An engineer must segment traffic into separate WLANs. Which three factors should be used to determine traffic segmentation? (Choose three.)

QoS policy is a primary driver because different traffic classes (voice, video, data) require distinct priority treatment, which necessitates separate WLANs to enforce policies cleanly.

Subnet requirements are an output of the segmentation decision, not a determining input factor when designing WLAN separation.

Application requirements determine which WLAN a device belongs to because different apps have different bandwidth, latency, and reliability needs that influence segmentation design.

Security capabilities drive segmentation by isolating traffic with different trust levels, encryption standards, or authentication methods into separate WLANs to enforce least-privilege access.

Access control policies for voice are too narrowly scoped to a single application type and are already captured under the broader application requirements and QoS policy factors.

Enterprise resource planning is a business software category and has no direct bearing on the technical criteria used to segment wireless traffic.
