Reading questions carefully

After her first full-length practice test, Noor sat with Lorna and went through every question she had answered wrongly. The result surprised both of them. Of the eighteen she missed, nine were on topics she genuinely did not know yet. The other nine she could explain once she reread them. She had missed the word NOT in one, chosen an answer that was true but not the best in two, overlooked that a question asked for the first step in one, and picked one answer where the question asked for two in another. She had also clicked the wrong option twice while rushing and guessed two at the end when time ran short. Half of her lost points came from reading, rushing and timing, not from knowledge. Lorna says this is the most common pattern she sees in new candidates, and the most fixable. This lesson is about reading exam questions the way they are written.

The anatomy of a multiple-choice question

Every Tech+ question has the same parts. The stem is the question itself, often with a short scenario first. The scenario gives the facts you are allowed to use: who the user is, what they need, what has already been tried. The question line, usually the last sentence of the stem, says exactly what is being asked: the best choice, the first step, the most likely cause, or the item that does not belong. The options are the possible answers. One is the key, the correct answer; the rest are distractors, written to look plausible to someone who has not read carefully or who has a partial understanding. Good distractors are usually true statements in general but wrong for this question.

Read the question line first, then the scenario

A simple habit makes a large difference: read the last sentence of the stem before the scenario. Knowing that the question asks for the most likely cause, or the first thing to do, tells you what to look for in the scenario. Then read the scenario carefully, noting the facts that matter: the device, the symptom, what changed, and any limits such as cost or speed. Finally, read every option before choosing. Candidates who pick the first option that looks right often miss a better one further down.

Lorna teaches a four-word routine: ask, read, predict, check. Ask: what is the question line asking for? Read: what facts does the scenario give? Predict: before looking at the options, what answer would you give? Check: which option matches your prediction, and does each other option fail for a clear reason? Predicting first protects against distractors, because you approach the options with your own answer rather than letting the options suggest one.

Keywords that change the answer

A handful of words in the question line change what counts as correct, and exam writers use them deliberately. BEST means several options may work, and you must choose the one that works best for the situation described. FIRST or NEXT means the order of actions matters; the right answer may not be the most important action overall, only the one that comes first. MOST LIKELY means choose the most probable cause given the facts, not every possible cause. NOT, EXCEPT and LEAST reverse the question, so you are looking for the one option that does not fit. Some questions ask you to choose two or three answers; the number is stated in the question line, and choosing a different number of options is marked wrong.

Using only the facts given

Scenario questions are built from the facts in the stem, and the right answer follows from those facts. A common error is to add facts from experience: "in my branch, the printer is always the problem, so it must be the printer." The exam's scenario may say nothing of the kind. Another error is to ignore facts that rule an option out. If the scenario says other computers on the same network are working, a network-wide outage is not the most likely cause, however familiar it might be. Underline, mentally or on the whiteboard, the facts that rule options in or out.

A related skill is noticing what has already been done. If the scenario says the user has restarted the computer, "restart the computer" cannot be the next step, even though it is often the right first step in real life. If the scenario says the cable has been replaced, a cable problem is unlikely. Exam writers include these details precisely to rule out the most obvious answers.

Eliminating distractors

When the answer is not obvious, eliminate options you can prove wrong. Each elimination raises the chance of choosing correctly. Some distractors are easy to remove: they are about a different topic, they contradict a fact in the scenario, or they are far too drastic for the problem, such as reinstalling an operating system to fix a printer setting. Options with absolute words such as always and never are often wrong, because few things in IT are always true, although this is a tendency, not a rule. If two options say almost the same thing, it is often the case that neither is correct, or that the difference between them is the point of the question.

Once you are down to two options, return to the question line. Which of the two answers exactly what is asked? If the question asks for the best protection against stolen passwords, both a longer password and multifactor authentication help, but MFA protects even when the password is known, so it is the better answer to that specific question. If you still cannot decide, choose the one that is simpler, safer or more standard practice, mark the question for review if the exam allows it, and move on.

Multiple-response questions

Some questions ask for more than one answer. CompTIA describes the Tech+ exam as multiple choice, and multiple-choice questions on CompTIA exams can ask candidates to choose more than one option; the question line says how many. Treat each option as a true-or-false statement about the scenario, then select exactly the number requested. If a question asks for two and three options seem right, the scenario usually contains a fact that rules one out. Read it again.

Look-alike terms and overthinking

Entry-level exams test many pairs of terms that look or sound alike, and a quick reader can swap them without noticing. Mbps and MBps, WPA and WPA3, authentication and authorization, primary key and foreign key, IaaS and PaaS, compiled and interpreted, virus and worm: each pair differs by one idea, and each pair makes a perfect distractor. Noor keeps a list of the pairs she has confused in practice and reads it aloud once a day. When one of those terms appears in a question, she slows down deliberately and says the distinguishing idea to herself before choosing.

The opposite problem is overthinking. Some candidates, especially those with real-world experience, imagine unusual situations in which the obvious answer would be wrong: "but what if the DNS server is also the DHCP server and the cable is half broken?" Exam questions are written to have one defensible best answer from the facts given, and that answer is usually the standard, textbook one. If an answer requires assumptions that the scenario does not state, it is probably not the intended answer. Lorna puts it bluntly: answer the question that was asked, about the situation that was described, using the method in the objectives.

A last reading trap is the answer that is too broad or too narrow. If a question asks which device connects wireless devices to the wired network, "a network device" is too broad to be the best answer and "a 6 GHz radio" is too narrow; "an access point" is exactly right. Prefer the option that matches the level of detail in the question line.

Building the habit

Careful reading is a habit, and habits come from practice. Noor adds a step to every practice session. For each question she answers, right or wrong, she writes down the keyword in the question line and the one fact in the scenario that decided the answer. Lorna expects the routine to feel automatic within two weeks; in cert club members who use it, reading errors usually fall sharply by the next practice test. She also points out that careful reading also speeds her up rather than slowing her down, because she spends less time going back and forth between options when she has predicted the answer first.
