Answer:
Option (A) A successful WPS attack has occurred
Explanation:
- WPS stands for Wi-Fi Protected Setup.
- Its a network security protocol in the Wi-Fi which has a vulnerability.
- The connection to the Wi-Fi can be established through the router in four ways. They are
- (a) PIN method
- (b) Push button method
- (c) Near field communication method
- (d) USB Method.
- Out of all the modes to be connected to the network, the PIN method has a flaw in it.
- In this PIN method, an attacker can brute force the PIN (guessing the PIN by some techniques) and gain unauthorized access to the network.
- In the given case in the question, the network administrator finds that multiple unauthorized devices has gained access to the network.
- Option (A) is correct.
- Option (B) ARP Poisoning, (C) botnet and (D) Evil Twin attack are different and so are the wrong options.
Answer:
Option 2: a type of mini chart that users can insert into a worksheet
Explanation:
A graph or chart is used to show trends and changes in a dataset.
When we have to show trends or changes in MS Excel, there are a lot of options available. One of them is Sparklines. Sparklines are like mini charts that can be used to show data graphically.
Hence,
The correct answer is:
Option 2: a type of mini chart that users can insert into a worksheet
Answer:
CREATE FUNCTION exam_eligible_students
RETURN NUMBER AS
num_students NUMBER(15);
BEGIN
SELECT COUNT(STUDENT_ID)
INTO num_students
FROM STUDENT_ATTENDANCE
WHERE ELIGIBILITY_FOR_EXAMS = 'Y';
RETURN (num_students);
END;
Explanation:
exam_eligible_students is a made of name for the FUNCTION to be called.
num_students is a made up name for the RETURN to be called. The RETURN name is referenced in the INTO statement and as the name of the the return in the RETURN line in ().
Answer:
A: Radio waves.
Explanation:
Computers use short-wave radio in order to communicate with devices in it's immediate vicinity.
The statement which best explains how algorithms running on a computer can be used to solve problems is; D. Some problems cannot be solved by an algorithm.
<h3>What is an algorithm?</h3>
An algorithm is simply a standard formula or procedures which is made up of a set of finite steps and instructions that must be executed on a computer, so as to proffer solutions to a problem or solve a problem under appropriate conditions.
However, it should be noted that it is not all problems that can be solved by an algorithm, especially because the required parameters and appropriate conditions are not feasible or met.
