A recent antivirus scan on a server detected a Trojan. A technician removed the Trojan, but a security administrator expressed concern that unauthorized personnel might be able to access data on the server. The security administrator decided to check the server further. Of the following choices, what is the administrator MOST likely looking for on this server?
a. Trojan
b. spyware
c. adware
d. ransomware
Answer:
B. Spyware
Explanation:
Spywares are silent software that steals sensitive information such as internet or company data, and other similar information. They are oftentimes unnoticed and supply stolen data to external users, data centers or advertisement companies.
Sophisticated spyware can go as far as installing software to manipulate your settings or use passwords on your behalf.
Even though the Trojan was detected in our scenario, The Trojan would have created a backdoor to allow spyware in. This spyware will not be easily noticed by the technician or the antivirus, however, it could be more devastating than the Trojan.
That is why the security administration expresses concern over a breach despite the removal of the Trojan.
Suppose the beta of Microsoft is 1.13, the risk-free rate is 3 percent, and the market risk premium is 8 percent. Calculate the expected return for Microsoft.
Answer:
8.65%
Explanation:
Rj = Rf + risk premium.
Rj = Rf + β[E(RM − Rf)].
= 3 + 1.13 (8 - 3)
= 3 + 1.13 x 5
= 3 + 5.65
= 8.65 percent
This relationship between risk and expected return is called the security market line.
The expected return for Microsoft, using CAPM and the given risk-free rate, beta, and market risk premium, is 12.04 percent.
To calculate the expected return for Microsoft, given that the beta of Microsoft is 1.13, the risk-free rate is 3 percent, and the market risk premium is 8 percent, we can use the Capital Asset Pricing Model (CAPM). The CAPM formula is:
Expected Return = Risk-Free Rate + (Beta Times Market Risk Premium)
Plugging in the given values:
Expected Return = 3% + (1.13 Times 8%)
Expected Return = 3% + 9.04%
Expected Return = 12.04%%
Therefore, the expected return for Microsoft is 12.04% percent.

Anita likely will be able to retain this information in short-term memory, without additional processing, for:_________.a. a second or lessb. 30 seconds or lessc. about two minutesd. a maximum of five minutes
Answer:
Option B; 30 SECONDS OR LESS.
Explanation:
Short-term memory, also known as primary or active memory, is the information we are currently aware of or thinking about.
When short-term memories are not rehearsed or actively maintained, they last mere seconds.
Most of the information kept in short-term memory will be stored for less than 30 seconds (approximately 20 to 30 seconds), but it can be just seconds if rehearsal or active maintenance of the information is not done.
Therefore, Anita likely will be able to retain the information in short-term memory, without additional processing, for 30 SECONDS OR LESS.

Write a statement that declares a PrintWriter reference variable named output and initializes it to a reference to a newly created PrintWriter object associated with a file named "output.txt".
Answer:
PrintWriter variable = new PrintWriter("output.txt");
Explanation:
There are two ways of declaring a reference variable in programming.
One way is
Reference Variable-name = new Reference ("some texts here");
While the other is
Reference Variable-name;
Variable-name = new Reference ("some texts here");
Both ways are valid ways of reference variable declaration.
In the question above, the reference is PrintWriter, it points to output.txt and the question says "write a single statement";
Hence, we make use of
PrintWriter variable = new PrintWriter("output.txt");
A reference variable is declared to be of a specific type and that type can never be changed.
