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

1. Consider the code fragment provided below:

The comment frequency of the code fragment is 13%.
To which non-functional quality characteristic does a good level of comment frequency especially contribute?

A) Usability
B) Portability
C) Performance Efficiency
D) Maintainability

2. Consider the following specification:

If you are flying with an economy ticket, there is a possibility that you may get upgraded to business class, especially if you hold a gold card in the airline's frequent flier program. If you don't hold a gold card, there is a possibility that you will get 'bumped' off the flight if it is full when you check in late.
This is shown in the control flow graph below. Note that each box (i.e., statement, decision) has been numbered.
Three tests have been run:
Test 1: Gold card holder who gets upgraded to business class
Test 2: Non-gold card holder who stays in economy
Test 3: A person who is bumped from the flight
What is the level of decision coverage achieved by these three tests?

A) 75%
B) 60%
C) 80%
D) 67%

3. Consider the code fragment provided below:

How many test cases are needed for the code fragment lines 26 - 37 to achieve 100% modified condition/decision coverage?

A) 6 test cases
B) 8 test cases
C) 4 test cases
D) 2 test cases

4. As a technical test analyst, you are involved in a risk analysis session using the Failure Mode and Effect Analysis technique. You are calculating risk priorities. Which of the following are the major factors in this exercise?

A) Financial damage, frequency of use and external visibility
B) Severity and priority
C) Functionality, reliability, usability, maintainability, efficiency and portability
D) Likelihood and impact

5. 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 Portability
B) Security and Reliability
C) Reliability and Performance efficiency
D) Performance efficiency and Portability
