Answer: ....
If one load balancer fails, the secondary picks up the failure and becomes active. They have a heartbeat link between them that monitors status. If all load balancers fail (or are accidentally misconfigured), servers down-stream are knocked offline until the problem is resolved, or you manually route around them.
Explanation:
Load balancing is a technique of distributing your requests over a network when your server is maxing out the CPU or disk or database IO rate. The objective of load balancing is optimizing resource use and minimizing response time, thereby avoiding overburden of any one of the resources.
The goal of failover is the ability to continue the work of a particular network component or the whole server, by another, should the first one fail. Failover allows you to perform maintenance of individual servers or nodes, without any interruption of your services.
It is important to note that load balancing and failover systems may not be the same, but they go hand in hand in helping you achieve high availability.
Answer:
Repetition, and regular rhythm
Explanation:
Its certainly repetition method, and repetition method is of three types which are repetition, pattern and rhythm.
Remember repetition can be boring at times as we need to read same thing again and again. However, repetition sometimes can be good like the one we are referring to, and the other one can be like placing the logo or menu at same place in all web page. And its since it creates a habit in us for reading the web pages, And hence we can understand faster, and it looks please to our eyes hence as well.

Answer:
The answer to this question can be given as:
code:
class CollegeCourse
{
String Dept;
int CourseNumber;
double Credits;
double fee;
}
Explanation:
We all know that class is a collection of data members and member functions. In the above code we use the following syntax for class declaration that can be given as:
Syntax of class declaration :
class class_name
{
data member & member function
}
In the above code firstly we declare a class that is CollegeCourse. In this class, we define a variable that name and datatype is already given in the question that is String Dept, int CourseNumber, double Credits, double fee. In the variables first variable data type is string. It is used for store string value like ('us','xxx','aaa').The second variable datatype is an integer. It is used for store integer value like (1,23,5,56). The third and fourth variable datatype is the same that is double. This data type is used to store the floating-point value.
