The correct answer is D. Upgrading the current mesh network to support the 802.11n specification. To address wireless network degradation due to high traffic, upgrading the existing mesh network to a newer, faster Wi-Fi standard like 802.11n is the most efficient way to increase capacity.
Question
A company installed WAPs and deployed new laptops and docking stations to all employees. The docking stations are connected via LAN cables. Users are now reporting degraded network service. The IT department has determined that the WAP mesh network is experiencing a higher than anticipated amount of traffic. Which of the following would be the most efficient way to ensure the wireless network can support the expected number of wireless users?
Options
- AReplacing non-mobile users' laptops with wired desktop systems
- BIncreasing the wireless network adapter metric
- CAdding wireless repeaters throughout the building
- DUpgrading the current mesh network to support the 802.11n specification

Why each option
To address wireless network degradation due to high traffic, upgrading the existing mesh network to a newer, faster Wi-Fi standard like 802.11n is the most efficient way to increase capacity.
Replacing non-mobile users' laptops with wired desktop systems would offload some traffic from the wireless network, but it's a costly and disruptive hardware change for an entire company, and not the most efficient way to improve the existing wireless network's capacity for its intended users.
Increasing the wireless network adapter metric changes the priority of the wireless connection relative to other network interfaces on a single client device and does not improve the overall capacity or performance of the wireless access points or the mesh network itself.
Adding wireless repeaters extends Wi-Fi range but does not increase the overall bandwidth or capacity of the network; repeaters often halve the available bandwidth, potentially worsening the high-traffic issue rather than resolving it.
Upgrading the mesh network to support a more modern Wi-Fi specification, such as 802.11n, significantly increases the maximum theoretical throughput and efficiency of the wireless network. This allows the WAPs to handle a higher volume of traffic and more concurrent users more effectively, directly addressing the degraded service due to high traffic.
