NEW QUESTION # 44
An engineering company's Chief Financial Officer recently fall victim to a phishing scam by responding to an urgent email. The mail appeared to be from a trusted business partner, and it requested sensitive tax information. The incident led to significant financial and reputational damage. To prevent similar occurrences 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
Explanation:
A targeted education campaign directly addresses phishing by training employees, especially high-value targets like executives, to recognize social engineering attempts. While technical controls help, phishing primarily exploits human behavior, so awareness and training are the most effective preventive measures.
NEW QUESTION # 45
A developer is building new API functions for a cloud-based application. Before writing the code, the developer wants to ensure that destructive actions, including deleting and updating data, are properly protected by access control identifying sensitive fields such as those that contain passwords or personally identifiable information. Which approach must be used to score the risks proactively?
Answer: D
Explanation:
Open API Specification Analysis evaluates API definitions before code is written, identifying risky endpoints (such as delete or update functions) and sensitive fields (like PII or passwords). This allows developers to proactively score risks and apply proper access controls early in the design phase.
NEW QUESTION # 46
An administrator at a large university wants to ensure that the new employees have the right level of access when they are onboarded. The administrator asked the team to configure the cloud environment and ensure that new employees have the appropriate access based on their roles and responsibilities. Which technique must be recommended to ensure the right level of access?
Answer: D
Explanation:
Identity Access Management (IAM) enforces role-based access control, ensuring that new employees are automatically given the correct permissions aligned with their roles and responsibilities. This approach secures the cloud environment by preventing excessive or inappropriate access.
NEW QUESTION # 47
The network security team of a private university is conducting a comprehensive audit to evaluate the security posture across the network infrastructure. During the review, the security team found that a trusted vendor disclosed serious vulnerabilities identified in a product that plays a crucial role in the university's CI/CD pipeline. The security team must act promptly to mitigate the potential risks posed by these vulnerabilities.
Which action must the security team take first in response to the disclosure?
Answer: A
Explanation:
According to theCisco Security Incident Responselifecycle and theNIST SP 800-61standards referenced in the SDSI objectives, the very first step in responding to a third-party vulnerability disclosure isIdentification and Validation. Before a team can patch, notify stakeholders, or monitor for exploits, they must perform an asset inventory check to confirm whether the specific vulnerable version of the product is actually running within their environment.
In a complex CI/CD pipeline, multiple tools and versions coexist. Jumping straight to patching (Option D) without validation can lead to unnecessary downtime or "breaking" integrated workflows if the vulnerability doesn't actually apply to the version in use. Similarly, using an IDS (Option A) is a detection/monitoring step that follows the confirmation of risk. Notifying customers (Option B) is a later phase in the incident response process, usually reserved for confirmed breaches or significant service impacts. By confirming the presence and version of the software first, the security team can accurately assess theblast radiusand prioritize remediation efforts based on the actual risk to the university's specific infrastructure. This systematic approach ensures that resources are allocated efficiently and that the security posture is managed based on verified data rather than assumptions.

NEW QUESTION # 48
An IT company experienced the spread of malicious content between user endpoints, which impacted business critical resources. The company wants to implement a solution to control communication between individual endpoints on the network. Which approach achieves the goal?
Answer: D
Explanation:
The spread of malicious content between endpoints is a classic case oflateral movement. To control and restrict communication between individual endpoints-regardless of their physical location or IP address- Cisco TrustSecis the recommended architectural approach. TrustSec moves away from traditional, IP-based Access Control Lists (ACLs), which are difficult to manage and scale, and instead usesScalable Group Tags (SGTs).
With TrustSec, every endpoint is assigned an SGT based on its role or security context (e.g., "Employee,"
"Contractor," or "HR"). Security policies are then defined in a centralized matrix (the egress policy matrix) that dictates which SGTs can talk to one another. For example, a policy can be set so that endpoints in the
"Developer" group cannot communicate directly with endpoints in the "Sales" group, effectively preventing malware from hopping between machines. WhileRADIUS(Option A) is the protocol used for authentication, it does not perform the segmentation itself.Posture(Option C) checks the health of the device, andProfiling (Option D) identifies what the device is, but neither provides the policy-based traffic control of TrustSec. By implementing TrustSec, the company achievesmicro-segmentation, significantly reducing the internal attack surface and containing potential breaches within a single group, which is a core goal of modern secure infrastructure design.
