Cisco Designing Cisco Security Infrastructure Sample Questions (Q12-Q17):

NEW QUESTION # 12
How does a SOC leverage flow collectors?

Answer: A

Explanation:
Aflow collector(such asCisco Secure Network Analytics, formerly Stealthwatch) is a critical tool within a Security Operations Center (SOC) for providing "pervasive visibility" into the network. Instead of capturing every full packet-which is resource-intensive-a flow collector ingests NetFlow or IPFIX data, which contains metadata like source/destination IPs, ports, and the volume of data transferred.
The SOC leverages this data forthreat detection and responseby establishing a baseline of normal network behavior. When a flow collector identifies an anomaly-such as an endpoint suddenly sending gigabytes of data to an unusual external IP (data exfiltration) or scanning internal ports (lateral movement)-it flags the incident for analysis. UnlikeReal-time content filtering(Option D), which happens at the gateway (e.g., Cisco Umbrella or WSA), flow collectors provide a historical record and behavioral analysis ofallinternal and external traffic. They do not performload balancing(Option B) orbackup/recovery(Option A). In the Cisco SDSI framework, flow analysis is essential for identifying the "unknown unknowns" and providing the forensic evidence needed to understand the scope and path of a security breach.


NEW QUESTION # 13
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: A

Explanation:
In the context of theCisco Security Infrastructure (300-745 SDSI)objectives, ensuringdata integrityis a fundamental requirement, particularly in the healthcare sector where the accuracy of medical records at remote sites is critical for patient safety.Hashingis the primary mathematical process used to verify that data has not been altered or tampered with during transit between locations.
Hashing works by applying a cryptographic algorithm (such as SHA-256) to a data set to produce a fixed-size string of characters called a "hash" or "checksum." When data is sent from one remote site to another, the sender calculates a hash of the original data. Upon arrival, the receiving site recalculates the hash using the same algorithm. If the two hashes match exactly, the receiver is assured that the data is identical to the original and has maintained its integrity. Even a single-bit change in the original data would result in a completely different hash value.
WhileAuthentication(Option D) andPreshared Keys(Option C) are essential for verifying the identity of the sites and establishing secure tunnels (like IPsec VPNs), they do not, by themselves, provide the mathematical proof of content integrity.Data Masking(Option B) is a privacy technique used to hide sensitive information from unauthorized viewers, but it does not prevent or detect data corruption or unauthorized modifications.
Therefore, hashing is the specified technical control for achieving verifiable data integrity across distributed infrastructures.


NEW QUESTION # 14
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: B

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.


NEW QUESTION # 15
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: A

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 # 16
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: A

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.
