Pass the Oracle Autonomous Database 1z0-931-25 Questions and answers with ExamsMirror

Restoring an Autonomous Database involves specific recovery options:

Correct Answer (A): “Selecting the backup from which restore needs to be done” allows you to choose a specific automatic backup (listed by timestamp) in the OCI Console to restore the database to that state.

Correct Answer (D): “Specifying the point in time (timestamp) to restore” enables Point-in-Time Recovery (PITR), restoring to any moment within the backup retention period (default 60 days), even between backups.

Incorrect Options:

B: There’s no “snapshot of the backup” option; backups are managed as full/incremental sets, not user-selectable snapshots.

Third-party software can connect to an Autonomous Database using standard Oracle connectivity options. The correct answer is:

Any protocol supported by Oracle Net Services (B):Autonomous Database leveragesOracle Net Services (also known as SQL*Net) for connectivity, supporting protocols like TCP/IP with TLS for secure communication. This allows a wide range of third-party tools (e.g., SQL Developer, Tableau, or custom applications) to connect using established Oracle networking standards.

The incorrect options are:

New ADB-specific protocols (A):There are no proprietary, ADB-specific protocols; it uses Oracle’s existing Net Services framework.

SQL*NET only (C):While SQLNet is part of Oracle Net Services, the broader term “Oracle Net Services” encompasses all supported protocols, not just SQLNet.

JDBC only (D):JDBC is a specific Java-based API for database connectivity, not a protocol, and it’s just one of many ways to connect via Oracle Net Services.

This flexibility ensures compatibility with diverse client applications.

When auto scaling is enabled in Oracle Autonomous Database, it dynamically adjusts resources to handle workload demands. The correct answer is:

Enables the database to use up to 3x CPU/IO resources immediately when needed by the workload (D):Auto scaling allows the database to automatically scale its CPU and I/O resources up to three times the base number of OCPUs provisioned, without manual intervention. This ensures the database can handle sudden spikes in demand efficiently, reverting to the base level when the workload decreases. This feature applies to both Autonomous Transaction Processing (ATP) and Autonomous Data Warehouse (ADW).

The incorrect options are:

Increases the number of sessions available to the database (A):Auto scaling does not directly increase session limits; session capacity is tied to the service level (e.g., LOW, MEDIUM, HIGH) and not dynamically adjusted by auto scaling.

Scales the PGA and SGA size when needed for the workload (B):The Program Global Area (PGA) and System Global Area (SGA) are memory structures managed automatically by Oracle, but auto scaling specifically adjusts CPU and I/O resources, not memory allocation directly.

Database concurrency is scaled up when needed by the workload (C):While increased CPU/IO resources can improve concurrency indirectly, auto scaling does not explicitly manage concurrency levels; this is more related to connection service settings.

This capability enhances performance elasticity for unpredictable workloads.

When creating an Autonomous Container Database (ACD) on dedicated infrastructure, Oracle offers specific patch types for maintenance. The correct answer is:

Release Update (RU) (D):During the creation of an ACD via the OCI console, users can choose to apply a Release Update (RU), which includes the latest security patches, bug fixes, and enhancements for the database version. RUs are the standard patching mechanism for Autonomous Databases on dedicated infrastructure, ensuring the system stays current.

The incorrect options are:

Quarterly Bundle Patch (QBP) (A):QBPs are not a recognized patch type for Autonomous Databases; they are more associated with on-premises Oracle deployments, not the cloud-native Autonomous infrastructure.

Prior Release Update Revision (PRUR) (B):PRURs are minor updates to prior releases,but they are not offered as a distinct option during ACD creation; Oracle focuses on RUs for consistency.

Prior Release Update (PRU) (C):PRUs refer to updates from previous major releases, but Autonomous Databases typically apply the latest RU, not prior ones, during provisioning or maintenance.

RUs align with Oracle’s strategy for maintaining Autonomous Databases.

Downloading Autonomous Database credentials (client wallet) is necessary for secure connections. The two correct actions are:

Find the service console for your Autonomous Database, then pick administration, then download the credential wallet (B):In the OCI console, navigate to the Autonomous Database service console (e.g., via the “Database” section). Select your ADB instance, go to the “Administration” tab, and click “Download Client Credentials (Wallet).” You’ll set a password and download a ZIP file containing files like tnsnames.ora and certificates. This method is straightforward for DBAs managing the instance directly from its service page.

Click on the Autonomous Database in the menu, click a database name, then choose DB Connection button, then download the wallet (D):From the OCI console’s main navigation, go to “Autonomous Database,” select your database by name, and click the “DB Connection” button on the details page. Then, select “Download Wallet,” provide a password, and download the ZIP file. This is a common path for users accessing connectivity details directly from the database overview.

The incorrect options are:

Click the compute section of the menu, then choose instance configurations, then download wallet (A):The “Compute” section is for virtual machines, not databases. Credentials are tied to the ADB service, not compute instances.

Click on the Object Storage and find your Autonomous bucket and download the wallet credentials (C):Object Storage holds user data or backups, not the wallet credentials, which are generated and downloaded from the ADB service interface.

Both B and D provide secure access to the wallet for tools like SQL Developer.

Keeping Autonomous Database tables synchronized with an on-premises data source involves loading and updating data from external locations. TheCloud Locations cardon the Data Loadpage is the correct method:

Correct Answer (B): The Cloud Locations card allows users to connect to Oracle Cloud Infrastructure (OCI) Object Storage buckets and load data into Autonomous Database tables. By regularly updating the data in Object Storage from the on-premises source (e.g., via scripts or tools), you can maintain synchronization using this feature. It supports automated data loading workflows when paired with appropriate processes.

Incorrect Options:

A: Oracle REST Data Services (ORDS) is used for building RESTful web services, not for direct data synchronization from on-premises sources to Autonomous Database tables.

C: The Link Data option enables linking to external database tables (e.g., via database links), but it doesn’t inherently synchronize data; it provides access rather than replication.

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.

Scaling OCPUs in an Autonomous Database triggers a specific status update. The correct answer is:

SCALING IN PROGRESS (D):When you increase (or decrease) the number of OCPUs,the database status in the OCI console changes to “SCALING IN PROGRESS.” This indicates that the system is actively adjusting the compute resources, a process that typically completes in a few minutes with no downtime for active transactions.

The incorrect options are:

UPSCALE IN PROGRESS (A):“Upscale” is not an official status term used by Oracle for this operation.

RESIZING IN PROGRESS (B):While “resizing” might intuitively fit, Oracle specifically uses “SCALING IN PROGRESS” for CPU adjustments.

UPLIFT IN PROGRESS (C):“Uplift” is not a recognized status in the context of Autonomous Database scaling.

This status reflects Oracle’s terminology for dynamic scaling.

The client credentials wallet for connecting to an Oracle Autonomous Database contains specific files required for secure connectivity. These files are downloaded from the OCI Console when you generate a wallet:

Correct Answer (A): protocol.ora is not a standard component of the client credentials wallet. It is typically used in traditional Oracle Database setups to define protocol parameters (e.g., TCP vs. IPC), but in Autonomous Database, such details are managed by Oracle and embedded within other wallet files like ewallet.p12.

Included Files:

B. ewallet.p12: Contains the encrypted private key and certificates for authentication.

C. sqlnet.ora: Specifies network configuration details (e.g., wallet location, encryption settings).

D. keystore.jks: A Java KeyStore file for Java-based applications to authenticate with the database.

Database Actions (formerly SQL Developer Web) offers tools for database management:

Correct Answer (A): TheCatalogtool provides a detailed view of database entities (tables, views, schemas) and their metadata, including dependencies via the “Impact” tab. It helps assess how changes (e.g., dropping a table) affect related objects.

Incorrect Options:

B: Data Load is for importing data, not analyzing entities or dependencies.

C: JSON is a data format, not a tool; it’s supported but irrelevant here.
