Question No : 1
Which of the following is true about a browser-based application?

• A.It is designed to exercise capabilities of a particular device
• B.It runs on the device
• C.It is portable to any device that can run the supported browser
• D.It is generally faster than a native application

答えを確認する

正解:
Explanation:
C is correct. Since the application is running through the browser, if devices supports that browser it should work on the device.
This makes the application very portable.
A and B are characteristics of native applications.
D is incorrect because native applications are generally faster.

Question No : 2
In what way might a mobile device itself supply data to the mobile application?

• A.By providing location information by using its geolocation capability
• B.By gathering input from the user
• C.By communicating with a backend system
• D.By connecting to another device

答えを確認する

正解:
Explanation:
A is correct since this information is coming from the device itself.
B, C, and D all get the information from a source other than the device.

Question No : 3
Which of the following is a generic tool that would be useful for a mobile application testing project?

• A.A Simulator
• B.An emulator
• C.A defect tracking system
• D.A performance testing tool

答えを確認する

正解:
Explanation:
C is correct. This is a generic testing tool that would still be useful in a mobile application project.
A and B are specific tools that would be designed for use for the specific project.
D might work but most generic performance testing tools don’t work well for mobile applications because of their inability to work with simulators and provide the variability in network connections.

Question No : 4
If a tool is able to simulate the way in which a specific device would respond to an application, it is considered to be what type of simulator?

• A.A hybrid simulator
• B.A native device simulator
• C.A web-based application simulator
• D.A browsed-based application simulator

答えを確認する

正解:
Explanation:
B is correct.
The other three are referring to application types rather than devices.

Question No : 5

Question No : 6
Which of the following is a requirement for portability testing for the future of a mobile application?

• A.Knowing how the application works today with today’s devices
• B.Anticipating which devices will be popular and how they will be used
• C.Predicting how personas will change
• D.Creating new devices via emulators and testing the application on those emulators

答えを確認する

正解:
Explanation:
B is correct.
A is only helpful for today, not the future.
C might help to understand future usage, but won’t tell you which devices will be popular.
D would be a lot of work and the accuracy would depend on your creativity and ability to predict the future.

Question No : 7
You have been doing your mobile application performance testing on a simulator.
Why would you need to do some testing on a real device?

• A.Because a simulator is not an exact replica of the real device and may give different performance results.
• B.Because it is not possible to thoroughly test a simulator to ensure it is working correctly.
• C.Because simulators cannot be cloned to provide enough devices to generate a realistic load
• D.Because simulators cannot run concurrent applications

答えを確認する

正解:
Explanation:
A is correct.
A simulator is not a real device and doesn’t have the hardware and connectivity characteristics that the real device has.
B is not correct because you can thoroughly test a simulator, but that still won’t get around the problem in A.
C is not correct because this is precisely why simulators are used C they are easily cloned.
D is not correct because simulators can certainly run concurrent applications

Question No : 8
If you are testing how much battery is being used by your application, what are you testing?

• A.Task completion
• B.Delays
• C.User interface delays
• D.Resource usage

正解:

Question No : 9
You are planning to conduct performance testing on a new application. You have been given a set of personas to use during this testing.
How should you apply the personas in the performance testing approach?

• A.Personas should be duplicated by the automated tools to create virtual users who can create a realistic load on the system.
• B.Personas should be reviewed to understand the individual tasks being performed.
• C.Personas are used primarily for usability testing and should not be used as guidelines for performance testing.
• D.Personas should be used to derive use cases which can be broken down into user stories and then scripted into performance test scripts.

答えを確認する

正解:
Explanation:
A is correct. Personas represent realistic users doing realistic transactions and so are well suited for use in performance testing.
B is not correct because transactions are needed for performance testing rather than tasks.
C is not correct because while personas are used for usability testing, they are also used for performance testing.
D is not correct because user stories cover small bits of functionality, not transactions.

Question No : 10
Your company has created an application for doing crossword puzzles. The target users are in the age class of over 65 years old. There has already been considerable concentration on creating screens that are easy to navigate and intuitive. It is a primary goal that the software be easy to use. View ability has been implemented with a revolutionary magnification ability based on moving a magnifying glass across the screen. The beta testers have still had problems using the application, particularly when trying to enter the letters into the squares.
Given this information, which area should you target for more complete testing?

• A.Simplicity
• B.Layout
• C.Intuitiveness
• D.Navigation

答えを確認する

正解:
Explanation:
B is correct since the users seem to be having problems accessing either the pointer or the keyboard to enter the letters.
A and C seem to not be issues at this time since it is not an issue with understanding the application.
D may be an issue depending on how the user gets to the various input methods, but that is not indicated in the information here.

Question No : 11
You have information from production that the previous version of your product has had a high rate of abandonment after the initial download. In fact, it appears people download the application and never use it. Poor performance is thought to be the main problem that is causing people to give up the application.
Which of the following aspects of the application should be specifically targeted for testing to help determine if this is really the problem?

• A.User interface delays
• B.Irregular performance
• C.Resource usage
• D.Application launch time

答えを確認する

正解:
Explanation:
D is correct since it appears that people download it and never use it, perhaps because it takes so long to complete the download and the initial launch. This may not be the real problem, but it is certainly the first area to look at during testing. A and B are incorrect because the users are not actually using the software and wouldn’t see these issues. C might be a problem leading to D being a symptom.

Question No : 12
What is the primary use of teststorming?

• A.Load and stress testing from multiple locations
• B.Testing the device’s ability to deal with weather conditions
• C.Deriving test cases and test scenarios
• D.creating masses of test data

Question No : 13
If your application can only be used within a specific country, what feature of the device might be used to supply information that the application can use to make this determination?

• A.Geolocation
• B.Telephony
• C.Magnetometer
• D.Altimeter

答えを確認する

正解:
Explanation:
A is correct. Geolocation can pinpoint the location of the device and determine if it is in the correct country for the application to work. Without geolocation, the location might have to be determined by IP address or triangulation on a cellular network. Telephony could be used, but only if the telephone is involved in the application and we don’t know that from the question.

Question No : 14
Which of the following types of testing might consider the user’s age?

• A.Scenario-based testing
• B.Use case testing
• C.User story testing
• D.Persona-based testing

答えを確認する

正解:
Explanation:
D is correct. An age class user is a realistic persona to use in testing.
A is not correct because it is looking at a scenario rather than the user.
B is incorrect for the same reason.
C is incorrect because a user story is looking at a small bit of functionality and is concentrating on why the functionality is needed rather than the user.

Question No : 15
