Which storage solution is most appropriate for storing infrequently accessed, long-term archival data that must be retained for regulatory compliance?

Solid-state drive (SSD) in a server

A government agency has a mandate that all data must be stored on infrastructure owned and operated by the agency itself. The agency is planning a new data lake. Which infrastructure choice complies with this mandate?

Deploy a data lake on servers in the agency's own data center.

Use a public cloud object storage service.

Use a hybrid cloud with the data lake on-premise and backups in the cloud.

Use a private cloud hosted by a government-approved vendor.

A data pipeline runs as a set of microservices. The team wants to deploy these services together with their dependencies in a way that is isolated from each other but shares the same host operating system kernel. Which technology best fits this requirement?

A single large VM running all services in the same process.

Containers managed by an orchestration platform.

Virtual machines with a hypervisor.

Bare-metal servers with each service on a separate physical machine.

Which of the following is a characteristic of on-premise data infrastructure?

Hardware is owned and maintained by the organization within its own facilities

Resources are provisioned over the internet by a third-party provider

Costs are primarily operational with no capital expenditure

Scaling is immediate and does not require procurement processes

A data platform team deploys a containerized application that must be highly available and automatically recover if a container fails. The team wants to minimize operational overhead for managing the orchestration control plane. Which deployment approach best meets these requirements?

Run the application as a serverless function instead of containers.

Use a managed container orchestration service that handles the control plane.

Deploy containers on a single VM and use a restart policy.

Manually manage a container orchestration cluster on self-managed VMs.
