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?
What is MOST likely to be a consideration when implementing a new performance test tool?
Which of the following is a generic risk factor that should be considered by a Technical Test Analyst during a product risk analysis?
Your team is now accountable for the support and enhancement of a payroll system that has been in production for many years and modified by many different developers. It has been noticed by management that small functional enhancements take much longer than equivalent changes on more recently developed systems. You have been tasked with implementing improved testing approaches that will help to identify the root cause of this problem.
Which of the following is the best technique to apply in this scenario?
Within an embedded software project, the maintainability of the software is considered to be critical. It has been decided to use static analysis on each delivered software component.
Which of the following metrics is NOT a maintainability metric typically used with static analysis?
Considering the following statements:
A) The data used for a test is held external to the automated script
B) The scope of an automated test suite is driven by the range of test data available
C) It uses a high-level language to separate the action to be performed on the test data from the test script
D) A spreadsheet is used to record the actions to be performed instead of the input data
Which of the following options is the correct selection of these statements to describe data-driven and keyword-driven automation?
Which option describes a good practice when applying test automation for a Regression-averse test approach?
SELECT ONE OPTION
Consider the following fault attack:
• Force all possible incoming errors from the software/operating system interfaces to the application.
Which of the following is the kind of failure you are looking for when using this attack?
Which requirements engineering technique would BEST identify how different groups of users may interact with a system, helping to identify gaps and inconsistencies in a user story-’

The F in the mnemonic FIRST stands for Fast Which option correctly states the meanings of the other four letters (IRST)?
SELECT ONE OPTION
You need to implement a Java class that validates a password entry field. The validation critena states that the password must:
1. be a minimum of 8 characters
2 contain at least one special character.
You are focusing on validation criterion 1 and have written a test class that checks that a 7 character password entry will fail validation.
You have written code designed to make this test class pass, however, on first execution of the test class it has failed
What should you do next9

Which of the following is a common technical issue that can result in an automation project failing?
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?
Which of the following defect types is NOT an example of a defect type typically found with API testing?
A product risk assessment has revealed the following product risks:
• lack of usability requirements
• security during on-line transactions
• perceived performance of the system and response time from the user interface
• a required availability of almost 100%
To address the 4th risk, which of the following quality characteristics for technical testing should be part of the test approach?
Which statement correctly describes service virtualization’’
SELECT ONE OPTION
You are working on a project that is integrating code from multiple development groups. There have been numerous integration problems, particularly regarding reliability, error recovery and transactional integrity. You are now responsible for planning the performance efficiency testing for this product. There Is a strong feeling among the development managers that some parts of the code are weaker than others and will tend to exhibit problems during the performance efficiency testing. To identify these problematic areas as soon as possible, which type of testing should you do?
When conducting a data flow analysis of following section of pseudo code:
Declare Function_Biggest integer (inputl integer. Input2 Integer) }
Declare output Integer
Set output = inputl
If input2 > output then
Set output = input2
Endif
Return output
}
Which of the variables utilized above has a potential anomalie?
The stakeholders in a new system want its mean time between failure to be three months or longer, with a mean time to repair the system of ten minutes or less when it does fail. When planning and specifying reliability tests to be performed before release, which ONE of the following is a factor that must be considered?
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.
