問題 #22
What are two differentiators of Oracle Autonomous Database on Dedicated Infrastructure? (Choose two.)

A. Users have SYS privileges in the database.
B. Users can customize the OS stack and add additional packages.
C. Users are offered greater control and isolation starting at the Exadata Cloud Infrastructure level.
D. Users have OS access to the database machine.
E. Users have more control over the maintenance schedule.

答案：C,E

解題說明：
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.

問題 #23
Which two statements are true about the Oracle Cloud Infrastructure (OCI)? (Choose two.)

A. Regions are dependent on other regions and must be located within 5 thousand kilometers of each other.
B. An OCI region is a localized geographic area, and an availability domain is one or more data centers located within a region.
C. 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.
D. A single fault domain can be associated with multiple regions and availability domains.

答案：B,C

解題說明：
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.

問題 #24
Which tab in the Data Load Explore tool shows the size of the table and the number of rows and columns?

A. Data Sources tab
B. Statistics tab
C. Measures tab
D. Hierarchies tab

答案：B

解題說明：
The Data Load Explore tool in Autonomous Database helps users analyze loaded data. The correct tab is:
Statistics tab (B): The Statistics tab displays detailed metadata about a table, including its size (e.g., in MB or GB), number of rows, and number of columns. For example, after loading a CSV into a table SALES, this tab might show “Rows: 10,000, Columns: 5, Size: 2.3 MB,” providing a quick overview of the dataset’s scale and structure. It’s designed for understanding data volume and composition, aiding decisions like partitioning or indexing.
The incorrect options are:
Hierarchies tab (A): This tab shows hierarchical relationships in the data (e.g., parent-child links), not basic table metrics like size or row count. It’s more about data organization than statistics.
Data Sources tab (C): This tab lists the sources of loaded data (e.g., OCI Object Storage buckets or files), not the resulting table’s properties. It focuses on origin, not metrics.
Measures tab (D): The Measures tab defines numerical aggregates (e.g., sum of sales), used for analytics, not raw table statistics like row or column counts.
The Statistics tab is the go-to for table sizing details in Data Load Explore.

問題 #25
Which statement is FALSE about setting up compartment quotas?

A. Compartment quotas cannot be set on the root compartment.
B. Quotas set on a parent compartment override quotas set on child compartments.
C. Compartment quotas use policies that allow allocation of resources with a high level of flexibility.
D. You cannot manage quotas in a compartment unless you belong to a group that has the correct permissions.

答案：A

解題說明：
Compartment quotas in Oracle Cloud Infrastructure (OCI) manage resource allocation:
Correct Answer (D): “Compartment quotas cannot be set on the root compartment” is false. Quotas can be applied to any compartment, including the root compartment, to limit resource usage tenancy-wide. While direct quotas on the root are less common (child compartment quotas are typically used), it’s technically possible via OCI policies.
True Statements:
A: Quotas offer flexible resource limits (e.g., OCPUs, storage) via policy statements.
B: Parent compartment quotas take precedence over child quotas, enforcing hierarchical control.
C: Managing quotas requires appropriate IAM permissions (e.g., manage quotas), ensuring security.
This flexibility supports granular resource management across the tenancy.

問題 #26
You are the admin user of an Autonomous Database instance. A new business analyst has joined the team and would like to explore the Autonomous Database tables using Autonomous Database’s Data Tools. Which step should you perform to enable the new team member?

A. Create a database user with connect, resource, and object privileges.
B. Create a REST-enabled database user (with connect and object privileges) and grant the DWROLE role.
C. Create a database user with the default privileges.
D. Create an IDCS user and create a database user with connect, resource, and object privileges.

答案：B

解題說明：
Full Detailed In-Depth Explanation:
To enable a business analyst to use Autonomous Database Data Tools (e.g., Data Load, SQL Developer Web), specific permissions are required:
REST-enabled user: Data Tools rely on REST APIs, necessitating a user with REST support enabled.
Connect and object privileges: These allow database access and interaction with tables.
DWROLE role: This predefined role grants a comprehensive set of privileges for data analysis tasks in Autonomous Data Warehouse (ADW), including SELECT, EXECUTE, and data loading capabilities.
Evaluating the options:
A: Correct. Creating a REST-enabled user with connect/object privileges and granting DWROLE ensures full access to Data Tools, tailored for ADW exploration.
B: Incorrect. Default privileges are minimal and insufficient for Data Tools usage.
C: Incorrect. While connect, resource, and object privileges provide basic access, they lack the REST enablement and DWROLE’s specific analysis permissions.
D: Incorrect. An IDCS (Identity Cloud Service) user is for OCI authentication, not database-level access, and this step overcomplicates the process.
