In the draft sheet and in this question you must insert your exam code given to you by the person watching the exam. You exam is not valid without the exam code.
The exam is without consultation (no other windows or apps beside the one where the exam is being done). Otherwise, exam is annulled.
The exam has a time limit of 80 minutes. You can only leave after submitting your exam and only after 45 minutes. We take the best grade of the two exams.
There will be no further information about the exam questions (dúvidas acerca do enunciado) provided during the exam, besides the question text itself.
Answer the questions given the context in the question.
There are 24 actual questions in total in the exam, all graded with the same weight except the Map-Reduce problem that has a weight twice a normal (all others) question (1 mark -> 0.8 in 1-20 scale).
E.g. for a final grade of 8/20 ("valores") you need to sum up 10 marks, for a final grade of 15/20 ("valores") you need to sum up 18.75 marks. For a grade of 20/20 ("valores"), you need to sum up the 25 complete marks.

Good work. LV. Note: - Questions are presented in randomized order. Make sure you visit all of them. They cover different difficulty levels. - In all questions where a wrong choice may lead to penalty there is an option, e.g. "No response (no penalty if only option answered)". - When you must select only one option, an incorrect choice leads to a penalty (1/number-of-incorrect-or-not-fully-correct-choices), e.g., -33% in question with 4 options. - In questions where you can select multiple options, the correct and incorrect options are graded in a way that selecting all of them leads to zero score, there is never a penalty (in the special case of 1 right and 1 wrong selected, I will manually assign half the score of one correct option).
