Not sure what quizScore1-5 is, but here it is. Also, I'm not entirely sure what language you're working with here, but null can't be returned as an integer. If it were a string, for example, it'd be possible as string is an object reference type.
public int getData(int dataNumber)
{
if (dataNumber == 1)
return quizScore1;
else if (dataNumber == 2)
return quizScore2;
else if (dataNumber == 3)
return quizScore3;
else if (dataNumber == 4)
return quizScore4;
else if (dataNumber == 5)
return quizScore5;
else
return 0;
}
Answer:
D. Zero-day
Explanation:
It is clearly stated that the antivirus is still up-to-date on the workstation, and there has been no alterations to the firewall. Hence, this means the software is functional and up-to-date with all known viruses. This shows that this attack is unknown to the manufacturer of the antivirus software and hence no virus definition or patch fixing this problem has been developed yet. In this light, it is a zero-day.
A zero-day is a type of vulnerability in a software that is not yet known to the vendor or manufacturer, hence this security hole makes the software vulnerable to attackers or hacker before it is been fixed.
