Answer:
 a. 118.20.210.254
Explanation:
Here are the few characteristics of Class A:
First bit of the first octet of class A is 0.
This class has 8 bits for network and 24 bits for hosts.
The default sub-net mask for class A IP address is 255.0.0.0 
Lets see if the first bit of first octet of 118.20.210.254 address is 0.
118 in binary (8 bits) can be represented as : 1110110
To complete 8 bits add a 0 to the left. 
01110110
First bit of the first octet of class A is 0 So this is class A address. 
For option b the first octet is : 183 in the form of bits = 10110111 So it is not class A address
For option c the first octet is 215 in the form of bits = 11010111 So it is not class A address
For option d the first octet is 255 in the form of bits = 11111111. The first bit of first octet is not 0 so it is also not class A address.
 
        
             
        
        
        
Answer:
The answer is "Confidentiality"
Explanation:
Confidentiality alludes to shielding data from being gotten to by unapproved parties. All in all, solitary the individuals who are approved to do so can access delicate information. Imagine your bank records, You ought to have the option to get to them obviously, and representatives at the bank who are assisting you with an exchange ought to have the option to get to them, yet nobody else ought to. An inability to keep up Confidentiality implies that somebody who shouldn't have access has figured out how to get it, through deliberate act or coincidentally. Such a disappointment of Confidentiality, normally known as a breach  can't be helped. When the secret has been uncovered, it is highly unlikely to un-uncover it. 
Assuming your bank records are posted on a public site, everybody can realize your bank account number, balance, and so forth, and that data can't be eradicated from their brains, papers, PCs, and different spots. Virtually all the significant security occurrences reported in the media today include loss of Confidentiality. 
Thus, in summary, a breach of Confidentiality implies that somebody accesses data who shouldn't be permitted to.
 
        
             
        
        
        
Answer:Deployment diagram
Explanation: Deployment diagram is the diagram that is used for displaying the hardware parts upon which the software architecture works.The main purpose of the diagram is showing the function and operations taking place through the deployment of the software system with the hardware.
These diagrams are made up of the nodes , interface, artifacts and other components. Other given options are incorrect because architectural diagram is for designing of the architecture of a system,sequence diagram is used for the sequential order display of system components and  state chart diagram is the diagram that shows the status of the parts of the operating system.
Therefore, the correct option is deployment diagram.
