A company runs a containerized data processing application on a single VM. The application must be highly available, and the team wants to avoid managing the orchestration control plane. The company also has a budget constraint that favors paying only for the compute resources used. Which solution best balances all these requirements?

Keep the application on the single VM but add a manual failover script.

Move the application to a managed container orchestration service with autoscaling.

Deploy the application to multiple VMs and manage the orchestration manually.

Use a serverless function to replace the containerized application.

What is the primary purpose of containerization in modern data environments?

To package an application with its dependencies so it runs consistently across different environments

To provide a full operating system for each application

To replace virtual machines entirely in all scenarios

To store large amounts of unstructured data

A small business needs to store 2 TB of customer transaction data. The data is accessed by a single application running on a local server. The business wants a simple, low-cost solution with low latency. Which storage solution is most appropriate?

Use a cloud object storage bucket and access it over the internet.

Use a local direct-attached storage (DAS) device connected to the server.

Use a cloud block storage volume attached to a cloud VM.

Use a network-attached storage (NAS) device shared across the office network.

A research lab generates 10 TB of new data daily. The data must be immediately available for analysis and then retained for 10 years. The lab has a limited budget and wants to minimize storage costs while ensuring fast access to recent data. Which storage strategy is most cost-effective?

Store all data in a low-cost archive tier and accept slower access for all data.

Store all data on-premise on a single large NAS device.

Use a tiered storage approach: high-performance storage for recent data and a lower-cost archive tier for older data.

Store all data in a single high-performance storage tier for the entire 10-year period.
