Identifying potential security threats requires actively watching for the specific indicators that signal malicious or unauthorized activity is being attempted, and tracking unauthorized access attempts, failed logins, denied authorization requests, access from unexpected locations or at unusual times, provides direct, actionable evidence of exactly this kind of threat activity as it occurs or is attempted, making it the correct and specifically threat-focused monitoring target for a cybersecurity team. This kind of tracking allows the team to detect intrusion attempts, credential stuffing, or privilege escalation efforts early, often before they succeed. Configuring multiple network ports (A) is an infrastructure configuration action, not a monitoring or threat-identification activity at all, and does not fit the question's framing of what the team should 'monitor.' Reducing the number of personnel with access (B) is a preventive access-management control that limits the attack surface in advance, a good governance practice, but it is an action taken to reduce risk, not something to monitor for threat identification purposes. Focusing on user activity logs (C) is related and useful, since access attempts are often captured within activity logs, but it is broader and less precisely targeted than specifically tracking unauthorized access attempts, which is the more specific, directly threat-relevant signal the cybersecurity team should prioritize. Tracking unauthorized access attempts is correct.

A local disaster such as fire or flood is, by definition, geographically confined; it damages or destroys everything physically present at the affected site, regardless of how many separate devices or storage systems are located there. The only way to guarantee that a copy of the data survives such an event is to ensure that at least one copy exists somewhere geographically removed from the risk, either at a genuinely remote physical site or in a cloud provider's data center located outside the affected area. This satisfies the core disaster recovery principle that protection copies must not share fate with the primary site. Storing backup data on the same device as the original (B) provides no protection at all against any failure, let alone a site-wide disaster, since both copies would be destroyed simultaneously. Immediately archiving all backup data (C) does not address geography and, if the archive remains on-site, offers no protection against fire or flood either. Backing up to another storage system in the same location (D) improves protection against device-level failure but does nothing against a site-wide event that would damage all on-site equipment together. Keeping backups only locally (E) is the opposite of what the scenario requires. Remote or cloud storage is correct.

Graceful degradation is a resiliency design principle in which an application is deliberately architected so that, when a component or dependency fails, non-essential features are automatically disabled or scaled back while core functionality continues to operate, rather than the entire application failing outright. This precisely matches the scenario's requirement: continuing to function, albeit with reduced capability, in the face of a component failure, rather than pursuing either full failure or full recovery as the only two outcomes. Virtualized servers (B) provide a flexible, abstracted compute platform and can support many resiliency techniques, but virtualization itself is an infrastructure choice, not a design principle that dictates how an application behaves during partial failure. Fault detection and retry logic (C) is a technique for automatically retrying a failed operation, often useful for transient faults, but it does not describe reduced-functionality continuation; a retry either succeeds (full functionality resumes) or continues failing, without an intermediate degraded-but-operational state. Stateless design (D) allows any server instance to handle any request without relying on session-specific local state, which supports horizontal scaling and easier failover, but does not itself describe reduced functionality during a failure. Graceful degradation directly and specifically addresses the described goal.

RAID combines multiple physical disks into a single logical unit using techniques such as striping, mirroring, and parity, which simultaneously delivers two benefits relevant to this scenario: redundancy against one or more drive failures (through mirrored or parity-protected data) and improved read/write performance (through striping data across multiple drives, which allows parallel I/O operations). Certain RAID levels, such as RAID 10, are specifically chosen when both protection and performance are priorities, making RAID the technique that directly satisfies both stated requirements simultaneously. Content Delivery Networks (B) are a technique for caching and distributing web content geographically closer to end users to reduce latency; they have no relationship to protecting against local disk drive failures within a storage system. High availability clusters (C) provide failover between entire servers or nodes at a much higher architectural level than individual disk drives, and while valuable for system-level resiliency, they do not specifically describe the disk-level redundancy and performance mechanism the scenario is asking about. A cold spare (D) is a standby replacement drive kept ready but not actively participating in I/O, requiring manual or automated intervention to swap in after a failure; it does not provide the ongoing performance improvement RAID delivers through active striping. RAID is correct.
