NEW QUESTION # 14
An agricultural company wants to enhance the cybersecurity posture by implementing a defense- in-depth strategy to protect against polymorphic malware threats. Currently, the company's security infrastructure relies solely on a stateful traditional edge firewall that does not provide adequate protection against malware variants. Which technology must be added to the company's security architecture to achieve the goal?
Answer: D
Explanation:
A heuristics-based Intrusion Prevention System (IPS) analyzes traffic behavior and patterns, allowing it to detect and block polymorphic malware that constantly changes its signature to evade traditional defenses. Adding this technology strengthens the company's defense-in-depth strategy beyond the limitations of a stateful firewall.
NEW QUESTION # 15
A pharmaceutical company needs a hub-and-spoke VPN topology. The design must be capable of building either partial or full mesh overlay networks. Which VPN solution must be implemented in the environment?
Answer: D
Explanation:
In the context of theDesigning Cisco Security Infrastructure (300-745 SDSI)blueprint,Dynamic Multipoint VPN (DMVPN)is the specialized architectural solution designed for scalable hub-and-spoke topologies that require the flexibility to evolve into partial or full mesh overlays. DMVPN leverages a combination of Multipoint GRE (mGRE) tunnels, Next Hop Resolution Protocol (NHRP), and IPsec encryption to create a dynamic environment.
The primary advantage of DMVPN is its ability to establish "on-demand" tunnels between spoke sites. In a traditional hub-and-spoke model, traffic between two spokes must transit the hub, which introduces latency and increases hub resource consumption. With DMVPN, spokes can use NHRP to discover the public IP addresses of other spokes and build direct tunnels between them automatically. This allows the pharmaceutical company to maintain a simple hub-and-spoke management model while benefiting from the performance of afull meshwhen traffic patterns demand it.
WhileSSL VPNs(Option D) andL2TP(Option B) are excellent for individual remote access, they are not designed for site-to-site mesh scalability.Crypto maps(Option C) represent the legacy method of building IPsec tunnels, which requires static, manual configuration of every peer relationship-making a full mesh practically impossible to manage at scale. DMVPN fulfills the Cisco SDSI objective of designing highly available and flexible secure infrastructure by automating the complexity of large-scale tunnel management.
NEW QUESTION # 16
Which tool is used to collect, analyze, and visualize logs from network devices, endpoints, and other sources in an enterprise?
Answer: C
Explanation:
Splunk is a SIEM and log management tool used to collect, analyze, and visualize logs from diverse sources such as network devices, endpoints, and applications. It provides centralized visibility for security monitoring and incident response.
NEW QUESTION # 17
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: A
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.

NEW QUESTION # 18
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: D
Explanation:
802.1X provides port-based network access control, requiring devices (wired or wireless) to authenticate before gaining network access. This ensures that only authorized users and devices can connect, enforcing the BYOD policy and preventing unauthorized wired connections.
