Answer:
(i) C is increased (S, B same)
Explanation:
Cache are items which are stored in the computer at a hidden place. These are sometimes unwanted and they may hinder the speed and performance of the device. They exist to bridge speed gap.
Your IaaS cloud company has announced that there will be a brief outage for regularly scheduled maintenance over the weekend to apply a critical hotfix to vital infrastructure. What are the systems they may be applying patches to
Answer: Load Balancer
Hypervisor
Router
Explanation:
The systems that they may be applying the patches to include load balancer, hypervisor and router.
The load balancer will help in the distribution of a set of tasks over the resources, in order to boost efficiency with regards to processing.
A hypervisor is used for the creation and the running of virtual machines. The router helps in the connection of the computers and the other devices to the Internet.
The _________ attack exploits the common use of a modular exponentiation algorithm in RSA encryption and decryption, but can be adapted to work with any implementation that does not run in fixed time.
A. mathematical.
B. timing.
C. chosen ciphertext.
D. brute-force.
Answer:
chosen ciphertext
Explanation:
Chosen ciphertext attack is a scenario in which the attacker has the ability to choose ciphertexts C i and to view their corresponding decryptions – plaintexts P i . It is essentially the same scenario as a chosen plaintext attack but applied to a decryption function, instead of the encryption function.
Cyber attack usually associated with obtaining decryption keys that do not run in fixed time is called the chosen ciphertext attack.
Theae kind of attack is usually performed through gathering of decryption codes or key which are associated to certain cipher texts The attacker would then use the gathered patterns and information to obtain the decryption key to the selected or chosen ciphertext.Hence, chosen ciphertext attempts the use of modular exponentiation.

Write a method that prints on the screen a message stating whether 2 circles touch each other, do not touch each other or intersect. The method accepts the coordinates of the center of the first circle and its radius, and the coordinates of the center of the second circle and its radius.
The header of the method is as follows:
public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2)
Hint:
Distance between centers C1 and C2 is calculated as follows:
d = Math.sqrt((x1 - x2)2 + (y1 - y2)2).
There are three conditions that arise:
1. If d == r1 + r2
Circles touch each other.
2. If d > r1 + r2
Circles do not touch each other.
3. If d < r1 + r2
Circles intersect.
Answer:
The method is as follows:
public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){
double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));
if(d == r1 + r2){
System.out.print("The circles touch each other"); }
else if(d > r1 + r2){
System.out.print("The circles do not touch each other"); }
else{
System.out.print("The circles intersect"); }
}
Explanation:
This defines the method
public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){
This calculate the distance
double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));
If the distance equals the sum of both radii, then the circles touch one another
if(d == r1 + r2){
System.out.print("The circles touch each other"); }
If the distance is greater than the sum of both radii, then the circles do not touch one another
else if(d > r1 + r2){
System.out.print("The circles do not touch each other"); }
If the distance is less than the sum of both radii, then the circles intersect
else{
System.out.print("The circles intersect"); }
}

Reverse Word Order: Write a program that reverses the order of the words in a given sentence. This program requires reversing the order of the words wherein the first and last words are swapped, followed by swapping the second word with the second to last word, followed by swapping the third word and the third to last words, and so on.
Answer:
function reverseArray(arr) {
if (arr.length > 1) {
arr = [arr[arr.length-1], ...reverseArray(arr.slice(1, -1)), arr[0]]
}
return arr;
}
function reverseSentence(sentence) {
let words = reverseArray( sentence.split(" ") );
return words.join(" ");
}
console.log( reverseSentence("The quick brown fox jumps over the lazy dog's back") );
console.log( reverseSentence("one two three") );
console.log( reverseSentence("one two") );
console.log( reverseSentence("Single") );
