Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 201

A network engineer is designing a new wireless network for a campus. The network must include these requirements:
• optimized performance
• avoid interference
• availability in high-density areas
• roaming

Which two approaches must be taken? (Choose two.)

Answer options

• A. 5 GHz frequency band with 80 MHz channels
• B. 2.4 GHz frequency band with 40 MHz channels
• C. 5 GHz frequency band with 20 MHz channels
• D. 2.4 GHz frequency band with 20 MHz channels
• E. 5 GHz frequency band with 40 MHz channels

Correct answer: C, D

Explanation

The correct answers are C and D because using a 5 GHz frequency band with 20 MHz channels (C) minimizes interference and enhances performance, while the 2.4 GHz frequency band with 20 MHz channels (D) is suitable for coverage in high-density areas. The other options either utilize wider channels that can increase interference or are suboptimal for high-density environments.
