CompTIA Updated N10-009 Exam Questions and Answers by sean

The correct answer is Active-active because a stock exchange broker requires extremely high availability, minimal downtime, and near-zero data loss. According to CompTIA Network+ (N10-009) objectives under high availability and disaster recovery concepts, an active-active configuration involves multiple systems or sites operating simultaneously and sharing the workload. If one system fails, the other continues processing traffic without service interruption.

This model provides the lowest Recovery Time Objective (RTO) and Recovery Point Objective (RPO), which is critical in financial trading environments where even seconds of downtime can result in major financial loss. Active-active architectures also support load balancing, redundancy, and continuous synchronization between systems.

A warm site (Option A) contains preconfigured hardware but may require data restoration and configuration before becoming fully operational, resulting in some downtime. A full mesh (Option C) is a network topology design and does not specifically address disaster recovery at the service level. In-band (Option D) refers to management traffic sharing the production network and is unrelated to DR strategy.

Therefore, an active-active approach is the most suitable solution for mission-critical financial operations.

An evil twin is a rogue Wi-Fi access point that mimics a legitimate network. Attackers use it to intercept and manipulate traffic, making it an on-path (formerly MITM) attack opportunity.

Breakdown of Options:

A. Phishing – Tries to steal credentials through fake emails/websites but does not intercept network traffic.

B. Dumpster diving – Involves physical security breaches, not network interception.

C. Evil twin – ✅ Correct answer. A rogue Wi-Fi AP impersonates a real network, allowing traffic interception.

D. Tailgating – Involves physical access security, not network interception.

A full-tunnel VPN routes all of a user ' s network traffic through the corporate network. This means that the organization can inspect all network traffic for security and compliance purposes, as all data is tunneled through the VPN, allowing for comprehensive monitoring and inspection.References: CompTIA Network+ study materials.

A golden configuration is a baseline configuration file that contains approved, standardized settings for network devices. The purpose is to ensure configuration consistency across the environment. This prevents misconfigurations, supports compliance with organizational or regulatory standards, and accelerates recovery if a device needs reconfiguration.

B. Reducing file size is not the goal of golden configs.

C. Golden configs can include security settings, but they are not inherently encrypted — they are simply a baseline template.

D. While configs can be backed up, golden configs are more about standardization, not device-specific backups.

By maintaining a golden configuration, administrators can quickly detect unauthorized changes (by comparing running configs against the golden file) and enforce consistency across devices. This improves network stability, reduces troubleshooting complexity, and enhances security posture.
