer:
There are no additional components that can be added to the IPv4 protocol to improve its utility
Explanation:
The IPv4 protocol was developed in 1983 and is still the most widely used version worldwide. It consists of a 32-bit binary number that is normally represented in decimal notation, with four digits separated by dots that take values between 0 and 255.
This system limits the IPv4 protocol to 4,000 million different addresses, a figure that in the eighties seemed sufficient but that in practice has been scarce due to the revolution of mobile devices and the impending development of the Internet of Things ( IoT) that will trigger the number of devices connected to the network.
So, there are no additional components that can be added to the IPv4 protocol to improve its utility, since the world is running out of IPv4 addresses and is being replaced by IPv6.

Nfc relay attack
Explanation:
The NFC relay attack occurs when data is extracted by an attacker who puts himself in the middle of two parties having a communication with each other. As the message gets to a party, the attacker gets it and modifies it to their taste then passes it on.

Answer:
Option c is the correct answer for the above question.
Explanation:
- The super is a keyword in java which is used to call the parent class constructor from the child class constructor, but the only one thing is important to write the super is the constructor that the super keyword needs to be written as a first-line where it is used.
- The above question has three option which holds the constructor, in which option 1 and 2 holds the super keyword as the last line. So this option is not to hold the correct constructor.
- But option 3 will hold the Super as the first line, Hence this is the correct use of the constructor.
- And Only option c states about option 3 while the other is states about the other option. Hence option c is the correct answer.
