20+ practice questions focused on Cloud Architecture and Design — one of the most tested topics on the CompTIA Cloud+ CV0-004 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Cloud Architecture and Design PracticeA company is migrating a legacy on-premises application to a public cloud. The application currently uses a single monolithic architecture and relies on a local file system for storage. The cloud architect needs to redesign the application to take advantage of cloud-native features. Which design principle should the architect prioritize to ensure scalability and resilience?
Explanation: Option C is correct because refactoring the monolithic application into microservices enables independent scaling of components, improves fault isolation, and aligns with cloud-native patterns like containerization and orchestration (e.g., Kubernetes). This approach leverages horizontal scaling across multiple instances, which is essential for achieving elasticity and resilience in a public cloud environment, unlike the legacy single-point-of-failure monolithic design.
A cloud architect is designing a multi-tier web application in a cloud environment. The application must handle unpredictable traffic spikes while minimizing costs. The architect decides to use auto-scaling groups for the web tier and a managed database service for the data tier. Which additional design consideration is MOST important to ensure the application remains available during a regional outage?
Explanation: Distributing the auto-scaling group across multiple Availability Zones (AZs) ensures that if one AZ fails, the web tier continues to serve traffic from the remaining AZs. This is the most critical design consideration for maintaining availability during a regional outage because it provides fault isolation at the AZ level, which is a fundamental principle of high availability in cloud architecture.
A company is deploying a critical financial application on a private cloud. The compliance team requires that all data at rest be encrypted with a key managed by the company's hardware security module (HSM). The cloud architect must select a storage solution that supports customer-managed keys and integrates with the existing HSM. Which storage option should the architect choose?
Explanation: Option C is correct because a software-defined storage (SDS) cluster can be configured to use customer-managed encryption keys that integrate directly with the company's existing hardware security module (HSM) via standard interfaces like PKCS#11 or KMIP. This allows the company to maintain full control over key management and meet the compliance requirement for data-at-rest encryption with HSM-managed keys.
A cloud engineer is troubleshooting a performance issue in a virtualized environment. A critical application is running slowly, and the engineer suspects resource contention. The host server has 32 vCPUs and 256 GB of RAM, running four VMs. Which tool should the engineer use to determine if CPU ready time is causing the performance degradation?
Explanation: CPU ready time is a hypervisor-level metric that measures the time a VM is ready to execute but must wait for a physical CPU core to become available. Since the engineer suspects resource contention among VMs on the same host, the hypervisor's monitoring console (e.g., vSphere, Hyper-V Manager) is the only tool that can expose this metric directly. Guest OS tools like 'top' or Performance Monitor cannot see CPU ready time because it occurs at the virtualization layer, not inside the VM.
A cloud architect is designing a disaster recovery plan for a cloud-based application. The primary site is in a cloud region, and the recovery site is in a different geographic region. The application uses a relational database with synchronous replication. The recovery time objective (RTO) is 1 hour, and the recovery point objective (RPO) is 15 minutes. Which replication strategy BEST meets these objectives?
Explanation: Synchronous database replication with automated failover ensures that every write transaction is committed to both the primary and recovery site databases before acknowledging success, guaranteeing zero data loss (RPO=0) and near-instantaneous failover within seconds to minutes, which comfortably meets the RTO of 1 hour and RPO of 15 minutes. This strategy directly satisfies the strict RPO requirement by maintaining a fully synchronized, hot standby replica that can be promoted immediately upon failure.
