Cisco Designing Cisco Security Infrastructure Sample Questions (Q44-Q49):

NEW QUESTION # 44
Which tool must be used to prioritize incidents by a SOC?

Answer: B

Explanation:
A SIEM (Security Information and Event Management) tool collects and correlates security logs from across the enterprise, then applies analytics to prioritize incidents for SOC analysts. This enables efficient detection and response to the most critical threats.


NEW QUESTION # 45
When designing security for applications distributed across multiple cloud providers, what is a key consideration?

Answer: C

Explanation:
Consistent identity and access management policies across cloud providers ensure uniform security controls and simplify governance in multi-cloud environments.


NEW QUESTION # 46
Which generative AI impact is addressed by a human-in-the-loop design policy?

Answer: A

Explanation:
In the realm of Artificial Intelligence security,AI hallucinationsoccur when a generative model perceives patterns that are non-existent or logically incorrect, leading to the creation of content that is nonsensical, factually wrong, or potentially dangerous. To mitigate the risks associated with these inaccuracies, ahuman- in-the-loop (HITL)design policy is essential. This policy ensures that human judgment and contextual understanding are integrated into the AI's decision-making or output validation process.
According to theCisco SDSI v1.0objectives, while AI is exceptional at processing high volumes of data, it lacks the ethical and logical framework to consistently identify its own hallucinations. By implementing a HITL approach, subject matter experts can review AI-generated responses, code, or security alerts before they are acted upon. This human oversight allows for the identification of "logical leaps" or false information that automated filters might miss.
Whiledeep fakes(Option B) are typically addressed through cryptographic watermarking or origin tracking, andphishing(Option C) is mitigated via email security gateways and user training, hallucinations are an inherent flaw in the model's predictive nature that requires manual verification.Scale changes(Option D) refer to technical image manipulations and are not a primary concern for HITL policies. Incorporating human feedback-often throughReinforcement Learning from Human Feedback (RLHF)-allows the security infrastructure to refine the model's accuracy over time, ensuring that generative outputs remain reliable, safe, and aligned with organizational standards.


NEW QUESTION # 47
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: B

Explanation:
In a modern cloud and campus environment, managing the lifecycle of an identity is the cornerstone of a secure architecture.Identity and Access Management (IAM)is the comprehensive framework of policies and technologies that ensures the right individuals have the appropriate access to technology resources. According to the Cisco SDSI objectives, IAM is the primary mechanism used to transition from manual, error-prone onboarding to a policy-driven approach based onroles and responsibilities.
IAM solutions allow administrators to define digital identities and associate them with specific roles (Role- Based Access Control). When a new employee is onboarded, the IAM system automatically provisions access to the necessary cloud applications and data based on their department or job function. This ensures the principle ofleast privilegeis maintained from day one. WhileSecurity Groups(Option B) andNetwork Access Control Lists (ACLs)(Option D) are important technical controls for filtering traffic at the network layer, they do not manage the identity lifecycle or the complex mapping of users to application permissions. A VPN(Option C) provides a secure tunnel for remote access but does not definewhata user can do once they are inside the network. IAM provides the central control plane for identity-centric security, which is essential for a large university environment with high user turnover and diverse access requirements.

NEW QUESTION # 48
Network administrators at a medical facility cannot log in to network devices because of excessive resource consumption and high CPU utilization. The situation has led to delays in routine maintenance and troubleshooting, which affects overall network performance. An engineer must optimize the handling of traffic to reduce the impact and maintain consistent access and operational efficiency. Which approach must be implemented to meet the requirement?

Answer: B

Explanation:
The scenario described-where high CPU utilization prevents administrators from accessing device management interfaces-is a classic indication that the device'sControl Planeis being overwhelmed by malicious or malformed traffic (such as a DoS attack or a routing loop). To protect the "brains" of the network device,Control Plane Policing (CoPP)must be implemented.
CoPP allows an engineer to define filter and rate-limit policies specifically for traffic destined for the CPU.
By categorizing traffic into different classes (e.g., routing protocols, management traffic like SSH, and "catch- all" untrusted traffic), CoPP ensures that critical management and control traffic is prioritized while excessive or suspicious traffic is dropped before it can impact the device's performance. This maintainsoperational efficiencyeven during a traffic spike or attack. WhileAAA(Option B) handles authentication andRBAC (Option D) manages permissions once a user is logged in, neither can prevent the CPU exhaustion that blocks the login attempt in the first place.SNMP(Option C) is used for monitoring but does not provide active traffic policing. Within the Cisco SDSI framework, CoPP is a fundamental "Self-Defending Network" feature required to ensure the availability and resilience of the core infrastructure.
