Answer:
A and C
Explanation:
Option A:
In IPv6 there is a rule to reduce an IPv6 address when there are two or more consecutive segments of zeros just one time. This rule says that you can change the consecutive zeros for “::”
Here is an example
How to reduce the following IPv6 address?
ff02:0000:0000:0000:0000:0000:0000:d500
Ans: ff02::d500
Example 2:
2001:ed02:0000:0000:cf14:0000:0000:de95
Incorrect Answer -> 2001:ed02::cf14::de95
Since the rule says that you can apply “::” just one time, you need to do it for a per of zero segments, so the correct answer is:
Correct Answer -> 2001:ed02::cf14:0:0:de95
Or
2001:ed02:0:0:cf14::de95
Option C:
Since in IPv6 there are 
available addresses which means 340.282.366.920.938.463.463.374.607.431.768.211.456 (too many addresses), there is no need of NAT solution, so each device can have its own IP address by the same interface to have access through the internet if needed. If not, you can block the access through internet by the firewall.
Answer:
Option E i.e., transparency is the correct option.
Explanation:
When any person using social media networks the he always ensure that he gives all the information related accurately about himself because in the social media network there is the transparency of everything except his chat with other but any person get details of the other person only if he is using social media network.
Answer:
#include <bits/stdc++.h>
using namespace std;
int main() {
string in;//string in for taking input...
cout<<"Do you want to continue ?"<<endl;
getline(cin,in);//taking input from the user...
if(in=="y"||in=="Y"||in=="yes"||in=="OK"||in=="Why not?")//conditions..
cout<<"OK"<<endl;
else if(in=="No")
cout<<"terminating"<<endl;
else
cout<<"Bad input"<<endl;
return 0;
}
Explanation:
I have taken a string in.
Then taking input from user.
Checking the conditions using if else if ladder.
