Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 98

An engineer must perform a Layer 2 survey for a mining facility. Which type of antenna does the engineer use in the mine shaft?

Answer options

• A. omnidirectional
• B. patch
• C. internal
• D. dipole

Correct answer: B

Explanation

The patch antenna is ideal for Layer 2 surveys in confined spaces like mine shafts due to its directional capabilities and ability to focus signals. Omnidirectional antennas, while useful in open areas, do not provide the same level of signal precision needed in such environments. Internal antennas may lack the range and performance required, and dipole antennas are not as effective in the confined layout of a mine shaft.
