Below is pseudo-code which calculates a customer's cruise credits based on past cruise history:
PROGRAM CALC CRUISE CREDITS (CUST_ID)
COUNT_CRUISES, CRUISE_CREDITS, LOYALTY_RATING: INTEGER
CRUISE_LENGTH, CRUISE_ACCOM_TYPE: VAR
LOYALTY_RATING = 0
COUNT_CRUISES = 0
CRUISE_LENGTH = 0
CRUISE_ACCOM_TYPE = 0
BEGIN
READ CUSTOMER'S CRUISE HISTORY TO OBTAIN COUNT OF CRUISES
READ CRUISE_HISTORY (CUST_ID)
WHILE COUNT_CRUISES != -1 DO
READ CUSTOMER'S NEXT CRUISE
READ NEXT_CRUISE
IF CRUISE_ACCOM_TYPE = 3 THEN
CRUISE_CREDITS = CRUISE_CREDITS + 5
ELSE
IF CRUISE_ACCOM_TYPE = 2 THEN
CRUISE_CREDITS = CRUISE_CREDITS + 3
ELSE
CRUISE_CREDITS = CRUISE_CREDITS + 2
ENDIF
ENDIF
COUNT_CRUISES = COUNT_CRUISES - 1
ENDWHILE
LOYALTY_RATING = CRUISE_CREDITS / COUNT_CRUISES
WRITE ("CRUISE CREDIT TOTAL IS:")
WRITE (CRUISE_CREDITS)
END PROGRAM CALC CRUISE CREDITS
The variable Cruise_Length (line 3) results in which type of data flow anomaly?

• A. Killed before being Defined
• B. Defined but not Used
• C. Declared but not Defined
• D. Defined twice before Use

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 d
• C. a and b
• D. b and e

Consider the following section of pseudo code and associated test Input data:
If withdrawal-amount <= amount-on-deposit then Set authorize-transaction = true Else If withdrawal-amount <= S100 AND preferred-customer = true then Set authorize-transaction = true Else Set authorize-transaction = false Endif Endif Input data set #1 withdrawal-amount = 160 amount-on-deposit = 100 preferred-customer = true Input data set #2 withdrawal-amount = 500 amount-on-deposit = 500 preferred-customer = false Input data set #3 withdrawal-amount = 50 amount-on-deposit = 500 preferred-customer = false What would be the decision coverage achieved if each of these test input data sets were run once?

• A. 0%
• B. 33%
• C. 100%
• D. 50%

Which of the following is a valid reason for including security testing in a test approach?

• A. To provide measurements from which an overall level of availability can be obtained.
• B. To evaluate the ability of a system to handle peak loads at or beyond the limits of its anticipated or specified workloads
• C. There is a threat of unauthorized copying of applications or data.
• D. Software changes will be frequent after it enters production.

Consider the pseudo code for the Answer program:

Which of the following statements about the Answer program BEST describes the control flow anomalies to be found in the program?

• A. The Answer program contains an infinite loop.
• B. The Answer program contains unreachable code and an infinite loop.
• C. The Answer program contains unreachable code.
• D. The Answer program contains no control flow anomalies.
