NEW QUESTION # 141
Which native data type is used to store spatial information?
Answer: C
Explanation:
Oracle Database supports spatial data with a dedicated data type:
Correct Answer (A): SDO_GEOMETRY is the native data type for storing spatial information, such as points, lines, and polygons, in a structured format compatible with spatial queries and operations.
Incorrect Options:
B: SDO_LOCATION is not a valid data type; it may be a confusion with SDO_GEOMETRY.
C: SDO_RELATE is a spatial operator for relationship analysis, not a storage type.
D: GEO_JSON is a format for spatial data, not a native Oracle data type (though it can be parsed into SDO_GEOMETRY).
This type enables advanced geospatial functionality.
NEW QUESTION # 142
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?
Answer: D
Explanation:
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.
NEW QUESTION # 143
What two actions can you do when a refreshable clone passes the refresh time limit? (Choose two.)
Answer: C,D
Explanation:
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.
NEW QUESTION # 144
Which set of Oracle Cloud Infrastructure metrics is available only for Autonomous Database on Dedicated Infrastructure?
Answer: B
Explanation:
Autonomous Database on Dedicated Infrastructure provides unique metrics due to its Exadata underpinnings:
Correct Answer (C): “IOPS, Storage used by tablespace, Apply and Transport Lag” are specific to dedicated deployments:
IOPS: Measures input/output operations per second, reflecting Exadata storage performance.
Storage used by tablespace: Tracks storage allocation at the tablespace level, unique to dedicated infrastructure’s granular control.
Apply and Transport Lag: Relevant for Data Guard configurations, showing replication delays, available only in dedicated setups with standby databases.
Incorrect Options:
A: Transaction Count, Running Statements, and Sessions are general metrics available in both shared and dedicated environments.
B: CPU and Storage Utilization are standard across all Autonomous Database types.
D: Query Latency, User Calls, and Execute Count are also common metrics, not exclusive to dedicated infrastructure.
These metrics offer deeper insights into dedicated Exadata performance.
NEW QUESTION # 145
Which statement is NOT correct when the Autonomous Database is stopped?
Answer: B
Explanation:
When an Autonomous Database is stopped, its operational state changes significantly:
Correct Answer (C): “User with DWROLE can still access the database” is not correct. When the database is stopped, all access is disabled, including for users with roles like DWROLE (a predefined role for Data Warehouse tasks). The database is offline, and no connections or operations are possible until it is restarted.
True Statements:
A: Tools (e.g., SQL Developer, JDBC clients) cannot connect to a stopped instance because the database services are unavailable.
B: In-flight transactions and queries are terminated upon stopping, with any uncommitted changes rolled back to maintain data consistency.
D: CPU billing ceases when the database is stopped, though storage billing continues, reflecting Oracle’s pay-per-use model for compute resources.
This behavior ensures resource conservation and cost control while maintaining data integrity.
