Answer:
Elastic IP address
Explanation:
Elastic IP addresses are static, persistent public IP addresses which can be associated and disassociated with the instance, as required.
This will provide the best failover solution that will keep same IP address on a new instance.
Answer:
customers += newCustomer;
Explanation:
The operator += expands into + and assignment. The assignment is not overloaded so the required code is
customers += newCustomer;
This expands into
customers = customers + newCustomer;
The overloaded + operator is called for the right expression. This returns a `CustomerList`, which is then assigned through the = operator to `customers`.
Answer:
Intelligence
Explanation:
Intelligence is the product resulting from the collection, collation, evaluation, analysis, integration, and interpretation of collected information. It is a specialised information product that provides an adversary with information required to further its national interests. One of the most important functions of intelligence is the reduction of the ambiguity inherent in the observation of external activities.rations.
In most cases, the development of an intelligence product involves collecting information from a number of different sources. In some cases, information may be disseminated immediately upon collection based upon operational necessity and potential impact on current operations.
Strategic intelligence provides policy makers with the information needed to make national policy or decisions of long-lasting importance. Strategic intelligence collection often requires integrating information concerning politics, military affairs, economics, societal interactions, and technological developments. It typically evolves over a long period of time and results in the development of intelligence studies and estimates.
Operational intelligence is concerned with current or near-term events. It is used to determine the current and projected capability of a program or operation on an ongoing basis and does not result in long-term projections. Most intelligence activities support the development of operational intelligence.
Answer:
The code solution is written in Java.
- import java.util.Scanner;
-
- public class TestScore {
-
- public static void main(String[] args) {
-
- Scanner input = new Scanner(System.in);
-
- System.out.print("Please enter first score: ");
- double firstScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(firstScore));
-
- System.out.print("Please enter second score: ");
- double secondScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(secondScore));
-
- System.out.print("Please enter third score: ");
- double thirdScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(thirdScore));
-
- System.out.print("Please enter fourth score: ");
- double fourthScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(fourthScore));
-
- System.out.print("Please enter fifth score: ");
- double fifthScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(fifthScore));
-
- System.out.println("Average score: " + calcAverage(firstScore, secondScore, thirdScore, fourthScore, fifthScore));
-
- }
-
- public static double calcAverage(double score1, double score2, double score3, double score4, double score5){
- double average = (score1 + score2 + score3 + score4 + score5) / 5;
- return average;
- }
-
- public static String determineGrade(double score){
- if(score >= 90){
- return "A";
- }
- else if(score >= 80 ){
- return "B";
- }
- else if(score >=70){
- return "C";
- }
- else if(score >=60){
- return "D";
- }
- else{
- return "F";
- }
- }
- }
Explanation:
Firstly, create the method, <em>calcAverage()</em>, that takes five test scores. Within the method, calculate the average and return it as output. (Line 33 - 36)
Next, create another method, <em>determineGrade()</em>, which takes only one score and return the grade based on the range of the score. (Line 38 -54)
Once the two required methods are created, we are ready to prompt use for input five test scores using Java Scanner class. To use get user input, create a Scanner object (Line 7). Next, use getDouble() method to get an input score and assign it to variables firstScore, secondScore, thirdScore, fourthScore & fifthScore, respectively. Once a score input by user, call determineGrade() method by passing the input score as argument and immediately print out the return grade. (Line 9 - 27)
At last, call calcAverage() method by passing the first test score variables as argument and print out the returned average value. (Line 29).
