An Intrusion Prevention System is designed to inspect traffic and actively stop malicious activity before it reaches protected systems. The key distinction is prevention: an IPS can block, drop, reset, or otherwise filter traffic that matches known exploit patterns, malicious signatures, protocol anomalies, or policy violations. Answer A describes detection, which is closer to the function of an IDS. An IDS monitors and alerts, while an IPS operates inline and can enforce a blocking decision. Building code for server infrastructure and deploying scanners are not IPS functions. In practice, IPS capabilities are often integrated into next-generation firewalls so that threat prevention occurs at network enforcement points. IPS is especially important for reducing exploit exposure against servers, applications, and internal systems because it can interrupt attacks in transit. However, IPS does not replace patching; it reduces risk while vulnerabilities are being fixed or when unknown exposure exists.

Two of the four Cs of cloud-native security are Code and Clusters. The four-Cs model is commonly used to organize cloud-native security responsibilities across layers: cloud, cluster, container, and code. Code is the application logic and dependencies that developers produce, and it must be secured through review, scanning, dependency management, and secrets control. Cluster refers to the orchestration environment that runs workloads, commonly Kubernetes, and must be secured through access control, configuration hardening, network policy, and runtime monitoring. Configurations are extremely important in cloud security, but “Configurations” is not one of the four Cs in this model. Connections are also important, especially for service communication and network policy, but they are not one of the named four Cs. The model is useful because cloud-native risk is layered: weak code, vulnerable containers, misconfigured clusters, or insecure cloud infrastructure can each become an attack path.

DHCP provides IP addressing information to a client. When a device joins a network, it can request configuration from a DHCP server instead of requiring manual assignment. The server leases an IP address to the client and may also provide subnet mask, default gateway, DNS server, lease duration, and other options. DHCP does not provide a MAC address; the MAC address is assigned to the network interface by the hardware vendor. It does not provide a security zone, which is a firewall or segmentation concept. It also does not assign a port range in the normal client addressing process. DHCP is important operationally because it reduces manual configuration and supports scalable network management. It is also useful in investigations because DHCP lease records can help map an IP address observed in logs to the device that used it at a specific time.

An API, or application programming interface, allows software applications and services to communicate and share data in a structured way. APIs define how requests are made, what data formats are accepted, what operations are available, and how responses are returned. In cloud and modern application environments, APIs are fundamental because applications often rely on microservices, third-party integrations, identity providers, automation tools, and cloud management platforms. APIs do not allow operating systems to redesign themselves. They are not specifically for machine learning models to check datagrams, and they are not primarily hardware modification controls. From a security perspective, APIs must be protected because they expose application functions and data paths. API security includes authentication, authorization, rate limiting, input validation, logging, and secrets protection. If poorly secured, APIs can expose sensitive data or allow unauthorized actions.
