질문 # 74
What is the difference between Autonomous Data Warehouse (ADW) and Autonomous Transaction Processing (ATP) databases?

A. Only ATP manages optimizer statistics.
B. Only ADW supports autoscaling
C. Only ATP supports automatic backups.
D. Only ADW uses columnar compression by default.

정답：D

설명：
ADW and ATP are tailored for different workloads:
Correct Answer (C): “Only ADW uses columnar compression by default” is true. ADW employs Hybrid Columnar Compression (HCC) for analytics, optimizing storage and query performance, while ATP uses row-based storage for transactional workloads (though HCC can be enabled manually).
Incorrect Options:
A: Both ADW and ATP manage optimizer statistics automatically.
B: Autoscaling is supported by both ADW and ATP.
D: Automatic backups are standard for both.
This reflects their design focus: ADW for analytics, ATP for transactions.

질문 # 75
What are two differentiators of Oracle Autonomous Database on Dedicated Infrastructure? (Choose two.)

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

정답：D,E

설명：
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.

질문 # 76
Which three options are available to access data in an Autonomous JSON Database?

A. NoSQL statements using Simple Oracle Document Access (SODA) drivers
B. Oracle JSON Developer tool downloaded from Oracle Technology Network (OTN)
C. REST API calls to the database (not enabled by default)
D. Regular Oracle SQL statements using a connection through the listener
E. Oracle Cloud Infrastructure console using the JSON Online Developer tool

정답：A,C,E

설명：
Full Detailed In-Depth Explanation:
Autonomous JSON Database supports:
A: True. SODA provides NoSQL-style access for JSON documents.
B: False. SQL is secondary; SODA/REST are primary for JSON data.
C: True. REST APIs are supported but require enablement.
D: True. The OCI console offers the JSON Online Developer tool.
E: False. No such downloadable tool exists for Autonomous JSON.

질문 # 77
Which statement is FALSE about setting up compartment quotas?

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

정답：C

설명：
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.

질문 # 78
What is the correct way to list all files in the default data pump directory?

A. By executing SELECT * FROM DBMS_CLOUD.LIST_FILES('DATA_PUMP_DIR');
B. Log onto ADW server and issue ls -al on the command line
C. By executing SELECT * FROM UTL_FILE.LIST('DATA_PUMP_DIR');
D. You cannot list files in the default data pump directory from Autonomous Data Warehouse (ADW)

정답：A

설명：
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.
