CompTIA Updated N10-008 Exam Questions and Answers by zayden

802.11n is a wireless standard that supports data rates up to 600 Mbps and operates in both 2.4 GHz and 5 GHz frequency bands. 802.11n is backward compatible with 802.11g, which operates only in 2.4 GHz band. 802.11n is the least expensive solution that can upgrade the wireless infrastructure for the company, as it does not require replacing all the access points or wireless devices

Given that the longer cables within the infrastructure are working correctly but the newly installed patch cables are causing connectivity issues, the most likely cause is an incorrect pinout on the patch cables. If these cables were not properly crimped according to the T568A or T568B wiring standards, they could easily cause a failure in connectivity due to incorrect alignment of the transmitting and receiving pins. This is a common issue with DIY or newly crimped cables where mistakes in the wire arrangement can render the cables non-functional. The other listed issues, such as mixed cable types, plenum rating, or cable distance exceedance, would not typically result in a total loss of connectivity as described​​.

 No more patches or bug fixes are available indefinitely. This indicates that a computer has reached end-of-support, which means that the manufacturer or vendor of the hardware or software no longer provides technical assistance, updates, or security fixes for the product12. This can expose the computer to potential security risks and compatibility issues with newer technologies

A vulnerability is a security flaw in an application or network that can be exploited by an attacker, allowing them to gain access to sensitive data or take control of the system. Vulnerabilities can range from weak authentication methods to unpatched software, allowing attackers to gain access to the system or data they would not otherwise be able to access. Exploits are programs or techniques used to take advantage of vulnerabilities, while threats are potential dangers, and risks are the likelihood of a threat becoming a reality.
