Question 1

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 code contains data flow anomalies on lines 14 and 27. Which examples of data flow anomalies can be found on these lines?

Options :

A :

Line 14: Cruise_Credits is not assigned a value (defined) before being used Line 27: Loyalty_Rating is defined but not subsequently used

B :

Line 14: Cruise_Credits is defined but not subsequently used Line 27: Loyalty_Rating is not assigned a value (defined) before being used

C :

Line 14: Cruise_Credits is re-defined before being used Line 27: Loyalty_Rating is defined but not subsequently used

D :

Line 14: Cruise_Credits should not be declared as an integer Line 27: Loyalty_Rating should be calculated within the While loop

Answer: C

Question 2

If you are flying with an economy ticket, there is a possibility that you may get upgraded to business class,

especially if you hold a gold card in the airline’s frequent flier program. If you don’t hold a gold card, there is

a possibility that you will get ‘bumped’ off the flight if it is full and you check in late. This is shown in the

figure hereafter. Note that each box (i.e. statement) has been numbered.

Three tests have been run:

Test 1: Gold card holder who gets upgraded to business class

Test 2: Non-gold card holder who stays in economy

Test 3: A person who is bumped from the flight

What is the statement coverage of these three tests?

Options :

A : 60%

B : 70%

C : 80%

D : 90%

Answer: C

Question 3

A component has been analysed during a risk-assessment and rated as highly critical. Which of the following white-box test techniques provides the highest level of coverage and could therefore be used to test this component?

B : Statement testing

C : Multiple condition testing

Options :

A : Load testing

B : Adaptability testing

C : Scalability testing

D : Reliability testing

Answer: C
