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 key stakeholders are:

The Merchandising Manager, who wants parameter entry to be quick and easy.

The Data Centre Manager, who requires the new batch jobs to take less time than the old ones.

No specific performance requirements have been given, either for the batch jobs or for online parameter entry.

Which TWO of the following will BEST meet the objectives of the stakeholders?

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.

You are responsible for the non-functional testing of a website supporting a popular restaurant chain. Due to the rapid expansion of the number of restaurants in the chain, the company is expecting the peak number of concurrent website views to more than triple in the next 6 months. As a result, it has purchased two further production servers to support the existing one. A new hardware release has been scheduled for which the following product risk has been recorded:

{Insert Table 2)

Which one of the following non-functional test typos would be BEST to mitigate this risk?

You work for a small supermarket chain which has successfully operated a product inventory application for several years. It has recently purchased a data warehousing solution which provides tailorable profiling of product purchases with the aim of improving its marketing strategy. The decision has been made to host the data warehousing software and database on the same server used by the product inventory application. Based on this decision, two product risks have been cataloged:

The co-existence of both applications on the same server may introduce resource conflicts, resulting in an unacceptable impact on the functionality of the product inventory application

In the event of loss or corruption of product inventory data during transfer to the warehouse, it may not be possible to restore from back-up in the timeframe required, resulting in lost business.

Which TWO non-functional test types should be included in the test plan to mitigate both product risks?
