Given the following pseudocode:
Program tax check
BEGIN
yearly := 0
tax := 0
get (monthly)
get (tax_rate)
for I = 1..12 loop
yearly := yearly + monthly
tax := tax - (tax_rate * monthly)
ENDLOOP
salary := monthly * 12
IF salary = yearly THEN
print ("Salary OK")
ELSE
print ("Salary not OK")
ENDIF
year_tax := salary * tax_rate
IF year_tax = tax THEN
print ("Tax Problem")
ENDIF
END tax check
If control flow analysis is performed on the pseudocode, which of the following results is MOST likely?

• A. No unreachable code
• B. Unreachable code at lines 15 and 19
• C. Unreachable code at line 19
• D. Unreachable code at line 15

A project to replace your company's sales and merchandising system has begun. The old system is still in production but is poorly documented and expensive to maintain: changing it has often produced a large quantity of defects. The new version will be developed using modern techniques and technology.
Requirements include:
* Loading sales data, sent electronically from the stores each evening, into a central database where it is then available for other applications.
* Producing sales reports for the merchandisers, whose job is to manage stock levels in stores.
* Predictions of future demand for each product, based on a combination of sales history and forecasting parameters.
Requirements 1 and 2 are satisfied by the existing system and will be rewritten with no significant changes.
Requirement 3 is new: these forecasting reports will be run overnight, and users will request them by entering simple parameters online during the day.
The sales data are loaded in an overnight batch run. There have been problems at peak periods when this run has taken longer than scheduled, so that dependent jobs could not finish before the start of the working day.
As a Technical Test Analyst, you have been asked to contribute to the project's Master Test Plan. The concerns expressed by stakeholders during risk identification include the length of the batch job runs, ease of parameter entry for the users, unauthorized access to stored sales data, and limited time for testing. With these in mind, which TWO of the following quality characteristics sub-characteristics are likely to contain the highest levels of technical risk?
A) Operability.
B) Time behavior.
C) Interoperability.
D) Security.
E) Testability.

• A. c and e
• B. b and e
• C. b and d
• D. a and b

Below is the pseudo-code for the bingo program:

The bingo program contains a data flow anomaly. Which data flow anomaly can be found in this program?

• A. The hard-coded value '2" should not be used.
• B. An invalid value is assigned to variable "B".
• C. Variable "AB is defined but subsequently not used.
• D. Variable "MIN" is not assigned a value before using it.

The requirements specification of a product begins with this sentence:
"The xyz system will provide many new user functions. These must be easy for our operators to use and tolerant of user input errors. These new functions must also be easy to learn. Because of very high transaction rates and limited processing power, the software design must be very efficient. The system must be available as close to 24x7 as possible.
Which three ISO 25010 major quality characteristics should be tested for possible defects with this implementation?

• A. Stability, security, accessibility
• B. Reliability, usability, performance efficiency
• C. Functional suitability, interoperability, learnability
• D. Usability, fault tolerance, operability
