Question 1 · Secure Infrastructure Open

An IT company experienced malicious content spreading between user endpoints, affecting business-critical resources. The company wants to implement a solution that controls communication between individual endpoints on the network. Which approach accomplishes this goal?

Answer: B Cisco TrustSec provides role-based, topology-independent segmentation by assigning users and devices to security groups and enforcing access-control policy between those groups. This limits lateral communication among endpoints and helps contain malicious-content spread. **Learn more:** [Cisco TrustSec Overview](https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9300/software/release/17-18/configuration_guide/cts/b_1718_cts_9300_cg/cisco_trustsec_overview.html)

Question 2 · Artificial Intelligence, Automation, and DevSecOps Open

A logistics company intends to deploy an application in the cloud by using cloud-native techniques. The company must make the development, testing, and production environments as identical as possible while minimizing the risk that development and testing environments affect production. Which solution must be used to accomplish this task?

Answer: C Separate cloud accounts provide hard isolation boundaries between development, testing, and production workloads, reducing the risk that non-production changes, access, or failures impact production while allowing equivalent environment configurations. **Learn more:** [AWS account management and separation — Security Pillar](https://docs.aws.amazon.com/wellarchitected/latest/security-pillar/aws-account-management-and-separation.html)

Question 3 · Risk, Events, and Requirements Open

An engineering company’s Chief Financial Officer recently fell victim to a phishing scam after responding to an urgent email. The email appeared to come from a trusted business partner and requested sensitive tax information. The incident caused significant financial and reputational damage. To prevent similar incidents in the future, the security team must implement an effective mitigation strategy. Which mitigation strategy must the security team implement to prevent similar occurrences in the future?

Answer: B A targeted education campaign can train personnel—especially high-risk executives—to recognize impersonation, urgency, and sensitive-information requests in phishing messages, and to verify or report them before responding. This directly addresses the social-engineering weakness exploited in the incident.
