Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 626

Which type of antenna is designed to provide a 360-degree radiation pattern?

Answer options

• A. Yagi
• B. patch
• C. directional
• D. omnidirectional

Correct answer: D

Explanation

The correct answer is D, omnidirectional, as it is specifically designed to radiate signals uniformly in all horizontal directions. In contrast, a Yagi antenna (A) focuses energy in a specific direction, a patch antenna (B) typically has a limited radiation pattern, and a directional antenna (C) also concentrates its radiation in a particular direction.
