Security controls are classified by the point in the threat lifecycle at which they act. A swipe card system physically blocks entry to a restricted area unless the presenter holds valid, authorized credentials; the control acts before an unauthorized event occurs, stopping the access attempt outright, which is the defining characteristic of a preventive control. A deterrent control (A) works psychologically, discouraging an attempt through visible consequence or risk (a warning sign or visible camera housing) without physically stopping access, so it is a weaker classification for a badge-reader-controlled door than preventive. A detective control (D) identifies that an event has already happened, such as a log showing a failed badge swipe or an alarm triggered after entry, but does not itself stop the entry. A corrective control (C) acts after an incident to restore normal operations or limit damage, such as revoking a compromised badge or resetting a lock. Because the swipe card system's core function is to block unauthorized physical access before it happens, it is correctly categorized as a preventive control within the standard deterrent-preventive-detective-corrective framework used in data protection security management.

Many compliance and regulatory frameworks require organizations to demonstrate that they maintain reliable, recoverable copies of critical data, along with defined recovery capabilities in case of data loss or corruption. Local replication, creating point-in-time copies such as clones or snapshots within the same storage system or site, directly supports this requirement by providing an additional, readily available, reliable copy of production data that can be used for rapid recovery, testing, or reporting purposes without impacting the primary production dataset, which collectively constitutes a demonstrable, reliable data protection solution auditors and compliance frameworks look for. Among the given options, this general characterization of reliable, dependable data protection capability most directly explains why local replication supports compliance objectives. Enabling faster data migration (A) describes a potential operational use case for replication technology, but it is not itself a compliance-driven benefit or requirement that organizations are typically evaluated against. Reducing the overall data footprint (B) is inaccurate, since local replication technologies such as full-volume mirrors or clones typically increase total storage consumption by creating additional copies of data, rather than reducing it. Simplifying data encryption processes (C) is unrelated to what local replication technology does; replication and encryption are separate, independent data protection mechanisms, and replicating data does not inherently simplify or affect how encryption is applied. Providing a reliable data protection solution is correct.

Agent-based backup requires installing backup software directly onto the application server being protected, and that agent then consumes local CPU, memory, and I/O resources to scan, read, and transmit data as part of the backup job, resources that are simultaneously needed by the production application running on the same server. This direct resource contention on the same host is exactly what the scenario describes, the backup process consuming significant system resources and degrading application responsiveness, and it is a well-documented and specific drawback of agent-based backup architectures compared to approaches that offload processing elsewhere. Using a network-based protocol (A) describes how data moves across the network and is not inherently tied to consuming local server compute resources; network-based backup can, in fact, be combined with offloaded, agentless techniques that minimize host impact. Image-based backups for VMs (B) typically operate at the hypervisor layer using snapshot technology, which is specifically designed to minimize impact on the guest operating system and its applications, making it a technique that reduces this exact problem rather than causes it. Backing up directly from primary storage (C) can create load, but the scenario specifically points to resource consumption on the application servers themselves, which is characteristic of an installed agent, not of storage-side backup access. The agent-based approach is correct.

Data protection applications, the management software and interfaces used to configure, run, and monitor backup, replication, and recovery operations, are themselves potential attack surfaces, since compromising them can grant an attacker the ability to disrupt or exfiltrate protected data at scale. Two controls that directly reduce this application-layer risk are identity and access management, which limits who can authenticate to the application and what actions they are authorized to perform, and the regular installation of security updates, which closes known vulnerabilities in the application's code before they can be exploited. Together these address both the authorization and the technical vulnerability dimensions of application security. Physical security controls (B), such as CCTV and badge access, protect the physical premises and hardware but do nothing to prevent a remote attacker from exploiting an application vulnerability or a compromised credential over the network. Encrypting data and shipping it offsite (C) and remote replication to various storage types (D) are both data resiliency and confidentiality measures for the data itself, addressing loss or disclosure of the underlying dataset, not the security posture of the management application that orchestrates these processes. IAM combined with patching correctly targets the application layer.
