You work for a company that is a pioneer in smart energy technology. One of their core products is their energy monitor in-home display device, used to display current and historic energy consumption data to many thousands of customers. It has been designed to integrate with their other smart-home products, including domestic lighting control systems via their HomeHub.
The company is to launch a new application for smartphones and tablets that will allow its customers to view their energy readings remotely and to view their daily budget usage based on seasonal historic data. The application must also support customers with disabilities.
The following requirement specification has been written and you are reviewing it:

Description:
* The customer's daily gas, electricity, and usage figures must be accurately displayed
* The customer's weekly gas, electricity, and usage figures must be accurately displayed
* The monthly gas, electricity, and usage figures must be accurately displayed
* The customer's annual gas, electricity, and usage figures must be accurately displayed
* The customer should be able to change between displaying gas only, electricity only, or both energy types
* The retrieval time for the customer's energy data must be less than 2 seconds from the opening of the application
* The screen design must be visually attractive and easy to operate for the customer You are using the following review checklist:
* Is each requirement testable?
* Does each requirement have acceptance criteria listed?
* Is a use case calling structure available (if applicable)?
* Are the requirements uniquely identified?
* Is the specification versioned?
* Is there traceability visible from each requirement to the business/marketing requirements?
* Is there traceability between the requirements and the use cases (if applicable)?
Based on this checklist, which items are NOT met and will fail review?
SELECT ONE OPTION

• A.1, 2, 4, 6
• B.1, 4, 5, 7

A software component for a game application calculates a player's trophy level based on two input parameter values: Points Earned and Level of Difficulty. A total score is calculated by the component as:
Total Score = Points Earned × Level of Difficulty
The trophy levels are:
* Blue- total score equal to or less than 40
* Silver- total score > 40
* Gold- total score > 70
* Diamond- total score > 80
* Platinum- total score > 90
The component then outputs the correct trophy level.
Applying theEquivalence Partition test design techniqueto this component, what percentage of output partitions have been exercised by the following suite of test cases?
* Player 1 - Points earned 25, level of difficulty 2
* Player 2 - Points earned 20, level of difficulty 3
* Player 3 - Points earned 30, level of difficulty 1
SELECT ONE OPTION:

• A.10%
• B.40%
• C.60%

To enhance both the effectiveness and efficiency of the test design phase, the purchase of a test design tool is being considered. Which one of these statements best characterizes a test design tool?

• A.A test design tool enables tests to be executed automatic ally.
• B.A test design tool validates models of the software.
• C.A test design tool generates test inputs from requirements
• D.A test design tool enables individual tests to be traced to requirements
