An organization is designing a customer-facing web service that runs on several virtual machines behind a load balancer. Management insists that the application must keep functioning even if one server crashes or a software bug causes a container to fail. Within a high-availability architecture, which term best describes the ability of the system to continue operating under these component-level failures?
The act of encrypting data to protect it from unauthorized access during transmission.
The geographical diversity of redundant systems to prevent localized disasters from causing data loss.
The frequency at which system backups are performed to prevent data loss.
The capacity of a system to maintain function despite failures or challenges to its components.
Resilience is the capacity of a system to maintain its intended function when individual hardware or software components fail. By contrast, backup frequency concerns data protection schedules, encryption focuses on confidentiality during transit, and geographic redundancy is a specific strategy-one of many-that can contribute to resilience but does not define the overarching concept.
