質問 # 103
Which Oracle package is used to load data to an Autonomous Database from object storage?
正解：B
解説：
Loading data into Autonomous Database from object storage (e.g., OCI Object Storage) relies on a specific PL/SQL package. The correct answer is:
DBMS_CLOUD (D): The DBMS_CLOUD package is Oracle’s cloud-native tool for interacting with external data sources, including object storage, in Autonomous Database. It provides procedures like DBMS_CLOUD.COPY_DATA to load data from files (e.g., CSV, JSON, Parquet) stored in OCI Object Storage buckets into ADB tables. For example, to load a CSV file sales.csv from a bucket, you’d:
BEGIN
DBMS_CLOUD.CREATE_CREDENTIAL(credential_name => 'OBJ_STORE_CRED', username => 'oci_user', password => 'auth_token'); DBMS_CLOUD.COPY_DATA(table_name => 'SALES', credential_name => 'OBJ_STORE_CRED', file_uri_list => 'https://objectstorage.region.oraclecloud.com/n/namespace/b/bucket/o/sales.csv', format => json_object('type' value 'csv')); END; This package handles authentication (via OCI credentials), file parsing, and data insertion, supporting formats like text, Avro, and ORC. It’s integral to ADB’s cloud integration, abstracting low-level operations and ensuring security (e.g., via IAM auth).
The incorrect options are:
DBMS_RPC (A): This package doesn’t exist in Oracle Database. It might be a typo or confusion with remote procedure calls, unrelated to data loading.
DBMS_LOAD (B): No such package exists. It might confuse with SQL*Loader, but that’s a separate utility, not a PL/SQL package, and isn’t used directly in ADB for object storage.
DBMS_MIGRATE (C): This doesn’t exist either. It might be a misnomer for DBMS_DATAPUMP (for Data Pump), but that’s for database migration, not object storage loading.
DBMS_CLOUD is purpose-built for ADB’s cloud-first architecture, making data ingestion seamless and efficient.
質問 # 104
Which workload is particularly suited to Oracle Autonomous JSON Database?
正解：A
解説：
Oracle Autonomous JSON Database is a specialized variant of Autonomous Database. The correct workload is:
Schema-less, document-centric (D): Autonomous JSON Database is designed for applications needing flexible, schema-less data storage and retrieval, particularly JSON documents. It’s a NoSQL-style database optimized for document-centric workloads, such as web or mobile apps storing user profiles, IoT data, or content management systems. For example, a social media app might store user posts as JSON documents { "user": "John", "post": "Hello world" }, allowing dynamic field additions without schema changes. It supports SQL/JSON queries (e.g., SELECT JSON_VALUE(doc, '$.user')), blending relational and NoSQL benefits, and auto-manages indexing for performance.
The incorrect options are:
Data Marts (A): Data marts are structured, analytical stores for aggregated data, better suited to Autonomous Data Warehouse (ADW), which excels at columnar storage and complex queries, not JSON’s flexible format.
Transactions (B): Traditional OLTP transactions (e.g., banking records) are the domain of Autonomous Transaction Processing (ATP), which uses rigid schemas for consistency, unlike JSON Database’s schema-less approach.
Data Lakes (C): Data lakes store raw, mixed-format data (e.g., JSON, CSV, Parquet) for later processing, typically in object storage, not a managed database like Autonomous JSON. While JSON Database handles JSON, it’s not a data lake replacement.
This workload leverages JSON Database’s agility for modern, unstructured data applications.
質問 # 105
Which method does NOT permit you to change the database ADMIN user's password of an Oracle Autonomous Database on Shared Infrastructure?
正解：C
解説：
Changing the ADMIN user’s password in an Autonomous Database on Shared Infrastructure is restricted to specific managed methods due to its serverless nature:
Correct Answer (C): “OS command line from the database server” is not permitted because Autonomous Database is fully managed by Oracle. Users do not have direct access to the underlying operating system or server, eliminating this as a viable option.
Valid Methods:
A: The Admin page in the OCI Console allows password changes via the “Change Administrator Password” option, a user-friendly GUI method.
B: The OCI CLI supports password updates using commands like oci db autonomous-database update with the --admin-password parameter.
D: SQL Developer can change the password using an ALTER USER ADMIN IDENTIFIED BY <new_password> command, provided the user has appropriate credentials.
This restriction ensures security and consistency in a managed environment.
質問 # 106
Which predefined service connection should you use when running lots of high concurrent queries in an Autonomous Database?
正解：A
解説：
Full Detailed In-Depth Explanation:
Service connections in Autonomous Database:
A . DBNAME_LOW: Optimized for high concurrency with minimal resources per query, ideal for many simultaneous queries.
B . DBNAME_MEDIUM: Balanced concurrency and performance.
C . DBNAME_HIGH: Prioritizes individual query performance, not concurrency.
D . DBNAME_CONCURRENT: Not a valid service name.
質問 # 107
Which can be scaled independently of the number of CPUs in an Autonomous Database?
正解：E
解説：
Autonomous Database allows independent scaling of certain resources:
Correct Answer (B): “Storage” can be scaled independently of OCPUs via the OCI Console or API, adjusting capacity (e.g., from 1 TB to 2 TB) without altering compute resources.
Incorrect Options:
A: Sessions depend on CPU and memory limits, not independently scalable.
C: Memory scales with OCPUs in a fixed ratio, not separately.
D, E: Concurrency and parallelism are tied to CPU resources and consumer group settings.
This flexibility optimizes cost and capacity management.
