問題 #102
You need to create a new database by using the Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI) with the following requirements: Autonomous Transaction Processing, License Included, Shared Infrastructure. Which parameter would you NOT use?
答案：B
解題說明：
Creating an Autonomous Transaction Processing (ATP) database via OCI CLI requires specific parameters:
Correct Answer (A): db-type is not a standard OCI CLI parameter for provisioning an Autonomous Database. The CLI uses parameters like db-workload to specify the type (e.g., ATP).
Used Parameters:
B: is-dedicated must be set to false for shared infrastructure.
C: db-workload is set to OLTP for ATP.
D: license-model is set to LICENSE_INCLUDED per the requirement.
The correct command might look like: oci db autonomous-database create --db-name <name> --db-workload OLTP --license-model LICENSE_INCLUDED --is-dedicated false.
問題 #103
Which Database Actions tool is used to get information about the entities in your Oracle Autonomous Database and to also see how changing an object affects other objects?
答案：D
解題說明：
Database Actions (formerly SQL Developer Web) offers tools for database management:
Correct Answer (A): The Catalog tool provides a detailed view of database entities (tables, views, schemas) and their metadata, including dependencies via the “Impact” tab. It helps assess how changes (e.g., dropping a table) affect related objects.
Incorrect Options:
B: Data Load is for importing data, not analyzing entities or dependencies.
C: JSON is a data format, not a tool; it’s supported but irrelevant here.
D: Data Insight is a separate analytics service, not part of Database Actions.
Catalog is essential for metadata exploration and impact analysis.
問題 #104
Which three statements are true about procedures in the DBMS_CLOUD package?
答案：A,D,E
解題說明：
Full Detailed In-Depth Explanation:
The DBMS_CLOUD package facilitates cloud integration:
A: True. CREATE_EXTERNAL_TABLE creates external tables for querying cloud data directly.
B: False. No DELETE_FILE procedure exists; credential management uses DROP_CREDENTIAL.
C: True. CREATE_CREDENTIAL securely stores cloud storage credentials.
D: True. VALIDATE_EXTERNAL_TABLE checks file integrity and logs errors.
E: False. PUT_OBJECT uploads files to cloud storage, not into the database.
問題 #105
What two actions can you do when a refreshable clone passes the refresh time limit? (Choose two.)
答案：B,D
解題說明：
A refreshable clone in Autonomous Database is a read-only copy of a source database that syncs periodically, but it has a refresh time limit (typically 7 days). Once this limit is exceeded, specific actions are available. The two correct options are:
You can disconnect from the source to make the database a read/write database (B): After the refresh time limit passes, the clone can no longer sync with the source. You can “disconnect” it (via the OCI console or API, e.g., oci db autonomous-database update --is-refreshable-clone false), converting it into an independent, read/write Autonomous Database. This requires a new license and incurs full costs, but it allows modifications (e.g., INSERT or UPDATE) that were blocked in read-only mode. For example, a test clone might be disconnected to become a production instance after testing.
You can use the instance as a read-only database (C): Even after the refresh limit, the clone remains functional as a read-only database, retaining its last refreshed state. You can query it (e.g., SELECT * FROM sales) for analysis or reporting without further refreshes, though it won’t reflect source updates. This is useful if ongoing read-only access suffices without needing write capabilities.
The incorrect options are:
You can manually refresh the clone (A): False. Once the refresh time limit (e.g., 7 days) is exceeded, manual refreshes are not possible. The clone’s refresh capability expires, and it can’t sync again unless recreated. This is a fixed constraint to manage resource usage in ADB.
You can extend the refresh time limit (D): False. The refresh period (set during clone creation, max 7 days) cannot be extended after provisioning. You’d need to create a new clone with a longer limit if needed, but post-expiry, no extension is allowed.
These options provide flexibility post-expiry, balancing read-only continuity and full database conversion.
問題 #106
Which is NOT needed to manage Oracle Autonomous Database with REST APIs?
答案：B
解題說明：
Managing Autonomous Database via REST APIs relies on OCI authentication:
Correct Answer (D): “Database ADMIN password” is not needed. REST API access uses OCI IAM credentials, not database-level credentials like the ADMIN password.
Required Items:
A: User’s OCID identifies the API caller.
B: Tenancy’s OCID specifies the cloud environment.
C: Fingerprint of the public key authenticates API requests with a private-public key pair.
This ensures secure, external management without exposing database credentials.
