CTAL-TTA Practice Questions

The last release of a hotel booking website resulted in poor system performance when hotel searches reached peak volumes. To address these problems in the forthcoming release, changes to the system architecture are to be implemented as follows:

Change 1 - Provision of a single Internet service using multiple servers, rather than a single server, to maximize throughput and minimize response time during peak volumes

Change 2 - Prevention of unnecessary database calls for objects that were not immediately needed by the calling applications. Achieved by not automatically creating database connections at the start of processing, instead only just before the data is required.

The system architecture document has been drafted and as Technical Test Analyst you have been invited to participate in its review. Which of the following review checklist items is MOST likely to identify any defects in the proposed system architecture for Change 1?

There are multiple activities the Technical Test Analyst performs regarding test automation. Which of the following activities is a typical test automation activity that the Technical Test Analyst will perform?

Which statement is correct with respect to fault injection tools?

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?

You have conducted static analysis on several new modules for an existing product. You are now executing test cases and are seeing inconsistent problems including crashes. Intermittent error messages are appearing. Despite all your best efforts, you are not able to find reproducible scenarios to force these errors.

What problem in the code are you likely seeing?

Which of the following statements best captures the difference between data-driven and keyword-driven test automation?

You are defining the test approach for an Agile project developing a system to control traffic lights at busy road junctions. The system will use sensors to measure traffic density and flow rates, optimizing traffic flow. While safety-critical, a risk assessment has deemed the project's risk level as low due to the team's expertise.

Which option below represents the BEST test approach for this project?

An enhancement to a Social Media application allows for the creation of new Groups. Any number of existing application members can be added to a Group. An attempt to add a non-existing member of the application to a Group will result in an error. Members can also be removed from an existing Group. Existing Groups can also be deleted but only if there are no current members attached to it.

Which keyword-driven input table provides an adequate test of this enhancement?

Given the following code:

If x > y and z = 3 statement!

elseif z = 4 statement

endif;

What is the minimum number of tests needed to achieve 100% decision coverage?
