The most likely cause of buffering issues when moving outdoors is signal degradation. Wireless signals weaken as they travel through obstacles such as walls, glass, and air, leading to weaker connections and reduced data rates.

Breakdown of Options:

A. Network congestion – While congestion can slow down network speeds, it affects all users, not just those moving outdoors.

B. Wireless interference – Interference is possible but is more likely caused by other wireless signals rather than outdoor movement.

C. Signal degradation – Correct answer. Wireless signals weaken with distance and obstacles such as walls, reducing performance.

D. Client disassociation – Disassociation occurs when clients lose connection to the AP, but the question states that users experience buffering, indicating they are still connected but with a weak signal.

When high-bandwidth services like videoconferencing are introduced, two primary factors may degrade performance:

Incorrect QoS Settings (E):QoS (Quality of Service) is used to prioritize traffic. If not configured correctly, critical services like video may not get the necessary bandwidth and prioritization.

Network Congestion (F):Video services consume large amounts of data. If the network doesn’t have sufficient bandwidth or is not segmented properly, congestion will slow down all services.

DNS misconfiguration (A) would affect name resolution, not bandwidth.

Malware (C) could degrade performance, but is not tied to the described scenario.

Outdated software (D) may affect performance in some cases, but not directly linked to network congestion in this case.

Inadequate network security (B) isn't likely to cause general slowness related to video traffic.

✅ So, the most likely culprits are E. Incorrect QoS settings and F. Network congestion.
