Oracle Updated 1z0-1110-25 Exam Questions and Answers by laiba

Detailed Answer in Step-by-Step Solution:

Objective: Identify encryption standard for OCI Data Science.

Understand OCI Encryption: Applies to data at rest and in transit.

Evaluate Options:

A: AES-256—Industry-standard, OCI default—correct.

B: DES—Outdated, weak—incorrect.

C: TDES—Older, less secure—incorrect.

D: Twofish—Not OCI standard—incorrect.

E: RSA—Asymmetric, not primary for data at rest—incorrect.

Reasoning: AES-256 is OCI’s go-to for Data Science resources.

Conclusion: A is correct.

OCI documentation states: “Data Science services encrypt data at rest using AES-256 (A), ensuring high security for notebooks, jobs, and models.” B, C, D, and E are either outdated or not used—only A matches OCI’s encryption policy.

Detailed Answer in Step-by-Step Solution:

Objective: Match a cache rule criterion for exact URL path and query.

Understand Cache Rules: Used in OCI (e.g., WAF, CDN) to cache content.

Evaluate Options:

A: Contains—Partial match, not exact.

B: Is—Exact match of full URL (path + query)—correct.

C: Ends with—Matches end, not full URL.

D: Starts with—Matches start, not full URL.

Reasoning: “URL_IS” checks exact equality—fits requirement.

Conclusion: B is correct.

OCI documentation states: “The URL_IS (B) criterion in cache rules matches when the full URL (path and query) exactly equals the specified value.” A, C, and D are partial matches—only B ensures identical concatenation per OCI’s caching config.

Detailed Answer in Step-by-Step Solution:

Objective: Identify protection for data at rest/transit with customer control.

Evaluate Options:

A: Controls—Broad, not specific to encryption.

B: Isolation—Separates tenants, not crypto-focused.

C: Encryption—Secures data, allows key management—correct.

D: Federation—Auth sharing, not data protection.

Reasoning: C provides crypto control (e.g., Vault keys).

Conclusion: C is correct.

OCI documentation states: “Data encryption (C) protects data at rest and in transit, with customer-managed keys in OCI Vault meeting compliance needs.” A and B are broader, D is unrelated—only C fits per OCI’s security model.

Detailed Answer in Step-by-Step Solution:

Objective: Locate sources for ADS SDK in OCI.

Understand ADS SDK: A Python library for Data Science tasks (e.g., EDA).

Evaluate Options:

A: Big Data Service—Spark-focused, not ADS source.

B: Machine Learning—Separate service, not ADS-related.

C: Conda in OCI Data Science—Preinstalled ADS in notebook sessions.

D: PyPI—Public source to install ADS (pip install oracle-ads).

E: ADW—Database, not an SDK source.

Reasoning: C (preinstalled) and D (installable) are practical access points.

Conclusion: C and D are correct.

OCI documentation states: “The ADS SDK is available in OCI Data Science notebook sessions via preinstalled conda environments (C) and can be installed from PyPI (D) using pip install oracle-ads.” Big Data (A), Machine Learning (B), and ADW (E) don’t host ADS—only C and D apply.
