CompTIA Cloud+ (CV0-004) — All Questions

A team wants every deployment of its network and compute resources to be reproducible, version-controlled, and auditable. Which approach best achieves this?

• a.Manually configuring resources through the web console each time
• b.Emailing a checklist of steps to the operations team
• c.Defining infrastructure as code in declarative templates✓
• d.Taking screenshots of the settings after each build

Infrastructure as code (IaC) defines resources in declarative, version-controlled templates so environments can be rebuilt identically and reviewed like any other code. Manual console changes and checklists are error-prone and not reliably reproducible or auditable.

A company moves an existing application to the cloud with no changes to its architecture, simply relocating the VMs. Which migration strategy is this?

• a.Lift-and-shift (rehost)✓
• b.Refactor (re-architect)
• c.Replatform
• d.Retire

Lift-and-shift, or rehosting, moves a workload to the cloud as-is with minimal changes, which is fast but does not gain cloud-native benefits. Replatforming makes small optimizations, refactoring redesigns the application, and retiring removes it entirely.

An administrator is subnetting a VPC and must place a database tier where instances have no direct route to the internet. Which design element accomplishes this?

• a.Assigning public IP addresses to each database instance
• b.Placing the databases in a public subnet with an internet gateway route
• c.Opening the security group to 0.0.0.0/0 on all ports
• d.Placing the databases in a private subnet with no internet gateway route✓

A private subnet has no route to an internet gateway, so its instances cannot be reached directly from the internet, which is appropriate for database tiers. Public IPs, public-subnet routing, or wide-open security groups would expose the databases.

During capacity planning for a new deployment, which metric pair is most relevant when choosing an appropriately sized compute instance?

• a.Data center latitude and longitude
• b.Expected vCPU and memory utilization✓
• c.The provider's stock ticker and market cap
• d.The color of the management console theme

Right-sizing an instance requires matching its vCPU and memory to the workload's expected utilization to avoid over-provisioning cost or under-provisioning performance. The other options have no bearing on instance sizing.
