Quiz tematico 1: Core data concepts

  1. Domanda 1 di 20

    Which kind of data follows a fixed schema, so every record has the same fields?
    Mostra la risposta

    Risposta: A. Structured data

    Structured data follows a fixed schema, usually as tables of rows and columns, so all records have the same fields.

  2. Domanda 2 di 20

    A company stores customers as JSON documents. Some customers have two email addresses, and some have none. What kind of data is this?
    Mostra la risposta

    Risposta: B. Semi-structured data

    Semi-structured data has some structure but allows variation between records. JSON is a common format for it.

  3. Domanda 3 di 20

    Video recordings from a security camera are an example of which kind of data?
    Mostra la risposta

    Risposta: B. Unstructured data

    Documents, images, audio, video and other binary files have no specific structure, so they are unstructured data.

  4. Domanda 4 di 20

    In a customer record, the customer's phone number is best described as what?
    Mostra la risposta

    Risposta: D. An attribute of an entity

    Entities are the things an organization cares about, such as customers. Attributes are their characteristics, such as name, address and phone number.

  5. Domanda 5 di 20

    Which file format separates fields with commas and puts each record on its own line?
    Mostra la risposta

    Risposta: D. CSV

    CSV is the most common delimited text format: commas separate fields, and a new line ends each row.

  6. Domanda 6 di 20

    Which human-readable format uses tags in angle brackets and has largely been replaced by the less wordy JSON format?
    Mostra la risposta

    Risposta: A. XML

    XML defines elements and attributes with tags in angle brackets. It was popular in the 1990s and 2000s, but JSON has largely replaced it.

  7. Domanda 7 di 20

    Which statement describes the Parquet file format?
    Mostra la risposta

    Risposta: A. A columnar format that stores each column's data together

    Parquet is a columnar format from Apache. Data for each column is stored together in row groups, and metadata helps apps find the right chunk quickly.

  8. Domanda 8 di 20

    Which optimized file format is row-based and stores a JSON header that describes the binary records in the file?
    Mostra la risposta

    Risposta: A. Avro

    Avro is a row-based format created by Apache. Its JSON header describes the structure, and the data is stored as binary blocks of records.

  9. Domanda 9 di 20

    In which type of non-relational database does each record have a unique key and a value that can be in any format?
    Mostra la risposta

    Risposta: A. Key-value database

    A key-value database stores each record as a unique key with an associated value in any format.

  10. Domanda 10 di 20

    A social network wants to store people as nodes and the links between them as relationships. Which type of database fits best?
    Mostra la risposta

    Risposta: B. Graph database

    Graph databases store entities as nodes, with links that define the relationships between them.

  11. Domanda 11 di 20

    Which type of database is a form of key-value database in which the value is a JSON document that the system can parse and query?
    Mostra la risposta

    Risposta: A. Document database

    A document database is a specific form of key-value database where the value is a JSON document the system is optimized to parse and query.

  12. Domanda 12 di 20

    A store's checkout system records thousands of sales every hour and must create, read, update and delete records quickly. What kind of workload is this?
    Mostra la risposta

    Risposta: B. A transactional (OLTP) workload

    Online transactional processing (OLTP) systems record many small transactions and are optimized for both reads and writes (CRUD operations).

  13. Domanda 13 di 20

    A bank moves $75 from account A ($500) to account B ($120). The debit from A works, but the credit to B fails. If the system follows ACID rules, what are the balances after the transaction ends?
    Mostra la risposta

    Risposta: A. A $500 and B $120

    Atomicity means a transaction succeeds completely or fails completely. Because the credit failed, the debit is also undone, so both balances stay as they were.

  14. Domanda 14 di 20

    A transaction is committed, and then the database server loses power. When the server restarts, the change is still there. Which ACID property is this?
    Mostra la risposta

    Risposta: D. Durability

    Durability means that once a transaction is committed, it stays committed, even if the system is switched off and on again.

  15. Domanda 15 di 20

    While a transfer between two accounts is in progress, another query cannot see one account before the transfer and the other after it. Which ACID property is this?
    Mostra la risposta

    Risposta: C. Isolation

    Isolation means transactions running at the same time cannot interfere with each other, so no query sees a half-finished transfer.

  16. Domanda 16 di 20

    Which role is mainly responsible for database availability, performance, backup and recovery plans, and granting users access to data?
    Mostra la risposta

    Risposta: A. Database administrator

    Database administrators manage the design, operation and security of databases, including backups, recovery and user permissions.

  17. Domanda 17 di 20

    Which role designs and builds data ingestion pipelines, cleansing and transformation steps, and data stores for analytical workloads?
    Mostra la risposta

    Risposta: A. Data engineer

    Data engineers build and monitor the pipelines that move and transform data, and they apply data cleaning routines across the organization.

  18. Domanda 18 di 20

    Which role explores data to find trends, builds analytical models and creates reports and visualizations for the business?
    Mostra la risposta

    Risposta: B. Data analyst

    Data analysts turn raw data into insights by exploring it, modelling it and presenting it in reports and visualizations.

  19. Domanda 19 di 20

    In an analytics solution, data is extracted and loaded into the data lake first, and transformed afterwards. What is this pattern called?
    Mostra la risposta

    Risposta: D. ELT

    In ELT (extract, load, transform), data is loaded first and transformed afterwards. In ETL, it is transformed before it is loaded.

  20. Domanda 20 di 20

    Which type of analytical store combines the flexible, scalable file storage of a data lake with the relational querying of a data warehouse?
    Mostra la risposta

    Risposta: B. A data lakehouse

    A data lakehouse puts table abstractions over files in a data lake, so you get lake storage with warehouse-style SQL querying.

Cosa sapere prima del test

  • The DP-900 skills measured (as of July 21, 2026) have four areas: core data concepts (25–30%), relational data on Azure (20–25%), non-relational data on Azure (15–20%) and an analytics workload (25–30%).
  • A passing score is 700 or greater. Scores are on a scale of 1 to 1,000, and because they are scaled, 700 may not equal 70% of the points.
  • Fundamentals exams have an exam time of 45 minutes, and Microsoft suggests allowing 65 minutes of seat time.
  • Microsoft does not list the exact number of DP-900 questions. It says most of its certification exams have 40–60 questions, but the number can vary.
  • There is no penalty for guessing, and some exam questions may be unscored, so answer every question.
  • The exam is proctored. You can schedule it through Pearson VUE, or through Certiport if you are a student or educator.
  • If you fail, you can retake the exam 24 hours after the first attempt; the wait for later retakes varies.
  • Fundamentals certifications do not expire.
