NEW QUESTION # 23
Which three are use cases for Graph Studio? (Choose three.)
Answer: B,C,D
Explanation:
Graph Studio in Autonomous Database supports graph-based analysis:
Correct Answer (C): Pattern matching identifies relationships (e.g., fraud rings) using graph queries like PGQL.
Correct Answer (D): Clustering groups related nodes (e.g., communities) using graph algorithms.
Correct Answer (B): Churn analysis leverages graph relationships to predict customer loss (e.g., via influence networks), though less emphasized than C and D, it’s a valid use case.
Incorrect Options:
A: Facial recognition is image-based, not graph-based.
E: 3-D modelling is a misinterpretation; it’s not a primary graph use case.
These align with Graph Studio’s strengths in relationship analysis.
NEW QUESTION # 24
Which two statements are true about using an Oracle Autonomous Database with private endpoints? (Choose two.)
Answer: B,C
Explanation:
Private endpoints enhance security for Autonomous Database:
Correct Answer (A): “A Network Security Group is required within your Virtual Cloud Network before you can provision a shared Autonomous Database to use private endpoints” is true. An NSG is mandatory to define ingress/egress rules for the private subnet hosting the endpoint.
Correct Answer (C): “Private endpoints can be configured when you clone a shared Autonomous Database that was initially created with public endpoints” is true. Cloning allows switching to a private endpoint configuration.
Incorrect Options:
B: Private endpoints are inaccessible from the public internet, even with ACLs; that’s their purpose.
D: Always Free tier doesn’t support private endpoints; it’s limited to public access.
This ensures isolated, secure connectivity.
NEW QUESTION # 25
Which statement is true when you provision an Autonomous Database using the cloning method?
Answer: C
Explanation:
Cloning in Autonomous Database creates a new instance from an existing source:
Correct Answer (A): “A clone database source can be a running database instance” is true. You can clone from a live, running Autonomous Database instance (full clone), capturing its current state, including data and configuration, without needing to stop it.
Incorrect Options:
B: There are multiple cloning types: full clone (from a running instance) and refreshable clone (a read-only copy that syncs with the source), plus cloning from backups.
C: Cloning from a backup requires the backup to be at least 2 hours old for consistency, not less, making this false.
D: Security zone rules prevent cloning a database from a security zone to a non-security zone due to compliance restrictions.
This flexibility supports rapid provisioning from active databases.
NEW QUESTION # 26
You created an Autonomous Database without auto scaling. Which two ways can you enable auto scaling? (Choose two.)
Answer: B,D
Explanation:
Enabling auto scaling on an existing Autonomous Database can be done without unnecessary complexity:
Correct Answer (A): “Click Scale Up/Down and select the Auto Scaling checkbox” is the simplest GUI method. In the OCI Console, navigate to the database, select “Scale Up/Down,” and enable the auto scaling option, allowing up to 3x the base OCPUs dynamically.
Correct Answer (C): “Use a REST call to enable Auto Scaling” leverages the OCI REST API to update the database configuration with the isAutoScalingEnabled parameter set to true. This is ideal for programmatic control.
Incorrect Options:
B: Shutting down the instance is unnecessary; auto scaling can be enabled while the database is running.
D: Multiple REST calls, including shutdown and restart, overcomplicate the process when a single API call suffices.
These methods ensure minimal disruption and efficient resource management.
NEW QUESTION # 27
A Business Analyst joined your organization and wants to explore the database tools. When restoring or cloning an Autonomous Database (ADB), you must select a backup that is at least how old?
Answer: C
Explanation:
Full Detailed In-Depth Explanation:
When restoring or cloning an Autonomous Database (ADB), Oracle enforces a minimum backup age to ensure data consistency and integrity. The official Oracle documentation specifies that backups used for these operations must be at least 24 hours old. This requirement exists because:
Backups need time to complete and stabilize, ensuring all transactions are fully committed and the backup is consistent.
Recent backups (e.g., less than 24 hours old) may still be in progress or lack full verification, risking incomplete or corrupted restores/clones.
Options B (5 minutes), C (2 hours), and D (1 day) are either too short or redundant:
5 minutes and 2 hours: Too recent, violating the 24-hour rule.
1 day: Matches 24 hours but is less precise than the explicit “24 hours” phrasing in the documentation.
For the Business Analyst’s exploration, they can access tools like SQL Developer Web or Data Load via the OCI Console under the “Tools” tab, but this question focuses on the backup age constraint, making A the best answer.
