The following state transition diagram describes the functionality involved in a system using fingerprint and password authentication to log onto a system.
How many distinct states of the system are visible in the above diagram?
The state transition diagram provided shows three distinct states:
Waiting for fingerprint
Waiting for PIN
Valid PIN/ask menu selection
Each state represents a different stage in the system's operation, with transitions based on user actions and system responses.
Consider an estimation session in which a six-member Agile team (Memb1..... Memb6) uses the planning poker technique to estimate a user story (in story points). The team members will use a set of cards with the following values: 1,2, 3,5, 8,13,21. Below is the outcome of the first round of estimation for this session:
Which of the following answers BEST describes how the estimation session should proceed?
In Agile teams using the planning poker technique for estimating user stories, it is common practice to have further discussions and rounds of estimation if there is a significant discrepancy in the initial estimates. This helps in reaching a consensus and ensures that all team members understand the complexity and requirements of the user story. According to the ISTQB CTFL syllabus, planning poker involves discussions to clarify differences in estimates, especially when there is a wide range of values selected. By having Memb6 and Memb4, who provided the most pessimistic and optimistic estimates, explain their reasoning, it fosters a deeper understanding and encourages the team to converge towards a more accurate and agreed-upon estimate.
You are testing the latest version of an air-traffic control system prior to production deployment using exploratory testing. After following an unusual sequence of input steps, the system crashes. After the crash, you document a defect report with the following information:
* Title: System crashes unexpectedly during input.
* Brief summary: System crashes when an unusual sequence of inputs is used.
* Version: V1.001
* Test: Exploratory testing prior to production deployment
* Priority: Urgent
* Risk: High
* Reference: Screenshot of crashed application
What critical Information Is missing from this report?
The critical information missing from the defect report is a detailed description of the defect to enable reproduction. A clear and concise description of the steps taken to reproduce the defect is essential for developers to understand the context and to be able to replicate the issue in their environment. Without this information, it can be challenging to diagnose and fix the defect. The ISTQB CTFL syllabus emphasizes the importance of providing all necessary details in a defect report to facilitate effective communication and resolution.
During iteration planning, a scrum team uses an estimation technique called planning poker to estimate the effort required to deliver a critical user story. In advance of the estimation session, the team agreed on some ground rules to limit the number of poker rounds and save time.
The team agreed on the following:
1. They will use the following progression for estimation: Extra-small, Small, Medium, Large, Extra-large, and Extra-extra-large.
2. If estimation values differ significantly, the highest score will be used for estimation purposes.
The result of the first round of planning poker:
Team Member Estimation
Business Large
Development Extra-extra-large
Testing Extra-extra-large
Which of the following options best represent the team's next actions?
In a planning poker session, if there is a significant difference in the estimations, it indicates that there may be misunderstandings or different perspectives on the complexity of the user story. According to the agile principles, the team should discuss these differences to reach a common understanding. The goal is to ensure that all team members have a shared understanding of the user story's scope and complexity before finalizing the estimate.
Select the roles required in a formal review:
In a formal review, the roles involved typically include the author, management, facilitator (also known as moderator), review leader, reviewers, and scribe. Each role has specific responsibilities to ensure the effectiveness and efficiency of the review process:
The author creates and refines the work product being reviewed.
Management allocates resources and supports the review process.
The facilitator manages the review meeting, ensuring it proceeds smoothly.
The review leader plans the review and ensures it meets its objectives.
Reviewers examine the work product to identify defects.
The scribe records issues raised during the review meeting.
