200-301 Question #984: Real Exam Question with Answer & Explanation

Question

A project objective is to minimize the association time to the different access points as mobile devices move around the office. The ideal solution must cover numerous devices and device types, including laptops, mobile phones, tablets and wireless printers. What must be configured?

Options

• A802.11v BSS Max Idle Service
• B802.11v Disassociation Imminent
• C802.11ax BSS configure
• D802.11k neighbor List Dual Band

Explanation

This question asks for the 802.11 standard feature designed to minimize association time during client roaming.

Common mistakes.

• A. 802.11v BSS Max Idle Service is related to clients being able to remain associated with an AP for longer periods while inactive, not directly aimed at minimizing active association time during roaming.
• C. 802.11ax (Wi-Fi 6) is the newest generation of Wi-Fi technology focused on efficiency and capacity, but it doesn't specifically define a mechanism like 'Disassociation Imminent' for faster roaming association time; roaming improvements are often from 802.11k/v/r.
• D. 802.11k Neighbor List provides information about neighboring APs to clients, helping them make better roaming decisions, but it doesn't directly trigger or minimize the association time itself; it aids the discovery phase.

Concept tested. 802.11v roaming assistance features
