Monitoringcapacity utilizationsupportsavailabilityby ensuring thatresources remain functional and do not exceed operational limits.
* Option A (Incorrect):Integrityensures that data isaccurate and unaltered, but monitoring capacity thresholds primarily relates tosystem availability.
* Option B (Correct):Availabilityensures that systems remainaccessible and functional, and monitoring capacity utilization helpsprevent downtimeandservice disruptions.
* Option C (Incorrect):Confidentialityensures that data isprotected from unauthorized access, which is unrelated to capacity monitoring.
* Option D (Incorrect):Nonrepudiationensures that actions can betraced to specific individuals, but it does not relate tocapacity monitoring.

Machine shredding is the process of using a shredding machine to physically destroy the media and make the data unrecoverable. This is more effective than software formatting, which only erases the data logically and may leave traces that can be recovered by special tools1. Encrypting and destroying keys may prevent unauthorized access to the data, but it does not erase the data from the media. Wiping and rewriting three times is unnecessary and may reduce the lifespan of the media, especially for solid state drives2. Machine shredding is also recommended by various security standards and guidelines for media disposal345.

Backup procedures for an organization's critical data are considered to be corrective controls, as they are designed to restore normal operations after a disruption or failure. Corrective controls aim to minimize the impact of an incident and prevent recurrence. Directive, detective and compensating controls are not related to backup procedures. Directive controls are intended to guide or instruct users to follow policies and procedures. Detective controls are intended to identify and report incidents or violations. Compensating controls are intended to mitigate the risk of a missing or ineffective primary control. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.11

Limiting the rate of incoming requests, known as rate limiting, helps prevent API overloading by controlling the number of requests a client can make within a specific timeframe. This measure protects the API from being overwhelmed, ensuring better availability and performance. While dedicated servers, continuous integration/deployment, and stress testing contribute to overall system robustness, rate limiting directly addresses the risk of unavailability due to excessive or malicious traffic.
