NEW QUESTION # 145
Which three methods can be used to migrate your existing Oracle database to Autonomous Database? (Choose three.)
Answer: A,C,D
Explanation:
Migrating to Autonomous Database requires robust tools:
Correct Answer (B): Oracle Zero Downtime Migration (ZDM) minimizes downtime by synchronizing data and schema changes while the source remains online, ideal for critical systems.
Correct Answer (C): GoldenGate provides real-time replication, enabling near-zero downtime migration by continuously syncing data to Autonomous Database.
Correct Answer (D): Data Pump exports data and schema to dump files, which are then imported into Autonomous Database, suitable for offline migrations.
Incorrect Options:
A: SFTP with CSV files is not a comprehensive migration method; it lacks schema migration and automation for complex databases.
E: RMAN is for backup/restore, not optimized for full migrations to Autonomous Database’s managed environment.
These methods cater to different migration needs (online vs. offline).
NEW QUESTION # 146
Which three options are available to access data in an Autonomous JSON Database?
Answer: A,B,E
Explanation:
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.
NEW QUESTION # 147
Which of the following two statements are correct? (Choose two.)
Answer: A,C
Explanation:
Oracle Data Integrator (ODI) Web Edition integrates with Autonomous Database:
Correct Answer (B): “ODI Web Edition can be installed from Oracle Cloud Infrastructure (OCI) Marketplace” is true. It’s offered as a Marketplace image for easy deployment on OCI compute instances.
Correct Answer (D): “All capabilities of ODI Classic are available with ODI Web Edition” is correct; the web version retains full functionality for data integration tasks.
Incorrect Options:
A: ODI Web Edition is not limited to Oracle Linux; it runs on various platforms supported by OCI.
C: The Data Transforms Card in Database Actions uses a simplified UI, not full ODI Web Edition access.
This enhances data integration flexibility in the cloud.
NEW QUESTION # 148
To whom, and in which order, are dedicated Exadata Infrastructure resources provisioned?
Answer: D
Explanation:
Provisioning dedicated Exadata Infrastructure resources for Autonomous Database follows a specific hierarchical order:
Fleet Administrator, Autonomous Exadata Infrastructure -> Autonomous Container DB -> Database Administrator -> Autonomous DB (A):
Fleet Administrator provisions Autonomous Exadata Infrastructure: The Fleet Administrator, responsible for infrastructure management, first sets up the Autonomous Exadata Infrastructure (AEI), which includes the physical Exadata hardware and networking configuration.
Fleet Administrator provisions Autonomous Container DB (ACD): Within the AEI, the Fleet Administrator creates the ACD, a container that hosts multiple Autonomous Databases.
Database Administrator provisions Autonomous DB: Finally, the Database Administrator (DBA) provisions individual Autonomous Databases within the ACD, configuring them for specific workloads (e.g., ATP or ADW).
The incorrect options are:
B: The Database Administrator cannot provision the ACD before the AEI is set up by the Fleet Administrator.
C and D: The Database Administrator does not provision the AEI or ACD; these are infrastructure-level tasks handled by the Fleet Administrator.
This order ensures proper separation of infrastructure and database management responsibilities.
NEW QUESTION # 149
Which three options do NOT change when enabling auto scaling? (Choose three.)
Answer: A,D,E
Explanation:
When enabling auto scaling in an Oracle Autonomous Database, the feature dynamically adjusts resources based on workload demand, but certain configuration elements remain unchanged unless manually altered.
Amount of storage (A): Auto scaling focuses on adjusting CPU and I/O resources to meet performance needs. The storage allocation remains constant because it is a separately provisioned resource that requires manual adjustment via the OCI Console or API. This ensures that storage capacity is not inadvertently reduced or expanded without explicit user intent.
Parallelism settings (B): These settings determine how many parallel processes are used for query execution. Auto scaling does not modify this pre-defined configuration; it adjusts resource usage (e.g., CPU cores) without altering the parallelism framework established for the database.
Level of concurrency (E): Concurrency refers to the maximum number of simultaneous user sessions. While auto scaling can indirectly influence concurrency by adjusting available resources, the concurrency limit itself is a fixed setting that remains unchanged unless explicitly modified by the administrator.
Incorrect Options:
I/O resources (C): Auto scaling directly impacts I/O resources by increasing or decreasing them alongside CPU adjustments to handle workload fluctuations.
Number of OCPUs displayed in the console (D): While the base OCPU count remains static, the effective number of OCPUs in use (up to three times the base) changes dynamically with auto scaling, and this is reflected in the console, making this option subject to change.
This behavior ensures that auto scaling optimizes performance without disrupting foundational database configurations.
