CompTIA Data+ Exam DA0-002 Prüfungsfragen mit Lösungen (Q78-Q83):

78. Frage
A company gives users adequate data access permissions to allow them to fulfill their duties but nothing more. Which of the following concepts best describes this practice?

Antwort: C

Begründung:
The principle of least privilege grants users only the minimum access rights necessary to perform their job responsibilities. This reduces security risks by limiting access to data and systems that are not required for their duties.


79. Frage
Which of the following is the best language to use in a notebook?

Antwort: A


80. Frage
A data analyst is working on a three-year project to deliver sales reports on a monthly basis. The client wants a thorough analysis into customer profiles for a specific region and month. Which of the following delivery methods best fulfills this request?

Antwort: D

Begründung:
An ad hoc delivery method is used when a stakeholder requests a detailed, specific analysis that is not part of the standard recurring reports. The request for a thorough analysis of customer profiles for a particular region and month is a targeted, one-time inquiry that is best fulfilled through an ad hoc report.


81. Frage
Which of the following is found in metadata?

Antwort: B

Begründung:
Data lineage describes the origin, movement, and transformation history of data, which is a key component of metadata used to understand how data is created and used.


82. Frage
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).

Antwort: A,E

Begründung:
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.
