NEW QUESTION # 138
Which of the following best describes the storage type that provides a unique identifier and metadata information?
Answer: A
Explanation:
Object storage stores data as objects, with each object containing the data itself, a unique identifier, and metadata that describes the object. This structure makes object storage highly scalable and well suited for managing large amounts of unstructured data.
NEW QUESTION # 139
A database administrator is investigating the reason a reporting job failed. The target-layer schema remained unchanged from the last run, and the database server is scalable. All of the users have default execute privileges on the report. Which of the following attribute changes most likely caused this incident?
Answer: D
Explanation:
A reporting job that previously ran successfully can fail when the volume of data increases beyond expected limits, causing timeouts, memory constraints, storage issues, or processing bottlenecks. Since the schema was unchanged, the server is scalable, and user permissions remained available, a change in data volume is the most likely cause of the failure.
NEW QUESTION # 140
A data analyst is creating a new dataset that involves bringing together the following datasets:
Name
ID
Date of birth
Frank
23525
3/19
Martha
11290
6/13
Ellen
12141
11/4
ID
Address
City
State
23525
1234 Harding
Chicago
IL
11040
935 Terrace Hills
Chino
CA
11290
2 Speedway
Miami
FL
Which of the following would be the output if the data analyst does a FULL JOIN?
Answer: D
Explanation:
This question falls under theData Concepts and Environmentsdomain, focusing on database operations like joins. A FULL JOIN combines all rows from both tables, including matches and non-matches, filling in NULLs where there's no corresponding data.
* The first table has IDs: 23525 (Frank), 11290 (Martha), 12141 (Ellen).
* The second table has IDs: 23525, 11040, 11290.
* A FULL JOIN includes all IDs: 23525, 11290, 12141, 11040.
* 23525 matches (Frank with 1234 Harding, Chicago, IL).
* 11290 matches (Martha with 2 Speedway, Miami, FL).
* 12141 has no match in the second table, so Address, City, and State are NULL.
* 11040 has no match in the first table, so Name and Date of birth are NULL.
* Option A: Incorrect; it includes a row for Ellen with "2 Speedway," but Ellen's ID (12141) doesn't match any address, and 11040 is missing.
* Option B: Identical to Option A, so incorrect for the same reasons.
* Option C: Incorrect; it mismatches addresses (e.g., Ellen with 935 Terrace Hills, which belongs to
11040).
* Option D: Correct; it includes all IDs, with NULLs for non-matching rows (Ellen has no address, and
11040 has no name).
The DA0-002 Data Concepts and Environments domain includes understanding "data schemas and dimensions," such as performing joins in relational databases.

NEW QUESTION # 141
Which of the following best describes an assessment a data analyst would use to validate that the number of records in a dataset matches the expected results?
Answer: B
Explanation:
This question pertains to theData Governancedomain, focusing on data quality validation techniques. The task is to validate that the number of records matches expectations, which requires a specific type of assessment.
* Source control (Option A): Source control (e.g., Git) manages code versions, not dataset validation.
* Unit test (Option B): A unit test checks a specific component of a process, such as verifying that the number of records in a dataset matches the expected count, making it the best fit.
* Stress test (Option C): Stress tests evaluate system performance under load, not record counts.
* Health check (Option D): A health check monitors system status but isn't specific to validating record counts.
The DA0-002 Data Governance domain includes "data quality control concepts," and unit tests are a standard method for validating specific data outcomes like record counts.

NEW QUESTION # 142
A database administrator needs to implement security triggers for an organization's user information database.
Which of the following data classifications is the administrator most likely using? (Select two).
Answer: C,E
Explanation:
This question pertains to theData Governancedomain, focusing on data classification for security purposes.
User information databases typically contain personal data, and security triggers (e.g., alerts for unauthorized access) require classifying data to determine protection levels.
* Public (Option A): Public data is openly accessible (e.g., company brochures), not suitable for user information requiring security triggers.
* Open (Option B): Open isn't a standard data classification; it's similar to public and not applicable here.
* Sensitive (Option C): Sensitive data includes information that, if exposed, could cause harm (e.g., user emails, roles), which fits user information and warrants security triggers.
* Non-Sensitive (Option D): Non-sensitive data doesn't require protection, so it wouldn't need security triggers.
* Private (Option E): Private data includes PII (e.g., names, addresses) in user information databases, requiring security measures like triggers to protect against breaches.
* Encrypted (Option F): Encrypted refers to a data state, not a classification; data can be classified as private or sensitive and then encrypted.
The DA0-002 Data Governance domain includes "data quality control concepts," such as classifying data to apply appropriate security measures. Sensitive and private classifications are most relevant for user information.
