Question
A supervisor reviews a case with a trainee for the CompTIA Network+ involving DNS in Troubleshooting. Which response best applies the concept? (Item 124)
Answer choices
- A. Skip verification because the previous case had the same answer.
- B. Document nothing because documentation could create follow-up questions.
- C. Rely on informal custom instead of the applicable rule, control, or standard.
- D. The best answer is to choose the networking concept, configuration, or troubleshooting step that best addresses the scenario for the DNS scenario.
Correct Answer
D. The best answer is to choose the networking concept, configuration, or troubleshooting step that best addresses the scenario for the DNS scenario.
Explanation
The correct answer is D because DNS is tested by asking candidates to choose the networking concept, configuration, or troubleshooting step that best addresses the scenario. The distractors reflect common exam mistakes: ignoring context, using informal shortcuts, skipping verification, or applying a rule from the wrong domain.
