45. Frage
Which option describes the connection types that third-party software can use to connect to an Autonomous Database (ADB)?
Antwort: D
Begründung:
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 leverages Oracle 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.
46. Frage
What happens with the standby database when disabling Autonomous Data Guard?
Antwort: C
Begründung:
Disabling Autonomous Data Guard affects the standby database:
Correct Answer (A): “The standby database is terminated” is true. When Data Guard is disabled via the OCI Console or API, the standby database is deleted, ending its role as a replica. This is a permanent action requiring re-enablement to recreate a standby.
Incorrect Options:
B: The standby doesn’t become read-write; it’s removed entirely.
C: It doesn’t remain read-only; termination stops all operations.
D: It’s not converted to a refreshable clone; that’s a separate feature.
This ensures resource cleanup when high availability is no longer needed.
47. Frage
Which two options are available for restoring an Autonomous Database? (Choose two.)
Antwort: A,C
Begründung:
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.
C: “Archived custom image” is not a feature of Autonomous Database restore; it applies to other OCI services like Compute.
These options provide flexibility for recovery scenarios.
48. Frage
Which two statements apply to the Autonomous Database service on Dedicated Infrastructure? (Choose two.)
Antwort: A,B
Begründung:
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.
49. Frage
DBSRV1 is an Autonomous Database with the display name PRODDB. You plan to take manual backups of this database periodically. What must be the name of the bucket that will be used to store manual backups?
Antwort: C
Begründung:
Manual backups in Autonomous Database are stored in OCI Object Storage, and the bucket name follows a strict convention. The correct name is:
BACKUP_DBSRV1 (D): For manual backups, ADB uses a bucket named BACKUP_<DB_UNIQUE_NAME> (all uppercase). Here, DBSRV1 is the database’s unique name (not the display name PRODDB), so the bucket must be BACKUP_DBSRV1. This bucket is automatically created by Oracle when you initiate a manual backup via the OCI console (e.g., “Create Manual Backup” button) or API (e.g., oci db autonomous-database backup create). For example, backing up DBSRV1 on March 18, 2025, stores files like backup_DBSRV1_20250318.dmp in this bucket. The unique name ensures uniqueness across the tenancy, as display names (e.g., PRODDB) might not be unique but the DB_UNIQUE_NAME is system-assigned and distinct.
The incorrect options are:
backup_proddb (A): This uses the display name proddb and lowercase, violating the BACKUP_<UNIQUE_NAME> uppercase convention.
BACKUP_PRODDB (B): While uppercase, it uses the display name PRODDB, not the unique name DBSRV1, so it’s incorrect. Display names are for human readability, not system identification.
backup_dbsrv1 (C): This uses lowercase and lacks the exact BACKUP_ prefix format, failing Oracle’s naming rule.
The rigid naming ensures consistency and automation in ADB’s backup system.
