Answer:
B. Malware
Explanation:
Malware is general to most harmful programs on a computer, as Adware is a potentially unwanted program that is designed to advertise other programs or services. And ransomware is a program that will encrypt important user files such as; documents, pictures, and videos. Spyware is a program that is designed to spy on users, examples are; using your camera without your consent, key-loggers, and taking screenshots of our desktop. Thus i believe it is malware because the question covers multiple categories.
 
        
             
        
        
        
Answer:
Addresses.
Explanation:
An argument can be defined as a value that can be passed to a function. 
Simply stated, an argument is a value that must be passed into a function, subroutine or procedure when it is called. This value can be passed to a function either by reference or by value.
This ultimately implies that, an argument which is also a parameter variable stores information which is passed from the location of the method call directly to the method that is called by the program.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
When calling a function with arguments that should be modified, the addresses of those arguments are passed. This is simply because the argument is an address or pointer in itself and as such the function parameter being called must be a pointer.
In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.
Hence, all instance variables that have been used or declared in any superclass would be present in its subclass object.
 
        
             
        
        
        
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:
Interoperability is the ability of or degree to which two or more systems usefully exchange information via interfaces in particular context. Interoperability can be defined in two ways which includes the ability to exchange data (syntactic interoperability) and also the ability to correctly interpret the data being exchanged (semantic interoperability).
If two systems failed to exchange information properly, it means they are not clear to interpret and not easy to communicate and get proper information from each other and that might result in a failed communication which is in turn result in security flaw. 
Other quality attributes strongly related (at least potentially) to interoperability is Application Programming Interface (API)
API is a software intermediary that allows two applications to communicate to each other and are necessary for systems interoperability.
