A social media platform processes user posts to generate trending topics. The platform needs to update trending topics every few minutes, but it does not require second-by-second accuracy. The engineering team wants to balance near-real-time updates with lower infrastructure costs. Which ingestion approach is most suitable?

Full streaming ingestion with per-event processing

Micro-batch ingestion with processing every 2 minutes

A healthcare organization is required by regulators to demonstrate that patient data in its analytics platform originated from the authorized electronic health record (EHR) system and was not altered during ingestion. Which data governance practice should the organization implement to satisfy this requirement?

Implementing data lineage tracking for all patient data

Using a data masking tool to anonymize patient data

Increasing the frequency of data backups

Encrypting patient data in transit and at rest

A telecommunications company needs to process call detail records (CDRs) for billing. The billing system requires complete records for each call, and the company has a regulatory deadline to produce bills by the end of the month. The company also wants to provide customers with near-real-time usage alerts. Which ingestion strategy best balances these requirements?

Streaming ingestion for usage alerts and batch ingestion for billing

Micro-batch ingestion every 5 minutes for both use cases

Batch ingestion for both usage alerts and billing

Streaming ingestion for both usage alerts and billing

A data platform team is designing a pipeline that ingests data from multiple external vendors. Each vendor provides data in a different format and at different frequencies. The team must ensure that the pipeline can handle schema changes from vendors without breaking downstream consumers. Which pipeline design principle is most important?

Schema evolution support with versioned schemas

A data analyst is investigating a data quality issue in a nightly batch report. The analyst suspects that a transformation step incorrectly joined two tables, causing duplicate records.
