You are developing the code that controls an industrial Espresso machine which will be operated by waiting staff in restaurants.
The machine is rather complicated and has lots of switches and buttons, so in the next iteration instructions will be provided to the operator on a small LCD screen.
A User Story for the Operator-Instructions module is as follows:
"As an operator of the Espresso machine, I would like to know how to steam milk, so I can add steamed milk to the coffee." The following is a list of risks identified for this story, with assigned probability and impact.
Which of these is most correct in the context of the given User Story?
SELECT ONE OPTION

• A. Operators will not read the instructions and will try various switches and buttons until something works. Probability: Low. Impact: Low
• B. The instructions may be incorrect or appear in the wrong order. Probability: Low. Impact: High
• C. A small child may try to steam milk. Probability: High. Impact: Low
• D. An untrained customer will attempt to use the coffee machine. Probability: High. Impact: High

Which of the following statements about the Planning poker test estimate technique are CORRECT?
i) Planning poker is a consensus based technique using a deck of cards.
ii) A low test estimate usually means the story should be broken down into multiple smaller stories.
iii) A high test estimate usually means the story should be broken down into multiple smaller stories.
iv) One poker round is played and then consensus has to be reached.
v) The risk level of each backlog item should be decided before the poker session.
SELECT ONE OPTION

• A. ii. iv
• B. ii, iii, iv
• C. i, ii, iii
• D. i, iii. v

In a sprint planning, the product owner presents a user story written on a card. The team starts having a discussion with the product owner to get an understanding on how the software should work.
The user story written on the card is:
"As a customer, I want to subscribe to the mailing list so that I can receive the latest deal in an email." By applying the 3C concept, which ONE of the following statements is CORRECT?
SELECT ONE OPTION

• A. The card should contain requirements not the user story.
• B. Product owner has written a user story and confirmation is not needed.
• C. Conversation should include the acceptance criteria discussion.
• D. The conversation is not required and the team should start developing.

Consider an online application that allows registered users to pay the annual car tax based on the vehicle's engine power in kW. Given the following user story:
"As a customer I need the online application to calculate the annual car tax amount that I need to pay for my car":
- If the power of the vehicle is less than 20 kW, then the annual car tax is free
- If the power of the vehicle is more or equal than 20 kW but less or equal than 150 kW, then the annual car tax is 250 Euros
- If the power of the vehicle is more than 150 kW, then the annual car tax is 750 Euros" What is the MOST suitable use of a black-box test design technique for this user story?
SELECT ONE OPTION

• A. Use case testing.
  Test the following use case (Actor=registered user):
  Pre-condition=registered user logged in
  Scenario=registered user inserts the power of the vehicle, making payment and logs out Post-condition=car tax paid and registered user logged out
• B. State transition testing. Test the transitions between the following states: logging In. inserting the power of the vehicle, making payment, logging out
• C. Equivalence partitioning. Test the annual car tax value for the following partitions: [power of the vehicle<20 kW; 20 kW ?power of the vehicle?! 50 kW; power of the vehicle>150 kW]
• D. Decision table testing. Test the following conditions:
  Condltions=reglstered user logged In; inserted power of the vehlcle=20kW; Action=Car tax paid
