Arista Certified Engineer – Associate (ACE-A) — Question 39

Many Arista switches support reversible air flow. When the fans installed on such a switch have red handles, which of the following statements would be correct?

Answer options

• A. Cold air will be pulled in from the port side of the switch.
• B. Warm air will be pulled in from the starboard side of the switch.
• C. Hot air will be pulled in from the fan side of the switch.
• D. Hot air will be ejected from the fan side of the switch.

Correct answer: D

Explanation

The correct answer is D because in switches with reversible airflow and red-handled fans, hot air is expelled from the fan side to ensure efficient cooling. Options A, B, and C are incorrect as they misrepresent the direction of airflow related to temperature and switch orientation.
