First, we need to know what will satisfy the question. Here there are two ports on the device one is for power. Check the answers and the only one relative to power is 12v DC jack. Now you have one of your two answers since none of the others reference power at all. You’ll see other voltages in the field but remember that the world you are in right here only has one listing a power rating and so it is your “BEST” choice. Now to Security, we want to know which choice has no electrical properties and provides security. On the list you can see a NIC, HDMI, and a USB port. All of those use some form of electrical energy, so they are out. We’ve used the 12v answer and we are left with the Cable lock which is correct because it is a security component.

During the test, monitor your timing. The A+ Exam allows for approximately one question per minute. You will find that easy questions (i.e. any question for which you know the answer immediately) may take as little as five seconds to complete. However, as the questions become more complex, they may take you a lot longer. This is where you need to determine when something is taking too long and mark the question and jump to the next question. We recommend that, if after a minute you are still completely in the dark, you use the “Mark for later” feature and come back to the question after having had the opportunity to answer all the other questions you are comfortable with. This way you are less likely to run out of time. Also, your brain may have processed the question “in the background” while you were answering the rest of the questions. When that happens you may find that a question that seemed impossible to answer on the first brush is now suddenly “easy”.

Take the test in stages where you can look at (and answer) every question during your first look. Mark for later anything any question that will cost too much time and slow you down. When you do Mark for later an MCQ do take a quick guess as with four choices a completely random selection will yield a 25% chance vs. zero if you don’t take a guess. When you come back to all your Marked for later questions, the correct response may jump right out at you, if so great! Answer it and move on. You want to work yourself down the exam questions to where you only “leave on the table” the questions you have no idea about (still take a guess on those though) but where you gave yourself the opportunity to answer every question you know the answer to.
