The client is experiencing issues with Jitter, as depicted in Option B. Jitter refers to the variation in time between packets arriving, caused by network congestion, timing drift, or route changes. In voice communications, jitter can manifest as the occasional dropping out of voice on phone calls because the variable delay can affect the steady stream of voice packets needed for a clear conversation. Even when there is no packet loss, high levels of jitter can significantly impact the quality of Voice over IP (VoIP) calls. Quality of Service (QoS) settings are essential in managing jitter, as they can prioritize voice traffic over other types of data, ensuring that voice packets are delivered consistently and in the correct order to minimize delays and prevent call quality degradation. Aruba Campus Access solutions would typically include QoS features to manage and mitigate jitter on the network.

When upgrading a WLAN infrastructure, it's important to ensure that the existing wired network can support the new wireless access points (APs) in terms of connectivity and power (if using Power over Ethernet, PoE). For 'No-Stair Inc.,' which is planning a WLAN refresh without specific changes to the Wi-Fi or security requirements but potentially with new AP models and configurations, verifying the capacity of the wired network is crucial. The question about whether the existing wired network has enough drops (ethernet connections) for the upgraded Wi-Fi network addresses this concern. It's essential to ensure that there are sufficient ethernet ports available in the right locations to connect the new APs, and that these ports can provide the necessary power and data rates required by modern APs. This information will help in planning the deployment of the new APs, avoiding potential bottlenecks and ensuring that the upgraded WLAN can deliver the desired performance and coverage

The primary differences between OM4 and OM5 cabling include their support for transmission distances and the type of multimode fiber. OM4 fiber supports distances up to 100 meters when using 100 Gbps transceivers (Option A), which is suitable for most data center and enterprise networking applications. OM5, also known as Wide Band Multimode Fiber (WBMMF) (Option C), extends this capability by supporting higher wavelengths in the 850 to 950 nm range, allowing for more efficient multiplexing and potentially longer distances or higher bandwidths under certain conditions. This makes OM5 a more versatile and future-proof option for organizations looking to deploy advanced technologies like shortwave division multiplexing.
