ISQI ISTQB Certified Tester Advanced Level - Technical Test Analyst (V4.0) 認定 CTAL-TTA_Syll19_4.0 試験問題：

問題 #1
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?

A. Portability
B. Compatibility
C. Adaptability
D. Reliability

問題 #2
You are involved in testing a system in the medical domain. Testing needs to comply with the FDA requirements and is rated as being safety critical. A product risk assessment has been performed and various mitigation actions have been identified. Reliability testing is one of the test types that needs to be performed throughout the development lifecycle.
Based on the information provided, which of the following activities would need to be addressed in the test plan?

A. Design and execution of test cases for scalability.
B. Testing whether the installation/de-installation can be completed.
C. Design and execution of specific tests that evaluate the software's tolerance to faults in terms of handling unexpected input values.
D. Perform a vulnerability scan.

問題 #3
Subject to testing is a software system (COTS) for Project Administration and Control (PACS). PACS is a multi-project system for controlling the project time, e.g., in terms of scheduling and tracking, and managing the productivity of projects, e.g., in terms of effort and deliverables.
During various interviews with stakeholders the following information was gathered:
* Using PACS is not business critical. There is no impact such as high financial losses or problems to the operational continuity of an organization. Its application is not critical since the software package does not support directly the operational, or the primary, business processes of an organization. It supports (project) management in the project planning and tracking process. Of course, it will be highly annoying for users if the system "goes down" from time to time. Although this does not have a high impact for the business process as a whole, the Mean Time Between Failures (MTBF) still needs to be at a good level to be successful in the market.
* Users of PACS typically have an academic educational level, but have no prior experience with this particular type of project management software. The system will be used by a large number of users within an organization.
* The system will be used on a regular basis, e.g., several times per day by project managers and several times per week by project employees. This means that the system will not be used very intensively, often only for some data input or an information request. Its usage is not considered to be very time-critical.
* The data is recorded on-line and real-time. The system is expected to run in multiple hardware environments in various network environments. It is also expected that changes in the operational environments will happen in the upcoming period that also need to be supported.
Based on the information provided by the stakeholder, which combination of non-functional quality characteristics should you propose to test as part of your test approach?

A. Reliability and Performance efficiency
B. Performance efficiency and Portability
C. Security and Reliability
D. Reliability and Portability

問題 #4
At which test level would reliability testing most likely be performed?

A. Functional acceptance testing
B. Static testing
C. Component testing
D. System testing

問題 #5
A medical company has performed a safety criticality analysis using the IEC61508 standard. The software components to be developed have been categorized by Safety Integrity Level (SIL). Most components have been rated at SIL 1 or 2, and a few components at SIL 4.
After some discussions with the QA manager, the project has decided to adhere to the recommendations for test coverage provided by the IEC61508 standard.
Which level and type of test coverage should at least be used for the components rated at Safety Integrity Level (SIL) 2?

A. 100% statement coverage, 100% decision coverage and 100% multiple condition coverage
B. 100% statement coverage, 100% decision coverage and 100% MC/DC coverage
C. 100% statement coverage
D. 100% statement coverage and 100% decision coverage
