CompTIA Updated N10-009 Exam Questions and Answers by tiago

The most likely answer is D. Switch bandwidth is creating a bottleneck. Even though the company upgraded the wireless environment with newer access points and new tablets, wireless performance still depends on the capacity of the wired network that the APs connect back to. If multiple APs are sending traffic through a shared switch uplink or limited switch bandwidth, that wired segment can become the choke point, preventing users from seeing the benefit of the newer wireless equipment.

This kind of issue shows up often when organizations focus on upgrading the wireless edge but do not account for the aggregate traffic load feeding into the switching infrastructure. Faster wireless standards can increase the amount of traffic that reaches the switch, but if the switching path cannot handle that volume efficiently, end-user throughput will still feel unchanged.

The other options are less convincing. One AP having no connected devices does not explain why speeds on active clients are not improved. VLAN assignment problems would more likely cause access or segmentation issues rather than a general performance ceiling. Device congestion can hurt performance, but the information given points more strongly to the wired backhaul as the limiting factor.

In this scenario, the wireless upgrade is being held back by the switching side of the network, making switch bandwidth bottleneck the best answer.

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.

Using Pre-Shared Key (PSK) authentication means that all users share the same Wi-Fi password, making it difficult to identify individual users when security incidents occur.

Migrating to WPA2-Enterprise (or WPA3-Enterprise) replaces PSK authentication with individual user credentials using 802.1X authentication and a RADIUS server. This allows the organization to:

Track and log specific user activity

Enforce per-user authentication policies

Improve network security

Breakdown of Options:

A. Restrict users to the 5GHz frequency – Improves performance but does not enhance user tracking or security.

B. Upgrade to a mesh network – A mesh network improves coverage, not security tracking.

C. Migrate from PSK to Enterprise – ✅ Correct answer. WPA2-Enterprise or WPA3-Enterprise uses individual user authentication, allowing per-user tracking.

D. Implement WPA2 encryption – WPA2 is already widely used; it does not resolve the tracking issue.

The correct answer is D. Hot site. In CompTIA Network+ N10-009, disaster recovery and business continuity concepts include understanding recovery site types and how quickly they can restore operations after a major outage or catastrophe. A hot site provides the fastest recovery because it is a fully operational alternate location with the necessary network infrastructure, hardware, systems, connectivity, and often replicated data already available. Since the environment is prepared and ready to assume production workloads, organizations can fail over to a hot site with minimal downtime.

A warm site is partially prepared and may have network connectivity and some hardware in place, but it usually requires additional configuration, data restoration, or system activation before services can fully resume. A cold site provides only basic facilities, such as space, power, and cooling, but lacks most operational equipment and therefore has the longest recovery time. Asynchronous replication is a data replication method where changes are copied after they occur, but it is not itself a complete recovery location and may involve some data loss depending on timing.

Because the question asks which option allows the fastest recovery during a catastrophe, the best choice is a hot site.
