NEW QUESTION # 85
What is the correct way to list all files in the default data pump directory?
Answer: C
Explanation:
In Oracle Autonomous Database, the DBMS_CLOUD package provides tools to interact with cloud storage and directory operations, including listing files in the default Data Pump directory (DATA_PUMP_DIR).
Correct Answer (A): The statement SELECT * FROM DBMS_CLOUD.LIST_FILES('DATA_PUMP_DIR'); is the officially supported method to list files in the DATA_PUMP_DIR. This function returns a result set with details about files in the specified directory, tailored for the managed environment of Autonomous Database.
Incorrect Options:
B: This is false; you can list files in DATA_PUMP_DIR using DBMS_CLOUD.LIST_FILES, as it is designed for this purpose in ADW.
C: The UTL_FILE package is not recommended for Autonomous Database due to its limitations in a cloud-managed environment. DBMS_CLOUD is the preferred utility for such operations. Additionally, the syntax UTL_FILE.LIST is incorrect; the proper procedure would be UTL_FILE.FGETATTR or similar, but it’s still not applicable here.
D: Autonomous Database is a fully managed service, and users do not have direct command-line access to the underlying server. Commands like ls -al are unavailable as there’s no shell access.
This approach ensures secure and efficient file management within the constraints of a serverless cloud database.
NEW QUESTION # 86
What are two differentiators of Oracle Autonomous Database on Dedicated Infrastructure? (Choose two.)
Answer: C,E
Explanation:
Autonomous Database on Dedicated Infrastructure offers unique features:
Correct Answer (A): “Users are offered greater control and isolation starting at the Exadata Cloud Infrastructure level” highlights dedicated hardware (compute, storage, network), ensuring isolation and performance not available in shared setups.
Correct Answer (E): “Users have more control over the maintenance schedule” allows scheduling maintenance windows, unlike shared infrastructure’s fixed schedules.
Incorrect Options:
B: OS customization is not allowed; Oracle manages the stack fully.
C: No OS access is provided; it’s a managed service.
D: SYS privileges are not unique to dedicated infrastructure; they depend on user roles, not deployment type.
These differentiators enhance control and isolation for enterprise needs.
NEW QUESTION # 87
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: B
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.
NEW QUESTION # 88
Which two statements are true about the Oracle Cloud Infrastructure (OCI)? (Choose two.)
Answer: A,D
Explanation:
Oracle Cloud Infrastructure (OCI) is designed with a hierarchical structure to ensure high availability and fault tolerance:
Correct Answer (B): “An OCI region is a localized geographic area, and an availability domain is one or more data centers located within a region” accurately describes OCI’s architecture. A region is a standalone geographic area (e.g., US East), and availability domains (ADs) are isolated data centers within that region, enhancing resilience.
Correct Answer (D): “Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region” reflects OCI’s design for fault isolation. ADs are physically separate, minimizing the risk of cascading failures.
Incorrect Options:
A: Regions are independent, not dependent, and there’s no 5,000-kilometer restriction; they are globally distributed for latency and redundancy purposes.
C: Fault domains are subdivisions within an AD, not across regions or ADs, ensuring resource isolation within a single AD.
This structure supports robust disaster recovery and high availability.
NEW QUESTION # 89
To whom, and in which order, are dedicated Exadata Infrastructure resources provisioned?
Answer: C
Explanation:
Provisioning dedicated Exadata Infrastructure resources for Autonomous Database follows a specific hierarchical order:
Fleet Administrator, Autonomous Exadata Infrastructure -> Autonomous Container DB -> Database Administrator -> Autonomous DB (A):
Fleet Administrator provisions Autonomous Exadata Infrastructure: The Fleet Administrator, responsible for infrastructure management, first sets up the Autonomous Exadata Infrastructure (AEI), which includes the physical Exadata hardware and networking configuration.
Fleet Administrator provisions Autonomous Container DB (ACD): Within the AEI, the Fleet Administrator creates the ACD, a container that hosts multiple Autonomous Databases.
Database Administrator provisions Autonomous DB: Finally, the Database Administrator (DBA) provisions individual Autonomous Databases within the ACD, configuring them for specific workloads (e.g., ATP or ADW).
The incorrect options are:
B: The Database Administrator cannot provision the ACD before the AEI is set up by the Fleet Administrator.
C and D: The Database Administrator does not provision the AEI or ACD; these are infrastructure-level tasks handled by the Fleet Administrator.
This order ensures proper separation of infrastructure and database management responsibilities.
