CompTIA N10-009 Actual Questions

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.

BNC connectors are commonly used for coaxial cables, including those connecting to external antennas in Wi-Fi, radio, and surveillance systems.

Breakdown of Options:

A. BNC – Correct answer. Used for coaxial cables in wireless and antenna connections.

B. ST – Used for fiber optic cables, not antennas.

C. LC – A fiber optic connector, not for antennas.

D. MPO – Used for multi-fiber optic cables, not RF antennas.

The switch with the lowest STP priority becomes the root bridge.In the given table, core-sw01 has the lowest priority value of 24576. Therefore, it will be elected as the root bridge in the Spanning Tree Protocol topology.

Microwaves are known to interfere with the 2.4GHz frequency, which is the same frequency used by many wireless networks. This can cause signal degradation and intermittent connectivity issues, especially if the WAP is placed near such devices.
