Question 100
The team at an industrial warehouse has corrected this condition: An engineer attributes a wireless throughput increase entirely to moving from 802.11ac to 802.11ax without checking channel utilization. Which preventive practice BEST addresses the identified mechanism?
Explanation
Correct Answer
Require like-for-like multi-client throughput measurements for wireless technology claims. This repeatable safeguard addresses the mechanism—pHY-generation improvements do not guarantee higher application goodput on an uncongested or bottlenecked path—and reduces the chance that the specific fault recurs.
Incorrect Answers
Evaluate both uplink and downlink margins when setting AP transmit power. This protects against another issue—a stadium deploys APs at maximum transmit power and then mobile clients struggle to send frames reliably back—but is not the most direct prevention for an engineer attributes a wireless throughput increase entirely to moving from 802.11ac to 802.11ax without checking channel utilization.
Inventory supported client PHY capabilities before wireless service and band migration. This protects against another issue—a warehouse survey labels a legacy 802.11g-only scanner as an 802.11ax client and expects 6 GHz connectivity—but is not the most direct prevention for an engineer attributes a wireless throughput increase entirely to moving from 802.11ac to 802.11ax without checking channel utilization.
Capture AP and client PHY capability matrices before promising multi-link or advanced throughput features. This protects against another issue—a network architect assumes enabling 802.11ax on an AP automatically provides 802.11be multi-link operation to every client—but is not the most direct prevention for an engineer attributes a wireless throughput increase entirely to moving from 802.11ac to 802.11ax without checking channel utilization.
