NEW QUESTION # 103
Which of the following is not required for connecting to Autonomous Database (ADB) via SQL Developer?
Answer: A
Explanation:
Connecting to Autonomous Database (ADB) via SQL Developer requires specific parameters. The correct answer is:
Connection Name (E): The Connection Name is a user-defined label in SQL Developer to identify the connection in the tool’s interface. It is not a technical requirement for establishing the database connection itself, making it optional in terms of connectivity.
The required parameters are:
Password (A): Essential for user authentication alongside the username.
Service (B): Refers to the service name (e.g., high, medium, low) from the wallet’s tnsnames.ora, specifying the performance level and connection type.
Username (C): Required to identify the database user.
Database name (D): Needed to specify the target database or PDB within the ADB instance, typically provided via the wallet configuration.
Without A, B, C, and D, the connection cannot be established, but E is merely a convenience.
NEW QUESTION # 104
While provisioning a dedicated Autonomous Container Database, which backup retention period CANNOT be implemented?
Answer: A
Explanation:
Full Detailed In-Depth Explanation:
When provisioning an Autonomous Container Database (ACD) on dedicated infrastructure, Oracle provides specific options for backup retention periods to balance data recovery needs with storage costs. According to the official Oracle documentation, the available backup retention periods for a dedicated ACD are:
7 days: This is the default retention period for a newly provisioned ACD.
15 days: An option for extended retention beyond the default.
60 days: The maximum supported retention period for ACDs, offering the longest recovery window.
The option of 120 days is not supported as a backup retention period for an Autonomous Container Database. This limitation is due to the design of the Autonomous Database service, which caps retention at 60 days to optimize storage and performance on dedicated Exadata infrastructure. Attempting to set a retention period beyond 60 days is not an available choice during provisioning. Users must select a retention period that meets their recovery point objectives (RPO) within these constraints, noting that longer retention increases storage usage and associated costs.
NEW QUESTION # 105
Which statement is FALSE about the Catalog tool?
Answer: B
Explanation:
The Catalog tool in Autonomous Database provides metadata exploration:
Correct Answer (A): “You can delete an entity from the Autonomous Database via the Catalog tool” is false. The Catalog is a read-only interface for viewing database objects (tables, views, etc.) and their relationships; it does not support modification or deletion actions.
True Statements:
B: Filtering by name, schema, type, or application is a core search feature.
C: Viewing DDL (data definition language) for entities is supported.
D: The Impact tab shows dependencies, aiding change analysis.
This ensures safe metadata exploration without risking data changes.
NEW QUESTION # 106
While creating an Autonomous Container Database on dedicated infrastructure through the Oracle Cloud Infrastructure (OCI) console, which patch type is offered to be applied during maintenance?
Answer: D
Explanation:
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.
NEW QUESTION # 107
Which two statements apply to the Autonomous Database service on Dedicated Infrastructure? (Choose two.)
Answer: C,D
Explanation:
Autonomous Database on Dedicated Infrastructure offers more control than shared infrastructure. The two correct statements are:
You, as the customer, are responsible for all patching operations (A): In dedicated infrastructure, customers manage patching for Autonomous Container Databases (ACDs) and Autonomous Databases (ADBs), unlike shared infrastructure where Oracle handles it. You choose when to apply Release Updates (RUs) or skip them (up to two quarters), using the OCI console or API (e.g., oci db autonomous-container-database update). For example, you might schedule an RU for an ACD on a Saturday night, downloading the patch from Oracle and applying it manually to minimize downtime. This responsibility comes with the dedicated model’s flexibility.
You can set maintenance windows for each individual Autonomous Container Database (C): Dedicated infrastructure allows setting specific maintenance windows per ACD, not just at the Exadata Infrastructure level. In the OCI console, under each ACD’s details, you configure a preferred time (e.g., “Sundays, 02:00-04:00 UTC”), ensuring patches or upgrades align with your schedule. For instance, ACD1 might patch Sundays, while ACD2 patches Tuesdays, tailoring downtime to different workloads.
The incorrect options are:
You can set maintenance windows for an Autonomous Exadata Infrastructure (B): Maintenance windows are set at the ACD level, not the broader Autonomous Exadata Infrastructure (AEI) level. AEI maintenance (e.g., hardware updates) is Oracle-managed, with notification but no customer scheduling.
Patching occurs on the first Sunday of each quarter (D): There’s no fixed schedule like “first Sunday.” In dedicated mode, you control patching timing within a quarter, notified by Oracle of available RUs, unlike shared infrastructure’s Oracle-driven schedule.
These statements highlight dedicated infrastructure’s customer-driven management.
