Cisco Designing Cisco Security Infrastructure Sample Questions (Q29-Q34):

NEW QUESTION # 29
A developer company recently made a contract with new customer in the financial space. The customer has multiple remote sites and requires a VPN solution with the highest encryption.
Which protocol must be used in IPsec Phase 2?

Answer: B

Explanation:
In IPsec Phase 2, the Encapsulating Security Payload (ESP) protocol is used to provide confidentiality, integrity, and authentication for VPN traffic. ESP ensures the highest encryption and protection for sensitive financial data across remote sites.


NEW QUESTION # 30
A technology company recently onboarded a new customer in the medical space. The customer needs a solution to provide data integrity across remote sites. Which solution must be used to meet this requirement?

Answer: D

Explanation:
Hashing ensures data integrity by generating a fixed-length value (hash) for data. When data is transmitted between remote sites, the hash can be recalculated and compared to verify that the data has not been altered in transit.


NEW QUESTION # 31
An oil and gas company recently faced a security breach when an employee's notepad, which contained critical login credentials, was stolen. The incident led to unauthorized access to a user account, which posed a significant risk to sensitive company data and operations. The company wants to adopt a security measure that enhances user account protection. Which action must be taken to prevent breaches like this from happening in the future?

Answer: B

Explanation:
The scenario described-where physical theft of written credentials led to a breach-is a classic failure of single-factor authentication. To mitigate this risk, the company must implementMulti-Factor Authentication (MFA). MFA requires users to provide two or more verification factors to gain access to a resource, typically categorized as something you know (password), something you have (a smartphone or hardware token), or something you are (biometrics).
According to Cisco Security Infrastructure design best practices, MFA (such asCisco Duo) ensures that even if an attacker possesses valid credentials (the "something you know" from the stolen notepad), they cannot gain access without the second factor (the "something you have"). This effectively neutralizes the threat of stolen passwords.Single Sign-On (SSO)(Option B) improves user experience and centralizes management but does not, by itself, stop an attacker who has the master password.Updating the RADIUS server(Option C) is a maintenance task that doesn't change the authentication logic, and apassword expiration policy(Option D) would only limit the "shelf life" of the stolen credentials rather than preventing their initial use. MFA is the most robust architectural control for enhancing identity security and is a core pillar of a Zero Trust framework.

NEW QUESTION # 32
Which generative AI impact is addressed by a human-in-the-loop design policy?

Answer: B

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 # 33
A restaurant distribution center recently suffered a password spray attack targeting the Cisco Secure Firepower Threat Defense VPN headend. The attack attempts to gain unauthorized access by trying common passwords across many accounts. The attack poses a significant security threat to the organization's remote access infrastructure. To enhance the security of VPN setup and minimize the risk of similar attacks in the future, the IT security team must implement effective mitigation measures. Which technique effectively reduces the risk of this type of attack?

Answer: B

Explanation:
Enabling AAA authentication on the default connection profiles ensures that all VPN access attempts must go through strong authentication. This directly mitigates password spray attacks by enforcing centralized authentication controls, enabling account lockout, and supporting additional protections such as multifactor authentication.
