Question # 29

Consider an estimation session where a six-member Agile team (Memb1, ... , Memb6) is performing a planning poker session to estimate a user story (in story points). Team

members are using a set of cards with the following values: 1, 2, 3, 5, 8, 13, 21. Below is the outcome produced by the first round of estimation for this session:

Which of the following answers best describes how the estimation session should proceed?

A.

The final estimate of the user story in story points is determined as the arithmetic mean of all the estimates made by the team members during this first round, without the need to perform further rounds of estimation

B.

The final estimation of the user story in story points is determined as the most frequent estimate value among those selected by the team members (in this case 3 story points chosen by Memb1, Memb2, Memb3, Memb5) during this first round, without the need to perform further rounds of estimation

C.

The final estimate of the user story in story points is determined as the arithmetic mean of the most optimistic estimate (chosen by Memb6) and the most pessimistic estimate (chosen by Memb4) during this first round, without the need to perform further rounds of estimation

D.

Memb4 and Memb6, which have produced the most pessimistic and the most optimistic estimates respectively, should explain the reasons of their choices to stimulate a discussion between all team members before to proceed to another round of estimation

Question # 30

Scenario 1 “Happy Tomatoes” (used for questions 20-22):

An intelligent application for agricultural use incorporates temperature sensors located at different points of an enclosure. The sensors measure and record the temperature at regular intervals and extract the statistical values for these measurements. These values include the average daily temperature.

A new variety of tomatoes is currently being grown and the“World Organization for Happy Tomatoes”has established temperature ranges related to vegetative development.

When the system establishes that the average temperature is within a specific range, it emits a value that will be used to monitor and control the crop.

Using theequivalence partitioningtechnique, identify the set of input values that provides the HIGHEST coverage.

A.

{7,10,21,40}

B.

{8,10,25,40}

C.

{7,10,25,29}

D.

{7,10,25,40}

Question # 31

Consider the following defect report for an Exam Booking System

Defect ID: ST1041 | Title: Unable to cancel an exam booking | Severity: Very High | Priority: Very High | Environment: Windows 10, Firefox

Description: When attempting to cancel an exam booking using the cancel exam feature, the system does not cancel the exam even though it shows a message that the exam has been cancelled.

Which ONE of the following indicates the information that should be added to the description for reproducing the defect easily?

A.

Repeating the test case with different browsers and logging a separate defect for each one of them

B.

Providing exact steps that lead to this defect. It is not clear from the description if this is a problem for any scheduled exam or for a specific user.

C.

Providing better severity and priority. It is not clear why this is a high severity problem as the exams can be booked without any problem.

D.

The defect Id used is alphanumeric in nature. It should be a number only.

Question # 32

Which of the following is an advantage of the whole team approach?

A.

It helps avoid the risk of tasks associated with a user story not moving through the Agile task board at an acceptable rate during an iteration

B.

It helps team members understand the current status of an iteration by visualizing the amount of work left to do compared to the time allotted for the iteration

C.

It helps the whole team be more effective in test case design by requiring all team members to master all types of test techniques

D.

It helps team members develop better relationships with each other and make their collaboration more effective for the benefit of the project
