NEW QUESTION # 142
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?
Answer: C
Explanation:
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.
NEW QUESTION # 143
Oracle Autonomous Database on Dedicated Infrastructure is composed of which Oracle Cloud resources?
Answer: B
Explanation:
Full Detailed In-Depth Explanation:
Autonomous Database on Dedicated Infrastructure comprises:
Autonomous Exadata Infrastructure: The hardware and software foundation.
Autonomous Container Database: Hosts multiple ADB instances.
Autonomous Database: The managed database instance.
Autonomous Backup: Automatic backups to OCI Object Storage.
Other options include roles (B, C) or general OCI resources (D), not core components of the service. A is the correct composition.
NEW QUESTION # 144
Which of the following two statements regarding Data Transforms are correct? (Choose two.)
Answer: B,D
Explanation:
Data Transforms is a feature in Autonomous Database for designing data transformations. The two correct statements are:
Data Transforms allows you to design data transformations in the form of data loads, data flows, and workflows (B): True. Data Transforms provides a graphical interface to create data loads (importing data), data flows (transforming data), and workflows (sequencing operations), simplifying ETL processes within ADB.
All capabilities to transform data in ODI Classic are available with ODI Web Edition (D): True. Oracle Data Integrator (ODI) Web Edition, which integrates with Data Transforms, retains the full transformation capabilities of ODI Classic, adapted for a web-based interface.
The incorrect statements are:
Data Transforms provides access to Oracle Data Integrator (ODI) Web Edition (A): False. Data Transforms is a distinct tool within ADB; while it leverages ODI under the hood, it does not directly provide access to ODI Web Edition as a standalone product.
Workflows for Data Transforms are only available on the ODI Web Edition (C): False. Workflows are part of Data Transforms itself, not exclusive to ODI Web Edition.
These features enhance data integration in ADB.
NEW QUESTION # 145
Who, and in which order, provisions dedicated Exadata Infrastructure resources?
Answer: B
Explanation:
Provisioning dedicated Exadata Infrastructure resources for Autonomous Database follows a strict hierarchical order, reflecting roles and dependencies. The correct sequence is:
The Fleet Administrator provisions the Autonomous Exadata Infrastructure and then the Autonomous Container DB and then, the Database Administrator provisions the Autonomous DB (A):
Fleet Administrator provisions Autonomous Exadata Infrastructure (AEI): The Fleet Admin, responsible for infrastructure management, starts by provisioning the AEI via the OCI console (e.g., "Create Autonomous Exadata Infrastructure"). This sets up the physical Exadata hardware, networking (e.g., VCN, subnets), and initial configuration (e.g., 2 racks, 4 nodes). For example, they might specify a compartment and region (e.g., us-ashburn-1), taking 1-2 hours for provisioning.
Fleet Administrator provisions Autonomous Container DB (ACD): Within the AEI, the Fleet Admin creates the ACD (e.g., "Create Autonomous Container Database"), a lightweight container hosting multiple ADBs. They set parameters like version (e.g., 19c) and maintenance windows (e.g., Sundays 02:00 UTC), ensuring the container is ready. This step might take 15-30 minutes.
Database Administrator provisions Autonomous DB (ADB): Finally, the DBA provisions individual ADBs within the ACD (e.g., "Create Autonomous Database"), choosing workload type (ATP/ADW), OCPUs (e.g., 4), and storage (e.g., 1 TB). For instance, they might create an ATP instance named PRODDB for a transactional app, completing setup in 5-10 minutes.
The incorrect options are:
B: The DBA can't provision the ACD or ADB before the AEI exists, as the infrastructure is foundational. The Fleet Admin must act first.
C: The DBA doesn't provision AEI-that's an infrastructure task beyond their scope. The Fleet Admin handles hardware setup.
D: The DBA can't provision the ACD; that's a Fleet Admin task within the AEI. Roles are distinct: Fleet Admin for infra, DBA for databases.
This order ensures proper infrastructure setup before database creation, aligning with OCI's role-based workflow.
NEW QUESTION # 146
Which management operation is correct about Autonomous Databases on Shared Exadata Infrastructure?
Answer: B
Explanation:
Management operations for Autonomous Databases on Shared Exadata Infrastructure are limited due to its fully managed nature. The correct statement is:
You cannot configure the scheduling for your Autonomous Databases on Shared Exadata Infrastructure (C): In shared infrastructure, Oracle fully controls maintenance scheduling (e.g., patching, upgrades). Unlike dedicated infrastructure, where users can set maintenance windows, shared ADB users cannot adjust timing. Oracle notifies users of upcoming maintenance (e.g., via email or console), typically in a 7-day window, but the exact schedule is Oracle-driven to optimize the shared Exadata platform. For example, a quarterly patch might occur on a Tuesday at 2 AM UTC, and users must adapt, not reschedule.
The incorrect options are:
You can skip a scheduled maintenance run... (A): False. Shared infrastructure does not allow skipping maintenance runs, even for two quarters. This flexibility exists only in dedicated infrastructure, where users have more control (e.g., skipping up to two consecutive updates). In shared mode, Oracle enforces updates for security and stability across all tenants.
You can perform a "rolling restart"... (B): False. Rolling restarts (restarting nodes sequentially for availability) are not user-initiated in ADB shared infrastructure. Restarts, if needed, are managed by Oracle during maintenance, and users cannot control the process or ensure node-by-node availability.
You can choose to use Release Update or Release Update Revision updates... (D): False. In shared infrastructure, Oracle applies Release Updates (RUs) uniformly across all databases; users cannot choose between RU or Release Update Revisions (RURs), a feature reserved for dedicated deployments.
This reflects the trade-off of shared infrastructure: lower cost and management effort for less control.
