Exam CCSP topic 1 question 300 discussion

D is correct

Automation → Detects failures and triggers mitigation processes dynamically (e.g., spinning up new instances, rerouting traffic, restarting failed services). Fault Tolerance → Prevents failures from impacting operations by designing systems that continue running despite failures (e.g., using redundant components, error correction, failover mechanisms).The question specifically asks for a concept that pertains to detecting problems and invoking redundant systems or processes for mitigation. Automation actively monitors the system, detects issues, and initiates mitigation actions (like provisioning additional resources or rerouting traffic). Fault Tolerance is about system design, ensuring that failures do not impact operations by having built-in redundancy (e.g., RAID storage, dual power supplies, load-balanced clusters). It does not actively detect issues or invoke recovery mechanisms programmatically—it simply ensures the system keeps running despite failures.

Modern web service systems are designed with high availability and resiliency, and automation plays a key role in detecting issues and triggering mitigation processes programmatically. Automated monitoring and recovery mechanisms ensure that when a failure or issue is detected, the system can automatically invoke redundant systems or recovery actions without manual intervention. Why Not the Others? A. Elasticity → Refers to scaling resources up or down dynamically based on demand but does not necessarily involve failure detection or recovery. B. Redundancy → Ensures backup systems exist, but redundancy alone does not detect failures or trigger recovery actions. C. Fault Tolerance → Ensures a system can continue operating despite failures, but it does not include the detection and automated response aspect that automation provides.

A stupid question!

Please take down this dump! It’s very useless. Don’t waste your time going through it!!
