Answer:
The answer is B.
Explanation:
Radio Frequency Identification (RFID) is a technology that uses radio waves to secure objects, pair devices, tag them etc. and it is made up of a transmitter which emits radio waves and a receiver.
The example given in the question where Jamie listens to the communication between the RFID tag and the devide of the user and copies the information to later use it to gain access to the vehicle is an example of a replay attack.
Also called "eavesdropping & replay", the first part is the listening to the conversation to steal the data and the replay part is where he uses the information to gain access.
I hope this answer helps.

Answer: No estoy segura de cuál es la respuesta
Explanation:
Here you go. I added a constructor and a toString overload to make the object creation and printing as easy as possible.
public class student {
private String _id;
private String _name;
private String _address;
public student(String id, String name, String address) {
_id = id;
_name = name;
_address = address;
}
public String toString() {
return "Id: " + _id + "\nName: " + _name + "\nAddress: "+ _address;
}
public static void main(String[] args) {
student s1 = new student("S12345", "John Doe", "Some street");
System.out.println(s1);
}
}
