NEW QUESTION # 60
Employees in a healthcare organization could not access their devices when they returned to work after the weekend. The security team discovered that a threat actor had encrypted the devices. Which security solution would mitigate the risk in future?
Answer: C
Explanation:
In the scenario described, the healthcare organization fell victim to aransomware attack, where devices were encrypted to extort the organization. To mitigate such risks in the future,Endpoint Detection and Response (EDR)is the essential architectural component. According to the Cisco SDSI Secure Infrastructure domain, protecting endpoints requires more than just traditional antivirus; it necessitates a solution that provides deep visibility into file behavior and process execution.
A robust EDR solution, such asCisco Secure Endpoint, continuously monitors all activity on the device.
When ransomware attempts to initiate its encryption process, the EDR can detect the malicious behavioral pattern in real-time. It can then take automated actions, such as isolating the infected host from the network and "stopping" the encryption process before it spreads. Furthermore, Cisco's EDR providesretrospective security, allowing administrators to see how the malware arrived and which other devices it touched. While Option A (Password Policies) helps prevent credential theft and Option C (DLP) prevents data theft, they do not stop the technical process of disk encryption. Only EDR provides the necessary detection and automated response capabilities to handle modern file-less and polymorphic malware threats effectively. This aligns with the Cisco SAFE goal of securing the endpoint layer against advanced persistent threats (APTs) and ransomware variants.

NEW QUESTION # 61
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: A
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 # 62
A construction company recently introduced a BYOD policy, where contractors can bring personal devices and connect to the wireless network. The network engineer configured a Wi-Fi network with a guest splash page to provide internet access only. Although the policy was limited to wireless devices, contractors started bringing devices that needed wired connections without authorization and connecting to the network. The network team suggested shutting down ports where unauthorized devices are connected. Which technology must be implemented to ensure that wired and wireless devices are granted network access only after successful authentication?
Answer: A
Explanation:
To secure both wired and wireless access points against unauthorized devices, the industry-standard framework isIEEE 802.1x. This technology provides port-based network access control (PNAC), ensuring that no traffic-wired or wireless-is forwarded by the switch or access point until the device or user has been successfully authenticated by a central authority, typically a RADIUS server likeCisco Identity Services Engine (ISE).
In an 802.1x architecture, the device (Supplicant) must provide valid credentials or certificates to the switch
/AP (Authenticator). The Authenticator then communicates with the Authentication Server to verify the identity. If authentication fails, the port remains in a "closed" state, effectively preventing the unauthorized
"rogue" wired connections mentioned in the scenario. This approach is far more scalable and dynamic than manually shutting down ports or usingVACLs(Option C), which are static filters based on IP or MAC addresses.VxLANs(Option A) are used for network virtualization and overlay tunneling, whilePrivate VLANs(Option B) provide Layer 2 isolation within a subnet but do not verify identity. By implementing
802.1x, the construction company establishes a robust "gatekeeper" at the hardware level, satisfying the Cisco SDSI objective of securing the network edge through identity-based access control for a diverse set of devices.

NEW QUESTION # 63
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: C
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 # 64
A healthcare organization in the United States recently discovered that a highly confidential report name Records ______ that includes patient records name Patient_Medical_Records _____ was accessed by unauthorized personnel internally. The breach occurred due to lack of protection measures in place for patient electronic medical records. Which regulatory compliance is directly appropriate and must be adopted?
Answer: B
Explanation:
The Health Insurance Portability and Accountability Act (HIPAA) is the U.S. regulation that governs the protection of patient medical records and electronic health information. Since the breach involved unauthorized access to patient medical records, HIPAA compliance is directly required.
