ARP cache poisoning is the best answer because the affected endpoint’s traceroute shows an unexpected first hop, 10.20.10.10, with high latency before reaching the normal gateway path. The unaffected device connected to the same port reaches 10.20.10.1 as the first hop, which strongly suggests the issue is specific to the affected endpoint’s local ARP mapping rather than the switch port, router, or destination resource. ARP poisoning manipulates a host’s ARP cache so traffic is sent to the wrong MAC address, often enabling traffic interception or redirection. An on-path attack is possible as a result, but ARP cache poisoning is the specific mechanism. Resource exhaustion and DNS spoofing do not match the traceroute evidence.

End-of-life operating systems are those that are no longer supported by the vendor or manufacturer, meaning they do not receive any security updates or patches. This makes them vulnerable to exploits and attacks that take advantage of known or unknown flaws in the software. Patch availability is the security implication of using end-of-life operating systems, as it affects the ability to fix or prevent security issues. Other factors, such as product software compatibility, ease of recovery, or cost of replacement, are not directly related to security, but rather to functionality, availability, or budget. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 29 1

When a legacy device is no longer receiving updates or patches, it is considered to be at the end of life (EOL). This means the manufacturer has ceased support for the device, and it will no longer receive updates, security patches, or technical assistance. EOL devices pose security risks and are often decommissioned or replaced.

End of support may seem similar but typically refers to the cessation of technical support, whereas EOL means the device is fully retired.

End of business and End of testing do not apply in this context​​.

The best answer is B. Update user guidance to include suspicious incident reporting.

The phishing simulation results show that users were not fooled, which means awareness training is already helping them avoid credential theft. However, the employees deleted the email without reporting it. That means the organization missed an opportunity to:

investigate the message further

identify other recipients

block similar messages

improve incident response visibility

update defensive controls quickly

The most valuable next step is to train or guide users to report suspicious emails, not just ignore or delete them.

Why the other options are incorrect:

A. Implement a strict password reset policy for all senior managers after a security event.This does not address the gap identified by the exercise.

C. Conduct end-user training regarding spear-phishing attempts to raise awareness.The results already show awareness was effective enough to prevent users from falling for the message. The missing behavior is reporting.

D. Require remote workers to use a VPN when connecting to the organization ' s networks.This is unrelated to the phishing exercise outcome.

From a Security+ perspective, user awareness programs should teach employees to identify and report suspicious messages. Therefore, B is the best answer.
