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

When migrating a highly available application normally hosted on a local VM cluster for usage with an external user population, the best migration type would be on-premises to cloud. This allows the application to leverage the cloud's scalability and reach, providing better access to the external users.

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.

A branch is the best option because it allows a development team to maintain separate lines of development from a shared codebase. In CompTIA Cloud+ (CV0-004) objectives related to DevOps practices, version control, and configuration management, branching strategies are used to support multiple feature sets, releases, and customer-specific customizations without disrupting the primary (main) code line. For example, a team can create a branch per client, per release version, or per feature set, enabling isolated development and testing while still inheriting common fixes and improvements from the main branch when appropriate. This is especially useful when different customers require different configurations or optional modules in the same product.

A commit is simply a recorded change to code within a branch; it doesn’t provide separation for different client versions by itself. A push sends committed changes to a remote repository but also doesn’t address parallel code management. A merge combines branches back together, which is often done after changes are validated, but it is not the mechanism for maintaining separate client-specific variations. Therefore, branching best meets the requirement.
