CTO Data Strategy & Analytics 5

Question 1

A CTO must present the ROI of a proposed data platform investment to the board. Which framework is most appropriate?

Accepted Answer

Value driver mapping linking data capabilities to revenue, cost, risk, and agility outcomes

Answer

Boards respond to business value framing; mapping data capabilities to specific drivers like revenue growth, cost reduction, and risk mitigation demonstrates strategic ROI.

Question 2

In a multi-cloud data strategy, what is the primary risk a CTO must plan for?

Accepted Answer

Excessive redundancy causing data inconsistency across clouds

Answer

Multi-cloud deployments risk data fragmentation and synchronization inconsistencies when the same datasets exist across providers without a coherent replication strategy.

Question 3

Which data anonymization technique replaces a sensitive identifier with a consistent token, preserving referential integrity across datasets?

Accepted Answer

Tokenization

Answer

Tokenization substitutes a sensitive value with a non-sensitive token that remains consistent, allowing joins across datasets without exposing the original identifier.

Question 4

A CTO is establishing a 'golden record' strategy for customer data. What problem does this solve?

Accepted Answer

Duplicate and conflicting customer records across multiple source systems

Answer

A golden record (master data management) creates a single authoritative customer profile by deduplicating and reconciling data from multiple source systems.

Question 5

When building a real-time analytics pipeline, which architecture pattern provides the lowest latency for updating business dashboards?

Accepted Answer

Event streaming with Apache Kafka and stream processing (e.g., Flink or Spark Streaming)

Answer

Event streaming with Kafka and a stream processor delivers sub-second latency by processing events continuously as they are produced rather than in batches.
