CV0-004 Exam Dumps : CompTIA Cloud+ (V4)

The Reserved resources model offers cost savings for committed use over a long term, which can reduce costs while maintaining performance for predictable workloads. The Spot instance model allows users to take advantage of unused capacity at lower prices, offering significant cost savings, though with the possibility of instances being terminated when demand rises. Both models can be strategically used to optimize costs without compromising performance.

For volumetric DDoS, the primary goal is to absorb and disperse massive traffic floods before they overwhelm bandwidth, edge links, or the application entry point. Placing a CDN in front of the web server is highly effective because CDN edge nodes distribute traffic globally, cache static content, and reduce direct requests reaching the origin. This improves resilience and keeps origin capacity available for legitimate users. A WAF complements this by filtering malicious HTTP/S traffic patterns and enforcing rules (rate limiting, bot filtering, request validation) at the edge or in front of the service. Together, CDN + WAF align with Cloud+ CV0-004 objectives around designing secure, highly available architectures, implementing layered defenses, and using cloud-native services to mitigate attacks.

DLP focuses on preventing data exfiltration, not DDoS. Hardening reduces compromise risk but does not stop traffic floods. ACLs can restrict known bad sources but are limited against distributed botnets and may not scale fast enough for large attacks. Inline IDS is typically detection-focused and can become a bottleneck during volumetric events.

Remote replication for failover is the data protection strategy that should be used to back up on-premises data to the cloud for an earthquake-prone location. It provides real-time or near-real-time copying of data to a remote location, which can be quickly activated in case the primary site fails.

Disaster recovery strategies, including remote replication for failover, are part of the cloud-based data protection methods covered in the CompTIA Cloud+ certification.
