Question 3
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.

Question 5
The following epic has been written:
As a vehicle driver
I want to find an available space In a car park
So that I can pay in advance to reserve that space
This epic will be used to develop user stories for a new National Car Parking application Both public and private car park owners will be able to utilise the system, allowing drivers of all kinds to guarantee an available car parking space on arrival at their chosen car park, according to the kind of vehicle that they may drive There will be multiple stakeholders including different car park owners, different user groups including disabled drivers and different vehicle types such as car. van and motorbike.
From this epic, multiple user stories will be written. The following acceptance criteria have been written for the epic, and will be applicable to all user stories (each user story will also have its own acceptance cntena):
1.End-to-end response time for any individual request submitted by a user must not exceed 5 seconds
2.All correspondence with stakeholders must be via email and text message
3.The application must be accessible on most mobile technology
4.A user cannot submit a form unless all mandatory fields are entered
5.Payment method can be made using the most popular electronic options
Applying the INVEST technique to this epic, including its acceptance criteria, which of the following statements is correct?

Question 6
You are an experienced tester on an Agile team that is producing a new application. The product backlog has been refined sufficiently to begin development for the first release. This stories in this backlog contain a mixture of functional and non-functional requirements, as well as some technical stories that will provide elements of the application's infrastructure The developers have decided to use TDD as a deveiopment approach but automation of the acceptance tests is not yet planned.
You have been asked to recommend whether or not the team should take an atdd approach as well as TDD.
what would be the BEST recommendation in these circumstances?

Question 7
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

Question 13
Within the world of consumer electronics, the amount of embedded software is growing rapidly. The amount of software in high-end television sets has increased by a factor of about eight over the last six years. In addition, the market of consumer electronics has been faced with a 5 -10% price erosion per year. The price of a product is, among a number of other things, determined by the microcontroller used. Therefore, the use of ROM and RAM remains under high pressure in consumer electronic products, leading to severe restrictions on code size.
