Question 1
Type: MCSA
Which of the following is considered a threat to information quality?
1. An unauthorized user hacks into the system to review the clients’ records
2. Not verifying information as correct prior to entry
3. An earthquake interrupts the power supply and causes data loss
4. A wireless transmission is intercepted to review a new client’s records.
Correct Answer: 2
Rationale 1: Hackers are a threat to confidentiality. The correct response is a failure to enter data correctly which is a very serious threat to the quality of information.
Rationale 2: Failing to enter data correctly is a very serious threat to the quality of information and “garbage in” equals “garbage out”. Interruption of a power supply is a threat to information availability; and hackers and wireless interceptions are threats to confidentiality.
Rationale 3: Interruption of a power supply is a threat to information availability. The correct response is a failure to enter data correctly which is a very serious threat to the quality of information.
Rationale 4: Wireless interception is a threat to confidentiality. The correct response is a failure to enter data correctly which is a very serious threat to the quality of information.
