Aconflict of interest (B)arises when personal relationships or interests could potentially influence professional decisions. In this case, the CFO's friendship with the vendor could improperly affect the procurement decision- making process.
This scenario falls underDomain 5.3: Explain the importance of frameworks, policies, procedures, and controls-specifically under"Personnel policies (e.g., conflict of interest, mandatory vacations, job rotation)." Reference: CompTIA Security+ SY0-701 Objectives, Domain 5.3 - "Personnel policies: Conflict of interest."

Detailed Explanation:Smishing is a type of phishing attack that uses SMS text messages to deceive recipients into taking actions such as revealing sensitive information. The urgency in the text indicates this vector.

Google hacking is the correct passive reconnaissance activity. Passive reconnaissance collects information without directly interacting with the target's systems in a way that is likely to trigger alerts. Google hacking uses search engines and advanced search operators to discover publicly indexed information, such as exposed documents, login pages, metadata, directories, or sensitive files. DNS zone transfers require querying the target's DNS infrastructure and are considered active reconnaissance. Vulnerability scanning sends probes to target systems and is also active. Social engineering interacts with people and attempts to manipulate them, so it is not passive technical reconnaissance. In a penetration test, Google hacking is a classic OSINT method because it gathers public information without touching the target network directly.

Because the organization plans to deploy high-powered wireless access points, the next critical step is to create a heat map of the building perimeter. CompTIA Security+ SY0-701 highlights wireless heat maps as an essential design tool for identifying signal bleed, coverage overlap, dead zones, and areas where wireless signals extend beyond intended boundaries.
Stronger access points increase the risk of signal leakage outside the building, which could allow unauthorized users to attempt connections from parking lots or nearby buildings. A heat map enables the security team to visualize RF propagation and adjust power levels, antenna placement, and access point locations to minimize external exposure while maintaining internal coverage.
Deploying IPSec tunnels (B) is unnecessary for standard WLAN architectures. Enabling WPA2-PSK (C) weakens security compared to WPA3. Disabling SSH administration (D) is a hardening step but does not address wireless coverage risks.
Therefore, the correct next step in secure Wi-Fi design is A: Create a heat map of the building perimeter.
