Free Access CompTIA N10-009 New Release

Band steering is a feature in wireless networks that encourages dual-band capable devices to connect to the 5GHz band instead of the 2.4GHz band.

Why Band Steering?

The 5GHz band supports higher speeds and less interference compared to 2.4GHz.

If a device supports both bands, the access point (AP) can "steer" it to connect to 5GHz instead of 2.4GHz.

This helps ensure users always connect to the fastest available network.

Incorrect Options:

B. Disabling the 5GHz SSID: Would force devices onto 2.4GHz, which is slower and more congested.

C. Adding a Captive Portal: Used for guest authentication, not for speed optimization.

D. Configuring MAC Filtering: Used for security, not for optimizing network speed.

If the company’s SSID is not visible in some areas while other networks are still visible, the most likely cause is insufficient wireless coverage. The wireless signal does not reach those areas, meaning additional access points or signal boosters may be required.

Breakdown of Options:

A. Interference or channel overlap – Would cause slow or unstable connections, but the SSID should still be visible.

B. Insufficient wireless coverage – ✅ Correct answer. If the SSID is not appearing, the signal is too weak in that area.

C. Roaming misconfiguration – Would cause devices to stay on weaker APs instead of switching, but the SSID should still be visible.

D. Client disassociation issues – This would disconnect users, but they should still see the network.

An on-path attack (formerly known as a man-in-the-middle (MITM) attack) involves intercepting and potentially altering communications between two parties without their knowledge. This can be done via techniques like ARP poisoning, rogue access points, or SSL stripping.

Breakdown of Options:

A. Self-signed certificate – These are untrusted SSL certificates but do not intercept traffic.

B. VLAN hopping – VLAN hopping exploits VLAN misconfigurations but does not necessarily intercept communications.

C. On-path attack – Correct answer. This intercepts and modifies traffic between two endpoints.

D. Phishing – Phishing tricks users into revealing credentials rather than intercepting network traffic.
