Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 522

When voice services are deployed over a wireless environment, which service must be disabled to ensure the quality of calls?

Answer options

• A. priority queuing
• B. dynamic transmit power control
• C. aggressive load balancing
• D. Fastlane

Correct answer: C

Explanation

Disabling aggressive load balancing is crucial because it can cause call interruptions and quality degradation due to frequent handoffs between access points. The other options, such as priority queuing and dynamic transmit power control, actually help enhance call quality rather than hinder it. Fastlane is a feature designed to prioritize voice traffic and is not detrimental to call quality.
