Temaquiz 1: Core data concepts

  1. Fråga 1 av 20

    Which kind of data follows a fixed schema, so every record has the same fields?
    Visa svar

    Svar: A. Structured data

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

  2. Fråga 2 av 20

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

    Svar: B. Semi-structured data

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

  3. Fråga 3 av 20

    Video recordings from a security camera are an example of which kind of data?
    Visa svar

    Svar: B. Unstructured data

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

  4. Fråga 4 av 20

    In a customer record, the customer's phone number is best described as what?
    Visa svar

    Svar: 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. Fråga 5 av 20

    Which file format separates fields with commas and puts each record on its own line?
    Visa svar

    Svar: D. CSV

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

  6. Fråga 6 av 20

    Which human-readable format uses tags in angle brackets and has largely been replaced by the less wordy JSON format?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

    Svar: 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. Fråga 7 av 20

    Which statement describes the Parquet file format?
    Visa svar

    Svar: 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. Fråga 8 av 20

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

    Svar: 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. Fråga 9 av 20

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

    Svar: A. Key-value database

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

  10. Fråga 10 av 20

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

    Svar: B. Graph database

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

  11. Fråga 11 av 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?
    Visa svar

    Svar: 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. Fråga 12 av 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?
    Visa svar

    Svar: 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. Fråga 13 av 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?
    Visa svar

    Svar: 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. Fråga 14 av 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?
    Visa svar

    Svar: D. Durability

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

  15. Fråga 15 av 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?
    Visa svar

    Svar: C. Isolation

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

  16. Fråga 16 av 20

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

    Svar: A. Database administrator

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

  17. Fråga 17 av 20

    Which role designs and builds data ingestion pipelines, cleansing and transformation steps, and data stores for analytical workloads?
    Visa svar

    Svar: 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. Fråga 18 av 20

    Which role explores data to find trends, builds analytical models and creates reports and visualizations for the business?
    Visa svar

    Svar: B. Data analyst

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

  19. Fråga 19 av 20

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

    Svar: D. ELT

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

  20. Fråga 20 av 20

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

    Svar: 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.

Bra att veta före provet

  • 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.

How long is the real DP-900 exam, and how many questions does it have?

Microsoft gives Fundamentals exams 45 minutes. It does not publish the exact number of DP-900 questions; it says most of its exams have 40–60 questions.

What score do I need to pass DP-900?

You need 700 or greater on a scale of 1 to 1,000. It is a scaled score, so it may not equal 70% of the questions.

Does the Azure Data Fundamentals certification expire?

No. Microsoft says Fundamentals certifications do not expire.

How long is the final assessment here?

It has 40 questions in 40 minutes, drawn at random from all four topics, so every attempt is different. You need 80% to pass.

Är intyget ackrediterat eller officiellt erkänt?

Nej. Det är ett privat kursintyg, bara för dina kunskaper. Det är inte erkänt, ackrediterat eller godkänt av någon myndighet, tillståndsmyndighet, tillsynsmyndighet eller utbildningsinstitution, och det ersätter inte någon licens, certifiering eller utbildning som krävs enligt lag.
