          Correct Answer: 1<\/b><\/p>\n

          Explanation:<\/b><\/p>\n

          DHCP snooping is a Layer 2 security technology built into enterprise switches that acts as a firewall between untrusted host devices and trusted DHCP servers. When enabled, DHCP snooping intercepts DHCP traffic, drops malicious DHCP server replies originating from untrusted ports, and builds a dynamic binding database tracking client IP addresses, MAC addresses, switch ports, and VLANs. This database is subsequently utilized by advanced features like Dynamic ARP Inspection and IP Source Guard to ensure comprehensive Layer 2 network integrity and prevent rogue server attacks that could otherwise redirect default gateways or facilitate man-in-the-middle exploits across campus environments.<\/span><\/p>\n

          Question 325<\/b><\/h3>\n

                              Correct Answer: 2<\/b><\/p>\n

                              Explanation:<\/b><\/p>\n

                              Unicast Reverse Path Forwarding (uRPF) is a security and routing feature implemented on Cisco network devices to mitigate problems caused by malicious or accidental IP address spoofing. When uRPF is enabled on an interface, the router examines incoming packets and checks its routing table to determine if the packet arrived on the optimal interface back to the source IP address. If the packet arrives on an unexpected interface or if no valid routing entry exists for that source IP, the router drops the packet. This prevents attackers from launching spoofed DoS attacks or bypassing perimeter access controls.<\/span><\/p>\n

                                      Correct Answer: 4<\/b><\/p>\n

                                      Explanation:<\/b><\/p>\n

                                      A hardware Trust Anchor or Trusted Platform Module provides an immutable hardware-based foundation for system security. During device startup, Secure Boot utilizes cryptographic keys stored in the hardware trust anchor to verify the digital signature of operating system boot loaders and firmware images. If any component has been tampered with or modified maliciously, the device halts the boot process, preventing compromised firmware execution. This hardware-level validation guarantees that the underlying platform has not been subverted by rootkits or persistent firmware implants.<\/span><\/p>\n

                                        Correct Answer: 1<\/b><\/p>\n

                                        Explanation:<\/b><\/p>\n

                                        The SIEM event collection and normalization engine is a foundational data ingestion pipeline within a Security Information and Event Management platform where raw, unstructured log messages from diverse vendor systems are dissected and standardized. Parsing extracts specific attributes such as source IP, username, and event ID, while normalization maps these fields into a unified schema, enabling efficient event correlation and multi-vendor threat analysis. This ensures security analysts can review standardized events across heterogeneous operating systems and network devices without syntax confusion.<\/span><\/p>\n

                                          Correct Answer: 3<\/b><\/p>\n

                                          Explanation:<\/b><\/p>\n

                                          Separation of duties is a foundational internal control and governance principle designed to prevent fraud, errors, and malicious activities by ensuring that no single individual maintains end-to-end control over a critical operational or financial transaction. By dividing sensitive workflows\u2014such as financial authorizations, code deployments, or cryptographic key management\u2014across multiple distinct roles, organizations enforce accountability and require collusion for malicious actions to succeed, significantly enhancing enterprise security posture and compliance alignment.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
