1. 1Which description best defines digital transformation in an organization?

   1. A. Replacing hardware while preserving every business process
   2. B. Using digital technology to change processes and customer experiences
   3. C. Converting paper records to images without changing their use
   4. D. Purchasing software licenses without changing how people work

   Answer: B

   Explanation: "Digital transformation uses modern digital technologies—including all types of public, private, and hybrid cloud platforms—to create or modify business processes, culture, and customer experiences to meet changing business and market dynamics." Transformation changes how the organization operates and delivers value; a technology purchase or format change alone does not establish that change.

2. 2A business wants consolidated historical data for recurring enterprise reporting. Which repository is designed for that purpose?

   1. A. An operational transaction database
   2. B. A raw-data lake
   3. C. An enterprise data warehouse
   4. D. An in-memory session cache

   Answer: C

   Explanation: "A data warehouse can store both current and historical data in one place and is designed to give a long-range view of data over time" A warehouse is designed for integrated current and historical enterprise reporting, rather than transactional or session processing and raw-data retention.

3. 3Which description best defines the field of artificial intelligence?

   1. A. A process for storing and retrieving records by exact keys
   2. B. A field enabling systems to perform human-like cognitive tasks
   3. C. A presentation layer that displays predefined business metrics
   4. D. An automation method limited to executing manually listed rules

   Answer: B

   Explanation: "AI is the broader concept of enabling a machine or system to sense, reason, act, or adapt like a human" AI encompasses cognitive abilities such as sensing and reasoning, rather than storage, reporting, or fixed rules alone.

4. 4A migration assessment concludes an application should remain in its current environment without changes. Which strategy is this?

   1. A. Rehost
   2. B. Retain
   3. C. Replatform
   4. D. Refactor

   Answer: B

   Explanation: "Retain—Keep the application as is, i.e. host it in the current environment" Retain keeps the application where it is; the other strategies involve moving or changing it.

5. 5Which security objective concerns protecting information from unauthorized disclosure?

   1. A. Confidentiality
   2. B. Integrity
   3. C. Availability
   4. D. Authentication

   Answer: A

   Explanation: "you need to ensure your organization’s data is kept private." Confidentiality protects privacy. Integrity concerns tampering, availability concerns access when needed, and authentication verifies identity.

6. 6Which spending change commonly accompanies moving from owned infrastructure to consumption-based cloud services?

   1. A. From operating expenses toward capital purchases of owned servers
   2. B. From capital purchases toward operating expenditures for consumed services
   3. C. From capital purchases to depreciation of newly owned cloud-provider hardware
   4. D. From operating expenses to capitalized ownership of each consumed service

   Answer: B

   Explanation: "the initial shift from an on-premises capital expenditures (CapEx) model to cloud-based operational expenditures (OpEx)." The cited transition is CapEx-owned infrastructure to cloud OpEx consumption, not acquisition/depreciation of provider hardware or capitalized service ownership.

7. 7Which description best defines the cloud computing delivery model?

   1. A. Owning servers installed in a company's office
   2. B. Buying software for installation on each employee's computer
   3. C. Accessing computing resources on demand as internet-delivered services
   4. D. Connecting company offices through a privately owned cable

   Answer: C

   Explanation: "Cloud computing is the on-demand availability of computing resources (such as storage and infrastructure), as services over the internet." The defining features are on-demand computing resources delivered as services, rather than ownership or connectivity alone.

8. 8Which repository is suited to retaining diverse raw datasets in their native formats for future analysis?

   1. A. A data lake
   2. B. A curated analytical data warehouse
   3. C. An operational relational database
   4. D. An in-memory application session store

   Answer: A

   Explanation: "A data lake is a centralized, scalable, and secure repository designed to store, process, and analyze large amounts of structured, semistructured, and unstructured data in its native format." A lake retains diverse data in native formats; the alternatives have different primary data-management purposes.

9. 9How does machine learning differ from explicitly programming a rule for every outcome?

   1. A. It requires people to supply every future answer manually
   2. B. It stores training examples without deriving a model
   3. C. It learns patterns from data to support predictions or decisions
   4. D. It executes a fixed lookup table without learning from examples

   Answer: C

   Explanation: "Instead of explicit programming, machine learning uses algorithms to analyze large amounts of data, learn from the insights, and then make informed decisions." ML learns from data rather than requiring an exhaustive set of manually specified outcome rules.

10. 10An unused legacy application is being decommissioned instead of migrated. Which strategy applies?

    1. A. Retain
    2. B. Rehost
    3. C. Retire
    4. D. Replatform

    Answer: C

    Explanation: "Retire—Decommission the application and compute at source" Retire removes the application and its source compute rather than preserving or moving it.
