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

Detailed Answer in Step-by-Step Solution:

Objective: Scale up a notebook session without losing work.

Understand Persistence: Block volume stores session data (e.g., /home/datascience).

Evaluate Options:

A: Recreating work—inefficient, risks loss.

B: Local download/upload—cumbersome, unnecessary.

C: Use block volume persistence, scale up—efficient, preserves work—correct.

D: Object Storage—extra steps, not needed with block volume.

Reasoning: C leverages OCI’s built-in persistence for seamless scaling.

Conclusion: C is correct.

OCI documentation states: “Files in /home/datascience are stored on the block volume. To scale up, deactivate the session, provision a new one with a larger shape, and the block volume persists your work.” A loses data, B and D add complexity—only C is optimal.

Detailed Answer in Step-by-Step Solution:

Objective: Classify a PagerDuty notification in OCI Monitoring.

Understand OCI Monitoring: Involves events, rules, and actions for notifications.

Evaluate Options:

A: Action—executes a response (e.g., notify PagerDuty) when triggered—correct.

B: Rule—defines conditions for triggering actions—precedes the action.

C: Function—serverless code, not directly tied to notifications.

D: Event—state change triggering a rule, not the notification itself.

Reasoning: The notification is the action taken after an event/rule—fits A.

Conclusion: A is correct.

OCI documentation states: “Actions in the Monitoring service execute responses, such as sending notifications to PagerDuty, when a rule’s condition is met based on an event.” Rules (B) set conditions, Functions (C) are unrelated, and Events (D) are triggers—only Action (A) describes the notification step.

Detailed Answer in Step-by-Step Solution:

Objective: Determine collaboration method in OCI Data Science (Notebook Sessions).

Evaluate Options:

A: Access control—Possible but not primary collaboration.

B: Version control (e.g., Git)—Standard for code sharing—correct.

C: Shared instance—Not supported; sessions are single-user.

D: Chat/video—Not a feature of OCI Data Science.

Reasoning: B leverages Git for team collaboration—OCI’s recommended method.

Conclusion: B is correct.

OCI documentation states: “Collaborate in Data Science by integrating version control systems like Git (B) with notebook sessions to share code and notebooks.” A is limited, C isn’t feasible, and D isn’t available—only B matches OCI’s collaboration approach.

Detailed Answer in Step-by-Step Solution:

Objective: Identify two methods to enhance Object Storage durability.

Understand Durability: Ensures data isn’t lost—focus on redundancy and protection.

Evaluate Options:

A: RAID1—Block volume feature, not Object Storage.

B: Encryption—Secures data, not durability.

C: Versioning—Retains old versions, prevents loss—correct.

D: Limit delete—Prevents accidental deletion—correct.

E: Client encryption—Secures, not durability-focused.

Reasoning: C and D directly protect against data loss—durability-focused.

Conclusion: C and D are correct.

OCI documentation states: “Improve Object Storage durability with Versioning (C) to retain previous object versions and by limiting delete permissions (D) to prevent accidental loss.” A isn’t applicable, B and E focus on security—only C and D enhance durability per OCI’s storage features.
