Cisco Updated 300-425 Exam Questions and Answers by isobelle

The sticky client issue occurs when a wireless client device clings to a suboptimal access point instead of roaming to a better one with a stronger signal. Enabling Optimize Roaming on the Cisco 9800 Series Wireless Controller can alleviate this issue. This feature prompts clients to roam by disassociating them when their signal strength drops below a threshold, encouraging them to seek a better connection.

 Before replacing old APs with IEEE 802.11ac-capable APs, it is crucial to check the software version of the wireless LAN controller. The controller’s firmware must support the newer standards and capabilities of 802.11ac APs. An outdated software version may not support the advanced features and performance enhancements offered by 802.11ac technology, leading to compatibility issues and suboptimal network performance.

Micro cells with reduced power levels are suitable for environments with a high concentration of wireless clients and multimedia applications, as they help manage interference and allow for better roaming capabilities. References: ENWLSD 300-425 Official Cert Guide.

In a medical treatment environment where both data and voice services are required, continuous coverage of -67 dBm from one access point is the minimum requirement. This ensures that there is sufficient signal strength for reliable voice communication, which is critical in medical settings. The -67 dBm threshold is commonly recommended for voice applications to ensure call quality and reliability.

So -67dBm covers both Data & Voice with a single AP
